Introduction
The Sony DFP-3000 Cinema Processor forms the heart of the projection booth sound system in your theatre. It provide a sophisticated system for playing SDDS digital sound tracks, high quality optical soundtrack playback, comprehensive B-Chain control, and many other features. Here are just a few:
. The DFP-3000 system of projector-mounted reader and rack-mounted decoder perform traditional audio processing entirely in the digital domain. Inputs are processed with 20-bit A/D converters and then slit-loss EQ, noise reduction, and matrix decoding are all processed and adjusted digitally. After Bchain processing, fully balanced outputs are driven by 20-bit D/A converters.
. A comprehensive fallback system with two auxiliary inputs permits automatic playback of all three digital sound systems (by connecting the analog outputs of the other digital decoders into the AUX inputs of the DFP-D3000) as well as optical and non-sync inputs. You can select an AUX input to play in the event there is no SDDS digital soundtrack, a second auxiliary input to play if the first has no valid audio, and optical to play automatically if no digital soundtrack of any kind is available.
. The B-Chain system of the DFP-3000 is exceptionally flexible. It provides seven channels of multiband graphic equalization, surround delays, subwoofer parametric EQ and separate low pass filter for optical and digital play, and many other functions. These are all implemented in powerful DSP’s to make setup fast and easy using Windows-based software.
. SDDS Fader Automation lets you set levels reel by reel. Your settings are retained in non-volatile memory and automatically restored whenever that reel is played again.
. A front panel headphone monitor with selection switch lets you perform many tests using headphones or test equipment directly at the decoder front panel.
. The DFP-3000 is designed for professional applications as well as cinemas. It has balanced inputs and outputs for lowest noise and you can select professional operating references if required.

Basic checks of site and installation.
Before you begin making settings and adjustments to your DFP-3000 system, it’s best to confirm some basic conditions.
Here is a check list.
3.1 Check that the Decoder environment is suitable.
The DFP-D3000 Decoder is intended to be mounted in a rack chassis along with other cinema equipment. However, it should not be mounted in close proximity to power amplifiers or other equipment which may radiate strong magnetic fields or which give off high heat. Observe the ambient temperature limit of 40
°
C (104
°
F) and if the interior of the rack is excessively warm, provide more ventilation to lower the temperature.
n
Do not “hot plug” the Reader! The Reader gets its power through the cable that connects it to the Decoder. Do not remove or install this cable while the Decoder AC power is on. Doing so may cause damage to the Reader and void its warranty.
3.2 Confirm basic power up activity.
Connect the Reader to the Decoder using its cable. Note that this special cable cannot be cut or spliced. Connect the line cord to a mains supply of 100-240 VAC 50/60 Hz and connect the backup power supply to a mains supply for which it is rated. The LED in the SELECT switch will be illuminated Red. Switch on the Decoder. The SELECT switch LED will go out, the LCD display will be illuminated, the MASTER LEVEL numerical display will go through a brief count and then display its last +/_ dB setting. The illuminated PRESET switch shows the last and current Preset selected and the LCD display shows its name and any fallback Preset that is assigned to it.
3.3 Confirm the proper version of Decoder firmware.
The instructions contained in this Guide relate to functions and features associated with DFP-D3000 firmware versions v2.74 and higher. See TN99121401 for the latest versions of all forms of firmware and software for Sony cinema products.
The following steps illustrate how to display the DFP-D3000 firmware version on the front panel LCD screen:

3.4 Check the version of the Setup Software on your computer.
The Setup Software is updated frequently. Be sure you are using the latest version, which will be v2.00, build 2.055 or higher. You can check the SDDS web site or contact Sony Cinema Products to determine the latest version and to request a free copy. You can check the version of Setup Software you are using by launching the program and selecting Help>About. . . from the pull down menu at the top of the main screen.
3.5 Confirm a proper chassis earth ground.
Most audio grounding schemes require that the chassis of the DFP-D3000 have a solid electrical connection to the rack in which it is mounted. The finish on the rack mounting rails may be very durable. Make sure that the mounting screws cut through the finish of the DFP-D3000 and that the mounting ears make electrical connection through the rack rails’ finish to the rack itself. Test this with an ohm meter. Additionally, a screw terminal Technical Ground is available on the back panel of the Decoder, to help make a solid ground connection. Do not remove the line cord safety ground pin in an attempt to avoid ground loops. This precaution is already taken care of in the design of the DFP-D3000 and removing the pin will have no benefit, but doing so will compromise electrical safety and may violate electrical codes.
3.6 Check the optical input connector wiring.
Make sure that the optical input connector is wired according to the pinout diagram in the Appendix. Use individually shielded twisted pair cable. See Chapter 5, A-Chain Alignment, for information regarding the optical pre-amp test points. Note that the wiring of this connector may not correspond to that of other cinema processors.
3.7 Confirm proper audio interface wiring.
The Sony DFP-D3000 Decoder unit uses professionally balanced audio interface connectors, pinned according to the THX convention, for interconnections to amplifiers, crossovers, limiters, booth monitors, and other cinema processors. Unfortunately, many such devices do not employ balanced inputs or outputs. It is essential that proper balanced to unbalanced interface wiring techniques are used when connecting to these devices so as to ensure optimum operating conditions for the DFP-D3000 and connected equipment. Failure to use proper techniques in your sound rack wiring may result in reduced system headroom, improper theatre calibration, and compromised sound performance. For a guide to properly interconnecting balanced and unbalanced audio signals, refer to Tech Note TN99060401.

Note that these D-Sub connectors have metric (M2.5 x .45) jack screw receptacles and require mating connectors with metric jack screws. A kit of such connectors is provided with each DFP D3000. Do not use standard D-Sub connectors with 4-40 jack screws.
Cinema processors.
Refer to the list of available Tech Notes in the Appendix of this Guide for instructions on correct audio and logic interconnections to other cinema processors. Note that Sony connectors use the THX ® pinout convention, but other equipment may not. Therefore, pre-fabricated cables or cables made with flat ribbon computer-type cable are generally not acceptable for use with the DFP-D3000. The DFP-3000 cinema processor is capable of exceptional performance; do not degrade this by using inferior cables. Sony strongly recommends that all audio interconnections in your cinema sound rack be made using high quality audio-grade twisted pair shielded cables or individually shielded multipair cable. Contact your dealer for information regarding pre-wired audio cables for the DFP-D3000, available from several cinema accessory distributors.
Non-sync inputs.
The non-sync inputs of the DFP-D3000 are on consumer standard RCA-type connectors. One dedicated non-sync input is available. If additional non-sync inputs are required, the MIC1 input can easily be configured for line level operation, and the two eight-channel AUX inputs can serve as additional line level inputs for electronic projectors, DVD, magnetic film dubbers, and other external analog sound sources.
Microphone inputs.
The MIC1 and MIC2 inputs have built in microphone preamplifiers, so that external mixers or linematching devices are not required to directly connect a microphone level input. Input connections are balanced on a single D-Sub 9-pin female connector. 48-volt phantom power for condenser microphones is available, and can be switched on using the setup software or the front panel. See the instructions for MIC configuration later in this Guide for more detailed information.
DFP-3000
3-3
AUX inputs.
If either of the two 8-wide balanced AUX inputs are used for sources other than cinema processors, take note that the sophisticated automatic fallback system of the DFP-3000 requires these inputs to be enabled by a logic command to make them active. To use AUX1 or AUX2 for external sound sources other than digital film sound decoders, short Pin 34 (AUX1 DATA OK) or Pin 35 (AUX2 DATA OK) to GROUND on the Automation connector to enable the AUX1 or AUX2 inputs. See Tech Note TN99042801. Another approach is to chose No Fallback ( *) as the fallback option for an AUX Preset, which prevents fallback and so forces the AUX input to play whenever it is selected.
Headphones and HI output.
A single D-Sub 9 pin connector provides a L/R stereo headphone output from the back panel. This is a parallel of the front panel headphone jack and is affected by the MONITOR SELECT switch and HEAD-
PHONES level control. This connector also has two pins providing MONO outputs, which can be used to feed most Hearing Impaired transmission systems. Signal level for the HI outputs can be calibrated by an adjustment control located inside the Decoder. Detailed instructions for Hearing Impaired output level adjustment is discussed in Section 6.15 of this Guide.
Automation inputs and outputs.
All automation logic inputs and outputs are brought to a single 37-pin D-Sub connector on the DFP-
D3000. For a complete description of the connections available, see Tech Note TN99042801. Other Tech
Notes describe specific means of connecting to other types of cinema equipment; see Tech Note
TN99070701.
RS-232C connector.
This 9-pin female D-Sub connector is used to connect an external PC-compatible computer using a nullmodem cable.
RS-422 connector.
Contact your Sony service or sales representative for details on the use of this connector.
Remote level control.
Remote control of the Master Volume is possible by connecting a 100k-ohm linear taper potentiometer.
The wiring convention of this potentiometer is unique to Sony, so follow the documentation in the
Appendix carefully.
Bypass (backup) power supply.
The DFP-D3000 is provided with an external DC power supply which provides emergency power to bypass components within the Decoder. This power supply allows the Decoder to continue playing optical tracks in the event its main power has been turned off. Check that this power supply has the correct AC mains voltage rating for your country and is connected to the AC mains and to the back of the
Decoder. A small red LED in the SELECT switch on the front panel of the Decoder indicates when the unit is being powered only by the backup power supply.

Checks of correct DFP-R3000 Reader mounting.
Do not “hot plug” the Reader!
The Reader gets its power through the cable that connects it to the Decoder. Do not remove or install this cable while the Decoder power is on. Doing so may cause damage to the Reader and void the warranty.
4.1 Confirm the minimum frame offset.
Specific installation instructions for mounting the Reader to each type of projector are available in the
DFP-R3000 Installation Guide provided with the Reader. Following these instructions will ensure at least the minimum frame offset between the Reader’s LEDs and the picture gate. The Reader LED offset must be at least 32 frames ahead of the projector gate. Since the loop ahead of the intermittent affects this offset, use a nominal loop when making this determination. The maximum total frame offset possible with the DFP-3000 is 115 frames.
4.2 Check the film path alignment.
Proper alignment of the film path entering and exiting the Reader, as well as adequate tension on the incoming film, is essential to correct operation of the DFP-R3000 Reader. Carefully check that the all rollers on the in-feed mechanism, the Reader, the Adapter plate, and the projector are aligned and that no twisting of the film path occurs. Adjust the positioning of the Reader if necessary.

The most direct means of A-Chain alignment is to use with external test equipment and the controls available through the Decoder front panel. There are two approaches. The first, recommended for experienced cinema engineers, is to align the projector’s optical playback system so as to produce nominal settings (preset gain = 0.0 dB) in the DFP-D3000. This has the potential benefit of best sound quality as preamplifiers, noise reduction, and matrix decoding circuits will be operating at optimal levels. The second approach is to set the DFP-D3000 to match the existing alignments in the projector’s optical playback system. This approach has the benefit of ease of setup, but requires that the optical system is already correctly aligned. Gain trims should end up near 0.0 dB with a properly aligned projector. With either approach, it is important to first ensure a high quality optical system alignment. For detailed instructions on aligning a forward scan optical reader system, see Tech Note TN99111901; to align a specific brand of reverse scan reader, follow its manufacturer’s documentation.
5.1
The following instructions require that the projector’s optical reader has been properly aligned, the projector is mechanically sound, and its optical playback system is clean. See TN99111901 for instructions on aligning a forward scan optical reader.
The initial steps for A-Chain alignment are common to both alignment approaches.
5.2.1
Prepare a test cable.
This cable connects from a standard 1/4-inch stereo phone plug to the input connectors of your multichannel Real Time Analyzer (RTA) and simultaneously to the inputs of your dual-channel X-Y oscilloscope.
The front panel phone jack on the Decoder has line-level output signals wired with Tip = Lt, Ring = Rt, and Sleeve = audio common (ground). The Lt and Rt signals connect to each input of your RTA and to the horizontal and vertical inputs of your oscilloscope. See available Tech Note TN99101201 for details on making up this test cable.
5.2.2
Connect the test cable.
Set up your oscilloscope for X-Y display, i.e., to display phase relationships between two equal signals.
Connect the test cable to the X and Y oscilloscope inputs. Connect Lt or Rt to your RTA input. Insert the phone plug end of the test cable into the headphones jack on the front panel of the DFP-D3000.
5.2.3
Set the MONITOR SELECT switch of the Decoder to position 1 (the LCD screen will briefly display L +LC+C+SL/R+RC+SR). Set the adjacent HEADPHONES volume control to the 12:00
(straight up) position.
5.3
Enter the A-Chain access password in order to adjust preamplifier gains and set the slit loss equalization frequency. You will need to play customary alignment films at times during this process. The default
A-Chain password is “SONY”.

You must now decide whether to align the optical reader to the DFP-D3000 or the DFP-D3000 to the reader. If you decide to adjust the reader to achieve gain settings of 0.0 dB (or as close as possible) you must make adjustments to the exciter lamp voltage or reverse scan preamplifier gain, and possibly other adjustments, according to your experience. Otherwise, use the following steps to adjust the DFP-D3000 to accommodate the correctly aligned reader’s output.
5.4a
Play a Calibration Tone loop. The signal amplitude will be indicated on the L and R meters, while the single LED on the remaining meters serves as a reference. Use the Master Volume control to set the gain for the Left optical input from projector 1 (OPT1L) to match the single
LED’s as shown. Note that the meter sensitivity in this calibration mode is much higher than in normal film playback operation.
5.4b
Use the buttons to select the Right optical input (OPT1R) and use the Master Volume control to set the gain so that the signal level is correct. If you chose to align the reader to the DFP-D3000, you would have the L and R bars aligned to match the single LED’s and all gain settings would be at
0.0 dB.

B-Chain Alignment
B-Chain alignment is performed using the DFP-D3000, Setup Software, and your own test equipment. To begin, connect your computer to the Decoder using a null modem cable, launch the Setup Software, and
“connect” the Setup Software to the DFP-D3000 using the Config>Connect to DFP… menus. Set up your microphones and analyzer (THX R2 or other multichannel real time analyzer) in the theatre. Refer to
SMPTE Standard 202M, B-Chain Electroacoustic Response, for more detailed information on microphone placement, theatre acoustics, and the “X” curve. Note that the DFP-D3000 must be set up with the
Master Fader nominally set to 0.0 (not 7) and that from this position 10 dB of boost and full cut is available, with an audio/dB fader taper.
6.1
Open the Master DFP-3K Settings screen by selecting Master DFP-D3000 under the Master option in the main screen menu bar.
6.2
Ensure that the Master Volume is set to 0.0 dB. Select the appropriate output level for the DFP-D3000; this is the absolute signal level that corresponds to the _20 dBFS reference point. In most cases you should chose
_10 dBu (145 mV).
Use your real time analyzer (RTA) to check the SPL in the theatre and ensure that it is in the right range when the Master Volume is 0.0 dB.
6.3a
Move all Channel Level Trims to the center setting (0.0 dB). Center all equalizer sliders at
0.0 dB. To quickly set all EQ levels to 0.0 dB, access the Reset Channel function in the Tools pull-down menu located in the main screen menu bar. The illustration shows the main screen of the
Setup Software in this condition, for the Left output channel.

Now select each output channel in succession, confirm that the noise sound is coming from the correct loudspeaker, and adjust the channel’s equalization and level. Start by adjusting the equipment between the System Outputs of the DFP-D3000 and the loudspeakers to achieve about 85 dBC SPL in each screen loudspeaker, measured individually (82 dBC for each of the two surround channels).
This equipment may include crossovers and power amplifiers from a number of manufacturers so specific instructions cannot be given here. Sony recommends using several measurement microphones and a microphone multiplexer to drive your RTA, but each engineer will have their own preferred measurement techniques.
6.6
Adjust the graphic equalizer to achieve the “X” curve of SMPTE 202M, or other frequency response that has been established for your theatre. Do this for each loudspeaker attached to an output channel, except the subwoofer. Setting the graphic equalizer for best results requires skill and experience, but a few general points can be made. Make small adjustments and let the RTA display settle down after each adjustment. Cutting EQ is always better than boosting EQ. Adjacent bands with boost and cut differences of more than 3dB indicates problems that aren’t appropriate for EQ to correct; try to end up with a smooth equalizer setting using as little EQ as possible and no more than a few dB difference between adjacent bands. Use even less EQ on the surround loudspeakers. The screen speakers should all have the same EQ settings (if they are the same cabinet type); if they aren’t very close, there may be problems that EQ should not be used to address. Don’t boost low bands in an attempt to extend the low frequency response; that is mainly determined by the cabinet design. Remember that you can only adjust for the sound that comes directly from the loudspeakers to the measurement microphone; you cannot do much about the sound that is influenced by the auditorium acoustics or resonances and you should avoid the temptation to try to do so. If you see wide variations when you move your microphones around in the auditorium, position them closer to the front so as to measure more sound direct from the loudspeakers and have less influence from the sound that has bounced around the auditorium (which you can’t affect with EQ).
6.7
When all loudspeakers except the subwoofer have been EQ’d, make a wideband adjustment in the equipment between the DFP-D3000 and each of the loudspeakers (such as with a power amplifier gain control) to achieve 85 dBC SPL from each screen loudspeaker. This is a wideband sound pressure measurement; at this point, the individual bands of your RTA will each be at about 70 dB
SPL. The left and right surround cabinet groups should each be set for 82 dBC wideband. It is better to achieve this result with an adjustment of amplifier gain than by using a Channel Level Trim, and when using a Channel Level Trim, it is better to preserve full headroom by using attenuation (cut, or
_dB) instead of gain (boost, or +dB).
DFP-3000

6.8
To set the equalization for the subwoofer loudspeaker, press
F6 to select the Subwoofer output channel and bring up the
2-band parametric equalizer. Verify that sound is coming from the subwoofer loudspeaker cabinet.
Adjusting the subwoofer equalizer is especially difficult and benefits from experience with the particular cabinet model used. Use as little EQ as possible and allow your RTA display extra time to settle between adjustments. Aim for a smooth, rather than extended, response. Note that the higher frequencies are rolled off by the subwoofer low pass filter, whose frequency is shown below the graphic display and is indicated by the vertical yellow line. Use 330 Hz for this step and reduce the setting later, using separate settings for optical, digital, and other presets.
The analog subwoofer channel level trim affects the subwoofer output level of all eight presets. The
SDDS subwoofer level is an offset trim from this value. The AUX subwoofer offset settings are also offset from the analog subwoofer channel level trim.
6.9
The recommended method of setting the analog subwoofer level is to use the internal pink noise generator as you have previously done for the screen speakers and adjust the subwoofer power amplifier input gain control and the subwoofer level trim (which is essentially in series with the subwoofer power amplifier’s input gain control) to make the subwoofer’s RTA bands match the level of the Center channel’s RTA bands where they are flat. Use attenuation in preference to gain at the subwoofer level trim and achieve gain with the subwoofer power amplifier’s input control. When you make a change to the Analog Channel Level Trim slider while the Subwoofer output channel is selected, the software will automatically select a non-SDDS Preset.

Analog subwoofer channel response
Purists may want to set the optical subwoofer level by playing a pink noise loop and adjusting to make the overall response of the screen speakers as flat and extended as possible as a result of the subwoofer’s supplementation. This technique is beyond the scope of this Guide.
Recognize that the SDDS (and other digital formats’) subwoofer is an effects channel that delivers low frequency sounds that are designed to enhance certain elements of a particular film. The analog
subwoofer is derived from the optical L,C,R channels and is intended to compensate for limitations of the screen speakers being used; modern, full-range screen loudspeakers may need little or no analog subwoofer supplementation. For a longer discussion, see Tech Note TN99051701.
The low pass filter frequency for the optical preset must first be set to match the response of the subwoofer to the response of the screen speakers. Wide range screen speakers can have the optical subwoofer low pass filter set to the lowest value of 80 Hz; 100 Hz is a good starting point for most modern screen loudspeakers.
What ever method is used, a final listening test, using film having a high quality optical track with familiar, wide range content should be auditioned to ensure that the subwoofer level is set for best sound and optimal low frequency balance. If you use a non-sync audio source, such as a music CD, for this test, be sure to select Mode 6, 7, 8, or 9 for your non-sync Preset in the Preset Configuration
6-4 screen (see Step 6.11), so that the analog subwoofer output is active.
DFP-3000
6.10
When adjusting the SDDS subwoofer (LFE) level offset, the SDDS Preset must be made the active Preset. Select the preset manually with the Active Preset option under the Presets item in the main screen menu bar and then selecting the SDDS Preset, or by clicking the appropriate radio button at the lower left of the main screen.
8 is the default preset for SDDS. Press F6 to manually the subwoofer output channel. Alternatively, the software will automatically select the SDDS Preset when you have selected the
Subwoofer output channel and click the SDDS Subwoofer Offset slider.
Use the SDDS Subwoofer Offset slider control and your real time analyzer (RTA) to set 10 dB of inband gain of the subwoofer’s bands as compared to the previously calibrated Center speaker’s bands in the region of its flat frequency response. Be sure to allow extra time for the low frequency bands to settle to their final values.

Digital subwoofer (LFE) channel response
This procedure, which requires an RTA, matches the playback gain of the SDDS Preset’s subwoofer loudspeaker in the cinema to the playback response of the digital subwoofer (LFE loudspeaker) on the stage where the film’s sound track was mixed.
When evaluating the SDDS digital subwoofer (LFE) level, no listening test is entirely definitive, because the amount of energy in the LFE channel is a creative decision made when the soundtrack of each film was mixed. For the same reason, the digital subwoofer (LFE) low pass filter setting has no relationship to the screen loudspeakers’ performance. It merely serves to exclude undesirable sound from the subwoofer (LFE) cabinet. The actual sounds reproduced on the digital subwoofer (LFE) channel are determined by what was put there by the film’s sound mixer, as long as the filter frequency is not set so low as to remove sounds the mixer intended to be included. Setting the digital subwoofer low pass filter frequency to 100 to 200 Hz should be acceptable and either setting should sound the same when actual film is exhibited; start with 160
Hz. Subwoofer manufacturers may have specific recommendations for their cabinets.
Note that the result of a wideband SPL measurement of pink noise from the SDDS subwoofer
(LFE) will depend on both the level Trim setting and the low pass filter Frequency setting. For a
LPF frequency setting of 100 Hz, a wideband measurement made with an SPL meter will show approximately 91 dB. Such a measurement should only be made to confirm that a correctly calibrated theatre has not drifted, and cannot be used as a primary calibration measurement in place of an RTA. Also remember that the analog subwoofer channel trim is effectively in series with the subwoofer amplifier’s input gain control. This means that an adjustment to the analog
subwoofer channel trim also affects the playback level of all digital subwoofer signals.
6-5
Note that the graphic and parametric equalizer settings adjust for the frequency response of each of the loudspeaker cabinets in the theatre. This means they affect the output from all Preset inputs. The output channel level trims, including the analog subwoofer channel level trim, also affect all Presets. These settings are retained in the DFP-D3000’s non-volatile memory as a single set of overall adjustments to the playback system. Other settings, such as subwoofer low pass filter frequency and surround speaker delay, may be unique to each format or signal source.
These values are stored as individual settings for and within each of the eight Presets.
6.11
To set the surround channel delay and enable it for each Preset, bring up the Preset Configuration screen by selecting the Preset Configuration option under the Presets item in the main screen menu bar. This screen allows you to select each
Preset, make a level trim (to balance the relative level of each Preset), set a surround delay, and set the subwoofer low pass filter (LPF) frequency for that Preset.
In the latest versions of software you can also set surround delay and subwoofer LPF frequency at the main screen, according to the output channel selected.
The surround channel delay can be set with elaborate science based on SMPTE 202M. However, an easy rule-of-thumb approach is to set the milliseconds of delay for optical sources (NR2) to equal the length of the theatre (in feet) +10. For digital sources (SDDS) it should be set to 60 % of the optical surround delay.
6.12
If a cinema digital audio system is connected to one of the AUX inputs, you must set its corresponding subwoofer input level offset. The playback level of the subwoofer in today’s cinema digital audio systems is offset by 10 dB. To access the AUX Input Calibration screen, select the
AUX Inputs option from the A-chain item in the main screen menu bar. Click to select the correct offset.
6-6
DFP-3000
6.13
To adjust the synchronization between optical and
SDDS playback, access the Master SDDS
Settings screen by selecting Master SDDS from the Master item on the main screen menu bar.
First set the coarse adjustment of frame offset by counting the actual frames of film between the projector’s film gate and the LEDs of the DFP-
R3000 Reader. You must have at least 32 frames.
This adjustment cannot be changed while film is running.
Now adjust the Fine Lip Sync by playing the SDDS Installation reel or a quality, dialog-heavy feature print (not a trailer, which may have loose sync) and comparing optical and digital dialog.
Set the fine lip sync to make the two coincident. Do this by plugging headphones into the front panel of the DFP-D3000 and turning the Monitor switch to position 5 (the LCD display will briefly indicate “Lt +Rt/SOURCE_Cch”). The left output will contain the optical center channel and the right output will contain the digital center channel audio. Verify your setting by watching the film from a mid-audience position and check that the dialog synchronization appears to be correct; don’t use the projection booth monitor while looking through the booth’s port hole or you will retard the sound by about two frames.
The DFP-D3000 allows you to use this same feature to check synchronization of the AUX input signals. This means that if you also have DTS or SRD sources you can check their synchronization against the optical tracks, even though their manufacturers do not offer this capability.
6.14
Setting up Preset configurations. A Preset is a set of retained DFP-D3000 Decoder settings that apply to a particular input signal. These settings are associated with eight numbered switch buttons on the front panel of the Decoder which are used to select inputs. Pressing any of these buttons once will cause the LCD screen to display its current assignments; this is only a display function. Pressing a button twice will select its associated input as the signal source for the Decoder and will also load the corresponding Preset’s retained parameters.
Sony recommends that these default Preset assignments be Maintained, but the signal type can be renamed for convenience. For Example, AUX1 could be renamed to DTS, but keep it as Preset 6 unless you have good reason to do otherwise.

Selection area of the screen. After selecting the Preset, the various fields in the Preset Configuration area will change to reflect its current configuration. If the selected Preset is a fallback assignment for other Presets
(in the event their digital data becomes unavailable), such Presets will be highlighted in red in the Preset
Selection area. If a change is made to the selected Preset which renders it invalid as a fallback for one of its highlighted Presets, the setup software will display a warning and attempt to select another valid Preset to replace the one you have modified. A list of changes will be displayed when the modified Preset’s new configuration is sent to the DFP-D3000 Decoder. If you are using firmware v3.0 or later, check with Sony to see if changes have been made to functions available from the Preset Configuration screen.
The Preset Name edit box is used to change the name of a preset configuration. Alternate Preset names are entirely up to the user, but cannot exceed 12 characters in length. The Setup Software automatically formats the name to center it in the DFP-D3000 front panel LCD display.

For the AUX1, AUX2, and SDDS Presets, fallback Presets can be selected. To select a fallback Preset, use the edit button just below the Fallback Preset label. If no fallback is permitted for the type of input you have selected, this button will indicate Not Allowed. Otherwise, when you click on it, a selection list will pop up which shows all Presets including No Preset, with prohibited Presets grayed out to indicate they are unavailable. The SDDS Preset allows selection of a second fallback preset making it possible for all digital formats to be played automatically with optical as an overall fallback if no digital formats are available on a particular reel. For example, the fallback sequence SDDS

NR2 indicates that if SDDS data becomes unavailable, the DFP-3000 will fall back to its AUX1 input. If neither formats are available, the
DFP-3000 will fall back to its AUX2 input. Finally, if no digital formats of any kind are available, the DFP-
3000 will fall back to its optical (NR2) input. All this assumes, of course, that the other digital systems are installed and that their logic interfaces are properly wired to the DFP-D3000.
For each Preset, graphic and parametric equalization can be switched on or off, surround delay processing can be switched on or off, the number of seconds of surround delay can be set if surround delay processing is switch on, a volume offset for the preset can be specified, and the sub-woofer low pass filter frequency can be set. To select and set these parameters, use the appropriate control in the Preset Config-
uration area of the screen. If the test signal generator is running, only the preset offset, surround channel delay and EQ on/off switch controls, surround delay setting, and the sub-woofer low pass filter frequency controls are active.
After making modifications to a Preset Configuration, use the Send Config to DFP button to send the changes to the DFP-3000 decoder from your connected laptop. Even if the Send Config to DFP button is not used, the Setup Software will automatically send the new parameters to the DFP-3000 decoder when the Exit button for the Preset Configuration screen is clicked. Save these settings as a theatre file when prompted in case they need to be restored to recover from unintended changes, transferred to another processor, or reloaded to the DSP-82 board if it is ever replaced.

At this point the DFP-3000 system needs only a few final adjustments. The Preset level trims can be set according to the preferred methods of each cinema engineer. To access the trim of a
Preset from the front panel, select the Preset by pressing its button twice and then press the Down arrow. Adjust the Master Volume control to change the preset trim in order to match the Preset to the SDDS loudness level; when satisfied with the level, press the Up arrow to store the setting and return to normal operation. Some may chose to adjust external non-sync distribution amplifiers to achieve the desired level and leave the DFP-D3000 non-sync trim at 0.0 dB. If the screen has additional digital formats, play a quad format feature and block the LEDs of the various readers and use the DFP-D3000’s fallback system to automatically switch between formats, comparing loudness by listening to the booth monitor. This allows checking the fallback wiring as well as the preset level matching. Normally, it is best to use output trims on the other digital players to achieve 85 dB SPL at each speaker in the same manner as was done for the SDDS format with the DFP-D3000 (using pink noise and an SPL meter), but the Preset trims can also be used if convenient. When making this test, blocking the DFP-R3000 reader’s LEDs will allow you to confirm operation of the SDDS ACM (Analog Concealment Mode) fallback to optical or other preset.
The bypass level setting is made by adjusting two trimmer potentiometers (for Lt and Rt) located at the left of the lower circuit board inside the DFP-D3000. These are adjusted to produce the same output level to L and R when the unit is powered Off while playing a pink noise loop through the optical inputs. Remove two silver screws at the right of the front panel and swing it aside to reach these two trim controls.

Overall systems check and listening test.
The basic installation, alignment, and test of the DFP-3000 Cinema Processor System is now complete.
Before signing off on the job, the installer will want to play familiar reference films and listen in the house to confirm that all is well. It might also be a good idea to repeat the synchronization test of 6.13
with actual film. Adjust the fine lipsync if necessary; using the front panel for this will require the
“SDDS” password.

Troubleshooting
Experienced cinema engineers will have their own methods and styles of troubleshooting. Here are some tips that relate to the SDDS format and the DFP-3000 system. Check with Sony Cinema Products for a
Tech Note with more details.
Problems with playing SDDS.
First, ensure that the film actually has SDDS tracks on it. These tracks are the light blue or cyan areas at the outside of both rows of sprocket holes. The dark blue spots are very small, but you should be able to see a fine granularity in this area-not just a smooth blue area.
The first indication of problems playing SDDS titles due to poor print quality or dirty optics may be flickering of the film title displayed on the Decoder’s LCD display (SDDS Fader Automation must be enabled to display the film title). Clean the Reader optics.
The SYSTEM OK LED on the DFP-D3000 front panel indicates that battery power is OK and that the unit is properly communicating with its Reader. The DATA PRESENT LED will flash if film is running through the Reader at 24 frames/second (+/- 5%) and comes on solidly when SDDS data is being received from the Reader.
Next to the MASTER VOLUME fader is a switch labeled MUTING. If this switch is illuminated, sound does not appear at the outputs. Press it to restore sound output.
The REMOTE LED indicates that the Decoder is being controlled through its serial port, at which time the front panel controls and most of the AUTOMATION connector’s inputs are locked out. Be sure your laptop software is “disconnected”.
The Reader will turn on its bright red LEDs when the black sprocket roller is turning and it is receiving power through its cable. If the DFP-D3000 is powered and you don’t see LEDs on the Reader, check that the Reader cable is plugged in and is not damaged.
The matrix modes described in section 6.14 can be complicated. If you have channels missing, particularly the subwoofer, on a certain Preset, check that you have selected the desired matrix mode for that
Preset.
The EXT FADER button on the front panel of the DFP-D3000 enables a remote fader. If this function is active (as indicated by its illuminated switch), the MASTER VOLUME control becomes inoperative and the external fader takes over. Don’t use this switch unless an external fader is actually connected or your sound may be muted.
The PROJECTOR LEDs indicate which projector’s DFP-R3000 Reader is selected in a changeover environment, using the rear Automation connector pins. Be sure the correct Reader is selected. Optical soundtrack reader selection is also selected at the Automation connector, but has no bearing on these LED indicators.

Problems playing other digital formats.
For other digital systems to play automatically according to fallback settings or when their Preset is selected, their analog audio outputs must be correctly wired to an AUX input and their logic outputs must be correctly wired to the AUTOMATION connector of the DFP-D3000. Basically Pin 34 must be grounded for AUX1 to play and Pin 35 must be grounded to play AUX2, otherwise selecting these
Presets will play only their specified fallback sources. The same effect can be achieved in software by selecting “No Fallback” (indicated by *) as the fallback for AUX 1 or 2. This will prevent them from ever going to their fallback presets, but will also preempt selecting optical (NR2) as a fallback in the event their data fails.
If you lose sound during a show you can place the DFP-3000 into bypass by turning off its mains power at the front panel; an orange LED in the SELECT switch will come on unless the bypass power supply is not connected. When running off the bypass supply, the Decoder will play in stereo from its optical input, but without noise reduction or matrix decoding. If you lose digital sound for brief periods or if you are unable to play optical soundtracks, the first thing to ensure is that the exciter lamp is working. See Tech
Note TN99111901 for help with a forward scan optical reader system.
Use the front panel HEADPHONE output and its MONITOR SELECT switch as a quick troubleshooting aid. The signal source that is selected will be displayed on the LCD screen for five seconds after you move the selector switch to a new position.
In the event you have difficulty.

9.2 DFP-D3000 Input/Output Level
The DFP-D3000 input/output levels are as follows:
AUX input reference level:
The reference level is _8.2 dBu (= 300 mV). The signal level can be increased for other channels only for the Sub Woofer channel input. (Select from 0 dB, +6 dB, +8 dB, +10 dB).
Set this item from the setup software.
Non-Sync input reference level:
Select from +4 dBu reference, _10 dBu reference, and _16 dBu. (Set from the setup software.)
Microphone 1 input reference level:
This input can be used not only as the microphone input but as the line input (monaural) as well.
The level of the microphone input can be adjusted within the range of _20 dBu and _60 dBu.
During line input, the level can be selected from +4 dBu reference, _10 dBu reference, and _16 dBu reference. (Set from the setup software.)
The default values are _50 dBu for the microphone input, and _10 dBu for the line input.
Microphone 2 input reference level:
The level of the microphone input can be adjusted within the range of _20 dBu and _60 dBu (1 dB step).
The default value is _50 dBu.
Phantom power ( +48 V) can be supplied for both Microphone inputs 1 and 2.
PEC input reference level:
If A-chain automatic adjustment is performed using the reference film recording the 880 Hz sine wave
(film recorded with Dolby Tone) in the DFP-D3000, the DFP-D3000 meter will be set to _20 dB (20 dB below the maximum level of the digital signal processing) when the film reference signal is played back.
Reference level of the digital unit:
20 dB ( _20 dBFs) below the maximum level (0 dBFs) of digital signal processing. In digital signal processing, basically _20 dBFs will be directly output to the output if the equalizer level, trim level, etc.
have not been adjusted
Audio output level (SYSTEM OUTPUT, MONITOR OUTPUT)
Select from the _16 dB reference or _10 dBu reference. However the system can handle the +4 dBu reference output.

9.3 Changeover Settings
The following signals must be connected to control changeover from the projector.
. Connect the Motor 1 Start signal (output) of the projector to the Pin 1 Proj. 1 motor start terminal
(input) of the DFP-D3000 Automation connector. (ON at low level)
. Connect the Motor 2 Start signal (output) of the projector to the Pin 33, Proj. 2 motor start terminal
(input) of the DFP-D3000 Automation connector. (ON at low level)
. Connect the Change over command output (gate switching control signal of the projector) of the projector to the Pin 18, C/O CMD IN terminal of the DFP-D3000 Automation connector. (At the Low level, Projector 2 is selected. At the High level, Projector 1 is selected.)
. Connect the Ground signal of the projector to Pins 14 to 17 of the DFP-D3000 Automation connector
(Logic common or Tally common)
To control the changeover from the projector, set the time from the start of the motor of the projector to changeover to 7 seconds. Also set the Ramp Time (start up time) to less than 3 seconds (the faster the better).
The following shows the connections for using the DFP-D3000 data detection function for controlling the

9.4 Settings for using DFP-D3000 as DFP-D2000
The DFP-D3000 operations must be set appropriately using the setup software.
9.4.1 Conditions
When the DFP-D3000 has been added to the existing cinema processor master, do not turn off the
power of the DFP-D3000 while running the film (including film which does not record SDDS).
No sounds will be output including the existing system if turned OFF.
9.4.2 Connections and Settings when Connecting the Output of an Existing System
1. Connecting the system
Input signals from an existing system to the AUX1 input or AUX2 input for the audio system.
At the same time, connect the theater amplifier to SYSTEM OUT. Also connect the SDDS READER
(DFP-D3000) to the DFP-D3000.
Automation connection is required if changeover is to be performed or if switching to other digital formats using the DFP-D3000. The connections are as follows.

2. Setting of output preset corresponding to AUX1 or AUX2
The following shows an example of the settings of the Preset Configuration screen of the setup software.
For this example, signals from the existing system are connected to the AUX1 input.
With this system configuration, set the Fallback of the AUX input to the AUX input itself. (In other words, no Fallback operations. Details are as shown at (1) of the following setting example.) Set the EQ of the AUX input to OFF, and use an equalizer which has been adjusted at the existing system side. Set
Surround Delay in the same way. (Details are as shown at (2) of the following setting example.)
DFP-3000
9-7
3. Setting the output preset corresponding to SDDS
The following shows an example of the settings of the Preset Configuration screen of the setup software.
With SDDS, set the Fallback setting to AUX1. (Details are as shown at (1) of the following setting example.) Like the DFP-D2000, for the inputs corresponding to SDDS, EQ must be turned ON and Bchain and Surround Delay must be set.) (Details are as shown at (2) of the following setting example.)
4. Precautions for operations of the above system
. Do not turn off the power of the DFP-D3000 while running the film (including film which does not record SDDS). No sounds will be output including the existing system if turned OFF.
. Adjust the volumes of AUX and SDDS using the Output Offset setting of the Preset Configuration screen to eliminate the difference when AUX and SDDS signals are switched.
. If requiring the same operations as the DFP-D2000, set the preset switches (eight large switches on the front panel) of the DFP-D3000 to preset (Preset 8 at shipment) corresponding to SDDS.
. If the AUX input Fallback setting is not set for some DFP-D3000 setup software versions, in some cases, the Preset Configuration screen cannot be exited. In such cases, set Fallback without using the setup software. Set Fallback by selecting the preset number.

With this system configuration, do not adjust the B-chain of the DFP-D3000 in order to use the B-chain function of the existing cinema microprocessor. To prevent accidents, set the EQ setting at the Preset settings to OFF. (Refer to (2) in the example of settings screen.) To send signals to the AUX input of the
DFP-D3000 from another cinema processor, the AUX input connected to that signal can be selected as the Fallback setting.
9-10
DFP-3000
3. Setting of output preset corresponding to AUX1 or AUX2 (Optional)
Set the Fallback of the AUX input to the corresponding AUX input (so that the Fallback function does not operate). Set the AUX input equalizer setting to the same setting as the SDDS format. The following shows an example of the settings of the Preset Configuration screen of the setup software.
4. Precautions in operations on the above system
. Use the DFP-D3000 master control at 0.0 dB. However, if the signal level of the SDDS input must be controlled at the DFP-D3000 according to the settings of the existing system, adjust the master control.
. Always set the preset switches (eight large switches on the front panel) of the DFP-D3000 to the preset
(Preset 8 at shipment) corresponding to SDDS. If film sound processor other than the DFP-D3000 are connected, select the preset corresponding to the external processor or the preset corresponding to the
SDDS as necessary.
. In some cases, the Preset Configuration screen cannot be exited if the AUX input Fallback setting is not set for some DFP-D3000 setup software versions. In such cases, set the Fallback function without using the setup software. In this case, set the Fallback by selecting the preset number.

9.6 Connecting the CP-500 and DFP-3000
When constructing the system by combining the Dolby Laboratories CP-500 and DFP-D3000, as both are equipped with analog pickup interfaces and system control terminals, the functions of both equipments will clash.
It is therefore important to decide which to master depending on ease of constructing the system and uses by the customer. This document describes both the connection when using the DFP-D3000 as the master and the connection when using the CP-500 as the master.
9.6.1 Connecting the DFP-D3000 to the CP-500 with the DFP-D3000 as the master
The advantage of this connection is that the merits of the DFP-D3000 such as high sound quality equalizer circuit and digital signal switching can be put to full use.
The disadvantages on the other hand are; because the CP-500 is unable to output SR-D format OK/NG switching signals at the voltage level, the Fallback control circuit of the DFP-D3000 cannot be used as it is. The same effects can be obtained by using an optional board (cat. 684 card) outputting pulses and performing preset switching of the DFP-D3000 according to the preset switching of the CP-500.
In this case, connect the analog track (PEC) and input from the cinema processor other than the CP-500 to the DFP-D3000, and also connect Fallback if necessary. This means that the CP-500 side is dedicated to playback in the SR-D format.
In this case, the following restrictions apply to both the DFP-D3000 and CP-500.
DFP-D300: Firmware version 2.60 and higher
CP-500: CP-500 units with firmware v1.51 or higher and control board Cat. 684 is installed.
If the software of the DFP-D3000 or CP-500 is older than the above, contact a Dolby Laboratories dealer for the CP-500 and a Sony service center for the DFP-D3000 to upgrade the firmware to the latest version.

The inputs of the DFP-D3000 are professionally balanced, whereas the outputs of the CP-500 are not.
Therefore shielded wires should be connected to all DFP-D3000 audio grounds.

4. Procedures for setting up the CP-500
First, confirm that the CP-500 is equipped with firmware version 1.51 or higher.
Next, enable the “Auto Digital” function by referring to the CP-500 Installation Manual. The source format of the “Auto Digital” function should be set to Dolby A (SK2), and the target format to Dolby
Digital (SK4). It is crucial that Dolby SR (SK3) is not assigned as a source format of the “Auto Digital” function. These instructions assume that the CP-500 preset is configured for Dolby A on SK2, Dolby SR on SK3, Dolby Digital on SK4 and Non Sync 1 on SK6.
Set the level of all output channels of the CP-500 to the DFP-D3000 AUX Port input reference level.
( _8.2 dBu. This value is equivalent to _10 dBV or 300 mV.)
During operation, ensure that the master fader on the CP-500 is disabled or kept at 7.0 at all times.
5. Setting up the DFP-3000
First, confirm that the DFP-D3000 is equipped with firmware version 2.60 or higher.
The DFP-D3000 is configured for SDDS on Preset 8 and that Dolby Digital is on Preset 6 (using the
AUX1 input). We recommend that you don’t change Preset assignments from the defaults unless there is a strong requirement for doing so. If Preset assignments are to be changed, we recommend setting up the theatre completely and confirming that all is working correctly before making the reassignments.
In this system, set the fallback structure corresponding to the SDDS input (Preset 8) of the DFP-3000 as follows. The Preset Configuration screen of the Setup software will display as follows. ((1) of the following diagram.)
SDDS

DFP-3000
If equalizer adjustments for B-chain have been performed on the CP-500, set the equalizer setting of the corresponding preset (Preset 6) of the DFP-D3000 to “OFF”. In the same way, if the Surround Delay is set at the CP-500 side, set the DFP-D3000 Surround Delay to “OFF”. The Preset Configuration screen of the Setup software will display as follows. ((2) of the following diagram.)
Generally, as the equalizer and delay quality of the DFP-3000 are better than CP-500, use the DFP-3000.
The preset fallback setting corresponding to the CP-500 can be left at the default setting. (Because it is fixed to prevent hardware fallback.)

6. Using as the changeover system
When using the system combining the DFP-D3000 and CP-500 in the changeover format, it is necessary to supply the motor start pulse and change over command signals for the CP-500 as well. Therefore, add the following signals to the control signal line and connect the cables.

9.6.2 Connecting the DFP-3000 to the CP-500 with the CP-500 as master.
When using the CP-500 as the master, use the DFP-D3000 for only the playback of the SDDS. This setting has the following problems.
1.
The CP-500 input and output are unbalanced while those of the DFP-D3000 are balanced, therefore compared to the CP-500, effects of external noises are less.
2.
The powerful theatre control features and easy setup of the A- and B-chain of the DFP-3000 will be disabled.
3.
Channel level trims of the CP-500 will affect the SDDS channels.
4.
The CP-500 analog bass and treble controls will also affect SDDS playback.
However, when using the CP-500 as the master in consideration of the ease of operations, set the CP-500 and DFP-D3000 as follows.

The outputs of the DFP-3000 are professionally balanced, whereas the inputs of the CP-500 are not.
Therefore all DFP-D3000 audio grounds should be connected to shielded wires.
4. Setting up the CP-500
On the CP-500, make a custom user format derived from Format 5 (SR). Then change the settings of the
CP-500 as follows. (For details, refer to the instruction manual of the CP-500.)
(1) After copying existing format (5), press “Accessory Rack” and select “Xmit/Receive enable”
(2) Press “Channel Mute”. Two cross point tables appear.
(3) Open all cross points.
(4) The first cross point table is called “Accessory rack”. Connect the corresponding channels. (For example, connect the input Left Channel to the output Left Channel. Set other channels in the same way.)
(5) The second cross point table (named “Normal”) should be left open.
(6) Save the user format as User 1 (or another name) and configure the format selector so that this user format is assigned to SK6.
With the Automation wiring specified above, if SDDS data is normally detected even once, the DFP-
D3000 will send signals to the CP-500 SK6 so that SDDS input sounds are output.
The user format set this way is not set as the source of the audio digital function of the CP-500. Therefore each time films on more than two digital formats are played back, the SDDS playback is interrupted, and the SR-D format sound is played back.
9-24
DFP-3000
5. Audio input/output level adjustments
Since the channel output adjustment and output bass and treble adjustments of the CP-500 is done on the output board (in the analog domain), these settings will also affect SDDS. Therefore, adjust the B-chain of the CP-500 prior to the B-chain of the DFP-D3000.
To obtain an optimum gain structure, select _10 dBu reference as the DFP-D3000 reference output level, and increase the channel level trims to approximately +2 dB to match the 300 mV reference input level of the CP-500.
With this set-up, the master fader of the CP-500 will not affect the playback levels for formats played through the DFP-D3000 and vice versa.
6. DFP-D3000 settings
Basically, as the DFP-D3000 is used only for SDDS reading, use it at the shipment settings. Do not adjust the DFP-D3000 equalizer and surround delay settings, but set them at the CP-500. It is recommended that the DFP-D3000 SDDS Preset (Preset 8) EQ and Surround Delay settings are set to OFF.
7. Using as a changeover system
When using the system combining the DFP-D3000 and CP-500 in the changeover format, it is necessary to supply the motor start pulse and change over command signals for the CP-500 as well. Therefore, add the following signals to the control signal line and connect the cables.

9.8 Corresponding to DFP-D3000 Surround EX
9.8.1 Restrictions on Control of Surround EX Decoder
1.
For Surround EX, information for expressing “Surround EX” on film in any digital format is not written. For this reason, when controlling the Surround EX processor, there is a need to control the
Surround EX decoder from the DFP-D3000 only when processing the Surround EX decoding for the
SDDS signal.
2.
When performing Surround EX decoding for other digital formats, accurate control from the DFP-
D3000 is not possible. In this case, use the control signal from each equipment. Due to effects of the fallback operation on the DFP-D3000, operations may not be smooth in some cases.
3.
The DFP-D3000 software must be changed to a version above V2.61. If B-chain settings have already been completed, change the setup software version for the DFP-D3000 to V2.00 build 2.044
or above, and read out the set data before upgrading the version. After upgrading the version, re-send the read out data to the unit.
For DFP-D3000 models shipped after September 1999, use the software provided at shipment.
9.8.2 Connections of Audio System
Connect the audio system as follows.
Of the DFP-D3000 audio outputs, connect the Surround Left output and Surround Right output to the SA-
10 Surround input. To connect the Surround outputs of the SA-10, connect the four outputs from the SA-
10 (Surround Left, Surround Back-Left, Surround Back-Right, Surround Right) to the speaker via the power amplifier according to the SA-10 manual. In this case, use the switching circuit in the SA-10 to turn ON and OFF the Surround EX mode to switch the sounds.
The following restrictions apply in the combination with the V2.61 software.
. At the DFP-D3000 side, as the EQ setting cannot be changed for every preset, if combining with the
Surround EX processor, adjust the level and equalizer of the surround channel at the Surround EX processor side.
(In other words, for the surround channels, adjust the B-chain using the Surround EX processor.)
Therefore at the DFP-D3000, turn OFF the equalizer of the surround channel, and at the same time, adjust the offset of the surround channel level so that the output level of the surround channel becomes
_16 dBu. When adjusting the sound level, set the amplitude to a high level at the power amplifier.
. For channels other than the surround channel, adjust the equalizer at the DFP-D3000 side.

9.8.3 Actual Connection of Control System
When controlling operations of the Dolby Laboratories SA-10 (Surround EX processor) from the DFP-
D3000 (switch the Surround EX mode between ON and OFF), connect the control input connector on the rear panel of the SA-10 and Automation connector on the DFP-D3000 as follows.
1. Settings at the SA-10 (Surround EX Processor) side
. Set the control mode switch SW1 (located on the daughter board) in the SA-10 to the “CP65” position.
. Push in (Normal position) the “Alignment Switch S602” on the rear of the SA-10 front panel.
. Set the “Surround switch” on the SA-10 front panel to the “Enable” position.
2. Connections of the Control Cable Between the DFP-D3000 and SA-10
. Connect Pin 14 (Logic Common) of the DFP-D3000 Automation connector to Pin 12 (GND) of the
Control Input connector of SA-10.
. Connect Pin 32 (SDDS OK) of the DFP-D3000 Automation connector to Pin 4 (CTRL 4, EX decode mode) of the Control Input connector of SA-10.
. Connect Pin 36 (ACM) of the DFP-D3000 Automation connector to Pin 2 (CTRL1, non decode mode) of the Control Input connector of SA-10.
With this connection, the signal for indicating the read state of the SDDS is sent to the SA-10 control signal input which is the Surround EX Processor, and the SA-10 operations are controlled via the control cable according to the SDDS signal state.

9.8.4 SA-10 Operations When Controlling from the DFP-D3000
The system combining the DFP-D3000 and SA-10 performs the following operations at the settings and connections described until now.
1. When the SDDS film is played back
The following operations are performed when the SDDS film is played back.
When the SDDS film is identified by the DFP-D3000, the SDDS OK pulse is output from Pin 32 of the
Automation connector. As a result of sending the pulse to the SA-10 control input, the “Surround EX
Mode” LED lights up on the Surround EX Processor SA-10, and the Surround EX decode function turns
ON (EX mode).
If there are large scratches on the SDDS film, or if film with no SDDS signal arrives and SDDS signal cannot be read, the ACM pulse is output from the Pin 36 of the Automation connector. As a result, the
“Surround EX Mode” LED lights up on the Surround EX Processor SA-10, and the Surround EX decode function goes OFF (normal mode).
2. When other format film is played back
In this case, even if the Surround Mode switch on the SA-10 front panel is set to the “Surround EX
Enable” mode, the “Surround EX Mode” LED lights up on the Surround EX Processor SA-10, and the
Surround EX decode function goes OFF (normal mode).
n
Even other format sounds (Dolby Digital, DTS, Dolby SR) are played without selecting the SDDS sound in the use of films recorded with SDDS, Surround EX control will be performed using the read state of the SDDS data. This must be borne in mind carefully.
9-40
DFP-3000
9.8.5 Controlling Surround EX from DA-20
When combining the Dolby Digital format decoder Dolby Laboratories DA-20 and DFP-D3000, the
SDDS decoder DFP-D3000 should be used instead of the CP-65 and CP-55 Dolby Laboratories Cinema sound processors. For the DFP-D3000, as Dolby Digital format conditions are detected using the level signal (method of determining the OK/NG state of the digital format according to the High/Low state of the terminal voltage) as done in the Dolby Laboratories cinema sound processor CP-200, operations will be different from the current Dolby Laboratories cinema processor (adopts pulse signal input).
To control surround EX from the DA-20, use the following method.
1.
Since the DFP-D300 is designed so that the designated operations are performed when it receives the
Dolby Laboratories CP-200 control signal (voltage level output method), set the DA-20 operations in the same way as when CP-200 is used. For reference, a diagram showing the connection of the DFP-
D3000 and DA-20 is shown on the next page.
2.
Distribute the signal sent from the DA-20 from the DFP-D3000 Automation connector, convert the signal to a pulse signal, and send to the SA-10 control signal input. In this case, use the signal conversion adapter Cat. 845 available from Dolby. Connect this adapter to the SA-10 Control Input terminal (J3). Specifically, connect DA-20 and DFP-D3000.

Note that with the Cat. 845 adapter, true level signals are not converted to pulse signals (level signal components are continuously output). As a consequence, SA-10 cannot be controlled simultaneously from all digital formats. To control SA-10 from other formats, stop the Cat. 845 operations. For details on the Cat. 845, contact Dolby Laboratories or a Dolby Laboratories Dealer.
At such settings, when Dolby Digital format signals are read correctly, the Surround EX decoder will operate and Surround EX decoding is performed. If the Dolby Digital format signals are not read correctly, Surround EX decoding will not be performed. In this case, when preset is selected but the Preset corresponding to the Dolby Digital format signal is not selected correctly, Surround EX decoding may be performed where not needed.
To control SA-10 from the DFP-D3000, third party solutions are available from a variety of outside vendors and suppliers of cinema equipment, such as Smart Devices Inc (USA), Hasso GmbH (Germany) and others. Contact the vendors directly for the latest information about their available products.

9.8.6 Controlling Surround EX from DTS-6 or DTS-6D
When using the DTS Co. DTS-6 or DTS-6D in the DFP-D3000 system, SA-10 operations can be controlled from these cinema processors (DTS decoder) in the DFP-D3000 system.
In this case, connect the control cables of the DTS-6 or DTS-6D and SA-10 as follows. In this case, the
SA-10 can be controlled regardless of the DFP-D3000 control cables.

Connect Pin 6 “Force SR +” and Pin 9 “+5V Output” of the Automation connector.
Connect Pin 19 “Force SR _” and Pin 22 “5V GND” of the Automation connector.
9.8.7 Controlling Surround EX control from Automation Controller
When fallback using several digital formats is adopted in the DFP-D3000 system, or the SDDS signal cannot be read, it is necessary to cancel the SA-10 Surround EX decoding operations as soon as possible.
It is also necessary to ensure compatibility for films not recorded with the Surround EX signal. By changing the preset settings of the DFP-D3000, and preparing preset using the Surround EX not corresponding to the SDDS input and preset not using the Surround EX (same as the Dolby Laboratories CP-
500), Surround EX can be controlled from an external Automation controller. The examples of preset settings and connection methods of control cables are shown on the next page onwards. However when using this connection method, set the Processor Select switch in the SA-10 to the CP-500 side.

9.8.8 Adjustments of Audio System
Details of the connections and adjustments of the audio system are provided in “Connections of the Audio
System”. Below, the adjustment methods are described.
Of the DFP-D3000 audio output, the Surround Left output and Surround Right output will be connected to the Surround input of the SA-10. Currently, as the EQ setting cannot be changed for each preset in the
DFP-D3000, when combining it with the Surround EX processor, adjust the level with the equalizer of the surround channel at the Surround EX processor side. In other words, perform B-chain adjustments using the Surround EX processor for the surround channels.
For the Surround EX processor, if the level of signals input to the surround processor is not adjusted properly, the designated surround effects cannot be obtained. For this reason, there is a need to adjust the level of signals sent to the Surround EX processor from the SDDS.
The following describes the procedures for setting the level of the signal output from the DFP-D3000 to the Surround EX processor, and the equalizer.
Equipment required
. Personal computer installing the DFP-D3000 setup software
. Interlink cables (cross cables and all pins must be cross connected)
. Audio level meter (or AC voltmeter)
Adjusting/setting procedures and measurements
1.
Connect the DFP-D3000 and personal computer using interlink cables. When using a commercially available interlink cable, as male D-Sub 9 pin connectors are provided at the two ends of the cable, it is necessary to change only the DFP-D3000 side to the female connector. In this case, use a commercially available polarity converter connector (gender changer) to convert the connector shape. As the
DFP-D300 uses mm screws (ISO standard) for fixing the connector (side secured by the screws), when using cables for the PC, the adjustment/setting/measurement can be done more easier if the fixing screws at the connecting side of the cable to the PC is removed.
2.
Turn on the power of the DFP-D3000 and Surround EX processor. Turn the power of the power amplifier until level adjustments complete.

16. Click “Master” of the “Channel Mute Status” to unmute the master volume, and then adjust the Bchain (surround adjustment: adjustment of frequency characteristics and level) according to the
Surround EX processor manual at the Surround EX processor side (and amplifier level adjustment knob). If pink noise must be generated at the Cinema Processor side, generate pink noises from the
DFP-D3000 setup software.
17. Perform all adjustments of the B-chain other than the Surround output as done normally at the DFP-
D3000 side.
18. After completing all adjustments, click “Disconnect to DFP” from the Config menu on the setup software, end communication with the DFP-D3000 to end the setup software.

n
It is also possible to play film recorded with Dolby tone instead of the built-in oscillator to adjust the output level of the DFP-D3000. If SDDS format film with such tones are not available, use a Dolby
Digital format or analog film and switch the preset according to the film used.
In this case, open the “Preset Configuration” in the “Preset” menu, set the “Offset Trim” setting of the preset number corresponding to the format of the film played back to 0 dB before performing the actual adjustments.
When performing adjustments, also switch the preset setting according to the corresponding film format at “Current Preset-Select to Activate” at the bottom left of the channel adjustment screen.
As of December 1999, there is no film for adjustment recorded with Dolby tones in the SDDS format.
Therefore use the Dolby Digital format or analog format level film or use the built-in oscillator of the
DFP-D3000.
One of the reasons for why this manual recommends the use of the built-in oscillator is because; effects of the offset trim setting at each preset may be received during adjustments when the Surround EX processor is added to the existing equipment.
(When the offset trim is set, there may be a difference between the reference level ( _20 dB) in the unit and the level of the signal from the film used for adjusting the signal level). When the built-in oscillator is used, the effects of the offset trim setting are not received.

9.9 Test Cable for Performing A-Chain Adjustment
The DFP-D3000 provides a convenient, front-panel phone jack with a selector switch. This jack can be used to connect a spectrum analyzer (RTA) and X-Y oscilloscope to facilitate A-Chain calibrations and adjustments. The following diagram shows the connections of the cables for connecting the spectrum analyzer and X-Y oscilloscope to the DFP-3000 headphone.

9.10 Adjusting the Analog Track Pickup
Digital audio tracks set a very high standard of quality for theatrical sound playback. In order to minimize the difference between sound from digital tracks and sound reproduced from a film’s optical tracks, the proper skills as well as caution are required for ensuring the best performance of the optical reader. This chapter mainly describes the forward scan reader. As reverse scan readers have related adjustments which may be slightly different for each brand, contact the appropriate manufacturer for specific instructions.
When adjusting the optical reader, follow the adjustment method indicated in the manual of the reader used.
When adjusting A-Chain inputs, it is not necessary to provide commands to the Automation system of the projector if the exciter lamp of the analog surround track is lit. (Only when the exciter lamp is off must the Automation system be operated to light the exciter lamp.) The exciter lamp voltage should normally be set to 75-85 % of its rated voltage as recommended by the manufacturer. As the following adjustments typically interact with each other, they must be rechecked after initial settings.
9.10.1 Preliminary Preparations Before Adjustments
First thoroughly clean the sound head optics. Replace the exciter lamp if it is discolored or if it is not sufficiently bright across the width of the slit and when its light falls on a white card held about an inch in front of the optics. Be sure that the solar cell is mounted 1 mm away from the film. The most common causes of uneven illumination are misaligned optics, dirty or aged exciter lamp, dirty optics or slit, and running of the exciter lamp at a voltage that is too low.
9.10. 2 Lateral Film Guide Adjustment
The next step in adjusting the projector’s optical reader is to ensure that the optical pickup is correctly adjusted to the optical tracks on the film. This is done by playing a loop of the SMPTE Buzz Track test film and adjusting the projector’s lateral film guide for equal and minimum high and low frequency sound from the left and right outputs. If you are adjusting an overscanning reverse scan reader you can also perform this adjustment using the X-Y oscilloscope by equalizing the perpendicular X and Y traces.
9.10.3 Lateral Exciter Lamp Adjustment
Next in setting up a forward scan reader, roll a Cat. 97 “left/right” or “crosstalk” loop and observe the signal when the film is run using a dual trace oscilloscope. Adjust the lateral position of the exciter lamp to equalize the left and right output signal levels. Generally this adjustment can be facilitated by setting so that the two channels overlap on the oscilloscope.
9.10.4 Lateral Solar Cell Adjustment
While playing the left/right loop, adjust the lateral position of the solar cell so as to achieve minimal crosstalk between left and right output outputs. Generally, this adjustment can be facilitated by setting so that two input states can be observed separately on the oscilloscope.
9-52
DFP-3000
9.10.5 Vertical Adjustment of Exciter Lamp
For forward scan readers, set the oscilloscope to the X-Y display mode, and connect the same signals to the RTA (real time analyzer, spectrum analyzer). Play a loop film recorded with (black-and-white) pink noise signal, and adjust the output level from the analog pickup to the point where the highest frequency characteristics become. If necessary, adjust to the preferred frequency characteristics.
9.10.6 Slit Lens Adjustment
Adjust the focus of the slit lens of the pickup where the frequency characteristics of the pink noise becomes the flattest. Rotate the slit lens so that the phase difference becomes minimum on the X-Y oscilloscope, and adjust the azimuth of the slit.
9.10.7 Double Checking of Illumination Inconsistency
Even illumination from the slits is essential to reducing high level distortion and in the decoding of surround signals from the Lt/Rt. Falloff at the outside edges will result in high frequency loss and playback that sounds muffled. Assuring proper playback of high levels is especially important, as modern analog track cameras can readily print stereo tracks at 130 % modulation without loss of the septum, and this extra range is commonly utilized.
To check for proper illumination, play a 100 % modulation alignment film, such as the Cat. 97 left/right film, and also a 50 % or 60 % modulation alignment film, such as the Cat. 69T. The levels of the left signal and right signal should be equal to each other when playing either film. If they are not, the slit image is imperfect in illumination flatness or in its alignment on the solar cell. The result will be distortion of loud sounds and leakage into the surround speakers.
This same test can be done using the old evenness of illumination test film, also called the “snake loop” or in Europe “scanning beam,” (SMPTE Test Film No. P35-SB) though this film was designed for mono solar cells. The most direct means of testing for evenness of illumination may be the Cat. 566 Illumination Uniformity test film. This film does not have conventional stereo tracks; instead it has six tracks of
100 Hz to 4 kHz spread across the entire optical track area. The Lt and Rt outputs are to be summed and sent to a spectrum analyzer, where the relative heights of the six bands gives direct indication of illumination of the slit across the entire solar cell.
9.10.8 Wiring Check
As a basic wiring check, slowly block the reader’s sound lens and note that the right channel level drops before the left channel.
This completes the mechanical adjustments of the analog track reader, but remember that these adjustments interact and it may be necessary to repeat these procedures to obtain the very best performance.
