Listening For A Lifetime
Selecting fine audio equipment such as the unit you've just purchased is only the start of your musical enjoyment. Now it's
time to consider how you can maximize the fun and excitement your equipment offers. VocoPro and the Electronic
Industries Association's Consumer Electronics Group want you to get the most out of your equipment by playing it at a
safe level. One that lets the sound come through loud and clear without annoying blaring or distortion and, most
importantly, without affecting your sensitive hearing.
Sound can be deceiving. Over time your hearing 'comfort level' adapts to a higher volume of sound. So what sounds
'normal' can actually be loud and harmful to your hearing. Guard against this by setting your equipment at a safe level
BEFORE your hearing adapts.
To establish a safe level:
• Start your volume control at a low setting.
• Slowly increase the sound until you can hear it comfortably and clearly, and without
distortion.
Once you have established a comfortable sound level:
• Set the dial and leave it there.
• Pay attention to the different levels in various recordings.
Taking a minute to do this now will help to prevent hearing damage or loss in the future. After all, we want you listening for
a lifetime.
Used wisely, your new sound equipment will provide a lifetime of fun and enjoyment. Since hearing damage from loud
noise is often undetectable until it is too late, this manufacturer and the Electronic Industries Association's Consumer
Electronics Group recommend you avoid prolonged exposure to excessive noise. This list of sound levels is included for
your protection.
Some common decibel ranges:
Level
30
40
50
60
70
80
Example
Quiet library, Soft whispers
Living room, Refrigerator, Bedroom away from traffic
Light traffic, Normal Conversation
Air Conditioner at 20 ft., Sewing machine
Vacuum cleaner, Hair dryer, Noisy Restaurant
Average city traffic, Garbage disposals, Alarm clock at 2 ft.
The following noises can be dangerous under constant exposure:
Level
90
100
120
140
180
Example
Subway, Motorcycle, Truck traffic, Lawn Mower
Garbage truck, Chainsaw, Pneumatics drill
Rock band concert in front of speakers
Gunshot blast, Jet plane
Rocket launching pad

Speakers
In order to maximize the performance of your sound system, it is important to determine the proper placement of
your speakers. Surround systems are usually composed of 5 speakers: L/R main speakers in the frontal viewing
area, L/R surround speakers aside or behind the viewing area and a center speaker in the front-center viewing
area. If you have an additional center surround speaker, that you have a 6.1 channel system. To complete a
surround system, a dedicated subwoofer usually exists to receive only the medium-low to low-end frequencies,
thus granting it the ".1" in 5.1 and 6.1 channel designations.
Speaker Placement
The center speaker should be placed either directly above, or directly below the television screen. (It is
recommended to check the specifications of your speakers for magnetic shielding prior to placing them near a
television).
The main speakers should then be placed to the left and right sides of the television at an equal distance. You
can try experimenting with slight angling of the main speakers towards the listening area, placing them closer
etc. until you feel have reached the best sound. One thing to avoid however, when placing main speakers, is
placing them so that the tweeters are significantly higher or lower than ear height.
The surround or "rear" speakers actually work best when they are placed to the sides of the listening area, or
slightly behind it along sidewalls. They can be placed in the rear of the listening area as well, but make sure they
are not too far above ear height as that compromises their overall effectiveness.
The subwoofer ideally should be placed so that it produces a good aural blend with the main speakers, producing
smooth and rich low-end output. In most cases, the subwoofer is placed in a room corner a few feet away from
door openings. If your subwoofer has a fixed crossover at around 150 to 200Hz, placing it in the front of the
room rather than a corner is recommended.

Speaker Connection
Connect speakers with AWG-16, -14 or -12, two-conductor, standard copper wire. Whether or not the wire has
MDP plugs is a matter of taste, they are not required.
The DTX-9900K has a binding post for each speaker output that accepts bare wire and MDP plugs. The simplest
way to connect the speakers is with MDP plugs, however many people prefer the use of bare wire. If using bare
wire, first loosen the plastic nuts on each speaker output until you can access the through-holes in the metal
posts. Then strip approximately a 1 /2 " of insulation from the wire ends and twist the strands so that they can
easily slide through the holes.
Notice that the binding posts are color-coded: red for positive and black for negative or ground. The speakers
should have some very similar identification on their inputs. In order to maintain correct phasing between
speakers, it is very important that each speaker connection is made with the same polarity i.e. red to red, black
to black.
Lastly, for the powered subwoofer, connect its input to the DTX-9900K's subwoofer output using a shielded RCA
patch cable. It is recommended not to use an excessively long cable in order to prevent any line hum. If your
subwoofer does not have RCA-type plugs for connection, please refer to it's manual for further instructions.

Now that your speakers are connected, it is time to connect your audio input devices. Looking at the rear panel
of the DTX-9900K you will notice several jack groupings. Below we will cover which devices are suited for
connection, and how the connections are made.
Analog Source Connections
The analog input channels are located between the digital channels and the speaker outputs. Each analog input
channel has a L/R audio and a corresponding video jack. There are four analog input channels, one analog
output channel and one loop channel (no video) available for connection. Connections are to be made via RCA-type
patch cables, preferably shielded to minimize the possibility of cable noise.

Loop Connections
An audio LOOP channel is designed to feed the audio signal out of a host device, into an external device, and back
into the host device prior to speaker output. Loop channels are typically used by mixing amplifiers to get external
effects processing applied, such as digital key control or equalization.
To connect an external device to the LOOP channel, first remove the metal LOOP BARS. It is important to store
the LOOP BARS in a safe place when they are not connected, as they are necessary for audio output when no
device is connected to the loop. After removing the LOOP BARS, connect an RCA-type patch cable from the
OUTPUT jacks of your external effects device to the LOOP IN jacks on the DTX-9900K. Connect a second RCAtype patch cable from the INPUT jacks of your external effects device to the LOOP OUT jacks on the DTX-9900K.

When you want to remove an external device from the LOOP, disconnect all INPUT and OUTPUT connections
between it and the DTX-9900K and re-insert the LOOP BARS, connecting the L/L with one bar and the R/R with
the other bar.
If no audio output is heard after reconnecting the LOOP BARS, they may
be inserted incorrectly and need to be reversed.
NOTE:
External 5.1/6.1 Channel Device Connection
In addition to the standard stereo audio inputs, the DTX-9900K also has a 5.1/6.1 channel analog input that is
designed for connecting the output from an external device with a built-in surround decoder. Because the DTX9900K's surround decoding is excellent, this input should not be favored over a straight digital connection, rather
used in the case of possible emerging technology formats or as a secondary input.
To make the connection, using 7 RCA-type patch cables, make the appropriate connections between jacks of the
same designation (as they may differ from device to device).

The DTX-9900K has two Toslink Optical Digital inputs and two Coaxial Digital inputs. These inputs are for
connecting external devices with digital output. To play and experience DTS/DTS-ES and Dolby Digital/Dolby
Digital EX soundtracks from a DVD player with the DTX-9900K's built-in decoders, the player must be connected
to one of these digital inputs or the 5.1/6.1 input listed above. Other devices such as CD players, satellite
receivers etc., can be connected to these digital inputs as well.
Whether the digital connection is an optical or coaxial connection is not important as long as the inputs and
outputs match; optical to optical or coaxial to coaxial.
To make a digital optical connection, you first need to remove the protective cap from the optical input on the
DTX-9900K. Make sure to save it for reuse when the optical input may not be in use. Some optical cables also
have a protective cap, so ensure to check both ends for removal. Connect the fiber optic cable from the DIGITAL
OUTPUT of the source device to the OPTICAL INPUT of your choice on the DTX-9900K.

Setup and Configuration
Setup and Configuration
Now that you have your speaker and external device connections made, it is time to configure the DTX-9900K for
standard operation. We will guide you through the main areas of system configuration that need to be set
correctly for standard operation. When completed, you will have navigated through all the MAIN MENU setup
screens. To get the most optimal performance and sound quality your system can deliver, please read and follow
theses instructions carefully.
Configuring Output Levels
Setting the output level of each channel is probably the most important, yet most sidestepped process in
attaining optimal surround performance. You need to adjust the CENTER and SURROUND channels so that a
given input level to any channel will produce the same output level from its speaker as that input level would
produce in any other speaker in the system when applied to its channel.
Incorrect balancing of the front LEFT and RIGHT speakers and the CENTER channel(s) usually causes you to lose
stereo spread or dialogue intelligibility. In addition, if the SURROUND speakers are too soft in comparison to your
FRONT speakers, you will not experience a realistically enveloping sound field. Conversely, if the SURROUND
speakers are too loud, the surround sounds may distractingly jump out at you.
To set the output levels, press the TEST button and move to the listening area. As the TEST TONE cycles around
the speaker array clockwise starting at the FRONT LEFT, pay close attention to the levels for variances. If any are
observed, using the MAIN MENU, navigate to the LEFT LEVEL (L-LEVEL) option and set it to 0dB. Continue
forward until you have set all speaker levels to 0dB and repeat the TEST TONE. If more variances are observed,
navigate to that speaker channels LEVEL setting and make the adjustments to get a uniform and even leveled
sound.
Configuring Your Speakers
In order for your DTX-9900K to properly adjust and distribute audio for output, it needs to know some things
about the speakers connected to it. Below we will explain the key adjustments necessary and how to make them.
Bass Management
Since it is fairly uncommon to have 5 to 6 large full-range speakers in one room, most all surround speaker
configurations employ small speakers for the surround and center channels. As this is true, it is also true that
getting high-level, deep bass from small speakers is impractical. This is especially bad for the center channel(s)
because it is often the main channel(s) in surround soundtracks that carry large amounts of low-frequency
energy.
Fortunately, because frequencies 100Hz and lower are non-directional to the ear, it is possible to move low
frequencies from channels whose speakers can't reproduce them, to channels whose speakers can.
This is accomplished by letting the DTX-9900K know the capabilities of each speaker connected to each channel.
A speaker can be designated as either small (unable to produce low frequencies) or large (able to produce low
frequencies). This designation tells the DTX-9900K which channels to feed (or not to feed) low frequencies to. If
there is a subwoofer present, that also needs to be known by the DTX-9900K so that it can let it handle the bulk
of the low frequencies.
NOTE: To help distinguish between a SMALL and LARGE speaker, no speaker
should be designated LARGE unless it is capable of extended low frequency
response at reasonably high levels without any signal distortion. Typically, only
subwoofers, floor-standing and large bookshelf designs with >12" drivers qualify.
18
Setup and Configuration
(cont.)
Channel/Speaker Designation
To set speaker size designations including the subwoofer, enter the MASTER MENU and navigate to the MAIN
(MAIN SPK) option first. Select from NONE, SMALL or LARGE to designate the main front speakers. If you
continue to navigate forward, the next channels to designate NONE, SMALL or LARGE are the CENTER (C SPK)
and SURROUND (S SPK) channels.
After designating those channels, next are the REAR CENTER (RC SPK) and SUBWOOFER (SW SPK) channels.
For these two channels, you only need to tell the DTX-9900 if they have speakers connected to them or not.
Select either NONE or EXIST to accomplish that and complete the channel/speaker designation process.
Configuring Room Characteristics
In order for your surround experience to be fully synchronized with the video playback of movies, the room
characteristics of the listening environment must be defined to the DTX-9900K. There are four settings total:
ROOM LENGTH, ROOM WIDTH, ROOM HEIGHT and ROOM ABSORPTION. Using a tape measure, obtain the room
dimensions, and briefly assess the ratio of hard, flat and dense versus soft, textured and thin surface area
(including furniture, floor covering etc.).
To set the ROOM CHARACTERISTICS, enter the MASTER MENU and navigate to the ROOM LENGTH option first.
Select a length between 2 - 9.9M.
Continuing forward in the menu, for ROOM WIDTH, select a width between 2 - 9.9M. For ROOM HEIGHT, select
a height between 1.8 - 3.1M.
Lastly, for the ROOM ABSORPTION setting, a range of 10 -90 can be entered.
A setting of 10 would imply that the listening environment has a firm majority of hard, flat and dense surfaces,
leading to extremely reflective sound activity. A settings of 90 would imply the opposite, leading to very nonreflective sound activity. In general, the more absorbing a listening environment is the smoother and warmer the
audio is. The reason being is that when soundwaves bounce off reflective surfaces, they can cause phase shift,
stereo positioning and DSP application problems. So ensure this setting is made for optimal sound quality.
Configuring Channel Delays
In order for your surround experience to be fully synchronized with the video playback of movies, the CHANNEL
DELAY settings must be set accurately to match your listening environment. The only channels that this applies
to are the CENTER and SURROUND channels.
To figure out the correct DELAY times for your listening environment, using a tape measure, measure the
following distances: front speakers to listening area, surround speakers to listening area and center speaker to
listening area. Also, note that sound travels 1 foot per millisecond.
After the above information is collected, this is how the DELAY times are deduced:
• CENTER DELAY time is the distance between the listening area and the CENTER speaker(s) subtracted from
the distance between the listening area and FRONT speakers. The number of feet is converted to milliseconds,
1 foot = 1 millisecond.
• SURROUND DELAY time is the distance between the listening area and the SURROUND speaker(s) subtracted
from the distance between the listening area and FRONT speakers. The number of feet is converted to
milliseconds, 1 foot = 1 millisecond.
Once you have the DELAY settings ready, enter the MAIN MENU and navigate to the CENTER DELAY (C. DEL)
option and enter the DELAY setting of milliseconds.
Continuing forward in the menu is the SURROUND DELAY (S. DEL) option, enter its DELAY setting in milliseconds.
Skip two menu options forward to the PRO-LOGIC II MOVIE SURROUND DELAY (PLII MOVIE S. DEL) option and
enter the same SURROUND DELAY setting as you did previously.
Continue forward to the PRO-LOGIC II MUSIC SURROUND DELAY (PLII MUSIC S. DEL) option and enter the same
SURROUND DELAY setting as you did previously.

Configuring General System Settings
Now that the most important sections of setting up are complete, we will walk you through the remaining menu
settings to complete the system configuration.
BASS level - This setting controls the level of LOW FREQUENCY BASS signals in the MASTER MUSIC OUTPUT.
The range of BASS to select from is from -10dB to +10dB. NOTE: This setting does not affect the bass level for
microphone output.
TREBLE level - This setting controls the level of HIGH FREQUENCY TREBLE signals in the MASTER MUSIC
OUTPUT. The range of TREBLE to select from is from -10dB to +10dB.
NOTE:
This setting does not affect the treble level for microphone output.
D. RANGE level - This setting controls the range of DYNAMIC COMPRESSION used to normalize the master
volume output.
Many movie soundtracks have vastly differing speech, environmental and special effects audio levels. In fact, most
movie soundtracks have dramatic audio peaks designed to punctuate the action onscreen that can be 5 to 6
times louder in volume than speech. DYNAMIC COMPRESSION is used to balance this DYNAMIC RANGE between
the lower (speech) and higher (peaks) audio levels by slightly boosting and lowering particular portions of the
audio.
The DYNAMIC RANGE can be set to either MINIM (MINIMUM), STAND (STANDARD) or MAXIM (MAXIMUM). The
MINIMUM setting applies a compression level suitable for late night viewing, greatly reducing peak levels without
reducing speech and environmental audio. The STANDARD setting applies a compression level recommended by
most audio engineers for attaining an optimal sound while preventing any possible hearing damage if heard at
high output levels. The MAXIMUM setting bypasses compression altogether, allowing for the full dynamic range of
cinema.
D.D LFE level - This setting controls the level of LOW FREQUENCY BASS sent from the SUB OUT jack to a
5.1/6.1-channel subwoofer in DOLBY DIGITAL/DOLBY DIGITAL EX audio modes.
The range of BASS to select from is 00dB to -10dB.
This setting DOES NOT affect the subwoofer bass level for DTS, DTS-ES,
PRO-LOGIC I - II, STANDARD ANALOG and KARAOKE MODE audio output.
NOTE:
DTS LFE level - This setting controls the level of LOW FREQUENCY BASS sent from the SUB OUT jack to a
5.1/6.1-channel subwoofer in DTS/DTS ES audio modes.
The range of BASS to select from is 00dB to -10dB.
This setting DOES NOT affect the subwoofer bass level for DOLBY
DIGITAL/DOLBY DIGITAL EX, PRO-LOGIC I - II, STANDARD ANALOG and KARAOKE
MODE audio output.

NOTE:
This setting only works in PRO-LOGIC II audio mode.
PLII DIMENSION level - This setting allows for gradual adjustment of the soundfield towards either the FRONT or
REAR stereo image. This is used to achieve an optimal balance of speaker output within particular PRO-LOGIC II
encoded audio.
The range of selection is from -3dB to +3dB. Select towards the +3dB for an increased FRONTAL stereo image,
and select towards -3dB for an increased REAR stereo image. Leave at 00dB for an even soundfield. NOTE: This
setting only works in PRO-LOGIC II audio mode.
PLII CT WIDTH level - This setting allows variable adjustment of the CENTER audio image. This is used to create
an optimal F-LEFT-CENTER-F-RIGHT soundfield for increased stereo positioning.
The range of selection is from 00 to 07. To have the CENTER image adjusted so that it can only be heard from
the CENTER speaker, select 00. To have the CENTER image widened to also be heard from the FRONT L/R
speakers, select 3-5. To have the CENTER image widened so that it is heard from the FRONT L/R speakers only
(also known as phantom mode), select 07.
NOTE:
This setting only works in PRO-LOGIC II audio mode.

Surround Mode Selection
Surround mode selection for cinematic audio, 5.1/6.1-channel encoded audio CD's or HDCD's is automated by
the DTX-9900K. Although the DTX-9900K's built-in decoders support DTS, DTS-ES, Dolby Digital, Dolby DigitalEX, Pro-Logic I-II audio modes, only the modes available on the disc being played will be available to the DTX9900K. This is also true when it comers to how the input source player is connected to the DTX-9900K.
Remember, DTS/DTS-ES, Dolby Digital, Dolby Digital-EX surround modes require either a 5.1/6.1-channel or
digital connection from the player to the DTX-9900K.
For example, if you play a DVD that is encoded with Pro-Logic II Surround Sound only, trying to activate the DTSES mode on the DTX-9900K will not work, even if the player is connected via a digital connection. Alternatively,
let's say you have DVD player connected with both an analog and digital connections, and you have the output on
the player set to analog, if you play a DVD movie with a DTS encoded soundtrack, when you try to select the DTS
mode on the DTX-9900K, the graphic display will scroll the channel and mode it is currently on, i.e. DVD-A PLII
MUSIC, telling you that DTS mode is not available.
If you have the correct connection made (either digital or 5.1/6.1-channel), have the player correctly configured
(either digital or 5.1/6.1-channel output) and play a disc with any of the above mentioned surround modes, the
DTX-9900K will automatically display the surround mode it is being fed i.e. DVD-D DTS-ES. If it is does not
automatically engage, pressing the AUTO DETECT button usually resolves this.

DSP Mode Selection (Music)
DSP (Digital Signal Processor) modes on the DTX-9900K are used to enhance the experience of listening to
music. Standard two-channel audio can be spread to surround and center speakers for various environmental
and acoustical sound images.
When selecting a DSP mode for music enhancement, remember that the front, surround and center speakers
should be connected, configured and working properly in order to achieve optimal sound.
To select a music DSP mode, with music playing, press the DSP button on either the FRONT PANEL or REMOTE
CONTROL. Each time the DSP button is pressed, the DTX-9900K cycles to a different DSP setting. Finding the
right DSP mode for the occasion may take a few complete cycles through the DSP modes, so don't worry if that
happens.
Since DSPs traditionally work with ANALOG signals, employing AD (analog to digital) and DA (digital to analog)
conversion, there exist different DSP settings for DIGITAL and ANALOG music signals. Below is a list of the
available DSP modes for both:
ANALOG
Live, Stadium, Jazz, Church, Hall, User, Pro-Logic Defined, Pro-Logic Movie, Pro-Logic Music
DIGITAL
Live, Theater, Disco, Jazz, Church, Hall, User, Dolby Digital EX Define

Karaoke Operations
Karaoke Mode
Karaoke mode enables all of the DTX-9900K's Karaoke functions including Digital Key Control, Echo, Repeat,
Delay and microphone use. Without Karaoke mode enabled, none of the above mentioned functions will be
accessible. Enabling Karaoke mode requires one simple press of the Karaoke On/Off button on either the remote
control or front panel.
Microphone Menu Settings
When a microphone channel needs adjustment, you to first enable Karaoke mode (if that has not been done
already). Depending on the Mic channel you seek to adjust, press either the MIC 1 button for Mic channels 1 and
2 or the MIC 2 button for Mic channel 3. Once pressed, the MIC MENU for that Mic channel will be displayed in
the graphic display. Continue pressing the MIC 1 or MIC 2 button to toggle through all the available Mic settings
for that Mic channel. To adjust a Mic setting, simply use the MIC MASTER VOLUME knob to increase or
decrease the selected Mic setting.
Mic Level
This setting controls the Mic channels VOLUME output level. Use the MIC MASTER VOLUME knob to increase or
decrease the MIC LEVEL. MIC LEVEL settings can be adjusted from 0 to 36.
Mic Bass
This setting controls the Mic channels BASS output level. Use the MIC MASTER VOLUME knob to increase or
decrease the MIC BASS level. MIC BASS level settings can be adjusted from -10 to +10.
Mic Treble
This setting controls the Mic channels TREBLE output level. Use the MIC MASTER VOLUME knob to increase or
decrease the TREBLE level. MIC TREBLE level settings can be adjusted from -10 to +10.
Mic Echo
This setting controls the Mic channels ECHO application level. Use the MIC MASTER VOLUME knob to increase or
decrease the MIC ECHO application level. MIC ECHO can be adjusted within a range of 0 to 40.
Mic Delay
This setting controls the Mic channels DELAY setting. Use the MIC MASTER VOLUME knob to increase or
decrease the MIC DELAY setting. As DELAY adjusts the total begin-to-end length of each echo interval, the more
MIC DELAY that is applied, the longer each ECHO interval will take to complete. MIC DELAY can be adjusted
within a range of 0 ms to 975 ms.
Mic Repeat
This setting controls the Mic channels REPEAT setting. Use the MIC MASTER VOLUME knob to increase or
decrease the MIC REPEAT setting. As REPEAT adjusts the number of echo intervals that occur prior to volume
fade out, the more MIC REPEAT that is applied, the more ECHO intervals will occur prior to volume fade out. MIC
DELAY can be adjusted within a range of 0 ms to 975 ms.

Using Digital Key Control
Digital Key Control allows vocalists the opportunity to manipulate a songs natural musical key to suit their own
personal vocal range and style. The Key Controller changes key values in half-step increments, and can go a total
of 6 steps up and 6 steps down.
# (UP) - Raises the musical key a half-step each time it is pressed.
(NEUTRAL) - Resets the musical key to it's original key.
d (DOWN) - Lowers the musical key a half-step each time it is pressed.
DSP Vocal Enhancement Selection
As with Music DSP modes, Vocal DSP modes are used to enhance the live vocals experience. Standard twochannel audio can be spread to surround and center speakers for various environmental and acoustical sound
images that greatly enhance a singers voice.
When selecting a DSP mode for vocal enhancement, remember that the front, surround and center speakers
should be connected for maximum enhancement.
To select a vocal DSP mode, with a microphone connected and turned on, press the EFFECT MODE button on
either the FRONT PANEL or REMOTE CONTROL. Each time the EFFECT MODE button is pressed, the DTX-9900K
cycles to a different DSP setting. Finding the right DSP mode for the occasion may take a few complete cycles
through the DSP modes, so don't worry if that happens. Vocal DSP settings includes: Reverb 1, Reverb 2,
Reverb 3, Reverb 4, Reverb 5, Echo, Hall, Live, Jazz, Disco, Music
