Overview
Nuoptix Solid State Digital Audio Systems are the worlds most widely used solution for
ultra high quality and high reliability professional digital audio sound applications such
as theme park rides, parades, and announcement systems. Nuoptix solid state digital
audio systems can be synchronized to virtually any timecode based system such as
SMPTE. Nuoptix digital audio systems provide true audiophile quality without limitation
on the number of channels or run time. Nuoptix systems can provide theme park wide
or full parade synchronization using a single Nuoptix DTMF based broadcast
synchronization signal. Nuoptix systems are compatible with all professional and PC
based digital audio recording and editing systems. Furthermore, the Nuoptix modular
design approach provides complete flexibility in system design. For applications from a
single 5 second sound effect to a 100 channel 96 minute long theme park wide sound
extravaganza locked to film running 50 times a day for the next 20 years, Nuoptix is the
solution.
Nuoptix manufactures three varieties of digital audio packages.
1) A 5 channel, 1¾" tall (standard 1U 19" rack mount) system.
2) A 16 channel, 5¼" tall (standard 3U 19" rack mount) system.
3) A stereo channel, 2" tall x 4.6" wide x 10½ deep unit.
All electronics are contained on 4½" x 6" plug in cards to facilitate programming.
Both versions provide up to 96 minutes of 16 bit high quality audio per channel using
currently available Compact Flash (CF) memory modules. All channels can be
synchronized to "follow timecode". The timecode can be either Nuoptix DTMF timecode
or SMPTE 30 frame non-drop timecode. Channels not used to "follow timecode" can be
used for synchronous or non-synchronous applications. These channels are triggered
by a simple external "closure to ground". The units can also accept RS232 commands
for control in applications not requiring timecode synchronization.
Multiple units can be controlled/synchronized by a single timecode signal. These
systems were designed for remote multi-channel synchronous operation such as
parades with FM broadcast using the Nuoptix DTMF timecode synchronizing signal. A
narrow bandwidth FM channel is all that is required to transmit the Nuoptix DTMF
timecode signal. This system is applicable to any remote and multiple-channel solid
state digital audio application.

Card Installation and Motherboard Jumpers
Install the C992 timecode reader/controller card in slot J0 with the components facing
upward. Install the remaining slots with the required number of Nuoptix C990 audio
cards starting with J1 and going up to J5. If timecode or RS232 commands are to be
used, the associated audio card must be installed first starting with J1. Any channels
triggered by a "closure to ground" must be installed after the timecode/RS232 channels.
Remove the top cover by unscrewing all the screws on the top cover.
Each audio channel has three shunt settings, W?A, W?B and W?C where '?' is the
channel number. For channels that are to be triggered externally, via a "closure to
ground", place all three shunts over the right two pins.
For all other channels, place the shunts over the left two pins.
If all 5 channels are to be used with timecode or RS232 control, place a shunt over the
right two pins of W6 (labeled OUT); otherwise, set shunt over the left two pins (labeled
IN). Now you can put the top cover back on.
Operation
Power the unit ON by toggling the power switch on the rear panel to the ON position.
The unit will default to the NORM mode as indicated by the light above the NORM
switch on the front panel.
NORM mode: When in the NORM mode the synchronous channels will "follow
timecode" or accept applied "RS232" commands depending on the application.
The non-sync channels can be triggered by an external "closure to ground" on
the appropriate input pin. The light above the NORM switch will be lit.
TEST mode: When the TEST button is pressed the unit will start all synchronous
channels from the beginning and will ignore external timecode and RS232
commands. These channels will play to the end and loop continuously. The
remaining non-sync channels will not play by pressing the TEST button. They
will only start with an external input as mentioned above. The light above the
TEST switch will be lit.
STOP mode: When the STOP button is pressed all channels will stop. All
synchronous channels will ignore external timecode and RS232 commands;
however, the remaining non-sync channels can be restarted with an external
"closure to ground" after the STOP button is pressed. The light above the STOP
switch will be lit.
The red light above the TEST switch indicates when valid timecode is being received.

CCF Audio Track Construction:
Please refer to diagrams CCF audio track construction (method 1) and CCF audio track
construction (method 2) on the following two pages.
Method 2 is recommended because easiest to implement and when an inter-loop is
required, the "same audio chunks" need only be 35 mS long. The only drawback when
using method 2, is that the parade float audio will start playing two seconds after the
façade audio starts. They will, of course, be in sync when the parade float audio does
start playing. This delay only happens when the CCF first starts. All subsequent loops
play properly, as expected. If this is not a problem for your attraction, then this method
is recommended. Otherwise, use the method 1 procedure.
DTMF packets come in groups of six DTMF tones. The "Loop-Point" should not occur
within a DTMF packet. If the "Loop-Point" does lie within a DTMF packet, the entire
DTMF packet should be muted. Muting one or more consecutive DTMF packets is not
a problem.
The DTMF timecode track is now created using a Windows utility program called
"DTMFgen.exe". The following three files must be in your path and reside in the same
directory (e.g., C:\util or C:\HQ): DTMFgenV20.exe, dtmf36.bin, dtmf44.bin.
You may create a shortcut for "DTMFgenV20.exe" to your desktop if you like. This
utility can be found at our website http://www.jrsky.com/utilities.html
Click on utilities.zip to download the files.
To run the program:
1) Click on the "DTMFgenV20.exe" icon.
2) Select either DTMF-F (default) or DTMF-S
3) Select the method, either Method 2 (default) or Method 1. See the following text for
details.
4) Now enter the "Sample Length". This is the total number of samples as in the master
audio track, assuming the master audio track is edited to loop perfectly at the end.
5) Now click on "Generate".
The created DTMF timecode file, "tc.wav", will appear in the same directory where the
"DTMFgenV20.exe" resides. If you have just one main loop, nothing else is required. If
you have an inner loop, then you will have to add a Loop-Point using the
"WaveLoop.exe" Window utility program. If you required an inner loop and if you are
using Method 2, then you will need to change one of the DTMF tones to an '*' tone. See
the diagram on page 23 for details.
The DTMF track must go in the Channel 1 position of the CCF player. If an inter-loop is
required, the DTMF track also must have the "Loop-Point" applied to the DTMF.wav
track. Only one "Loop-Point" is necessary for the inner-loop point as the audio will
automatically loop at the end of the audio track. Fifty milliseconds of silence should be
added to the end of audio on channels 2-16. Channels 2-16 should not have a LoopPoints applied to them.

NOTE: If you are uncertain or uncomfortable in creating the DTMF timecode track, we
will be happy to make it for you. All we need to know is if you want to use Method 1 or
Method 2, and where the "Loop-Point" should be placed if required. You would still be
responsible for the façade and float audio tracks.
Card Settings for CCF unit:
C992 Controller Card settings:
Shunt for W1 in the O position.
C990 or C993 Audio Card settings:
Shunt for W1 in the OUT position.
Shunt for W2 in the EXT position.
Shunt for W3 in the O position (C993 only).
The RS232 settings are:
9600N81, no hardware control, no software control.
The RS232 commands are:
Enter a number 1-99 then 'p' or 'P' to select file to Play.
Enter a number 1-99 then 'x' or 'X' to select neXt file to play.
's' or 'S' to Stop (default at power up).
'e' or 'E' to Enable LoopMark (default at power up).
'd' or 'D' to Disable LoopMark.
'n' or 'N' to select NORMAL mode.
'H' to set ecHo on (default).
'h' to set echo off.
Notes:
1) The CCF unit must be in the NORM mode to receive RS232 commands.
2) When using the new RS232 rev C firmware, the system will also lock to SMPTE
30FND if present at the timecode input.

Parade Float Audio Track Construction:
All the float audio players that follow the transmitted CCF DTMF timecode will have a
35mS delay with respect to the CCF façade audio. There are two ways to correct this;
either add an external audio delay unit to all the CCF audio channels or advance the
float audio tracks. The first solution requires additional hardware and adds extra cost to
the parade system. The second solution does not require additional hardware or cost
and therefore is the recommended solution.
Please refer to the diagram "Parade float audio track construction".
Modify the audio track as shown in the diagram. If you are using an external audio
delay for the CCF façade audio, then do not cut and paste the audio chunk as shown in
the diagram.
"Loop-Point" should not be applied to any of the parade playback unit tracks. However
the channel 1 audio track must have the exact total number of samples as the DTMF
track in the CCF unit. All the other audio tracks in the parade playback units must have
the exact same or greater number of samples as the DTMF track. Fifty milliseconds of
silence should be added to the end of audio on channels 2-5.
The DTMF signal applied to the Type 3 and 4 units should not exceed 2 volts peak to
peak at the input.
C992 Controller Card settings:
Shunt for W1 in the O position.
C990 Audio Cards settings:
Shunt for W1 in the OUT position.
Shunt for W2 in the EXT position.

What Compact Flash Memories to Purchase
Not all Compact Flash memories are the same. Only high performance Type I Compact
Flash memories that use SLC technology will work in this application. Compact Flash
using TLC or MLC, will not work. On some memories, we have found the Compact
Flash "Command to DRQ" time to exceed 2 mS. These modules will not work for
Nuoptix applications. The "Command to DRQ" time is related to the controller used
inside the Compact Flash. We would recommend purchasing all Compact Flash
memory modules directly from Nuoptix as we qualify all the modules that we sell. All
Lexar Compact Flash work at the time of the printing.
Formatting the Compact Flash
The Compact Flash (CF) must be formatted every time prior to copying a Nuoptix audio
file to the CF module. You cannot simply delete a Nuoptix audio file and copy another
to the CF memory.
Windows2000 & XP method to format the Compact Flash media.
1) From the Windows Desktop double left click on "My Computer".
2) Single right click on the appropriate "Removable Disk" for your Compact Flash
adapter.
3) Single left click on "format…".
4) Select "Quick" for the "Format type" option.
5) Select "FAT, FAT16 or FAT32 (NTFS & exFAT will not work) for "File System".
6) You will get a dialog box warning you that all data on the removable disk will be
erased. Click "OK" to the warning.
7) After formatting is complete, click "OK" and "Close".

Copying a file to the Compact Flash
Copy the audio wave file to the Compact Flash as you would any other file. Long file
names are now acceptable. Wait for the Compact Flash activity light to stop blinking
before removing the media. If you are running Windows 2000 or XP, you must first
eject the drive before you remove the media. Failure to do this will result in audio data
corruption. (This may not apply to all Compact Flash adapters. Read manufacturer's
guidelines.)
Note: The above procedure applies only to the C990 & C993 boards that have a label
marked as "C990 rev G or C993 rev C " or higher on the U5 micro-controller chip. If this
chip has a different label marking or no label, then only "short file names" can be used
(i.e., 8.3 filenames, eight characters or less plus the .wav extension) and these must be
formatted with FAT16 only. Upgrade chips are available for $10/each.
