INSTALLATION & OPERATION
DIGITAL TIME DELAY CARD:
MOD5x325
The digital time delay portion of the MODIIC system
is contained on this card. The surround channel pass-
es through the time delay whenever any Stereo-
Optical format is selected by the operator. Music or
digital inputs are NOT time delayed. There is a rotary
switch on this card that is used to set the time delay
setting. The rotary switch has 16 positions: 0-9 & A-F.
Position 0 is 10 milliseconds of delay, which is the
minimum delay setting. Each position clockwise adds
10 milliseconds of delay for a maximum setting of 160
milliseconds (position F).
OUTPUT/MUSIC CARD:
SRS5x330
Six channels of audio, (Left, Center, Right, Left
Surround, Right Surround and Sub), pass through the
MASTER VCA (Voltage Controlled Amplifiers) locat-
ed on the Output/Music Card. The digital inputs also
allow for separate Left Surround and Right Surround
channels in addition to a separate subwoofer input.
The VCAs exhibit very close tracking between chan-
nels and are controlled by the STEREO MASTER
FADER contained on the Format Card. Music Fade-in
and Fade-out, controlled by the automation or front
panel format switch, is also on the output card along
with a special music matrix to generate a four channel
non-sync sound from a standard two channel music
tape or CD player.
