There are four programmable-link jumpers J1-J4 and two hard-wired links J5 and J6.
J
1 Remote Fader In/Out:
IN enables fader transfer.
OUT disables the transfer of faders.
J2 NS Surr Off/On:
OFF disables surround channels in Non-sync.
ON enables surround channels in Non-sync.
J3 Wake-Up Local/Remote:
LOCAL ensures that the local fader is selected at power on. REMOTE selects remote faders at power
on.
J4 Wake-Up Format / Non-Sync Processing:
The top 8 positions choose which format will be selected at power-up:
Wake-Up Jumper Position Format Description
01 Mono
04 Dolby Stereo A-Type
05 Dolby Stereo SR
NS 2:4 Non-sync 2:4 matrix decode
SR•D (10) Dolby Digital
42 Dolby Stereo 70mm
60 Non-sync
22 35mm mag with surround
The lower two positions determine the processing on the non-sync signal when the front panel non-
sync button is pressed:
Non-Sync Mode Jumper Position Description
Std Selects standard Non-sync processing. The non-sync signals are sent directly to the left
and right screen channels without matrix decoding to maximize stereo width. The
optional surround channel is derived via the Cat. No. 150 and selected by J2 with level
adjusted on the Cat. No. 441. There is no center or subwoofer output.
2:4 Selects a full 2:4 matrix decode of the non-sync signal. The output is sent to the left,
center, right, surround and subwoofer channels without noise reduction. This format
could be used in dubbing stages and screening rooms for playback of video and music
sources.
J5 Inhibit Cat. No. 384 Output:
JUMPER INSTALLED: Diodes inserted in the spare logic line column (SPR) at the various format
positions will disable a Cat. No. 384 edgecode reader when that format is selected and override any
codes on the film.
JUMPER NOT INSTALLED: diodes fitted in the spare (SPR) column have no effect on the edgecode
reader.
J6 Mute Wake-Up State Live/Mute: LIVE sets the fader to the unmuted state at power-up. MUTE sets
the fader to the muted state at power-up.
Note: If J1 is out and J3 is
remote, fader cannot
be called back to local.
