There are four programmable-link jumpers J1-J4 and two hard-wired links J5 and J6.

J1 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:

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.
