Technical specications

The 851E features a Control Bus input/output that

allow un-modulated remote control commands

(positive logic, TTL level) to be received electrically

by the unit and looped to another unit if desired.

These control commands are typically generated

by custom installation (multi-room) systems or

remote IR receiver systems. The Control Bus sockets are colour-coded

orange.

An IR Emitter Input is also provided that allows modulated IR remote

control commands to be received electrically by the unit. Commands on

this input operate the unit only and are not looped out demodulated on

the Control Bus Output.

An RS232C port is also featured which allows the 851E to be

controlled by C.I. systems.

In addition the unit features 'direct' IR/Control codes as well as toggle

codes for some of their features to simplify programming custom

installation systems. Special direct On/Off and Mute commands can be

accessed on the supplied remote control for coding into C.I. systems as

follows:

1. Press and hold the Standby/On button. The remote rst generates

its standby (toggle) command. Keep the button held down, after 12

seconds an amplier "On" command will be generated. If the button

is kept held down for a further 12 seconds, an "Off" command is

generated.

2. Press and hold the Mute button. The remote rst generates it's mute

(toggle) command. Keep the button held down, after 12 seconds a

"Mute on" command will be generated. If the button is kept held down

for a further 12 seconds, a "Mute off" command is generated.
