CUSTOM INSTALLATION (C.I.) USE

The 540A V2.0 and 640A V2.0 feature 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.

In addition the units feature '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 teaching into C.I. systems as follows:

1.Press and hold the Standby button. The remote first generates it's standby (toggle) command. Keep the button held down, after 12 seconds an amplifier “On” command will be generated. If the button is kept held down for a further 12 seconds, an amplifier player “Off” command is generated.

2.Press and hold the Mute button. The remote first 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.
