Custom installation (C.I.) use

The 550T 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.

In addition the unit features direct IR/Control codes as well as toggle codes for many of its features to simplify programming custom installation systems. Special direct commands can be accessed on the supplied remote control for teaching into C.I. systems as follows:

Specific power on/off commands – press and hold the Standby button. The remote first generates it's usual amp and tuner standby (toggle) commands (both are sent). Keep the button held down, after 12 seconds an Amp On command will be generated, then if the button is kept held down after a further 12 seconds an Amp off command is generated, then separated by 12 second pauses, Tuner On, and finally Tuner Off.

Specific band selection commands – press and hold the FM/AM key. The usual band toggle command is first, then the FM Mode command, followed by the AM Mode command is generated.

Specific Preset/Scan mode commands – Press and hold the Mode key. The usual mode toggle command is first, then the Scan Mode command, followed by the Preset Mode command.

Specific Mute On/Off commands – press and hold the Mute key. The usual mute toggle command is first, followed by the Mute On command, and then the Mute Off command.
