For more information on pairing refer to your Apple device’s instruction manual.

Pairing – To pair with an Apple device, press and hold the required source button along with the ￿ button for six seconds. Some devices like Apple TV have visual indication once pairing is achieved.

Un-pairing– To un-pair an Apple device, press and hold any of the source buttons along with the ￿ button for six seconds.

Custom installation (C.I.) use

The 550A and 650A 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 its standby (toggle) command. Keep holding the button down and after 12 seconds an amplifier “On” command will be generated. If the button is held down for a further 12 seconds, an amplifier “Off” command is generated.

2.Press and hold the Mute button. The remote first generates its mute (toggle) command. Keep holding the button down and after 12 seconds a “Mute On” command will be generated. If the button is held down for a further 12 seconds, a “Mute Off” command is generated.
