1Power On/Off

Switches the unit on and off.

2Mains voltage selector switch

Switches the mains voltage between 115V and 230V. For use by installer/dealer only.

3AC power socket

Once you have completed all connections to the amplifier, plug the AC power cable into an appropriate mains socket. Your amplifier is now ready for use.

4Loudspeaker terminals

Two sets of loudspeaker terminals are available, A (main loudspeaker terminals) and B (secondary switchable loudspeaker terminals).

6Azur integrated amplifier

Connect the wires from your left channel loudspeaker to the LEFT + & - terminals, and the wires from the right channel loudspeaker to the RIGHT + & - terminals. In each case, the red terminal is the positive output and the black terminal is the negative output.

Care should be taken to ensure no stray strands of wire are shorting speaker outputs together. Please ensure that the loudspeaker terminals have been tightened adequately to provide a good electrical connection. It is possible for the sound quality to be affected if the screw terminals are loose.

Note: When using one pair of speakers, use speakers with a nominal impedance of between 4-8 ohms. When using two pairs of speakers, use speakers with a nominal impedance of between 6-8 ohms each.

5IR (Infrared) Emitter In

Allows modulated IR commands from multi-room systems to be received by the amplifier. Commands received here are not looped out of the Control Bus. Refer to the ‘Custom Installation’ section for more information.
