Cambridge Audio 840A - Manual (Page 6)

6 Azur Class XD integrated amplifier
Power On/Off
Switches the unit on and off.
AC power socket
Once you have completed all connections to the amplifier, plug the AC
power cable into an appropriate mains socket then switch on. Your
amplifier is now ready for use.
Loudspeaker terminals
Two sets of loudspeaker terminals are available, A (main loudspeaker
terminals) and B (secondary loudspeaker terminals). Both sets of
speakers can be turned on and off. 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 short the speaker
outputs together. Please ensure that the loudspeaker terminals have been
tightened completely 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.
IR (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.
Control Bus
In - Allows un-modulated commands from multi-rooms systems or other
components to be received by the unit.
Out - Loop out for control bus commands to another unit. Also allows the
840A to control some Cambridge Audio units.
