Cambridge Audio 540A - Manual (Page 10)

10 Azur integrated amplifier
Standby/On
Switches the unit between Standby mode (indicated by dim power LED)
and On (indicated by bright power LED). Standby is a low power mode
where the power consumption is less than 10 Watts. The unit should be
left in Standby mode when not in use.
Infrared sensor
Receives IR commands from the supplied Azur remote control.
Phones
Allows for the connection of headphones with a ¼" Jack plug connector.
When the headphones are connected, the loudspeaker relay is released
switching off the output to the loudspeakers (speakers A and B).
Protection
LED flashes to indicate activation of CAP5 protection system. Refer to
the CAP5 section of this manual for more information.
Speaker B
Turns on/off the secondary set of loudspeaker terminals on the back
panel. This can be used for listening to an extra set of loudspeakers in
another room.
Please note that care should be taken when selecting if two loudspeakers
are going to be used on each channel. If the combined resistance
measured on the loudspeaker terminals is too low the amplifier may not
switch out of Standby mode until a suitable load resistance is detected.
For more information refer to the CAP5 section of this manual.
Note: When using two pairs of speakers, use speakers with a nominal
impedance of between 6-8 ohms each.
