Operation
Power
The power switch on the rear panel switches the amplifier on or off. When you have finished making
connections, switch the amplifier on.
Standby
The Standby button on the front panel switches the amplifier between standby and on (operating).
Auto Standby
By default, this amplifier is set to enter standby automatically after 20 minutes with no audio playing and no
user interaction. This is to meet international power consumption regulations. This can be changed in the
menu. To use the menu, see Page 13.
Selecting Inputs
Audio sources can be selected either using the INPUT selector on the front panel or using the remote
control. In each case, the source name corresponds to the labelled input sockets.
The Inputs are:
BT (Bluetooth)
Phono (analog – turntable with moving magnet cartridge)
AUX (analog – front input)
CD (analog)
PVR (analog)

Note: The digital inputs only support stereo (PCM) audio. Multichannel audio or encoded
audio of any type is not supported.
Phono Input
The Phono Input includes a pre-amplifier to work with a MM (moving magnet) cartridge on a turntable for
playing vinyl.
NEVER connect anything other than a turntable through this input. This can result in
serious damage to both your amplifier and speakers and will not be covered under
warranty.
USB
The USB socket on this amplifier is only intended for software updates. It is not an audio input.
