Check the following

Check the headphones have not connected to another device like a phone or tablet before the

amplifier could connect to them.

If your headphones have a power saving auto mute function when removed from the head (head

detection), they may need to be unmuted to restore sound when refitted.

Is the amplifier correctly plugged in and switched on?

Is the audio source correctly connected, with the correct input selected?

Is the amplifier muted?

Is the amplifier in protection mode (as described below)?

The amplifier may enter a protection mode. The front panel display indicates the fault type:

FAULT DC OFFSET: The amplifier detected an overload. Power off and reduce the volume

•

after turning back on.

FAULT SHORT (CIRCUIT): The amplifier detected a speaker short circuit. Inspect all the

•

speaker cables to make sure none of them are shorted together. This fault is more common

when exposed wires are being used to make speaker connections.

FAULT OVER TEMP: The internal temperature of the unit reached an unsafe level. Allow the

•

amplifier to cool.

In protection mode, the amplifier will turn itself off and power to the speakers will be removed. To

continue using the amplifier, the fault must be treated, and the amplifier must be turned OFF then

back ON from the power switch on the rear panel.

Are there fresh batteries in the remote control?

Are you pointing the remote control towards the amplifier window without obstruction?

Is the amplifier correctly plugged in and switched on?

Is the amplifier in standby?

Is the display dimmed to "Off"?

Press the

button on the remote control.

Ensure all cables are making a good connection.

Try disconnecting the input cable and plug it fully in again (turn the power off before doing this).

If the Hum stops when the source is disconnected, the problem is most likely to be in the cable or the

source device to which it is connected.
