1. When you plug your amplifier into the mains the power indicator on the front
panel will glow red which means that the amplifier is in standby mode.
2. Press the power button beneath the power indicator and it will then glow green
indicating that the amplifier is ready for use.
3. Press the C (centre) button and the L/R (left/right) button for home cinema sound
or turn off the centre speaker if you are listening to a stereo audio source such as a
CD. There will be a delay of about 12 seconds before you hear the signal. This is
to allow the amplifier to stabilise.

1. If there is a major overload or short circuit the amplifier will shut down
automatically and the power indicator will fade and switch to red. The amplifier
should be immediately switched off at the mains.
2. When the fault has been rectified the amplifier can be switched on and will power
up as usual. You should wait at least two minutes before turning the amplifier on
again at the mains to allow the power supply protection circuitry to reset itself.
