Power
Plug the power supply lead into the socket (10) on the rear of the amplifier. Connect the mains
lead to the power supply and then plug into a mains outlet. Switch on the power at the outlet.
This amplifier may also be used with DC power supplies directly connected to the amplifier
such as those found in buses and coaches.

Operation

When connecting power for the first time to your amplifier the power button (8) will illuminate
blue and the amplifier will be "On". This is normal operation and is useful where remote
switching of the system is required such as in buses and coaches.
Pressing the power button will change the colour to red and the amplifier will be in the stand-
by mode which uses low power and no signal will be passed to the loop. In order to remove
all power from the unit the power supply must be disconnected from the amplifier and the
mains outlet.
Press the button power again and it will light up blue. The system is now ready for use.
• Set the television or other audio equipment to the normal listening level for other
members of your household.

Pressing the power button will turn the amplifier off and the light will go red. The next time
the power is turned on the volume, tone and source selections from the previous session will
