Mains Voltage Selector Switch 115V/220-230V AC ~ 50/60Hz

Rear panel connections

Audio inputs

These inputs are suitable for any ‘line level’ source equipment such as the
audio outputs of CD players, BD/DVD players, etc.

Phono input

This input has a built in phono stage. Record players fitted with Phono
Cartridges of the Moving Magnet (MM) or h

high  output Moving Coil (MC)

type (between 2-6mV output and 30-50k load impedance) can be used.
Low output Moving Coil types (<1mV and usually 10-1000 ohm load
impedance) cannot be directly connected and will require a matching
transformer or head amp. Please consult your dealer for details. 

Note: The ‘Ground’ terminals on both the record player and the AM10
should be connected (where possible) with a ground wire for lowest
noise/hum pickup.

Rec Out

Connect to the recording input of a tape deck, CD recorder input, etc.

Loudspeaker terminals

Connect the wires from your left channel loudspeaker to the Left positive
and negative terminals, and the wires from the right channel loudspeaker
to the Right positive and negative terminals. In each case, the red terminal
is the positive output and the black terminal is the negative output.

Care should be taken to ensure no stray strands of wire are shorting
speaker outputs together. Please ensure that the loudspeaker terminals
have been tightened adequately to provide a good electrical connection.
It is possible for the sound quality to be affected if the screw terminals are
loose.

Voltage select switch

For servicing use only.

AC power socket

Once all connections are complete, plug the AC power cable into an
appropriate mains socket and turn the unit on.
