AC power socket

Once you have completed all connections to the amplifier, plug the AC Power Cable into an appropriate mains socket. The amplifier is now ready for use.

Loudspeaker connections

The 540A and 640A have two sets of Loudspeaker terminals on the rear panel, speakers A and B. Speakers A are the main speaker terminals, speakers B are the secondary switchable speaker terminals. Connect the wires from your left channel loudspeaker to the LEFT + & - terminals, and likewise the wires from the right channel loudspeaker to the RIGHT

+& - terminals. In each case the red terminal is the positive output, and the black terminal is the negative input. Care should be taken to ensure no stray strands of wire are shorting speaker outputs together. Please

Note: This amplifier has been designed for use with loudspeakers that have a nominal impedance of between 4 and 8 ohms.

Please ensure that the speaker 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.

Pre amp outs

Connect these sockets to the inputs on an external Power Amplifier(s).

Tape mon

These sockets can be connected to a tape deck or to the analog sockets on a MiniDisc or CD recorder. Connect an interconnect cable from the recorder's Line Out sockets to the amplifier's Tape Monitor sockets. This
