540A/640A V2.0 Integrated amplifier

6Direct

This control gives the audio signal a more direct path to the power amplifier stage of your amplifier, bypassing the tone control circuits for the purest possible sound quality.

7Bass and Treble

These controls allow subtle adjustments to the tonal balance of the sound. In the central position these controls have no effect. These controls only modify the sound through your loudspeakers and the Pre- Out sockets, they do not affect the signals sent through the Tape Out connections. With a well produced CD and a good system the tone controls are unnecessary and can be switched out by the Direct switch. If the musical recording is of poor quality or other factors are affecting the sound quality, it may be necessary to adjust the tone controls to compensate.

8Volume

Use to increase/decrease the level of the sound from the outputs of the amplifier. This control affects the level of the loudspeaker output, the pre-amp output and the headphone output. It does not affect the Tape Out connections. It is advisable to turn the Volume control fully anti- clockwise before switching the amplifier on.

9Balance

This control allows you to adjust the relative output levels of the left and right channels. In the central position the output from each channel is equal. This control only modifies the sound through your loudspeakers and the Pre-Out sockets, it does not affect the signals sent through the Tape Out connections.

10Aux, CD, Tuner/DAB, DVD, DMP/MP3

Push the appropriate input selection button to select the source component that you wish to listen to. The signal selected is also fed to the Tape Out sockets so that it may be recorded. The input should not be changed whilst recording (but the recorded signal can be checked using the tape input Tape Monitor).

11Tape Monitor

This control lets you listen to the output signal from a tape recorder or signal processor connected to the amplifier's Tape In/Rec Out sockets. When Tape Monitor is selected, the source component chosen by the input selection push buttons continues to be routed to the Rec Out sockets for recording or processing.
