Direct
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.
Bass
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.
Volume
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.
Balance
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.
Aux,
CD,
Tuner/DAB,
DVD,
AV/MD
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).
Tape
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.
