Button(s) Description
VOLUME
Turn the knob "VOLUME" clockwise to turn up the volume and
(4)
counter-clockwise to turn it down. The volume setting does not
influence the signal at the output "AUDIO OUTPUT" (9).
TREBLE (5)
With the "TREBLE" control dial on the front of the device you affect
the proportion of higher frequencies in the sound. Turning it in
clockwise direction increases the treble intensity and moving it in
anticlockwise direction reduces it. In the middle setting the treble
proportions of the input signals remain unchanged. This tone con-
trol affects the loudspeaker signals, the signal of the output "AUDIO
OUTPUT" (9) is independent of this.
