The preamplifier is switched on and off using this button at the front panel.
It has no standby option. When switched off the device is internally separa-
ted from the AC power. As a precaution, after switching on, the volume set-

ting of the preamplifier should be reduced. After switching on, the device
needs a few seconds before it is ready to operate. Meanwhile, the LED in
the speaker's knob (3) will be blinking. During power-on mode, one of the
LED for the input selection (2) will be lighted.
At the front panel: If you turn the dial "INPUT", you select one of the devi-
ces connected to the inputs on the back of the SA-31MK (11) for playback.

The LED associated to the selected input channel will be illuminated at the front
of the appliance. Before switching over the input channel, the volume (3)(18)

At the front panel: Turn the knob "VOLUME" clockwise to turn up the
volume and counter-clockwise to turn it down.

If the sound is not to be changed, it is recommended that you switch off the
sound control (BASS, TREBLE) with this button on the front of the device.

trollers (9)(10) come into play. If the button is not pressed, the two sound
controllers in the preamplifier are bypassed and the signals from the source
are not changed in terms of their frequency levels.
This function is operated from the front panel. It is a feature of audio ampli-
fiers that permits the user to strengthen low and high frequencies compared
