the signal entering the mixing amplifier is weak, but even so it contains a background
noise, so the signal/noise ratio is low (low signal). When the output amplifier equally
amplifies both parts as a whole, the output has a very high background noise. In the
second case, as the channel VOL control is set to the maximum, the signal received by
the mixing amplifier has a high level and therefore also a high (good) signal/noise ratio,
so when this signal reaches the output VOL control and is amplified, the signal/noise
ratio remains better than in the previous case.
CLEANING
The front panel should not be cleaned with dissolvent or abrasive substances because
silk-printing could be damaged. To clean it, use a soft cloth slightly wet with water and
neutral liquid soap; dry it with a clean cloth. Be careful that water never gets into the unit
through the holes of the front panel.
