2. Basic operation
2.1 POWER button
In
permament
mode the unit is switched on and off by pres-
sing the POWER button (1). In other operating modes (see
section 2.6 Operating modes), the power stage is switched on
and off from an external source. The POWER button is ineffec-
tive in these operating modes, which is indicated on the dis-
play when pressed.
After switching on, the power amplifier needs a short amount
of time to warm up the tube section. The message
tube
warmup
appears in the display. Please wait until the entire
waiting for tube warmup
display changes completely from
lower case to upper case characters. The two analog transfor-
mers for the power amplifiers are then switched on and, after
checking that there are no errors, the protective relay is relea-
sed (a sequence of clicks can be heard from the device). The
MA 8.3 / SA 8.3 is now ready for operation.
2.2 DISPLAY button
If you wish to switch off the display while listening to music,
you may deactivate it by pressing the DISPLAY button (5).
