3. Basic operation
3.1 First connection to mains
When the amplifier is connected to mains and switched on for the first time the it checks it’s configuration
and if all installed components work properly. The procedure is shown in the display. After that the unit will
switch to stand by.
3.2 Switching on / standby
Using the button power (1) you can switch between on (operate) and stand by. In the on state the display (4)
lights up and the LED (3) is off. In stand by mode the display (4) is off and the LED (3) is on to indicate that
the unit is still connected to mains.
CAUTION:
When switched to stand by the unit is still connected to mains. In case of thunderstorm or if you
leave the house for a longer time we recommend that you switch the amplifier off by using the mains switch
(16) or pull the mains plug.
3.3 Selecting the signal source
Use the program selector (2) to select a signal source. The selected source is indicated in the display (4).
3.4 Volume setting
Use the rotary encoder (10) to set the desired volume. Depending on rotating speed the volume increases /
decreases in 0,5 dB steps (slow) or 3 dB steps (fast). The actual setting is shown in the display (4).
3.4.1 Setting of input sensitivity
The level of signal sources differs often by several dBs. So you recognize a step in volume, when switching
between two inputs. With the sensitivity setting menu you can avoid this. The sensitivity of each input can be
adjusted between – 9.5 dB and + 10.0 dB.
Select any input and chose a convenient volume level. Now press the button MENU (7, under the display) for
more than 2 seconds. The button is now marked "EXIT LVL". Pressing this button again will exit the level
setting mode and bring the unit back to normal operating mode.
While level setting is active the display shows the actual level instead of the volume. Level can be set using
the volume knob (10). You can switch between the sources and adjust the levels.
After this is done press the "EXIT LVL" knob (7) and bring the unit back to normal operating mode. All level
settings are now stored.
NOTE:
While the level setting mode is active the unit will not respond to any remote control command.
3.4.2 Mute / unmute
Press the MUTE button (11) to mute the PA8. A second pressing performs the unmute function and the pre
amplifier continues to play music at the former level. Unmute will also be performed if the volume knob (10)
is rotated, or volume is set via the remote control.
