2 Basic operation

2.1 First operation / self test

In case the C 5.2 was not connected to mains a self test will be performed when it is switched on by
the mains switch (29) for the first time. The unit will check its configuration and that all the installed
components work properly. The procedure is shown in the display. Afterwards the unit will switch to
stand-by.

2.2 Switching on / stand-by

Using the button power (1) you can switch between on (operate) and stand-by. In the on state the
display (10) lights up and the LED (3) is off. In stand-by mode the display is off and the LED is on to
indicate that the unit is still connected to mains.
CAUTION: When switched to stand-by the unit is still connected to the mains. In case of a
thunderstorm or if you leave the house for a longer time we recommend that you switch the amplifier
off by using the mains switch (29) or pull the mains plug.

2.3 Selecting the signal source

The signal source can be selected by turning the source selector (2) until the desired source appears
on the display.
CAUTION: If you switch to another source while playing a CD, the drive will stop first. This may take a
few seconds. If you activate a digital input that has no valid signal, "NO DIG SIGNAL" is indicated in
the display (10). In this case the source can not be changed.

2.4 Volume setting

Use the rotary encoder (11) to set the desired volume. Depending on rotating speed the volume
increases / decreases in 0.5 dB steps (slow) or 2 dB steps (fast). The actual setting is shown in the
display (10). If the volume is changed using the RC 3 remote control, the level always increases /
decreases in 0.5 dB steps.

2.4.1 Setting of input sensitivity

The level of signal sources differs often by several dBs. You recognize a step in volume, when
switching between two different 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 (except for tuner or CD) and chose a convenient volume level. Now press the MENU
button (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.
