1 M (POWER)
AINS SWITCH
Mains switch for switching the unit's pow-
er on or off. The switch lights after turning
the power on. If the switch does not light
when powered on with the mains cord
correctly connected and mains voltage
present, please contact your local dealer.
2 M (MAINS IN)
AINS CONNECTOR
The device receives its power sup-
ply via the MAINS IN connector.
Only the provided power cord may
be used. Connect the device only
to a mains network, which corre-
sponds to the requirements indi-
cated on the type plate.
3 I
NPUT CONNECTOR FOR AUDIO SIGNAL
Electronically balanced input for the con-
nection of a line level signal source, such as
mixer, signal processor, etc. Establishing a
connection is possible via TRS or XLR-type
plugs. Whenever possible, balanced signal
feed is always preferable to guard against
potential noise or HF-interference.
4 O
UTPUT CONNECTOR FOR AUDIO SIGNAL
This output socket is for the connection of
an additional powered loudspeaker or sub-
woofer. The output signal is electronically
balanced with a maximum level of +18 dBu.
Output impedance is 150 ohms.
For the A 112A or A 115A, the output signal
is based on the selection made at the signal
source selection switch SELECT.
5 L (LIMIT)
IMIT INDICATOR
The LIMIT indicator signals the device is operating at
the internal power amp's limit. Frequent blinking of
the LED is acceptable, since the incorporated DSP
clip limiter prevents distortion. Continuous lighting indi-
cates that you have to be aware of degradation in the out-
putted sound. In that case, the input level has to be
reduced. The LIMIT LED also lights if the output level is re-
duced because of high amplifier temperature.
6 V (VOLUME)
OLUME LEVEL CONTROL
Level control for adjusting the volume of the
loudspeaker. The level control affects the
power amp's overall amplification. VOLUME
control does not affect the level of the LINK
OUTPUT connector.
7 P (PHASE)
OLARITY SWITCH
Select 0° if the signal polarity should not be
inverted. Select 180° to change the signal
polarity by 180°.

terference.
MIC/LINE 2 switch
Use the MIC/LINE 2 switch for switching between micro-
phone (+40 dB) or line (0 dB) input sensitivity. When de-
pressed, it activates a microphone preamp for use with
dynamic microphones. A pen or paperclip is needed to de-
(LINE 1/INPUT) press the switch to MIC mode.

LINE 1
LINE 1 allows the pre-fader signal from LINE 1 input to
pass to LINK OUTPUT (see illustration 2-1). The LINK OUT-
PUT signal level is not affected by the setting of the
INPUT 1 LEVEL control. The signal from AUX L/R is not
passed to LINK OUTPUT in this switch position.
(MIC/LINE 2)
Electronically balanced input for the
connection of a line level signal
source (such as mixer, signal proces-
sor, etc.) or a dynamic microphone.
Establishing a connection is possible
via TRS or XLR-type plugs. Whenever
