1 MAINS SWITCH (POWER)

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

AINS CONNECTOR (MAINS IN)

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 (LINE 1/INPUT)

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 (LINK OUTPUT)

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

IMIT INDICATOR (LIMIT)

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

OLUME LEVEL CONTROL (VOLUME)

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

OLARITY SWITCH (PHASE)

Select 0° if the signal polarity should not be

inverted. Select 180° to change the signal

polarity by 180°.

8 I

NPUT CONNECTOR FOR AUDIO SIGNAL (INPUT 2) WITH SENSI-

TIVY SELECTION SWITCH (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

possible, balanced signal feed is al-

ways preferable to guard against potential noise or HF-in-

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-

press the switch to MIC mode.

CAUTION: Do not plug a line level signal into INPUT 2

when MIC/LINE 2 is in the MIC position.

HINT: There is no phantom power available at the

INPUT 2 connector, so powering a condenser

microphone is not possible.

9 AUX

CONNECTOR FOR AUDIO SIGNAL (AUX L/R)

Stereo unbalanced RCA inputs AUX L/R

for connecting sources such as CD play-

ers or MP3 players. Both RCA inputs are

summed and can be controlled with IN-

PUT 1 LEVEL. The inputs can be used simultaneously with

the XLR/TRS LINE 1 connector.

10 S

IGNAL SOURCE SELECTION SWITCH (SELECT)

Use the SELECT switch for selecting the out-

put signal of the LINK OUTPUT connector.

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.
