No guarantee claims for the unit and no liability for any
resulting personal damage or material damage will be
accepted if the unit is used for other purposes than origi-
nally intended, if it is not correctly operated or not
repaired in an expert way.
If the unit is to be put out of operation definitively,
take it to a local recycling plant for a disposal which
is not harmful to the environment.
3 Power Supply
The power supply can be made with a 9 V battery or a 9 V
power supply unit (e. g. PSS-906DC from MONACOR).
1) For battery operation, unscrew the battery compartment
at the lower side of the unit and insert a battery (not sup-
plied).
2) For operation with a power supply unit connect the power
supply unit to the jack 9 V
inserted, it is switched off. A low voltage plug 5.5 / 2.1 mm
(outside / inside diameter) is required. Always observe
the correct polarity: The positive pole must be at the cen-
tre contact!

Attention! Remove the battery if the unit is not in use for a
longer time or if it is only operated with a power supply unit.
Thus, the unit will not be damaged in case the battery
should leak.
Do not put exhausted batteries into the household
rubbish but take them to a special waste disposal
(e. g. collective container at your retailer).
4 Operation
1) Connect the microphones to the jacks INPUT 1 to 4 (1).
2) Connect the jack OUTPUT (2) to a line input of the fol-
lowing unit (amplifier, mixer, recorder).
3) Set the controls MIC 1 – 4 (4) of the channels to which no
unit has been connected to "0". Set the other controls to
mid-position first.
4) To switch on the unit, turn the control MASTER (5) clock-
wise. The LED ON PK (6) shortly lights up at maximum
brightness first and then keeps lighting at lower bright-
ness.
5) Adjust the output level with the control MASTER so that
the following unit is adjusted to an optimum level.
6) Mix the microphone signals with the controls MIC 1 – 4 or
fade them in and out. The LED ON PK serves as a level
indicator.
