Operation - IMG STAGELINE PAK-410 Bedienungsanleitung

of "img Stage Line"). For additional mount-
ing options, e. g. suspension, five M10
threaded jacks are provided (2 on the upper
side, 2 on the lower side, 1 on the rear). If
you use these jacks, unscrew the plastic
cover caps.
When setting up the speaker system,
always make sure that air will be able to
flow freely through the cooling fins on the
rear; otherwise, problems may occur due to
overheating of the amplifier and the protec-
tive circuit will mute the sound.
4.2 Connection
Before making or changing any existing
connections, switch off the speaker system
and the units to be connected.
1) Feed the audio input signal via an XLR
plug or 6.3 mm plug to the jack INPUT
(7). This jack allows to connect the line
level output, e. g. of a mixer, CD / MP3
player or preamplifier. When connecting
a line level output, make sure that the
button LINE / MIC (5) is disengaged.
Alternatively, connect a microphone
to this jack. In this case, engage the but-
ton LINE / MIC.
2) If another active speaker system is
required for sound applications in larger
zones, connect the line level input of this
speaker system to the XLR output
THRU (6). The input signal of the jack
INPUT is present at his output.
3) For power supply, use the mains cable
provided to connect the mains jack (12)
to a mains socket (230 V~ / 50 Hz).

5 Operation

1) To prevent the initial volume from being
too high, set the control LEVEL (4) to
MIN before switching on. Then switch
on the speaker system with the POWER
switch (11). Switch the front LED on or
off as desired using the corresponding
button (3).
2) Engage the button GND LIFT (6) for
testing: If there is no music signal and an
annoying hum can be heard, this hum
may be due to a ground loop. In this
case, disengage the button.
Ground loops may occur when two
units are connected both via their signal
ground and via the ground conductor of
the power supply or a conductive con-
nection of the housings. In case of a
hum, test both positions of the button
GND LIFT.
3) Use the control LEVEL to adjust the
desired volume.
CAUTION Never adjust a very high
accustomed to high volumes which do
not seem to be that high after some
time. Therefore, do not further increase
a high volume after getting used to it.
