Attention - Klark Teknik DN370 Operator's Manual

The following special limitations must be observed in order to maintain safety and electromagnetic compatibility
performance.
Power Connection
The DN370 Graphic Equaliser should only be operated with the
power supply connected to ground via the ground in the mains
connector.
Audio Connections
The DN370 should only be operated with high quality twisted-
pair audio cables. XLR connector shells should be of metal
construction so that they provide a screen when connected to
the console and should have pin one (1) connected to the cable
screen.
INSTALLATION
Position
The DN370 should be mounted in a nineteen inch (19") rack of suitable construction for it's intended purpose. Four (4) rack
mount holes are provided through the front panel to support fully, the weight of the unit in the rack. Position of the unit will
depend upon how it is to be used however:-
- Avoid placing the unit such that the faders may be accidentally knocked or snapped off
- Avoid placing the unit such that the front mounted power switch may be accidentally knocked
Also try to avoid placing the unit directly near or on any power distribution units or power amplifiers.
Power
The internal power supply is a switch mode type which automatically senses the incoming mains voltage and will work where the
nominal voltage is in the range 100-240 VAC. A single fused IEC mains inlet is provided on the rear panel and the correct lead for
connection in the area to which the unit was shipped is provided in the box.
Connections
To ensure the correct and reliable operation or your DN370 Graphic Equaliser, only high quality balanced screened twisted pair
audio cable should be used.

Please inspect the unit carefully for any signs of damage that may have occurred in transit and notify the courier immediately if
you feel that any damage has occurred.
Electric Fields
If the DN370 is operated in an electromagnetic field that is
amplitude modulated by an audio frequency signal, the signal
to noise ratio may be degraded. Degradation of up to 60dB
may be experienced under extreme conditions (3V/m, 90%
modulation).
