Intr oduction The graphic equaliser is a vital component in any audio system. The entire signal passes through it and so any limitations imposed by the equaliser will compromise the performance of the whole system.
DN360 Graphic Equaliser The Klark T eknik DN360 is a dual channel, 30 band equaliser of fering 12dB of cut or boost in 1/3 octave steps between the frequencies of 25Hz and 20 kHz.
The nature, shape and way in which individual equaliser filters combine, has a profound effect on the control provided by the equaliser and on the resulting quality of sound.
Front Panel Functions The power switch is a two pole type, isolating both the live and neutral conductors. When the power is on, a red status LED lights. The input level control allows the system gain to be up to+6dB when in its fully clockwise position, and offers full attenuation in its anti-clockwise position.

The Use of Graphic Equalisers Equalisers may be used for corrective or creative purposes and the Klark T eknik DN360 is applicable in both live sound and studio applications.
In live sound applications, graphic equalisation is almost always applied separately to the stage monitor of foldback system to reduce the level of those frequencies that would otherwise cause feedback problems.

Equalising a Sound System When equalising a sound system you should always remember just what it is you are trying to achieve. T wo fundamental reasons for equalization are:- 1. T o increase the potential gain or power output of the system before feedback.
A good idea is to rotate the measuring microphone in a wide arc or circle round the measuring position and to see if any strong interactions occur causing large deviations in response. If necessary , move to another position. Also ensure that the ambient noise level is at least 6dB (preferably 10dB) below the signal level you are using.
Inserting the Equaliser in the Signal Chain The exact point of insertion of an equaliser into the signal chain will very much depend on the task in hand e.g. mixer channel / line input, group insert point, group output, auxiliary send or between another signal processing device and the mixer or power amplifier , etc.
Important Note: It is often useful to call your dealer or the factory explaining the nature of the problem with the unit. In many instances the problem can be solved without returning the unit to the factory . If the unit has to be returned to the factory , use original packing only .
