Top Products
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. The majority of applications within the sound
reinforcement, broadcast and recording fields, require a smooth and continuous equalisation response curve in
order to correctly contour the overall response characteristics of a sound system, loudspeaker, recording effect
or audio channel. To achieve this, the individual filters must be capable of combining smoothly together to
result in a continuous response curve, free from shape discontinuities in orders to avoid unwanted audible peaks
or anomalies in the final sound.

Other features include an overload LED per channel, which warns of impending overload at any point in the
equaliser. A signal-ground lift switch and an optional security cover to prevent unauthorised personnel from
tampering with the control settings.
This product is built to the same high electrical and mechanical standards as all Klark Teknik equipment and is
both robust and stylish. It occupies a standard three units of rack space and has transformer balanced inputs
and outputs.
Even the advanced technology incorporated in this product, each instrument is given the full backing of
Klark Teknik's " " which proves each product against a specification consistent with the
highest professional standards. Only top quality components are used, and every unit is bench tested and aligned
before a burn-in period and final performance test.

reliability control
In order to offer operational flexibility a variable fader resolution has been
incorporated i.e. 6 or 12 dB cut or boost. This function ("scale") is combined
with the bypass switch, which silently removes the graphic equaliser section from
the signal path. A subsonic 18dB/octave roll off filter (-3dB @ 3Hz) can be
switched in or out from each of the channels.
