Introduction
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. For example, an
indifferently designed equaliser may introduce severe phase distortion, noise and other anomalies related to
centre frequency accuracy, filter shape and attenuation accuracy which may manifest themselves as an overall
deterioration in the perceived sound quality of the system. Clearly, this is an unacceptable state of affairs, but
fortunately your choice to utilise a Klark Teknik graphic equaliser will eliminate these problems, offering you
unprecedented product performance coupled with the highest filter calibration and reliability standards in
the industry.
For many years Klark Teknik has been at the forefront of equaliser design, and have carried our detailed research
into optimum filter response characteristics, including their sonic performance.
The Series 300 range of equalisers is a direct result of this research. It should be noted that graphic equalisation
cannot always overcome all frequency response related problems. There are applications where the ability to cut
and boost the response at a particular frequency, or over a certain bandwidth other than the equaliser specified
one, is required to overcome exceptionally difficult response anomalies or narrow band feedback problems.
When such an instance is encountered, it may be more appropriate to use the greater range of control provided
by a parametic type equaliser, where the centre frequency, bandwidth and amplitude are all controllable.
Reliability is also of paramount importance which is why our filters are designed around a technique commonly
used in computer manufacturing - thick film engineering. This technique has enabled Klark Teknik to build these
new filter circuits into self-contained packages which are referred to as
. These micro-electronic
circuits are so consistent and reliable that we are able to warrant those solid state devices for 5 years. This
type of "fit and forget" technology, already proven all over the world, provides users with products that perform
brilliantly year after year.
When using an equaliser remember that the need to use large amounts of booth or that within the equalisation
curve indicates that there may be something fundamentally wrong with the sound system or room acoustics,
which should be further investigated and corrected before final equalisation is applied.
