PRECAUTIONS
Precautions Introduction
Front Panel Rear Panel Audio Connections Specifications
Before connecting the unit to the mains power, ensure
that the operating voltage is correct for your local
supply. It is important that you observe the following
instructions if another voltage setting is required. Do not
install this unit in a location subjected to excessive heat,
dust or mechanical vibrations.
VOLTAGE SELECTION and POWER CONNECTION
Connection is made by means of an IEC standard
power socket. The rear panel voltage label, indicates
the voltage required for satisfactory operation of the
unit.
Before connecting this unit to the mains supply, ensure
the fuse fitted is the correct type and rating is as
indicated on the rear panel, adjacent to the fuse holder.
*Mains voltage change should be carried out by a
qualified service technician only.
SAFETY WARNING
This unit is fitted with 3-pin power socket: For safety
reasons the earth lead should not be disconnected.
Signal 0V is referenced internally to chassis via a
resistor capacitor network which provides earth loop
immunity. To prevent shock or fire hazard, do not
expose the unit to rain or moisture. To avoid electrical
shock do not remove covers. Refer servicing to
qualified personnel only.
ATTENTION!
Cables:
This product should only be used with high
quality, screened twisted pair audio cables,
terminated with metal bodied 3-pin XLR
connectors. The cable should be connected to
pin 1. Any other cable type or configuration for
the audio signals may result in degraded
performance due to electromagnetic
interference.
Electric Fields:
Should this product be used in an
electromagnetic field that is amplitude
modulated by an audio frequency signal (20Hz
to 20kHz), the signal to noise ratio may be
degraded. Degradation of up to 60dB at a
frequency corresponding to the modulation
signal may be experienced under extreme
conditions (3V/m, 90% modulation).
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 UNiKA KT-360
graphic equaliser will eliminate these problems, offering
you unprecedented product performance coupled with
the highest filter calibration and reliability standards in
the industry.
The KT-360 equaliser 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.
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.
