Overview |
The Square ONE Graphic from Klark Teknik
is a dual-channel, thirty-band, third-octave graphic equalizer, with
long-throw, forty-five millimeter faders. The unit is constructed to the
same standards as the rest of the Klark Teknik range, while answering to
more budget-sensitive applications.
Aside from the main filters, the unit sports a high- and low-pass filter
per channel. These filters manage subsonic and ultrasonic frequencies
respectively, providing protection for speakers while increasing the
available headroom for the entire system. When engaged simultaneously,
the filters provide optimal control over the operating bandwidth of most
monitor (floor wedge and IEM) transducer systems.
The unit utilizes proportional-Q filtering, which varies the "Q" value
depending on the depth of either the cut or boost of a particular band.
This results in a "smooth" and "musical" response, while still
preserving the original source material. Both inputs and outputs are
balanced. The internal power supply automatically adjusts itself to
various voltages, from 100 to 240VAC.
The Square ONE graphic represents 30-years
of Klark Teknik's design expertise, offered at a more accessible price
point, bringing superb audio performance within reach of the most budget-sensitive
applications.
The Graphic Equaliser shall allow have
one fixed second-order high pass filter with an 80 Hz corner frequency
and one fixed second-order low pass filter per channel with a 12 kHz
corner frequency.
The Graphic Equaliser shall have an equalisation section by-pass and
shall be fail-safe, that is the unit shall return automatically to the
by-pass condition in the event of power supply interruption.
The Graphic Equaliser shall use centre-detented slide potentiometers
arranged to give a graphical display of frequency plotted against level.
The slide potentiometers shall have protective covers to inhibit the
ingress of dirt and dust.
All audio connections shall be electronically balanced and use XLR and
1/4" TRS jack connectors.
The Graphic Equaliser shall be capable of operating from a 100-240V +/-
10% 50/60Hz a.c. power source.
The Graphic Equaliser shall be the Klark Teknik Square ONE Graphic, and
no alternative specification option is available. |
