Page 7: Introduction
The GQ600 combines innovative features with impressive specification, to produce a new level of performance in professional equalisation. The GQ600 is a precision dual channel 1/3 octave graphic equaliser, which provides up to 10dB of boost or cut at 30 centre frequencies between 25Hz and 20kHz. Filter design has been carefully optimised for good interpolation and improved narrow band performance, whilst high quality long-throw 45mm sliders are used for better resolution. - Page 8 Response of a single 1/3 octave filter section. Combining effect with sliders set to achieve +10dB overall gain. Note lack of amplitude ripple. Response of H.F. Trim frequency control. At maximum and minimum gain. GQ600 Page 6...

Page 9: 1/3 Octave Centre Frequencies
This leads to unequal spacing of filters if these marked frequencies are used to calculate filter values. The GQ600 uses true 1/3 octave frequencies based on 1kHz as a reference, and each filter is automatically tested and adjusted when required, to achieve a centre frequency accuracy of within ±3% of these true 1/3 octave frequencies. -

Page 13: Operating Notes
Operating Notes Generally, operating the GQ600 is very straightforward, however certain functions may not be immediately obvious and these are discussed here. Low Pass Filter. 18dB/octave filters are provided for each channel to provide additional H.F. driver protection against unwanted high frequency signals. These have negligible effect on frequency response at 20kHz. -
