Thanks thank you for choosing the xta gq600 for your application. Please spare a little time to digest the contents of this manual (figuratively speaking), so that you obtain the best possible performance from this unit. All xta products are carefully engineered for world class performance and relia...
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 an...

Gain max gain min effect of h.F. Trim gain control, with frequency set at minimum. 1/3 octave centre frequencies the 1/3 octave iso centre frequencies used on most graphic equalisers are normally 'rounded off' to whole numbers. This leads to unequal spacing of filters if these marked frequencies are...
Front panel functions 1. Output gain control - allows ±10db of gain to be applied. This control features a centre detent for 0db gain. 2. E.Q. In/out switch - selects graphic equaliser filter section in or out of circuit. 3. H.F. Trim switch. - selects h.F. Trim section in or out of circuit. 4. Trim...
Rear panel functions 1. Mains power - is connected via a standard iec socket. A compatible power cord is supplied with the unit. 2. Mains fuse - is located in a finger-proof fuseholder adjacent to the mains inlet. Always replace this fuse with the correct type as shown on the rear panel legend. 3. P...

Operating notes generally, operating the gq600 is very straight forward, 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 freque...
To avoid ground loops, cable shields should be connected to ground at one end only. The normal convention is that the shield is only connected at the output xlr. Provision is also made for separately isolating each input and output shield pin permanently within the gq600 by breaking the appropriate ...
