CQ15/CQ31 OVERVIEW
• Stereo 15-band (CQ15) or monophonic 31-band (CQ31) graphic EQ
• Built in optical compressor / limiter per channel
• Selectable pre- / post-EQ compressor operation with true circuit bypass
• Balanced and unbalanced inputs and outputs
• Euro Block input and output connectors for fixed installations
• 1U rugged metal case construction
The CQ15 and CQ31 combination graphic equalizers / optical compressors offer
control over both frequency and level in a convenient single-space rackmount
format. The stereo CG15 and monophonic CQ31 are ideally suited for a variety of
live and installed sound applications, and are equally at home in the equipment
racks of bass players, keyboardists, and DJs.
Each of the CQ15’s two channels features 15 bands (2/3-octave) of equalization
with selectable ±6dB / ±12dB range. The compressors, one per channel and
available pre- or post-EQ (and featuring true circuit bypass) are designed to
address a variety of tasks, from harnessing troublesome peaks to putting a tight
low end on a stereo DJ mix.
When finer band-resolution is required, the CQ31 offers a full 31 bands
(1/3-octave) of equalization with selectable ±6dB / ±12dB range, topped off by
a fully adjustable optical compressor. As with the CQ15, the compressor is
available pre- or post-EQ and features true circuit bypass.
