Stereo 4-band Equaliser
Inspired by the channel EQ from a popular 1970s console, Coleman Audio's CA500EQ is a stereo 4-band equaliser that offers a broad range of sound-shaping capability. Several unique and thoughtful features set the CA500EQ apart from most EQs we come across at Sweetwater. Housed in a sturdy and attractive 2RU chassis, the CA500EQ provides stepped switches for easy settings recall. An 18dB/octave high-pass filter, continuously variable from 30Hz to 300Hz, is included for ridding your signal of unwelcome low frequencies. Inputs and outputs are via balanced XLR connectors. Per-channel bypass, polarity, and EQ In switches complete the feature set.
The CA500EQ's EQ circuits are designed to musical scales, rather than mathematical relationships - an under-the-hood benefit that helps impart a highly musical quality to signals you've processed through the CA500EQ. Another sound-enhancing feature is the inclusion input and output level controls that let you adjust your signal strength before and after equalisation for optimal gain structure. Lastly, with the mono button engaged, the audio passes through the left channel first and cascades over to the right channel, which extends your EQ options without having to re-patch.
Unlike many equalisers whose EQ points are selected on the basis of mathematical relationships, Coleman Audio based the CA500EQ's on musical scales. The low-frequency filters (30Hz, 60Hz, 100Hz, and 150Hz) are shelving, with 10dB of boost or cut in discrete 2dB steps. The high frequencies (8kHz, 10kHz, 12kHz, and 16kHz) are also shelving, again with 10dB of boost/cut in 2dB steps. The two mid bands are peaking, with their frequencies overlapping by a quarter-octave and offering up to 14dB of boost/cut in discrete 2dB steps. The 18dB/octave high pass filter is variable from 30Hz to 300Hz and has an on/off switch independent of the EQ In switch.
