Q-215
Q-215

The Q-215 is a dual channel 15 band 2/3 octave graphic equalizer using constant Q filters to maintain even bandwidth irrespective of gain ensuring transparent adjustments even with extreme gain settings. The Q-215 fits into a convenient 1U 19" rackmount chassis and has inputs and outputs on XLR and 1/4" TRS balanced / unbalanced connectors. Ground lift switches can eliminate any earth loop or hum issues. Power is supplied via an IEC connector.

A switchable 40Hz HPF allows for removal of unwanted low end rumble that in turn increases overall system headroom.
