The EQ-2215 from Inter-M Americas is a dual channel, 15-band, Constant Q graphic equalizer designed for permanent installation in commercial and professional sound reinforcement applications and packaged in a low-profile 2RU enclosure.
Two banks of forty-five millimeter slider controls allow accurate boost/cut band settings of +/-6dB or +/-12dB (selectable) along with -12dB/24dB cut-only operation. Switchable 80Hz high-pass filters per channel eliminates subsonic rumble and helps protect against low-frequency damage.
A front-panel EQ bypass switch (or lack of AC power) will bypass the equalizer circuitry.
