If any of these items are found to be missing, immediately contact the BBE dealer from whom the unit was purchased. WARNING!To prevent possible speaker or amplifier damage, always power-up peripheral devices first, wait 10 seconds, and then turn on the power amplifier. Turn off power amplifier first, then power-down peripheral devices. 1 GENERAL DESCRIPTION EQA231 is a two channel 31 band 1/3 octave graphic equalizer. The EQA231 incorporates Constant-Q circuitry with a 5% center frequency accuracy. Special features include variable Low and High pass filters, selectable range ±6dB or ±12dB, balanced and unbalanced input/output connectors, RFI filters, variable level control, passive bypass switch, PEAK LED, ground lift switch. EQA131 is a single channel 31 band 1/3 octave graphic equalizer. The EQA131 incorporates Constant-Q circuitry with a 5% center frequency accuracy. Special features include variable Low and High pass filters, selectable range ±6dB or ±12dB, balanced and unbalanced input/output connectors, RFI filters, variable level control, passive bypass switch, PEAK LED, ground lift switch. EQA215 is a two channel 15 band 2/3 octave graphic equalizer. The EQA215 incorporates Constant-Q circuitry with a 5% center frequency accuracy. Special features include selectable range ±6dB or ±12dB, balanced and unbalanced input / output connectors, RFI filters, variable level control, passive bypass switch, PEAK LED, ground lift switch.

EQA231 The EQA231, EQA131 and EQA215 all offer the same high quality Constant-Q performance. Constant-Q graphic equalizers were developed to fill the sound professional’s need for greater control over sound shaping with less interaction between sliders. Truth in slider position became a requirement. The curve traced out by the slider positions on Constant-Q designs indeed represent the actual change to the frequency response. On conventional designs they do not. Only for EQA131 and EQA 231 FRONT AND REAR PANELS 4 FRONT AND REAR PANELS EQA215 EQA131 1. Power Switch 2. Filter Level Controls 3.

Power Switch This switch is pressed to turn power ON, pressing the switch again turns the power off. Always turn on your equalizer BEFORE your power amplifiers are turned on, and always turn off equalizer AFTER your power amplifiers have been turned off. 2. Filter Level Controls Each of these sliders control the output level of each of the 31 (or 15) bandpass filters. Center detent position is grounded for guaranteed flat response. 3. Filter Range Switch & Indicators The gain range of the filter sliders is switchable (as a group) from +/-6dB to +/-12dB for maximum boost/cut capability. When this switch is in the "OUT MOST" position, at 6dB, the green LED wil...
