Graphic equalisers can be invaluable for counteracting poor room or venue acoustic problems such as feedback and reverberation. The audio spectrum is divided across 31 notch bands each adjustable plus or minus 6 or 12dB from centre or flat position. Feedback or reverberation can be reduced or eliminated by “notching out” ie. reducing the system frequency response at the offending frequency sector. Usually connected between the pre amp out and power input of the sound system amplifier. An earth lift switch helps eliminate mains earth loop hum and buzz. High pass and low pass selectable filter switches provide filters of 12dB per octave below 40Hz and above 16kHz respectively. Three different types of connectors are provided for connection to the amplifier. 3 pin XLR and 6.35mm sockets offer balanced connections, whilst RCA sockets provide unbalanced operation. A switch is provided to bypass all control settings. Overall output is controlled by the level control.
Removal of AC power in the ON position puts unit into bypass mode making this suitable for 24V backup systems
