Elliott Sound Products Project 84 - 8 Band Constant Q Graphic EQ for Subwoofers

The layout for this circuit is unchanged from the published project design. It is a versatile Constant-Q equaliser, and can also be used anywhere that 8 bands of EQ is sufficient, including musical instrument amps or car sound systems.

The PCB comprises a complete 8 band constant Q equaliser, with provision for rotary pots to mount on the PCB. It uses 9mm square pots (also available from ESP). Requires a power supply (e.g. P05) giving +/-12V to +/-15V at about 40mA.
