Page 4 1.0 introduction the eqx20 is a two channel 3 band parametric equaliser which can also be configured as a single channel 6 band unit. Each band offers variable frequency, 15db cut and boost and variable q (bandwidth). Having all parameters fully variable makes the eqx20 a powerful tool capabl...

Page 6 • please check that your unit is correctly rated for the voltage of the country of operation. If the fuse requires changing at any time please ensure the correct fuse is fitted. An incorrect fuse could cause damage to the unit and may constitute a fire hazard. If you carry your eqx20 from one...

Page 9 4.0 description of controls 4.1 channel 1 lf control this control sets the amount of cut or boost for the lf (low frequency) section. Gain range on the eqx20 is ±15db. The following diagram shows the effect of different cut and boost settings. Maximum cut or boost occurs at the centre frequen...

Page 12 bypass switch pressing bypass switches the eq out of the signal path and allows a/b comparison. Remember if you are using any amount of boost, bypassing the eq will cause a noticeable drop in signal level. In mono mode channel 2 bypass is inoperative and channel 1 bypass now switches the who...
