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 whole EQ in and out of circuit.

75Hz switch

Pressing this switch inserts a 75Hz, 12dB/Octave slope high pass filter into the signal path before the EQ section. Primarily intended to remove subsonic frequencies such as stage noise the filter can be used in conjunction with the LF EQ section to tighten a flabby bass sound - see applications.

In MONO (6 Band) mode only the filter switch on Channel 1 is enabled.

MONO led

Pressing the MODE switch on the rear of the EQX20 lights the MONO led. This puts the two EQ channels in series to form a single mono 6 band unit. In this mode the BYPASS and 75Hz filter switches on Channel 2 are disabled. Channel 1 BYPASS now switches the whole EQ in and out of the signal path.

Your input signal should now go to Channel 1's input and the output taken from Channel 2's output. Channel 1 will still output signal but Channel 2's input is disabled - see applications

5.1CHANNEL 2

Channel 2 is similar to Channel 1 except for the Input, BYPASS and 75Hz filter switch when used in MONO mode.

POWER indicator

The green POWER led is lit whenever mains power is supplied to the unit.
