DUCK Control Switches (4-6)
These switches allow you to alter the operation of the ducking action. The two
sensitivity switches adjust the level which the signal from MIC 1 needs to exceed for
ducking to occur. Moving just switch 4 (DUCK SENSITIVITY +6dB) down (ON
position) makes the ducking detector 6dB more sensitive, so that ducking occurs with a
lower mic level. Moving just switch 5 (DUCK SENSITIVITY -20dB) down makes the
ducking detector 20dB less sensitive, so that ducking occurs with a higher mic level.
Both switches could be used together to make ducking 14dB less sensitive. Note that
switch 8 (MIC1 PAD -20dB), discussed below, also affects the ducking level, making it
another 20dB less sensitive.
Switch 6 (DUCK SHORT RELEASE), when in the ON position, makes the ducking
circuit release more quickly, returning the output to normal levels in a shorter amount
of time.
MIC Control Switches (7-10)
Switch 7 (MIC1 LOW CUT BYPASS), when in the ON position, removes the low-
frequency roll-off normally applied to the Mic 1 signal. This roll-off is designed to
remove subaudible noise, such as mechanical clicks and thumps, that might falsely
trigger the ducking circuitry.
Switches 8 through 10 (MIC1,2,3 PAD -20dB), when in the ON position, pad the
corresponding microphone input or make them 20dB less sensitive. This could be
useful with high-output microphones to prevent overdriving or clipping the inputs. Note
that the Mic 1 pad (switch 8) also affects the level applied to the ducking circuitry, as
mentioned above.
