Dugan Model E-3 User Guide Operation

5. Balance the preamp gain controls so the fluctuating ambient noise registers equal-

ly on the Model E-3’s meters.

Note that raising the preamp gain of one channel causes its gain to rise and the

others to fall; it’s a balancing act. When balanced, all mics have equal access to

the system gain.

6. If clipping occurs because someone speaks louder than expected, turn down all of

the console’s input trim controls the same amount, which maintains the ambient

noise balance.

Figure 4-4 During ambience with 4 mics, auto mix gain displays should hover around -6 dB

Figure 4-5 During ambience with 8 mics, auto mix gain displays should hover around -9 dB

TIP: To eliminate an unwanted noise in the mix, use the gain displays to locate the offending

channel and activate its mute button.

If You Must Use a Pre-fader Insert

The Dugan Speech System is more convenient to operate if patched post- rather than

pre-fader. If your console allows this, skip this section. If you use a pre-fader insert,

this section describes how to properly mute and pre-listen to muted channels.

Muting Channels

Mics must be muted by using the Dugan’s mute buttons. Pulling a fader down on the

console will not properly mute a channel. Although that mic is no longer audible in

the mix, it still contributes to the gain computations and causes ambient noise fluc-

tuation. In the worst case, this could cut off a speaker.
