Insert Patching
Figure 2-2 Post-fader insert patching
The Dugan Speech System is best patched post-EQ, post-fader, pre-compressor:
• Post-EQ: Equalization can be applied to different mic types so they sound more alike,
which benefits both the sound quality and the automixing process.
• Post-fader: This allows muting a channel on the console by pulling down the fad-
er or activating the mute button. Patching the Dugan pre-fader leaves the mic in
the automix even when the fader is down or the console channel is muted.
Most analog consoles only have pre-fader inserts. You can use Dugan automixing
with these consoles but you must be careful to mute channels by muting on the
Dugan, not the console.
• Pre-compressor: The Dugan Speech System works on the level differences between
channels. Compression reduces level differences between channels, making auto-
mixing less effective. It is OK to patch post-compressor if only occasional peak
limiting occurs. However, if compression is active during normal speech, better
results will be obtained by patching the Dugan pre-compressor.
