Auto-Mixer - Nomad 6, 8, 10 And 12 Only; A-Mix Mode; Mic On Threshold; Attack - Zaxcom Nomad User Manual

MAIN MENU
Auto-Mixer -
When Auto-Mixer is on, and a speaker starts to talk, Nomad will automatically open that microphone and add that
microphone to the mix. Then when a speaker stops talking that microphone will be attenuated "closed" and essentially
be removed from the mix.
Removing unused microphones will result in a lower noise floor giving you a cleaner, better sounding mix without
having to manually ride the faders. Manually riding faders in unscripted dialog often results in missing the start of when
a person begins to speak.
Nomad's Auto-Mixer has no limit on the number of microphones that can be active at one time. The Auto-Mixer also
has a last microphone on feature; this means that even if no one is speaking there will always be one microphone
included in the mix, which will be the last active microphone. The last mic on feature allows the mix to never go to
absolute silence.
NOTE: Auto-Mix will be routed to Output Bus 1. When using Auto-Mix make sure you remove all crosspoints from
the Bus Assign Matrix for Bus 1. If any crosspoints are active they will be mixed into the Auto-Mixer audio.

A-Mix Mode

Enables Nomads Auto-Mixer and sets if the Auto-Mixer will act pre-fade or post-fade.
• Pre-Fade - The Auto-Mixer is inserted before the faders in the audio chain so only the trim control will affect the
microphone levels. Since the Auto-Mixer is before the faders the faders have no affect on the levels.
• Post-Fade - The Auto-Mixer is inserted after the faders in the audio chain and both the trim and the faders will
control the levels of the microphones.

Mic On Threshold

Sets the level that a microphone needs to be reached before that microphone opens.
When a speaker's microphone reaches the Mic On Threshold level, as indicated on the input meter, that microphone
will open and become part of the mix.
• Mic On Threshold can be set anywhere between -60dB and -10dB

Attack

Sets how fast the microphone is added to the mix when a speaker starts to talk.
• Attack can be set anywhere between 1 and 150 ms

Decay

Sets how long a microphone will stay active after the signal has fallen 10dB below the Mic On Threshold.
• Decay can be set anywhere between 1 and 150 ms

Noise Reduction

Sets how much the output noise floor is attenuated when no one is talking.
• Noise Reduction can be set anywhere between 0dB and -10dB
