2. Press the soft ROUTING (REWIND) key to enter the Track Routing View.
3. Use the Rotary Switch to navigate through the Track Routings. If a number is displayed the
corresponding input is assigned to the given track.
4. Press in on the Rotary Switch to toggle the routing of an input to a track.
Routing Using the CL-8
From the CL-8 the user can quickly make input to track routing changes to the Left, Right, Aux 1,
and Aux 2 Tracks.
See CL-8 Controller section for more details.
Routing Using the CL-9
From the CL-9 the user can quickly route any Input to any Track. See CL-9 Linear Fader Controller sec-
tion for more details.
Mix Assist™
Mix Assist™ is a powerful feature of the 788T which can automatically attenuate the level of any
microphone which is not active, reducing the background noise level in the mix. This function is
commonly referred to as “automix”. The 788T’s MixAssist™ feature automixes post-fade signals to
the L and R tracks.
Pre-fade signals are not affected by Mix Assist .
Inputs that are automixed will be “open” (unattenuated) when a person talks into the input’s micro-
phone and “closed” (attenuated) when the person stops talking. Microphone channels open within
1 mS to ensure that no syllables are lost, and then will gate off smoothly over 500mS. This gating
action is smooth and imperceptible when switching between microphones. Mix Assist will allow sev-
eral microphones to be open simultaneously if there are several talkers - Mix Assist does not limit the
number of open microphones.
Mix Assist is more sophisticated than a simple gate, and uses four different principles to automix
input signals.
Noise Adaptive Threshold
An input with Mix Assist enabled will be smoothly attenuated by 20 dB when its microphone is be-
low the adaptive threshold. The threshold is not a static level (as with the limiter or simple gate) but
a level which changes dynamically based on the average level of the input. This prevents common
background noise (fans, crowd murmur, etc) from causing the input to open, while allowing normal
sounds to open the mic.
Number of Open Microphone Attenuation
As the number of open inputs increases, the level of each input as it is routed to the track will de-
crease by 3 dB per doubling of open mics. This ensures that the overall level of the track is consistent
regardless of the amount of open inputs routed to it.
