The Trim (gain) control sets the level of the analog input
signal just before conversion to digital. The Trim controls
are not available on the remote devices. Only Mic/Line
Input Channels have Trim controls.
NOTE: Proper gain trim adjustment
prevents clipping, improves signal-to-noise
performance, and allows preset
compression and gate dynamics to
function asintended.
NOTE: The mixer also has digital gain
trim. Its settings are stored and recalled
with scenes and presets. See “Input
Channel Setup” for more detail.
The following controls and indicators are used to set the
input gain Trim:
1. Trim Controls – Located above the
touchscreen, adjusts sensitivity of mic/line inputs
(TouchMix-30 Pro shown).
2. Nav Strip – Touch to select a fader bank.
• The red line in Inputs 1-8 fader bank is a clip
indication that is persistent (sticky). It is cleared
using the “Clear Clip” function (User Button 2) or
from the Menu screen. Clearing the indication
affects only the device (tablet or mixer) on which
it was cleared.
3. Level Meter (Mic 1) – Indicating that the
signal level in the channel is below unity. If input
gain trim is properly adjusted, this will be seen when the source is playing somewhat below its average level
4. Level Meter (Mic 2) – Indicating that the signal level in the channel is slightly above unity. If input gain trim is properly adjusted,
this will be seen when the source is playing at its average level.
5. Level Meter (Mic 3) – Indicating that the signal level in the channel is above unity. If input gain trim is properly adjusted, this
will seen when the source is playing somewhat above its average level.
6. Level Meter – Indicating the channel is clipping. Reduce the source output level or mixer input gain and clear the clip indication (User
Button 2).
7. Input Channel Fader – Adjusts the output of the channel to the Main L/R outputs, post-fader aux. sends, and Sub-Groups
(TouchMix-30 Proonly)
