Input Channel - Analog Trim - QSC TouchMix-30 Pro User Manual

Input Channel – Analog Trim
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. – Located above the
Trim Controls
touchscreen, adjusts sensitivity of mic/line inputs
(TouchMix-30 Pro shown).
2. – Touch to select a fader bank.
