Overview of Trim / Faders / Gain / PFL

Trim vs Faders

The gain of an input is adjusted by two controls, Trim and Fader. This two-stage architecture is identical to the topology of large mixing consoles and provides a great deal of control. Trim is often thought of as a coarse gain control and the Fader as the fine gain control.

The Fader is the primary control used while mixing, and it affects the level of input signal routed to all post-fade destinations. Use the Fader control to make fine gain adjustments.

The Fader control can be attenuated from off (at full counter-clockwise position) to +16dB above the set trim level (at full clockwise position). Operate input faders at or near 0dB, the unity gain (12 o’clock) position to optimize gain structure for the best performance.
