Pre- or post-fader routing to the X1, X2, X3 and X4 tracks is a global setting that applies to all
inputs routed to the X1, X2, X3 and X4 tracks. This option is configured from theX1, X2 Routing
Screen and the X3, X4 Routing Screen.
Pan Control
The pop-up Pan Control routes Inputs 1, 2, and 3 to the left (L) and right (R) channels of the stereo
Master Bus. The pan pot has a detent in the center position. After setting the pan, the pan control can
be recessed to hide it from the mixing surface during normal operation.
Inputs 4, 5, and 6 are routed directly to the left (L) and/or right (R) channels of the stereo Master Bus
from their respective Input Settings Screens.
Trim and Fader Relationship
The gain of an input is adjusted by two controls, Input Trim and Input Fader. This two-stage archi-
tecture is identical to the topology of large mixing consoles and provides a great deal of control.
Input Trim is often thought of as a course gain control and the Input Fader as the fine gain control.

Input/Trim (Analog)
Analog input sensitivity for Inputs 1, 2, and 3 is set with the pop-up Trim control knob. Analog input
sensitivity for line-level Inputs 4, 5, and 6 is set by rotating the Select Encoder from the respective
input’s Input Settings Screen (Off, -30 dB to 16 dB). To power down Input 1, 2, or 3 turn the respec-
tive trim control fully counter-clockwise until it clicks.
With the Input Fader set to unity gain (0 dB or 12 o’clock), make the appropriate adjustments to trim
levels. Once the coarse gain is set to the desired level, press the Trim control to hide it from the 633’s
mixing surface.
Input Trim (Digital)
The coarse level of a digital input is set by rotating the Select Encoder in the Input Settings Screen of
an input with a digital source. The digital trim level is displayed on the LCD. The digital trim level is
adjustable from -30 to +16 dB.
