6. Operating the Mixer

This section details the primary functions and controls of your AM1204FX mixer.

6.1 Channel Controls (Mono Channels 1-4)

GAIN: Adjusts the input sensitivity for the microphone or line input. Set this to achieve a healthy signal level without clipping.
COMP: (Compressor) Controls the amount of compression applied to the channel. Use to smooth out dynamic peaks.
LOW CUT: Activates the 75Hz low-cut filter to remove unwanted low-frequency noise.
EQ (HIGH, MID, LOW): 3-band equalizer for adjusting the treble, midrange, and bass frequencies of the channel.
AUX: Sends a portion of the channel signal to the AUX output, typically used for monitor mixes or external effects.
FX: Sends a portion of the channel signal to the internal effects processor.
PAN: Positions the channel signal within the stereo field (left to right).
MUTE/ALT 3/4: Mutes the channel from the main mix and routes it to the Alt 3/4 output.
LEVEL: Adjusts the overall output level of the channel to the main mix.

6.2 Stereo Channels (5/6, 7/8)

These channels are designed for stereo line-level sources and feature similar controls to mono channels, excluding GAIN, COMP, and LOW CUT. They include EQ, AUX, FX, BAL (balance), MUTE/ALT 3/4, and LEVEL controls.

6.3 Master Section Controls

PHANTOM POWER (+48V): Activates 48V phantom power for condenser microphones connected to the MIC inputs. Ensure microphones are connected before engaging.

MAIN MIX FADER: Controls the overall output level of the main stereo mix.
PHONES/CTRL ROOM: Adjusts the output level for headphones and control room monitors.
LEVEL METERS: LED meters display the output level of the main mix. Aim for levels that peak around 0 dB to avoid clipping.
