Mono Input

MIC GAIN (1) adjusts the sensitivity of both mic (XLR) and Line (1/4” jack) inputs. Both inputs are electronically balanced, and are located on the rear connector panel.

The PEAK LED (2), monitors two points in the audio path: pre-insert point and post-EQ.

The 48V switch (3) applies 48V phantom power to the input XLR. An adjacent LED indicates when the phantom power is on.

The PHASE switch (4) reverses the phase of the selected input.

HI-PASS (5) switches in the high-pass filter.

The module insert point is pre-EQ , pre-fader. It is located on the rear connector panel.

The EQ section (6) is four band, with shelving HF and LF, and swept peaking high and low mid sections.

The HF and LF sections give +/-15dB cut/boost at 12kHz and 60Hz respectively. The Lo-mid section gives +/-15dB cut/boost at 80Hz-1.9kHz. The Hi-mid section gives +/-15dB cut/boost at 550Hz-13kHz.

The section is switched in by the EQ switch (7).

Signal is sent to the AUX 1-8 busses via individual level pots (8). Aux 1- 4 are pre fader signals, whilst Aux 5-8 are globally selectable pre or post fade via switches on the master section.

Signal for the L+R (main mix), 1-2 group busses and 3-4 group busses are routed via the PAN pot (9). The pan pot positions the signal within the stereo image.

The signal in the module is turned on and off by the illuminated MUTE switch (10), and also the master mutes M1-M4 from the master section, if they are selected using the M1 - M4 switches (11).

Post-fader signal level is controlled by a 100mm fader (12).

The signal is sent to the stereo mix bus, centre bus and 4 group busses using the C, L+R, 1-2 and 3-4 switches (13). Note the use of group 1 & 2, and group 3 & 4 as 2 sets of stereo pairs.

A 4-segment LED bargraph meter (14), next to the fader, meters the signal post-EQ, pre-mute, pre-fade. The meter has a peak type response.

The PFL switch (15) feeds the pre-mute, pre-fade signal to the monitor output and phones output. An adjacent LED indicates when the PFL is on.
