Mic Input
A gold-plated balanced female XLR connector accepts balanced or unbalanced mic signals. At -127dbu EIN the mic amp is extremely quiet and transparent with excellent overload characteristics.
Line Input
A balanced 1/4" jack for connecting balanced or unbalanced electronic instruments, such as keyboards.
Insert
Used for patching in compressors or additional EQ or for other signal processors. It can also be used for recording to multi-track recorders if necessary.
Gain
A rotary gain control on each input alters the gain of the input signal, from +5 to +60dB (Line Inputs have -15dB attenuation). Linear circuitry within the preamp delivers smooth gain control over the entire gain range.
EQ Section
Equalisation is split into three bands. The shelving HF control provides 15dB of cut or boost (gain adjustment) for frequencies above 12kHz. A swept mid frequency control enables frequencies from 150Hz to 3.5kHz to be adjusted with up to 15dB of cut or boost at the selected frequency. Signals below 80Hz can be adjusted with the LF control, which features ±15dB of gain adjustment (cut or boost).
Auxiliary Section
Two (MFXi) or three (MPMi) Aux sends for sending separate monitor mixes in live applications, or for use with external effects. In the Master Section, each Aux bus has its own master level control and AFL. Aux 1 is fixed pre-fade, Aux 2 is switchable pre or post-fade, and Aux 3 (FX on MFXi) is set post-fade.
FX Send
For sending signal to the internal 24-bit Lexicon effects.
Pan, Muting, PFL and Routing
The Pan control positions each channel's signal across the stereo image, with an illuminated Mute switch to cut the signal completely. A PFL button solos the signal for monitoring. The mono channels can be routed to either the main Mix outputs or the Sub Groups via the Mix/Grp switch.
Faders and Metering
Each mono channel features a smooth 60mm fader, along with Signal Present and Peak level indicator LEDs, which are located just above the fader for easy viewing of signal status.
STEREO INPUT CHANNEL
|
Input Connectors
The stereo inputs are connected via balanced 1/4" jack inputs, delivering optimum performance with other professional audio equipment.
EQ Section
There are three fixed shelving controls, adjusting HF signals at 8kHz by ±15db, MF signals at 720Hz by ±15db and LF signals at 60Hz by ±15dB.
Auxiliary Section
With 2 (MFXi) or e (MPMi) Aux sends on the stereo input channels, the signal can be sent pre-fade (Aux 1), pre or post-fade (Aux 2) or post-fade (Aux 3/FX). Aux 2 is switchable pre or post-fade on the Master section.
FX Send
For sending signal to the internal 24-bit Lexicon effects.
Bal, Muting, PFL and Routing
The balance control adjusts the amount of the signal sent to the left and right busses.
Mute and PFL
buttons operate as on the mono input channels, cutting or soloing the stereo channel. With PFL pressed, the prefade signal is fed to the headphones, control room output and meters. The stereo input channels can be routed to either the main Mix outputs or the Sub Groups via the Mix/Grp switch.
Faders and Metering
Each stereo channel features a smooth 60mm fader and a peak level LED indicating signal levels in excess of +17dBu.

MASTER SECTION
|
Effects
A rotary control selects the effect program, with three rotary controls for effect parameters and two to control the effects level sent to Auxes 1 and 2. Buttons for PFL, Mute, Store (user effect set-up) and Tap Tempo (for time/speed-based effects such as delays). Footswitch input for FX on/off. The FX return fader has both Signal present and Peak LEDs for easy viewing of signal status. The FX master has AFL switching to check the level of the signal being sent to the FX section (or external processor).
+48V Phantom Power
Global control over professional +48V phantom power is offered via a push button. When active, an LED will illuminate.
2-Track Inputs and Outputs
2-track recorder playback inputs and record sends are on unbalanced RCA phono connectors. The Playback to Mix control routes the signal directly to the main mix, replacing the signal that is present.
Monitor Switching
Monitor outputs are selectable from 2-Track input, and Mix or Sub outputs.
Monitor Outputs
Available on balanced 1/4" jacks, the Headphone and Control Room monitor outputs feature independent level control.
Mix Outputs
The main left and right mix outputs are provided on balanced XLR connectors.
Stereo Return
Available on 1/4" jacks with level control for use with external processors.
Sub Groups
Control over the Sub Groups comes via L-R Sub Group faders. The Sub Group outputs are 1/4" jacks
Faders and Metering
L-R Group faders control the Sub Group levels while overall stereo mix is handled by a single 60mm fader, with two 10-segment 3-colour LED peak-reading bargraph meters monitoring the mix left and right outputs. These meters normally follow the current monitor selection, so if any PFL button is pressed, the meters will switch to monitor this and the PFL Active LED will light.
