All The Effect Processing You Need Built-In

12 Input Channels
The MG12/4FX features a total of 12 input channels: four mono microphone/line inputs and four stereo line inputs, two of which offer mono microphone input capability. Gain trim covers a wide -60 dB thru -16dB range for microphone input, and -34dB thru +10dB for line input.
A Variety of Input Connectors
Balanced XLR connectors are provided on all four mono inputs and two of the stereo inputs a total of six XLR connectors, in addition to phone jack connectors. Two of the stereo channels can accept mono microphone input either via the XLR or phone jack connectors.

A separate stereo 2TR input with pinjack connectors is provided for independent input of signals from CD players or similar sources.
Six Low-noise, High-precision Mic Preamps

Phantom Power
All high-performance mic preamps feature switchable phantom power for studio condenser microphones. A single switch turns phantom power on or off for all channels.
Insert I/O
Mono input channels feature insert I/O patch points so you can add compressors or EQ for vocals, a noise gate on a guitar channel, or other extra signal processing to individual channels as required.
3-band Channel EQ & HPF
Smooth, "musical-response" 3-band equalizers are provided on the input channels. All mono microphone input channels also feature a switchable high-pass filter that can be used to cut out unwanted low-frequency noise.
Four Buses (Stereo and Group)
In addition to the main stereo bus, the MG12/4FX features a stereo group bus and outputs that can be used for convenient channel grouping. Stereo and group bus assign switches are located above each channel fader. You could, for example, mix your instrument sources to the stereo bus while creating separate groups for the main vocal and chorus channels...or any bus configuration you need for your application.
