Heritage Audio MCM-20 Overview

The Heritage Audio MCM-20.4 is an analog 20-channel summing mixer designed to provide high-quality passive line level signal summing and coloration for mixing engineers in home, project, and commercial studios. It sums up to 16 channel inputs and four aux inputs sourced from DB25 connectors to a stereo master output where gain restoration is performed by a Class-A, 1073-style microphone preamp with four transformers.

Each bank of eight inputs is fed to a stereo subgroup and then to the main stereo out. Insert sends and returns are present for each input channel and subgroup via DB25 connectors and for the stereo master bus via XLR jacks. Each channel offers level and pan controls, mute, one stereo and two mono aux sends, and insert return selection. The stereo master and each stereo subgroup offers level, mute, and insert functionality.

Dedicated XLR 3-pin mix and monitor output jacks enable simultaneous connection to a mixdown recorder and monitoring system. Easily keep an eye on your stereo bus levels via stereo VU meters.
