Overview

At its core, PMX-1 is a digital stereo performance mixer with three stages. The first stage, the input stage, provides 16 stereo inputs. The stereo inputs are duplicated, each input is routed into two stereo channels with its own saturator, equalizer and compressor. These 32 channels are then feed into the second stage, the group stage. The Input Channels section describes the input stage in more detail.

The group stage consists of two group mixers, each of them grouping 16 channels from the input stage, so that each group mixer receives every signal present at the inputs. Those are routed into 4 group channels, each with a compressor and an equalizer. In practice, this means that means that PMX-1 creates two completely mixes, called layers, which are feed into the third stage, the layer stage. The Group Channels section describes the group channels in more detail.

The layer stage provides 2 stereo channels, each the input for 4 group channels, of for each group mixer in the group stage. The layer stage combines those to one stereo channel, the output of PMX-1. The Layer Channels section describes the layer channels in more detail.
