Sub Group Neumann summing for Multi–Bus Compression


A subgroup, also referred to as an aux group

aux track, aux bus, sub bus, or Group Channel, serves as an auxiliary channel within your DAW’s mixer. It’s a temporary destination for the selected tracks before they reach the master output (often called the stereo output, master bus, master track, or 2-bus).

Subgroups provide the means to control the volume of multiple tracks collectively

all while preserving their relative balance. A single fader adjustment achieves this, and they also offer the convenience of applying processing to all these tracks at once.N

Why Use Subgroups?

Subgroups trace their roots back to analog mixing consoles, where they were hardware-based components integrated into the mixer, offering a fixed number of available subgroups. In modern DAWs, their utilization is far more adaptable. You can generate as many subgroups as required, and the added flexibility allows you to route one subgroup into another, offering increased control and creativity.

This Neumann mixer has six (6) sub-mixers (ABCDEF) with dedicated inputs. Each sub-mixer group comes with an individual insert send/return for external processing, which then returns to the Master for the final summing.

Sub group is a set of tracks together

whatever audio tracks you’d like to group in a submix, create an aux track and then route to the main outputs or to post insert TRS, second mixer like Chandler then return via XLR to main master sum through Neumann transformers.
