Each of MC4’s four dynamics channels can be configured for independent mono processing, linked stereo operation, or Mid/Side processing. Stereo linking ensures coherent gain reduction across paired channels, preserving image stability when processing stereo sources. Mid/Side mode provides precise control over the centre and edges of a mix, enabling targeted dynamic shaping of vocals, bass, ambience, and width without compromising mono compatibility.

Brick Lane MC4’s Series mode allows two dynamics channels to be routed in series within a single signal path, enabling sequential dynamics processing without external patching. Each stage operates independently, with its own dynamics settings and Modal PWM saturation characteristics. By dividing gain reduction across two stages, Series mode enables more controlled and predictable dynamics behaviour than a single processor operating aggressively.

Dual-Band mode splits a source into low- and high-frequency bands, with each band processed by its own Modal PWM dynamics channel before being recombined.  The dual-band architecture is specifically optimised to minimise the unwanted artefacts and phase interaction that can be present in traditional analogue multi-band compressors - reducing crossover complexity while preserving the coherence and integrity of the original signal.

Brick Lane MC4 features bypassable TRS insert points on all four dynamics channels, with each insert point being user-selectable within the processing chain. This flexibility allows the inserting external equalisation, saturation, or other analogue processors either before or after dynamics processing. In Mid/Side operation, the insert points may be positioned between M/S encoding and decoding, enabling external hardware to be applied independently to the Mid or Side components of a signal.

Also provided are four assignable external sidechain inputs alongside a flexible internal sidechain routing system, allowing each dynamics channel to independently select its control signal source. This routing flexibility allows dynamics behaviour to be decoupled from the audio signal path when required, enabling precise control without altering the processed audio.
