Cranborne Audio Bricklane Compressor 500 Series Module


Brick Lane 500: The Modal Compression Revolution

500 Series analogue PWM Compressor with 6 operating modes and variable Stress control for harmonically-enriched compression effects.

A Technological Breakthrough in Dynamic Processing

The Brick Lane 500 represents a quantum leap in analogue compression —  a fully-analogue PWM Compressor that transcends traditional dynamics control methodologies through its revolutionary Modal PWM Compression architecture.

Features

  • 500 Series Modal PWM Compressor meticulously developed by the Cranborne Audio team in the UK

  • Custom PWM compression circuit and unique ‘Stress’ control for Harmonically-enriched compression effects

  • 6 Compression modes - Velvet, Float, Smash, Tame, Glue, and Polish set compression ratio, knee, compression style, and compression rate of change.

  • Threshold control and variable-range Attack and Release controls (altered per mode)

  • 12-segment LED level meter and 12-segment LED Gain Reduction Meter

  • 4 selectable sidechain HPF modes - OFF, 60Hz, 100Hz, 200Hz

  • ±20dB Input and Output/Make-up Gain Level to tailor the compression and saturation character to the source

  • OptoSync wireless communication between modules for linked controls during stereo operation

  • ⅛” TRS socket for linking non-adjacent modules

  • Circuit auto-calibration for perfect stereo matching between all modules

  • True-bypass IN/OUT switching with complete or post input trim modes available on DIP switch

  • Stepped, front-panel controls for quick recall and precise feel

All specifications are typical performance unless otherwise noted. All specifications are subject to change at any time. Tested with Audio Precision APx555.
