British Console Equaliser Algorithm

Discrete Class A channel amplifier modules designed for British consoles in the early 1970s are characterized by their unique sonic qualities: tight and balanced low end, wide and smooth mid range and a warm yet lustrous high end. The BEQ2 Algorithm accurately and efficiently simulates these remarkable characteristics in the digital domain with its meticulously designed semi-paragraphic topology. It is the ultimate tool for those of us who can never have enough classic British peaking bands.

Key Features

  • Extremely High Processing Efficiency.
  • Supports sampling frequencies up to 384 kHz.
  • Clickless parameter update.
  • Proprietary topology which is optimized for low latency, low noise and high dynamic range.
  • Supports both 32 bit (single precision) and 64 bit (double precision) floating-point processing.
  • Built-in reference-quality upsampling algorithm which can be enabled at sampling frequencies 44.1 kHz and 48 kHz to achieve bell shape symmetry at high frequencies.
  • Clearly and concisely implemented in pure C++: portable to any platform that is supported by a C++ compiler.


BEQ2 British Console Equaliser Algorithm features twelve bands with continuously variable bandwidths which have the center frequencies 35Hz, 60Hz, 110Hz, 220Hz, 360Hz, 700Hz, 1.6kHz, 3.2kHz, 4.8kHz, 7.2kHz, 10kHz and 12kHz. The amount of boost or attenuation is continuously variable from -18 dB to 18 dB on all bands.
