Classic compressor revamped for the 500 series
The Solid State Logic B-DYN 611B 500 Series Module is a faithful recreation of the dynamics processing found in the iconic SL 4000 B consoles. Basing its design on the SSL Bus Compressor, this module is built to deliver top-quality dynamics control for your audio productions. With its authentic design and components, you can expect the same legendary SSL sound and performance that professionals have come to rely on.
Versatile compressor/limiter section with built-in high-pass filter
The B-DYN 611B features a versatile Compressor/Limiter section that offers precise control over your audio signals. With stepped compression ratios of 2:1, 4:1, and 10:1, as well as a 'ds' setting that delivers a fixed 10:1 ratio with additional sidechain filtering, you have the flexibility to shape your sound to perfection. The Threshold control determines at what level the compressor starts acting, while the Ratio control determines the intensity of compression. Additionally, both controls provide automatic make-up gain, ensuring a consistent and balanced output.
To help reduce unwanted bass pumping effects, the Compressor/Limiter section also includes a 6dB/Oct 185 Hz High Pass Filter in the sidechain. This filter allows you to target specific frequency ranges and maintain greater control over your audio dynamics. Release times are an essential aspect of dynamics processing, and the B-DYN 611B offers precise control in this area. With fixed release times ranging from .2 ms to 1.6 ms, as well as additional 'DS' (De-Ess) and 'Auto' release options, you can tailor the release characteristics to suit your specific needs. The DS mode is particularly useful for reducing sibilance, with an attack time reduced to a fast 2 ms, providing excellent control over harsh consonants and high-frequency content.
Advanced de-esser mode
By setting the Compressor Ratio and Release controls to 'DS', the B-DYN module optimizes its processing for reducing sibilance, commonly known as De-Essing. In this mode, the module operates with a fixed 10:1 ratio and a filtered sidechain input signal that triggers the compression specifically on sibilant sounds. The 'DS' release time is automatically adjusted between 30 ms and 50 ms, offering a faster and more precise release than what is typically expected from an SSL Dynamics section. Additionally, the attack time is reduced to a swift 2 ms, allowing for a quick and effective reduction of sibilance and ensuring a smooth and balanced vocal performance.
Control your dynamics with the Gate/Expander
The B-DYN 611B module also includes a versatile Gate/Expander section that provides effective control over signal dynamics. With a 20:1 Gate ratio or a 2:1 Expander ratio when the EXP button is engaged, you have the tools to shape the envelope of your audio signals precisely. The attack time is set at a speedy 0.2 ms, allowing for instant accurate response. The RANGE control determines the maximum amount of gain reduction applied by the Gate/Expander, providing a wide range of control options. When set to 'out', the Gate/Expander is bypassed, allowing for a transparent signal path.
The THRESH control sets the threshold above which the gate or expander will be activated, giving you precise control over when the processing takes place. And with the RELEASE control, you can set the duration for which the signal remains audible after the Gate/Expander closes, ensuring a smooth and natural decay. With the EXP button engaged, the gate is switched to expander mode with a gentle curve, providing subtler control over the level below the threshold. This feature allows for more nuanced dynamics shaping and ensures seamless integration of the processed audio with the rest of your mix.
