The Solid State Logic B-Dyn 611B is a 500 Series compressor module that encapsulates the dynamic processing capabilities of the legendary SL 4000 B console. This console was commercially released in 1976 and marked Solid State Logic's entry into the market. It became synonymous with prestigious recording spaces such as 'The Stone Room' at Virgin’s Townhouse Studio (London), Le Studio (Montreal), and Record Plant (LA). Notably, it left its sonic imprint on iconic records like Phil Collins’ 'In the Air Tonight' and Peter Gabriel’s 'Intruder', where its distinctive compression on vocals and drums became a hallmark.
The SSL B-Dyn 611B module allows producers to infuse their production toolkit with the rare and captivating compression style from one of the most exclusive studio consoles ever crafted. Key attributes of this module encompass a faithful replication of the SL 4000 B console's dynamics processing, drawing design inspiration from the renowned SSL Bus Compressor.
Versatile Dynamics Processing and Unique Flavour
This module includes both Compressor/Limiter and Gate/Expander functionalities. Its feedback design incorporates peak sensing for an assertive and captivating sonic character. It offers precisely calibrated compression ratios of 2:1, 4:1, and 10:1, further complemented by an additional 'DS' mode. Release times, including options like DS, .2, .4, .8, 1.6, and the renowned 'Auto' setting, are fixed. Automated make-up gain is integrated to streamline workflow, while a Sidechain High Pass Filter selectively processes audio.
The B-Dyn 611B also features a Stereo Link mode for enhanced stereo signal control and a novel 'classic' SSL flavour designed to imbue productions with the distinctive SSL sonic signature.
Compressor/ Limiter: Precise Control and Artful Sound Sculpting
In the domain of Compressor/Limiter operation, the module offers various controls. The RATIO control presents stepped compression ratios of 2:1, 4:1, 10:1, and 'ds'. The 'ds' setting is a fixed 10:1 ratio with an added sidechain filter. The THRESHOLD control dictates the point at which the compressor engages based on the selected ratio, providing automatic make-up gain as well. The module includes a 6dB/octave 185 Hz High Pass Filter in the compressor sidechain to minimise bass-induced pumping effects. RELEASE is switched/fixed, ranging from .2 ms to 1.6 ms, with 'DS' and 'Auto' release options. Activating DS mode modifies the attack time from approximately 30 ms to 2 ms, catering to efficient de-essing processes.
Efficient Sibilance Control with De-Ess (DS) Mode
The De-Ess (DS) mode optimizes the module for reducing sibilance. The module operates at a 10:1 ratio with a filtered S/C input signal by configuring the Compressor Ratio and Release controls to' DS'. This delivers broad-spectrum compression triggered by sibilant elements. The DS release adapts between 30 ms and 50 ms in response to the processed signal. The attack time is accelerated to 2 ms, slightly quicker than the E-Series Dynamics module's fast setting.
Versatile Gate and Expander Functionality
In the Gate/Expander capabilities realm, the B-Dyn module acts as a 20:1 Gate or a 2:1 Expander, selectable via the EXP button. With an attack time of 0.2 ms, it swiftly responds to incoming audio. The RANGE control dictates the maximum gain reduction by the Gate/Expander, with an 'out' setting bypassing this function. THRESHOLD determines the level above which the gate/expander activates, while RELEASE controls the duration of the audible signal after gate/expander closure. The EXP button transitions the gate to expander mode, featuring a gentle curve for subtle control over audio levels below the threshold.
A Legacy Redefined: Dynamics Processing in the 500 Series
The Solid State Logic B-Dyn 611B is a remarkable embodiment of the esteemed SL 4000 B console's dynamics processing prowess, encapsulated within the compact 500 Series format. This module pays homage to the console's legacy and empowers modern producers with its array of dynamic processing tools.
