Introduction

Congratulations on your purchase of this API 500 series compatible SSL B Series Dynamics module.

This module has been specifically designed to operate in an API 500 series rack such as the API lunchbox® or equivalent. In common with many such modules, the nominal input/output level is +4dBu.

The SSL B-DYN 500 Series module comprises a compressor/limiter and an expander/gate, the design of which returns faithfully to the circuit and key components which defined the sound of the earliest SSL B Series channel strip.

The Dynamics Section in the 4000 B-series console channel strip was unlike any other SSL channel dynamics modules (4000 E-series, 9000- series etc.). It had a design more similar to the topology of the SSL Bus Compressor. The compressor features three fixed ratios, 2:1, 4:1 & 10:1 with an additional ‘ds’ mode.

The circuitry and reponse of the B-DYN module uses the latest component technology and is modelled on the original circuit design of the SSL 4000 B-Series channel strip as Installed in the 80s in ‘The Stone Room’ at Virgin’s Townhouse Studio (London), Le Studio (Montreal) and Record Plant (LA)

Operation

Please refer to the illustration opposite.

The IN button , located bottom right, switches the entire module in and out of circuit.

The two vertical columns of LEDs , located top left, provide an indication of dynamics activity. The row of green LEDs to the right show Gate/Expander activity whilst those to the left indicate operation of the Compressor/Limiter.

Compressor/Limiter

RATIO: Stepped compression ratios 2:1, 4:1, 10:1 and ‘DS’. The ‘DS’ setting is a fixed 10:1 with an additional 12db/Oct high pass sidechain filter at approx. 7 kHz. When ‘out, the compressor is bypassed

THRESH: Whenever a signal exceeds the level set by this control, the compressor will start to act at the ratio set by the RATIO control. The THRESHold and RATIO controls also provide automatic make-up gain. A small improvement to the linearity of this control has been made in the module over the original channel strip control. This helps with Threshold tuning using this smaller scale 500 series knobs.

HPF: 6 dB/Oct High Pass Filter at 185 Hz in the Compressor sidechain to help reduce bass pumping effects

RELEASE: Switched/fixed release ranges from 0.2 s to 1.6 s with additional ‘DS’ & AUTO release options.

Attack Time is approx. 30ms (2ms in DS mode) How to use the SL 4000 B de-esser (DS) mode

Set the COMPRESSOR RATIO and RELEASE controls to ‘DS’. The de-ess ratio is a 10:1 ratio with 7 kHz filtered S/C input signal, delivering broadband compression triggered by sibilance. The ‘DS’ release is variable in accordance to the signal between 30 & 50 ms. This is a much faster minimum release than you would normally expect from an SSL Dynamics section. Also Attack time changes to 2 ms in DS mode.

COMPRESSOR RATIO & RELEASE in ‘DS’ work independently of each other & can be utilised in very creative ways. E.g you can use the fast ‘DS’ attack/release without using the ‘DS’ ratio, for aggressive compression.

Gate/Expander

This section can act as a 20:1 Gate or as a 2:1 Expander when the EXP button is pressed.

RANGE: Controls the maximum amount of gain reduction applied by the gate/expander. When set to ‘out’, the gate/expander is bypassed

THRESH: Sets the threshold above which the the gate/ expander will be opened.

RELEASE: Sets how long the signal remains audible after the gate/expander closes. Fixed settings of 0.1, 0.2, 0.4, 0.8 and 1.6 Seconds.

EXP: Switches the gate to expander mode with a gentle curve, for subtler control of level below the threshold.

Attack Time is approx. 0.2 ms

LINK

This button switches the dynamics sidechain to be linked/summed if a link connection is implemented between a pair of modules. This is an optional feature of the back-plane of some 500 series compatible racks. ‘LINKing’ allows adjacant dynamics modules to act as a stereo pair. The effect of the LINK sidechan sum means that the dynamics module that is changing gain the most applies the same gain to its paired module. This prevents image shifts with stereo signals with dynamic stereo/panned content.
