Solid State Logic 729719X2 E-Series Dynamics Module for API 500 Series Rack

Classic SSL 4000E Console Dynamics in a 500 Series Module
The Solid State Logic E-Series Dynamics Mk2 brings the legendary sound of the SSL 4000E console’s dynamics section into a compact 500 Series format. This module delivers the same powerful compression, limiting, expansion, and gating found on the classic SL 611E channel strip, offering professional engineers the sought-after SSL tone for tracking, mixing, and mastering. Designed with precision circuit replication, this module ensures that every nuance of the original dynamics processor is faithfully reproduced.

Versatile Compressor and Limiter for Precision Control
The compressor/limiter section of the E-Series Dynamics Mk2 provides flexible ratio control, ranging from subtle compression to aggressive limiting. With an adjustable threshold from +4 dBu to -26 dBu, this module ensures optimal dynamic shaping for a variety of sources. The release control allows fine-tuning between 0.1 and 4 seconds, while the selectable hard-knee and soft-knee compression modes enable users to tailor the response to fit any mix. The fast attack option further enhances responsiveness, making it ideal for controlling transients on drums, vocals, and instruments.

Expander and Gate for Noise Reduction and Dynamic Shaping
The expander/gate section offers precise control over signal clarity by allowing users to eliminate unwanted background noise or shape the dynamic response of percussive sounds. The threshold control ranges from +4 dBu to -26 dBu, with a selectable ratio between a gentle 2:1 expansion and a strict 20:1 gate. A variable hysteresis circuit ensures natural decay, preserving the musicality of signals as they drop below the threshold. The fast attack mode further refines transient response, making this module an essential tool for drums, guitars, and vocals.

True RMS Converter for Smooth and Accurate Processing
SSL’s proprietary true RMS converter ensures that the E-Series Dynamics Mk2 reacts naturally to input levels, preserving dynamic integrity without introducing unwanted artifacts. This feature provides precise level detection, allowing the compressor and expander/gate to respond smoothly to incoming signals. Whether used for subtle dynamic control or aggressive shaping, this module maintains the natural character of your audio.

Five-Segment LED Metering for Real-Time Feedback
Designed for professional workflow efficiency, the E-Series Dynamics Mk2 includes a five-segment LED meter that clearly displays gain reduction and expansion/gate activity. The compressor/limiter activity is indicated in red and yellow, while the expander/gate section is displayed in green. This visual feedback allows engineers to make precise adjustments with confidence, ensuring optimal dynamic control at all times.

Authentic SSL Circuitry for Legendary Sound
Built with the same circuitry found in the original SL 4000E console, the E-Series Dynamics Mk2 faithfully replicates the sound and behavior of the SSL 611E channel strip. The gain element is designed to match the original Class A VCA chip, delivering the punchy, musical compression that SSL is known for. Whether used in tracking, mixing, or mastering applications, this module provides the unmistakable SSL sound that has shaped countless hit records.

Seamless Integration with 500 Series Racks
Designed for compatibility with API 500 Series lunchbox racks, the E-Series Dynamics Mk2 easily integrates into professional studio setups. Its compact form factor makes it a perfect addition to modular mixing and recording environments, allowing engineers to build a customized SSL channel strip with other 500 Series modules.
