Every professional recording session revolves around dynamics management, from subtle regulations to the most creative alterations. We thus designed the Dynamics 2806 to be a reliable tool during any of these processes: it is meant to fit your workflow, complement your gear, and help you achieve your sound without wasting time.

The Dynamics 2806 is a single-VCA mono expander and compressor for the 500-series format. We designed it to handle a wide dynamic gamut in the most straightforward way.
The compressor reduces the gain when the sound is above a given threshold (thus reducing the dynamic range); the expander reduces the gain when a signal is below a given threshold (thus expanding the dynamic range).
The expander and compressor are independent. In both circuits, the signal feeds a filter set and then an envelope follower (rectifier). The resulting control voltage feeds two integrators (time constants) that generate two independent sidechains, both working over the VCA level.
The Dynamics 2806’s circuit is light and straightforward, but a few switches in the right spots can dramatically change its behavior, making it suitable for creative compression, transient shaping, de-essing, sidechaining, parallel processing, and any other task that may pop up in the studio.
Single VCA and Straightforward Signal Path
We designed an articulated device capable of complex dynamic processing with a single VCA stage. As a result, we minimized the possible causes of sound deterioration and kept the architecture light and responsive.
Feed-Forward Expander and Feedback Compressor (With a Twist)
The expander sidechain monitors the VCA input signal (feed-forward), while the compressor sidechain monitors the VCA output (feedback). However, a switch selects if the feedback point is pre- or post-makeup, for even more control over the makeup gain.
The Dynamics 2806 can compress and expand at the same time. The Priority switch adds another degree of control: when pushed, the expander works exclusively when the compressor is not reducing the signal’s gain.
Adaptive Analog Sidechains
A significant component of a signal’s dynamics is its energy distribution over time. For this purpose, we finely calibrated Dynamics 2806 to react to the incoming sound according to its articulation: faster with fast sources, slower with slow ones.
Two Compressor Time Constants for Subtle or Creative Uses
Sometimes one needs surgical precision to manage a sound’s amplitude non-destructively; other times, one needs a more creative compression to add peculiar dynamic effects. Dynamics 2806 uses two different time constants sets: by default is sharp and precise but can add harmonic distortion if used recklessly; The Classic mode, on the other hand, can add some noticeable artifacts (the “pumping” sound) but with less harmonic distortion.
Filtered Internal and External Sidechain (That You Can Listen)
A versatile sidechain circuit accepts a second input that can drive the compressor or the expander. It can also be summed to the internal sidechain when routed to the compressor.
The sound is always filtered before both sections, whether the Dynamics 2806 works with an internal or external sidechain. The expander has a low-pass and a high-pass filter, while the Contour has a precise shelf control that attenuates the low end and emphasizes the high end.
The Listen switch allows you to monitor the sidechain sound of either the compressor or expander for precise filtering.
Two Bypass Modes
When switching the Dynamics 2806 off, it is possible to choose between a hard bypass mode, where a relay routes the input straight to the output, or an off mode, where the sound still passes through the circuit with no active modulation. This last option allows you to retain the VCA color.
Reliability and Easy Maintenance over Time
We refuse the idea of obsolescence, and we want our products to be the lifelong partners of every professional audio engineer. Dynamics 2806’s design allows for easy maintenance and reliability over time through careful choices in terms of design, assembly, and individual components.
Unconventional, Discrete-Buffered Output Stage
After choosing a Lundahl LL1585, one of the best output transformers available today, we designed an audiophile-grade discrete output current stage to feed the transformer with the most pristine sound possible.
Following our philosophy of simplicity, we avoided signal deterioration by removing unnecessary decoupling capacitors. Instead, we placed high-end capacitors on inputs and insert outputs to prevent damage followed by incorrect connections (e.g., phantom power) or defective sources with DC offset.
Active Filter on Power Source
We used active filter stages on every section to guarantee the best performance regardless of their application environment.
