Focusrite Red 3 Dual Channel Compressor

The best thing professional engineers say about the Red 3 Dual Channel Compressor is "I know we used it but it doesn't sound like we used it". The Red 3 is another legendary Focusrite piece that has a very transparent sound due to its top-of-the-line VCA components and Class A architecture.

The Red 3 employs an unusual and original single-VCA design to achieve high quality and truly independent compression and limiting, without the compromise and unnecessary processing involved in traditional designs. The success of the design is attested to by the Red 3's TEC award for Outstanding Technical Achievement in the Signal Processing Technology category.

The VCA used is a proprietary Focusrite design, fully discrete and balanced, offering superb low noise and distortion, and excellent common-mode rejection. In order to separate compression and limiting, the side-chain electronics contain three VCAs in series to generate compression and limiting control voltages which drive the main VCA. The result is true compression followed by limiting, rather than the more common characteristic of compression that turns into limiting. The sidechain electronics are class A, ensuring superb transient response. Both compression and limiting therefore, offer true peak response, not averaging RMS response.

The use of such a high quality audio VCA as the only element between input and output means a very short signal path, and an ability to retain a natural, unobtrusive sound even when significant… read more compression is being applied.

Each channel has clear and identical controls, for compressor ratio, threshold, make-up gain, attack and release, and limiter threshold. A program-dependent auto-release mode is available, and the VU meters can be switched to show levels in two ranges, or gain change. In stereo mode the lower set takes control of both channels.
