Focusrite Blue 330 Stereo Compressor #F06113T (Used)

The Focusrite Blue 330, employs a unique single-VCA circuit design, offering unrivalled precision and performance in dynamic control in a mastering suite. All rotary controls are multi-position precision switches, allowing accurate recall of previous settings. Very accurate PPMs, switchable to measure gain change, input or output level, offer dual scale operation that allows accurate measurement of a wide range of peak signals. Thanks to the broad range of the threshold
control and Focusrite’s proprietary circuitry, the Blue 330 can compress very high signal levels - up to +26dB without distortion. The Limiter too, offers an unusually wide threshold range.

The VCA used is a balanced class A design, offering superb low noise distortion and excellent common-mode rejection. In order to separate compression and limiting, the
sidechain electronics contain three VCAs to generate compression and limiting rather than the more common characteristic of compression that turns into limiting. The sidechain electronics utilise class A design techniques, ensuring superb transient response. Both compression and limiting therefore offer true peak response, not averaging RMS response and control.

The use of high quality audio Class A 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 compression is being applied.

LOOK AHEAD LIMITER
Combines a low distortion Limiter with an audio delay to allow sidechain circuits a finite time to control and limit transients accurately. Designed to protect A/D converters from fast transients, which would normally cause overload when connected through a standard limiter. Look ahead limiting allows more subtle limiting thresholds to be used while still protecting the A/D input from overload.
