SCA B16-500 Series Compressor Module
This is the 500 series module only! It will not work in any of the SCA chassis! There is an SCA only version of the B16 available as well in the Classic series section. The 500 Series kits require voltage measurement and calibration which can be easier with the use of a 500 series extender kit.

The SCA B16 is a basic VCA compressor designed around the powerful THAT Corporation 4305(updated 4301) dynamics processor IC. It shares the basic features and familiar controls of popular VCA compressors such as the dbx 160, but includes features especially useful for tracking and mixing. First, the relay-switched 6dB pad allows the module to accommodate signals up to +30dBu without clipping. Second, the mix control enables the user to balance compressed and uncompressed signals without using an extra effects return or mixer channel. State of the art line receiver and driver ICs along with Burr-Brown op-amps provide a pristine signal path, and the board can accommodate any of three optional output transformers. Despite its power and features, the B16 has relatively few components and is fairly easy to assemble.
The transformer is OPTIONAL and is an additional $35.
There is one VERY fine pitch surface mount part. There is a purchase option to have this soldered by SCA for $10, if you do not feel comfortable soldering this part!
Input Pad and Bypass
Relay switched 6dB pad and direct bypass
Switchable Hard / Soft Knee
Soft knee for unobtrusive gain reduction or hard knee for aggressive limiting.
Combine direct and compressed signals without an effects return or mixer channel
Wide Control Range
Makeup Gain: +/-24dB
Threshold: -40dBu to +20dBu
Ratio: 1:1 to infinite
Optional Output Transformer
Install the same output transformers used on our very popular A12 preamp module. Solve isolation problems or just add transformer coloration to the signal.
CMOQ-2S - 100% Steel laminations for maximum "color".
CMOQ-2L - 50/50 Steel/high-nickel laminations, maximum versatility.
CMOQ-2H - 100% High-nickel laminations for maximum accuracy.
The 2S, 2L and 2H are an additional $35, $45 and $65 respectively and 2L or 2H WILL increase order shipping timeframe. Please email first if you would like to order a 2L or 2H transformer!
Program dependent attack and release
Non-linear capacitor circuit adapts timing according to the speed and level of signal transients.
High Quality Components
Bourns concentric potentiometers, E-Switch sealed toggle switches, and Neutrik connectors will provide years of service.
