The CharterOak SCL-1 Discrete Compressor Limiter will provide a
constant output level regardless of input level or frequency, without
the familiar pumping and gasping effect that is inherent in most
compressors and limiters.
This can be attributed to the design of the circuit, which combines
the features of waveform differentiation and integration. This allows
for fast attack times without overcompensation and a release
characteristic that is a function of dynamic range and average program
The device achieves this by employing a rectifier circuit that
possesses a parabolic average charge curve. The end result of the
circuit is a quick release that releases to a continually changing
average level, which is determined by the parabolic charge curve of the
The CharterOak SCL-1 circuit design is straight forward, and employs
NO MAGIC BLACK BOXES OR OTHER WALLET SHRINKING COMPONENTS. All of the
components used in the design of the CharterOak SCL-1 are readily
available items and are employed in a manner so as to provide plenty of
headroom for years of reliable operation.
The CharterOak SCL-1 is designed to fit any standard 19" rack. The
unit may be used as a stereo unit, or as two independent limiters in
the dual mode. This feature enables the end user to employ the device
in one or two track production applications.
Do not be afraid to drive the limiter, even with classical music formats. It WILL NOT pump or gasp.
The processor is delivered with a lifetime warranty on all parts and labor and easy access to factory technical support.
