The Award Nominated, 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 level.
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.
