The CL-5000 incorporates several new state-of-the-art circuit designs which make it an extremely efficient and universal dynam-
ics processor: intelligent program recognition, interactive Expander/Gate and a new Dynamic Enhancer.
IKA (Interactive Knee Adaption) Compressor
The IKA (Interactive Knee Adaption) circuitry successfully combines the traditional “Hard Knee” compressor concept with the
“Soft Knee” feature. The “Soft Knee” mode, with its “soft” control characteristics, is the basis of the “inaudible” and “musical”
compression of the program material, while the “Hard Knee” function is a prerequisite both for creative and efficient dynamics
processing and for limiting signal peaks reliably and precisely. This latter function is required to protect subsequent equipment
against distortion, and possible damage.
The Interactive AUTO Processor
The CL-5000 offers an interactive AUTO processor and intelligent program detection. In the AUTO mode, the attack and release
times are derived automatically from the program material, thus effectively eliminating common adjustment errors. This feature
enables optimum results by allowing you to heavily, yet “musically”, compress the signal’s dynamic range without any audible
“pumping”, “breathing” or other side effects.
Manually Adjustable Attack and Release Controls
The response of a compressor and the quality of dynamics processing largely depend on the control times, i.e., the attack and
release functions. When processing signals from individual instruments such as drum, guitar, etc., and when using the compres-
sor to protect the audio system against signal transients, it is imperative that the control times be user- adjustable. The CL-5000
offers this feature by providing both ATTACK and RELEASE controls to allow for variable sound processing.
IRC (Interactive Ratio Control) Expander/Gate
A common problem in using compressors is that the noise floor can be highly amplified during quiet sections or when there are
music pauses. This effect is exaggerated when the compression ratio is inappropriate.
An IRC (Interactive Ratio Control) Expander/Gate has been integrated into the CL-5000. The expansion ratio is automatically
adjusted, dependent on the program material (The response characteristics of conventional expanders tend to cut into the signal
abruptly, often resulting in unacceptably greater attenuation than desired). With the added IRC, the expander is less critical of
adjustment and more tolerant of useable signals only slightly above the noise floor.
Dynamic Enhancer
One of the most common negative effects of compression is the “dulled” or “squashed” sound that is produced when it is
applied to composite music. Since high-energy low frequency instruments cause a compressor to reduce the overall gain, any
high frequency instrument signals occurring simultaneously will also be reduced in level. This “spectral intermodulation” causes
the “squashed” sound effect.
The solution to this problem is the Dynamic Enhancer which allows for selective replacement of high-end loss accrued through
use of compression. Since the Enhancer tracks the amount of compression, enhancement will not be added when no compres-
sion is taking place. No altered sound or any additional noise. This feature allows you to apply compression throughout the mix
without any additional outboard enhancer, etc.
The following operational manual will introduce you to the CL-5000 and its various functions. AFTER READING THE MANUAL
