Page 5: A Introduction
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. -
Page 6: Controls, Connections, Operation
The CL-5000 is equipped with an IRC (Interactive Ratio Control) Expander, so that its expansion ratio is automatically adjusted dependent on the program material. Critical signals in the vicinity of the threshold level are processed with a minute expansion ratio, whereas signals that reduce in level will be subjected to an increasingly higher ratio, which will result in greater attenua- tion. -
Page 7: Compressor/Limiter Section (Operation)
In the CL-5000, control of the dynamics process is achieved by means of a high quality VCA (Voltage Controlled Amplifier) with an operating range of about 60 dB, i.e., the input signal level can be reduced or increased within a range of 60 dB. Input signal levels below the adjusted threshold are not reduced. - Page 8 The 12-segment GAIN REDUCTION meters indicate how effectively the gain is reduced by the compressor, within a range from 1 to 30 dB. (Note: Although the VCA of the CL-5000 features a control range of almost 60 dB, it is not useful to display the entire range, as in practice, such a broad control range will hardly ever be required.

Page 9: Dynamic Enhancer Section (Operation)
Dynamic Enhancer Section (Operation) Dynamic enhancement allows for selective replacement of high-end loss accrued through use of compression. As the signal level rises towards the threshold point where compression will occur, high frequency enhancement is added at the same degree to which the input signal is compressed. -

AC INPUT Made in China 14. INPUTS: The CL-5000 is equipped with both 1/4" (6.3mm) TRS and XLR audio input jacks. These can be used for either balanced or unbalanced operation as follows: . Unbalanced use of mono 1/4" plugs: Balanced use of TRS stereo 1/4"... -
Page 11: Applications
In this section, several typical applications of the CL-5000 are discussed. The following basic settings can resolve most dynamic problems. They are the ideal starting point. Please take the time to study the application examples carefully, in order to be able to make full use of the capabilities of your CL-5000 in the future. -

Patch the CL-5000 into a snare drum channel for example and adjust it so that triggering only occurs on snare hits. Each mic should be set to its maximum operating level, monitored and the THRESHOLD level set so the each snare hit sounds acoustically clean and separate, as though it was played on its own. -

PA and monitors, which can lead to undesired noise and feedback problems. Using the CL-5000, the mic channel can be shut off when it is not being used, reducing the possibility of noise pickup and feedback. -

4. LIMITER FUNCTION In addition to providing a variety of ways to compress signals, the CL-5000 can also be used to limit the overall output level of the unit and to protect subsequent units from signal peaks, short term overloading and over modulation (transmitters etc.). -
Page 15: Special Applications
An automatic gain control system achieves better and more constant results. Use the CL-5000 by starting with the initial settings, and use its dynamic control functions to drive either an analog or digital recording noise and distortion free up to the limit of its maximum dynamic range. -
Page 16: The Cl-5000 As A Protective Device
If you increase the average signal level by 3 dB with the CL-5000 limiter function, you effectively double the power amplifica- tion. In this way, for example, you can use a CL-5000 to convert a PA system of 5,000 Watts into a distortion-free 10,000 Watts system. -

But in many cases, this function leads more to a disturbance than to an improvement of the sound quality. If the CL-5000 is preceding this system, the signal peaks can be eliminated before they reach the limiters of he processing system. -

5.1 Reshaping Sampled Sounds With the help of the CL-5000, existing or new sampled sounds can be brightened up, changed or used to create new sound. The attack times and the dynamics of the sounds can be changed as desired. -
Page 19: External Sidechain Applications
When de-essing, simply insert an equalizer, not into the audio path, but into the sidechain path of the CL-5000. The equalizer is inserted between the audio input and the DETECTOR LOOP input of the CL-5000 . The equalizer is now inserted into the sidechain loop and controls the unit. -
Page 20: Frequency Selective Filtering Of Unwanted Signals
Take care to decrease the amplitudes of the frequencies you are trying to eliminate. Proceed now as described in the previous section E 2.1 “The CL-5000 As A De-Esser”. This will result in compression of the selected frequencies and thus a decrease in the gain of these frequencies in the program mate 2.3 Suppressing Instruments During Recording... -

2.4 Emphasizing Musical Instruments During Recording Conversely, you can use the CL-5000 to bring out an instrument solo or a lead vocal in a cluttered mix. Match the frequencies of the equalizer to the frequencies of the instruments to be emphasized (it is best to use a notch filter with a high slope). (Note: In this application, make sure you only reduce the amplitude of the selected frequencies.) The compression results in a subjective... -
Page 22: Anticipated Compression
If you feed the audio signal directly into the DETECTOR LOOP input and send the audio signal through a delay before the audio input, the CL-5000 can anticipate the need for gain change. With experimentation, the effect can create a “zero” attack time at a given frequency. -
