    An equilateral triangle enclosing a lightning flash/arrow- head symbol is intended to alert the user to the pres- ence of uninsulated “dangerous voltage” within the product’s enclosure, which may be of sufficient magni- tude to constitute a risk of electric shock. An equilateral triangle enclosing a...

    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 a...

    1. Power switch: this switches the ac power on or off. Note: in order to avoid possible undesired noise transients in a live sound reinforcement application, switch on the power to your cl-5000 before switching on the amplification system. Expander/gate section (operation) audio, in general, is only...

    Compressor/limiter section (operation) by measuring the dynamic range of musical instruments in live recording situations, you will find that extreme amplitudes will occur which can lead to overload in subsequent signal processing equipment. In most application, these signal peaks can lead to heavy ...

    4. Threshold controls: the threshold controls set the threshold point for the compressor sections. They have a range of -40 to +20 db. 5. Ratio controls: the ratio controls determine the ratio between the input and output level for all signals exceeding the threshold point. The control range can be ...

    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...

    1.1 compression/leveling/limiting/clipping now that the functions and operation of the individual sections and their controls have been explained, we would like to ac- quaint you with more of the terms and relationships of the dynamics process. Compression a compressor converts a large dynamic level...

    2. Expander/gate section the main task of the expander/gate is to “inaudibly” eliminate undesirable background noise from the usable signal. This assumes that there is a slight level difference between the usable signal and noise floor, in order to be able to define the operat- ing threshold of the ...

    2.3 reducing leakage in stage mics the cl-5000 has many uses in live sound re-enforcement, on stage and in multi-miking situations: a well set up expander/gate can effectively suppress background noise, compressor type pumping noise and microphone leakage etc., without producing any undesirable side...

The auto function of the attack and release times provides program dependent dynamic processing which suits most standard uses. If a ...

    1. Using the cl-5000 for recording and cassete duplication in the recording and duplication field, the goal should always be to achieve an optimum recording level onto the recording media. Too low or too high recording levels lead to side effects such as noise, distortion, etc. In mastering and mult...

    2. The cl-5000 as a protective device sound system distortion is usually a result of amplifiers and loudspeakers being driven beyond their limitations by signals clipping. This can lead to unpleasant distortion that is dangerous to the speakers. During normal operation a speaker diaphragm is require...

    2.3 improving the sound of a “processed” system for our purposes here, let’s define a “processed” system as a pa system with a special active crossover whose outputs are linked via separate power amplifiers to the loudspeakers. Each band has its own limiter whose task it is to limit dangerous signal...

    3. Using the cl-5000 with tape recorders the cl-5000 can be used to prevent saturation of magnetic tape and to improve the signal-to-noise ratio of the tape machine. In professional recording studios, the saturation level of the tape, system headroom and the output level of the console are all known...

    External sidechain applications 1. The detector loop connector the cl-5000 offers exceptionally versatile external control by using the detector loop connector. By using this external control input, the cl-5000 control path is disconnected from the audio input and therefore interrupted . The audio i...

    3. 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. ...
