Resumen del manual
also provides a gate function. • A very favorable SN ratio and low distortion are assured thanks to the superior performance VCA that was selected for this unit. As a result, there is almost no deterioration in sound quality. • The unit’s operating status and the effect of various settings can be easily confirmed by viewing the Gain Reduction Indicators. • The unit adapts readily to a wide range of applications since it is equipped with a Detector In Jack, as well as Stereo Link Jack. The former allows for the operational characteristics of the unit to change in correspondence with the signals arriving from the external source. The latter provides for the synchronization of two CL-50s. • By employing the optional RAD-50 Rack Mount Adaptor, two units can be used together as a set which fits into a 1U space in a standard 19-inch rack.

Use of any other power adaptor could result in damage, malfunction, or electric shock. Power Supply • When making any connections with other devices, always turn off the power to all equipment first; this will help prevent damage or malfunction. • Do not use this unit on the same power circuit with any device that will generate line noise, such as a motor or variable lighting system. • The power supply required for this unit is shown on its nameplate. Ensure that the line voltage of your installation meets this requirement. • Avoid damaging the power cord; do not step on it. place heavy objects on it etc. • When disconnecting the AC adaptor from the outlet. grasp the plug itself, never pull on the cord. • If the unit is to remain unused for a long period of time, unplug the power cord. Placement • Do not subject the unit to temperature extremes (eg. direct sunlight in an enclosed vehicle). Avoid using or storing the unit in dusty or humid areas or areas that are subject to high vibration levels. • Using the unit near power amplifiers (or other equipment containing large transformers) may induce hum. • This unit may interfere with radio and television reception. Do not use this unit in the vicinity of such receivers. Maintenance • For everyday cleaning wipe the unit with a soft, dry cloth (or one that has been slightly dampened with water). To remove stubborn dirt, use a mild neutral detergent. Afterwards, be sure to wipe the unit thoroughly with a soft, dry cloth. • Never use benzene, thinners, alcohol or solvents of any kind, to avoid the risk of discoloration and/ or deformation. Additional Precautions • Protect the unit from strong impact. • Do not allow objects or liquids of any kind to penetrate the unit. In the event of such an occurrence. discontinue use immediately. Contact qualified service personnel as soon as possible. • Never strike or apply strong pressure to the display. • Before using the unit in a foreign country, consult with qualified service personnel. • Should a malfunction occur (or if you suspect there is a problem) discontinue use immediately. Contact qualified service personnel as soon as possible. ■ WHAT THE CL-50 CAN DO The CL - 50 is equipped to provide the features o( three types of devices: Compressor, Limiter, and Gate. You will be able to use these features most effectively after first gaining a good understanding of how they work. < Compressor/Limiter > While both of these act in compressing the input signal, factors such as the Threshold Level. Ratio, and the intended purpose result in their differentiation. Compressor: Takes a divergent signal and compresses it. and when necessary, averages it to create sound of an amplitude that is perceived acoustically as being well-controlled. Limiter: Serves in protecting equipment from excessively powerful input, and in preventing distortion. • Threshold Level When using the Compressor/Limiter, the point at which it is to take effect is called the "Threshold Level". All signals of a level lower than the Threshold level are output without compression. • Ratio The rate of compression to be applied with respect to the input signal is known as the “Ratio”. For example, in a situation where a signal 10dB higher than a given signal is input, but at output there is only a 5 dB increase produced, there is a ratio of 10dB:5dB, or 2:1. •-'.Threshold Level and Ratio> • Attack Time The Attack Time is the length of time it takes for compression to reach its set value, from the instant the signal being input has surpassed the Threshold Level. # Release Time The Release Time is the length of time it takes for compression to be released and the signal to revert to normal, from the moment the signal drops below the Threshold Level.
