Buy Used CL4 by Crown


CH Series amplifiers can directly drive ??constant voltage lines, so you can avoid the expense of adding step-up transformers fordistributed loudspeaker systems. CL Series amplifiers offer low-impedance compatibility for applications where high-power, low-impedance loads are the primary requirement. All CH and CL Series amplifiers featureCrown's exclusive SST (System Solutions Topologies) expansion system. The SST expansionsystem makes it easy to tailor your amplifier to a specific applicati...

...a specific application or to add future technology as it develops (see Section 4.3.2 for
descriptions of available SSTs).
Modern power amplifiers are sophisticated pieces of engineering capable of producing
extremely high power levels. They must be treated with respect and correctly installed if they are to provide the many years of reliable
service for which they were designed.

Amp Rack Units

Amp rack units refer to an assortment of rack-mounted or rack-protected PA amplification or sound reinforcement equipment that is set up to work with a mixer and loudspeakers. An amplifier, also called a power amplifier, is a basic signal processing unit that increases the power of an audio signal to make the sound from a human voice or music louder. A pro audio amplifier is used in professional sound systems as the last active component in the signal chain because it receives input from mixers or other signal processing units, increases the power of the signal, and sends the output to speakers. There are other types of amplifiers also referred to as amp rack units. A touring amplifier is simply a power amplifier that is designed to withstand conditions that touring musicians are exposed to especially being on the road most of the time. Live power amplifiers are used to support the audio demands of live performances. These amps make help create the unique experience of sound in live concerts. Some amp rack units are built by combining or adding amplifier modules with other parts. These are amplifier sub-units or parts designed to meet certain specifications. To have a whole amplification unit you may need a transformer, bridge rectifiers and filter capacitors, speaker connectors, input connectors, volume control, heatsink and a suitable rack mount case.
