PL
Maintenance
A PL Series amplifier requires no routine maintenance other than occasional cleaning or replacement of the fan intake filters on the rear of the amplifier. (This operation does not require any tools). Filters must be kept clear and clean to ensure proper ventilation through the unit. If the amplifier is used in an extremely dusty or smoky environment, the filter should be cleaned or changed frequently and the unit should be peri- odically “blown free” (using compressed air) of any foreign matter that may penetrated through the filter.
Users will not need to make any internal adjustments to the amplifier during its lifetime. There are no user- serviceable parts or adjustments that require opening the power amplifier. Cover removal exposes the risk of shock, so refer all servicing to qualified service technicians authorized by Crest Audio.
User Responsibility
Your PL Series amplifier is very powerful and can be potentially dangerous to loudspeakers and operators alike. It is your responsibility to read the section titled “Important Precautions” and make sure that the amplifier is installed, wired, and operated properly as instructed in this manual. Many loudspeakers can be easily damaged or destroyed by overpowering, especially with the high power available from a bridged amplifier. Read the section on Speaker Protection and always be aware of the speaker’s continuous and peak power capabilities. Crest Audio is not responsible for damage to loudspeakers for any reason.
Service and Repair
In the unlikely event that your amplifier develops a problem, it must be returned to an authorized distributor, service center or shipped directly to our factory. To obtain service, contact your nearest Crest Audio Service Center, Distributor, Dealer, or any of the worldwide Crest Audio offices. For contact information, reach Crest Audio Inc. Customer Service directly at: TEL. 201.909.8700 (USA) Fax. 201.909.8744 (USA). Because of the complexity of the design and the risk of electrical shock, all repairs should be attempted only by qualified technical personnel. If the unit needs to be shipped back to the factory, it must be sent in its original carton. If improperly packed, your amplifier may be damaged.
