User manual ELECTRO-VOICE CP2200

[. . . ] Protect the power cord from being walked on or pinched particularly at plugs, convenience receptacles, and the point where they exit the apparatus. Unplug this apparatus during lightning storms or when unused for long periods of time. CAUTION: These servicing instructions are for use by qualified personnel only. To reduce the risk of electric shock, do not perform any servicing other than that ontained in the Operating Instructions unless you are qualified to do so. [. . . ] In normal operation, all CP-Series power amps are capable of driving loads as low as 2ohms. in MonoBridged mode the allowable minimum load is 4ohms. This owner's manual outlines and explains several other features of your CP-Series power amplifier. Please, make sure to carefully read all of it and mind the instructions. Carefully open t he packaging and take out the power amplifier. Next to the power amplifier itself, the package also includes this owner's manual, a mains cord and the warranty certificate. Keep the original invoice, which states the purchase/delivery date together with the warranty certificate at a safe place. Generally, installing or mounting power amps should be carried out in a way that guarantees continuously unopposed front-to-rear air circulation. Installation of appliances with opposite air circulation within one cabinet or closed rack shelf system is not recommended. When including an appliance in a closed cabinet or rack shelf system make sure to provide sufficient ventilation. Leave a gap of at least 60mm x 330mm (up to the cabinet's top ventilation louvers) for air circulation between the rear of the power amplifier and the cabinet's/rack's rear inner wall. Make sure to leave at least 100mm of space above the cabinet or rack shelf system. Since temperatures inside of the cabinet or rack shelf system can easily rise up to 40°C during operation, bearing in mind the maximally allowable environmental temperature during operation for all other appliances installed in the same rack shelf system is mandatory (also refer to "MAINS OPERATION AND RESULTING TEMPERATURE"). caution: For trouble-free operation exceeding the maximally allowable environmental temperature of +40°C is not permissible. The use of installation rails or optionally available "rear-rack-mount" rails is strongly recommended when installing the appliance in a rack shelf system or cabinet to prevent the front panel from bending. The power amplifier has to be protected against: dripping or splashing water, direct sunlight, high temperatures or direct influence of heat sources, high humidity, extensive dust and vibrations. Condensation on internal parts may occur when transporting the power amplifier from a cold into a warmer environment. In that case operation is only permissible after the appliance has gained the new temperature (after approximately one hour). If foreign objects or liquids have entered the power amplifier's enclosure make sure to instantly separate the appliance from the mains power and contact an authorised service centre for inspection before continuing operation. Use the POWER switch, located on the front panel's, right side to switch the appliance's power on. The soft-start function limits against current inrush peaks on the mains, which in addition prevents the mains line protection switch from activating during power-on. The loudspeaker outputs are activated via relay switching with a delay of approximately 2 seconds to efficiently attenuate eventual power-on noise. [. . . ] While the amplifier of channel A operates as usual, the audio signal is internally inverted and routed to the amplifier of channel B. The amount of heat resulting from power dissipation might remain inside of a rack-shelf and needs to be diverted using appropriate measures. The following table is meant as auxiliary means for calculating temperatures inside of a rack-shelf system/cabinet and the ventilation efforts necessary. The column , , Pd" lists the leakage power in relation to different operational states. [. . . ]
