User manual ELECTRO-VOICE PLASMA

[. . . ] The minimum distance between parts carrying AC voltage and any accessible metal piece (metal enclosure), respectively between the AC poles has to be 3 mm and needs to be minded at all times. The minimum distance between parts carrying AC voltage and any switches or breakers that are not connected to the AC (secondary parts) has to be 6 mm and needs to be minded at all times. Replacing special components that are marked in the circuit diagram using the security symbol (Note) is only permissible when using original parts. Altering the circuitry without prior consent or advice is not legitimate. [. . . ] Caution should be taken to avoid prolonged exposure to sound pressure levels exceeding 90 dB. 3 ELECTRO-VOICE® Plasma Owners Manual Description Electro-Voice® Plasma high powered loudspeakers are fully integrated audio systems with carefully matched electronics and transducers. These products make it easy to setup a highquality sound system quickly with a minimum of cables and external electronics. It retains typical EV ruggedness, reliability and impeccable sound quality. System Features - Plasma · Two built-in power amplifiers, one for low frequencies and one for high frequencies. The amplifiers also contain electronic crossover circuitry and CD horn compensation optimized for the speaker components a well as a limiter circuit that prevents either amplifier from clipping while preserving the sonic quality. · The low-frequency power amplifier delivers 500 watts continuous average power. · The high-frequency power amplifier delivers 150 watts continuous average power. · The subwoofer power amplifier delivers 800 watts continuous average power. · The line input utilizes Neutrik "combo" connectors, which will accept either ¼-inch or 3-pin XLRtype connectors. · The separate line output is 3-pin XLR-type balanced, low-impedance output that can be used with long cable runs. · The Plasma P1 two-way system is perfect for use as powered floor monitors. · Neutrik Powercon connectors are used for AC power connections. They provide a positive locking feature to prevent accidental disconnection. System Setup To get your Plasma system into operation as quickly as possible, please observe the following steps and precautions. · Plug the 3-terminal Powercon ac cable into a grounded line receptacle. Extension cords can be used to lengthen the ac cable as necessary but make sure that they are 3-conductor 14 gauge or greater, and that are properly grounded to avoid electrical hazards and extraneous noise. · Be sure that the Plasma system is plugged into an ac power source that is capable of supplying the correct voltage. If the line voltage drops too much, the built-in amplifiers won't be able to develop their rated power and sound quality will suffer. Under high signal conditions, the Plasma amplifier section can pull 3 ­ 4 amps of current (120 volt models) (2 amps at 240 volts). That means that no more than 4-Plasma systems should be plugged into a single 15 amp electrical service. Be cautious of what else is plugged into the same electrical service line to avoid electrical problems and poor performance. · BEFORE TURNING THE POWER ON, MAKE SURE THAT THE LEVEL CONTROLS ARE DOWN TO AVOID TRANSIENTS OR UNEXPECTED LOUD SOUND. [. . . ] Prior to each use, inspect the loudspeaker enclosures for any cracks, deformations, missing or damaged components, which could reduce enclosure strength. Inspect the track and bracket assembly on the enclosures for any cracks, deformations, missing or loose screws which could reduce the flying hardware strength. Never exceed the limitations or maximum recommended load for the Plasma systems. 9 ELECTRO-VOICE® Plasma Owners Manual Specifications Plasma P1 Freq.
