ELECTRO-VOICE ® Plasma Owner’s Manual 4
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 high-
quality 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 XLR-
type connectors.
· The separate line output is a 3-pin XLR-type that can be used to connect additional systems.
· 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. Turn on the power switch
and ensure that the system is receiving power by monitoring the status LED. If the system is
receiving signal, the LED will illuminate green.
