Important Safety Instructions
The lightning flash with arrowhead symbol, within an equilateral triangle
is intended to alert the user to the presence of uninsulated “dangerous
voltage” within the product’s enclosure that may be of sufficient
magnitude to constitute a risk of electric shock to persons.
The exclamation point within an equilateral triangle is intended to alert
the user to the presence of important operating and maintenance
(servicing) instructions in the literature accompanying the appliance.
1. Read these instructions.
2. Keep these instructions.
3. Heed all warnings.
4. Follow all instructions.
5. Do not use this apparatus near water. Do not expose this apparatus to dripping or splashing and ensure that no objects filled

6. Clean only with a dry cloth.
7. Do not block any of the ventilation openings. Install in accordance with the manufacturers instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus (including amplifiers)
that produce heat.
9. Only use attachments/accessories specified by the manufacturer.
10. Refer all servicing to qualified service personnel. Servicing is required when the apparatus has been damaged in any
way, such as power-supply cord or plug is damaged, liquid has been spilled or objects have fallen into the apparatus,
the apparatus has been exposed to rain or moisture, does not operate normally, or has been dropped.
11.To completely disconnect AC power from this apparatus, the power supply cord must be unplugged.
For US and CANADA only:
Do not defeat the safety purpose of the grounding-type plug. A grounding type plug has two blades and a third grounding prong.
The wide blade or the third prong are provided for your safety. When the provided plug does not fit into your outlet, consult an
electrican for replacement of the absolete outlet.
Important Service Instructions
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 contained in the Operating Instructions unless you are qualified to do so. Refer
all servicing to qualified service personnel.
1. Security regulations as stated in the EN 60065 (VDE 0860 / IEC 65) and the CSA E65 - 94 have to be obeyed when
servicing the appliance.
2. Use of a AC separator transformer is mandatory during maintenance while the appliance is opened, needs to be
operated and is connected to the AC.
3. Switch off the power before retrofitting any extensions, changing the AC voltage or the output voltage.
4. 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.
5. Replacing special components that are marked in the circuit diagram using the security symbol (Note) is only permissible
when using original parts.
6. Altering the circuitry without prior consent or advice is not legitimate.
7. Any work security regulations that are applicable at the location where the appliance is being serviced have to be strictly
obeyed. This applies also to any regulations about the work place itself.
8. All instructions concerning the handling of MOS - circuits have to be observed.
Note: SAFETY COMPONENT (HAS TO BE REPLACED WITH ORIGINAL PART ONLY)

Safety First
When setting up, installing and using Electro-Voice® Plasma speaker systems, there are a number
of precautions that you should follow:
· When Electro-Voice® Plasma speakers are used for portable applications in which they will be
stacked directly on the floor, make sure that the floor or stage is solid and secure.
Make sure to:
· Route cables and position the stand so that performers, production crew and audience members
will not trip over the stand or cables and pull the speaker system over. Secure cables with wire
ties or tape whenever possible.
· If you intend to hang or fly the Plasma two-way systems, only do so safely with the correct
hardware and accessories.
WARNING:
Suspending any object is potentially dangerous and should only be
attempted by individuals who have a thorough knowledge of the techniques and
regulations of rigging objects overhead. Electro-Voice® strongly recommends that
Plasma speakers be suspended taking into account all current national, federal, state
and local regulations. It is the responsibility of the installer to ensure that Plasma speakers are
safely installed in accordance with all such regulations. If Plasma speakers are suspended,
Electro-Voice® strongly recommends that the system be inspected at least once a year. If any sign
of weakness or damage is detected, remedial action should be taken immediately.
There are data
sheets for each EV hanging hardware part that should also be consulted prior to suspending
speakers.
· Electro-Voice® does not recommend use of Plasma speakers outdoors without
protection from rain or in high moisture environments.
· Electro-Voice® Plasma loudspeakers are easily capable of generating sound
pressure levels sufficient to cause permanent hearing damage to anyone within
normal coverage distance. Caution should be taken to avoid prolonged exposure to
sound pressure levels exceeding 90 dB.

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 XLR-
type 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. 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.
