IMPORT ANT 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.
6. Clean only with a damp cloth.
7. Do not block any of the ventilation openings.
Install in accordance with the manufactures instructions.
8. Do not install near any heat sources such as radiators, heat registers, stoves, or other apparatus 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.
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 mains separator transformer is mandatory during maintenance while the appliance is opened, needs
to be operated and is connected to the mains
3. Switch off the power before retrofitting any extensions, changing the mains voltage or the output voltage.
4. The minimum distance between parts carrying mains voltage and any accessible metal piece (metal
enclosure), respectively between the mains poles has to be 3 mm and needs to be minded at all times.
The minimum distance between parts carrying mains voltage and any switches or breakers that are not
connected to the mains (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.

Thank you for choosing Electro-Voice® SxA active powered loudspeaker systems.
These systems are the culmination of EV’s 75 years of experience in transducer
design and over 50 years of experience in designing and building electronics.
Please take time to consult this manual so that you can understand all the
features built into your EV systems and fully utilize all their performance
capabilities.

Safety First
When setting up, installing and using Electro-Voice® SxA speaker systems, there are a
number of precautions that you should follow:
When Electro-Voice® SxA speakers are used for portable applications in which they will be
·
stacked directly on the floor or mounted on a tripod stand, make sure that the floor or
stage is solid and secure.
Electro-Voice® SxA speaker systems include 1 3/8-inch stand mounts to allow mounting on
·
tripod stands.
Make sure to:
Check the specifications of the speaker stand to be certain it is capable of supporting the
·
weight of the speaker.
Check that the speaker stand is placed on a flat, stable surface and be sure to fully extend
·
the legs of the stand. Do not try to make the stand “taller” and compromise its structural
integrity.
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.
Do not attempt to suspend more than one speaker on a stand designed for a single
·
speaker.
Unless you are confident that you can safely handle lifting the weight of the speaker onto
·
the stand, ask another person to help you place it.
After the system is in operation for a few minutes, the heat sink will become warm to the
·
touch and can become quite hot after extended high-level operation. Avoid touching the
heat sink fins to prevent burns. When installing the system, use care to ensure that there
is at least two inches of space behind the heatsink to allow free circulation of air.
If you intended to hang or fly the SxA two-way systems, please 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
speakers be suspended taking into account all current national, federal, state and local
regulations. It is the responsibility of the installer to ensure that SxA speakers are safely
installed in accordance with all such regulations. If SxA 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. Please consult our
manual entitled Suspending System 200 Loudspeakers, and the SK1 data sheet, which details
the various hardware kits that are available to safely suspend SxA speakers and how each kit
should be used. There are also data sheets for each EV hanging hardware part that should
also be consulted prior to suspending speakers.
®
strongly recommends that SxA
®
Electro-Voice® does not recommend use of SxA speakers outdoors or in high
·
moisture environments. Avoid exposing SxA speakers to direct moisture and or
high humidity that can cause corrosion of electrical contacts and problems with
loudspeaker cones and surrounds.
Electro-Voice® SxA 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

Description
Electro-Voice® SxA
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. They retain
typical EV ruggedness, reliability and impeccable sound quality.
System Features – S
Integrated mixer/crossover/amplifiers/speaker system with separate mic and line inputs,
·
EQ and line-level outputs.
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 150 watts continuous average power and 350
·
watts dynamic power (IHF A). Dynamic output power is important because it determines
the transient capability of the system.
The high-frequency power amplifier delivers 50 watts continuous average power and 80
·
watts dynamic power (IHF A). This provides more than 3 dB of headroom over the
continuous current capabilities of the high-frequency driver.
The line input utilizes Neutrik “combo” connectors, which will accept either ¼-inch or 3-
·
pin XLR-type connectors.
The mic input is balanced, low-impedance 3-pin XLR-type
·
The separate line output is 3-pin XLR-type balanced, low-impedance output that can be
·
used with long cable runs.
