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

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

To get your
and precautions (see Figures 3-7)
Plug the 3-terminal IEC 16-gauge 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
·
the correct voltage. If the line voltage drops too much, the built-in amplifiers won’t be able to
develop
the SxA amplifier section can pull 2 – 4 amps of current (120 volt models) (1 – 2 amps at
240 volts). That means that no more than 4-SxA 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
to the left of the switch above the EQ controls. If the system is receiving power, the LED
will illuminate green.
SxA loudspeakers have narrower coverage than other compact loudspeaker systems. Their
·
narrower coverage will help you avoid room acoustics problems by delivering the sound
where the speaker is aimed. You will find that precisely aiming the speakers at the
audience area away from walls will give you better sound quality.

To use the SxA two-way system for various applications:
Plug a microphone into the microphone input connector (See Figure 3). It will only accept
·
low-impedance dynamic microphones terminated with a standard 3-pin XLR-type
connector. Turn the gain control clockwise until the signal present LED stays on with the
input signal at normal operational level. Adjust the master gain control to the desired
overall output level.
Plug a line input into either the ¼-inch or the 3-pin XLR-type input connector. Examples
·
of line input sources are mixer outputs, CD/DVD players, cassette decks, VCRs,
electronic keyboards, computer sound cards, etc. The ¼- inch input is in the center of the
XLR connector and can accept unbalanced or balanced lines (TRS ¼-inch). The line input
level required to drive the unit to full power is from – 12 dBu to 0 dBu. The system’s
master gain control regulates the overall output level of the system.

If you are using the SxA two-way system with a microphone and a line input
·
simultaneously, it is simple to balance the two signals. The microphone level control has
enough gain and range so that it is possible to mix the mic input and the line input. Once
the balance between the line and mic inputs is set, simply turn the Gain Master control to
the desired level.
If there is no sound, keep the overall system gain at a reduced level until you determine
·
what the problem may be. Typically, a mixer mute switch may be engaged or a
microphone that is switched off is the source of the problem. Keeping the system gain at a
low level will allow you to troubleshoot the problem and let you hear the results without
unexpected bursts of sound or howling feedback. Start with the low-frequency and highfrequency EQ controls set in the flat position (12 o’clock, middle position) and listen to
your program material before making any changes. Be aware that boosting EQ requires
additional amplifier power and may reduce the acoustic output potential of the system
somewhat. Use EQ judiciously.
To route the signal to additional SxA systems, simply hook an XLR-type cable from the line
·
output connector on the source system to the line input connector on each additional SxA
system. The signal can be cascaded into a large number of SxA systems without
degradation.
When turning your system off, turn off the SxA systems first. This will prevent any turn-
·
off transients from other pieces of equipment from being amplified.

If you are using the SxA180 with an SxA two-way system, you will want to use the high-
·
pass output to run the signal from the SxA180 to the two-way (See Figure 5). Using the
filtered output will insure that the SxA180 only is reproducing low bass information which
will let the two-way system sound cleaner and play louder. The unfiltered output is the
best way to parallel the signal to other SxA180s or if you want more mid-bass output from
the speaker setup.

After you have confirmed that the signal is present, adjust the level control and the
·
crossover frequency. The selection of a crossover frequency will depend on room acoustics
and your particular sonic taste. In general, a lower crossover frequency will result in a
more linear, “hi-fi” sound and a higher crossover frequency will give your sound
more “thump.”
