Precautions

If an Electro-Voice loudspeaker is used outdoors on a sunny day, place the
loudspeaker in a shaded or covered area. The loudspeaker amplifiers have
protection circuits that temporarily shut the loudspeaker off when extremely
high temperatures are reached. This can happen on hot days when the
loudspeaker is in direct sunlight.

Do not use Electro-Voice loudspeakers in an environment where temperatures
are below 0°C (32°F) or exceed +40°C (104°F).

Never expose an Electro-Voice loudspeaker to rain, water, or high moisture.

Electro-Voice 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.

1.4

Suspension

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 suspending objects

overhead. Electro-Voice strongly recommends all loudspeakers be suspended taking into

account all current national, federal, state, and local laws and regulations. It is the

responsibility of the installer to ensure all loudspeakers are safely installed in accordance

with all such requirements. When loudspeakers are suspended, Electro-Voice strongly

recommends the system be inspected at least once per year or as laws and regulations

require. If any sign of weakness or damage is detected, remedial action should be taken

immediately. The user is responsible for making sure the wall, ceiling, or structure is capable

of supporting all objects suspended overhead. Any hardware used to suspend a loudspeaker

not associated with Electro-Voice is the responsibility of others.

The EKX series is the newest member of the Electro-Voice portable loudspeaker family, and
combines legendary EV sound quality and reliability with the latest technology — all in a
compact package suitable for a wide range of sound reinforcement scenarios, including
musicians/DJs and live/club/installed sound applications. The EKX series features eight (8)
models (four (4) powered and four (4) passive), including 12-inch and 15-inch two-way
models and 15-inch and 18-inch subwoofers.

EV-engineered components, Signal Synchronized Transducers (SST) waveguide design, and
Class D amplifiers (up to 1500 W) coupled with QuickSmartDSP all work together to provide
precise coverage and superior sound quality at high SPLs. EV’s award-winning industrial
design — with robust wood enclosures and durable EVCoat finish — ensures that EKX speakers
look as great as they sound.

Powered EKX models feature high-efficiency Class-D power amplifiers (up to 1500 W) with
integrated QuickSmartDSP, and deliver up to 134 dB SPL utilizing high-sensitivity transducers
designed and engineered by EV (12-inch EVS-12M woofer / 15-inch EVS-15M woofer, each
coupled with a DH-1M 1-inch titanium compression driver; 15-inch EVS-15C subwoofer / 18­inch EVS-18C subwoofer).

The EKX amplifier incorporates intelligent thermal management (with a variable-speed fan
controlled by multiple onboard sensors) which ensures superior performance and reliability in
demanding environmental conditions.

Powered models allow easy setup via four (4) presets (Music, Live, Speech*, Club), sub/top
system-match crossovers, three-band EQ*, five (5) user-programmable presets (Store and
Recall settings), visual monitoring of limiter status, input level control* and meters, and
master volume control to ensure optimal gain structure. (* not available on subwoofers)

Adapted from our touring systems, EV’s exclusive Cardioid Control Technology allows output
to be steered towards the audience with up to 35 dB reduction on stage when multiple subs
are deployed.

Suspension

The EKX-12P and EKX-15P enclosures have eight (8) M10 threaded points; six (6) points on
top of the enclosure and two (2) points on the bottom. Forged shoulder eyebolts rated for
overhead suspension may be used to suspend an individual loudspeaker, such as the EBK-M10
accessory.

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 suspending objects

overhead. Electro-Voice strongly recommends all loudspeakers be suspended taking into

account all current national, federal, state, and local laws and regulations. It is the

responsibility of the installer to ensure all loudspeakers are safely installed in accordance

with all such requirements. When loudspeakers are suspended, Electro-Voice strongly

recommends the system be inspected at least once per year or as laws and regulations

require. If any sign of weakness or damage is detected, remedial action should be taken

immediately. The user is responsible for making sure the wall, ceiling, or structure is capable

of supporting all objects suspended overhead. Any hardware used to suspend a loudspeaker

not associated with Electro-Voice is the responsibility of others.

Figure 5.1: Suspension points

Prior to use, inspect the suspension points and associated hardware for any cracks,
deformations, broken welds, corrosion, missing or damaged components which could reduce

Cardioid Control Technology

The EKX-15SP and EKX-18SP subwoofers have cardioid array processing originally developed
for Electro-Voice concert subwoofer systems. Cardioid subwoofer arrays can be used to direct
the output of an array of subwoofers in order to limit excessive amounts of bass in undesired
areas. These arrays can be used to keep bass off of a stage, provide more consistent bass
coverage in the audience, and reduces bass in the surrounding area.
Multiple EKX-15SP or EKX-18SP can be arrayed to create a cardioid polar pattern. See
Cardioid pattern top view. The cardioid setting in the DSP menu is optimized to produce a
rear rejection of up to 35 dB without any additional processing. The rejection may be less in
smaller indoor environments than in larger outdoor environments. For best performance,
adhere to the following guidelines:
The subwoofers must all be the same model, for example all - EKX-15SP or all - EKX-18SP.
▪ The subwoofers must be physically placed in one (1) of the options shown. See Cardioid

physical alignment.

▪ Front firing subwoofers use the NORMAL location setting, and rear firing subwoofers use

the CARDIOID setting. All other settings should be the same between front and rear firing
subwoofers. For more information, see Subwoofer DSP control menu, page 28.

electronics are on, the signal routing is correct, the
source is active; the volume is turned up, etc.
Correct/repair/replace as necessary. If there is sound,
the problem is wiring.

Wiring Verify you have connected the correct cables to the

amplifier. Play something at a low level through the
amplifier. Connect the test loudspeaker in parallel with
the malfunctioning line. If the sound level is gone or is
very weak, the line has a short in it (possibly a severe
scrape, pinch, or a missed connection). Using the test
loudspeaker, move down the line and test each
connection/junction until you find the problem and
correct it. Observe proper polarity.

Verify level controls of the source are properly structured
by using the VU meter indicator on the LCD screen. If the

input or source level is too high. Fore more information,
see System status, page 21.

Reduce the microphone levels at the mixing console or
input source. If the microphone is connected directly to
the speaker, reduce the input level on the speaker.
Positioning the microphone close to the sound source
increases gain-before-feedback. See problem 6.

Change the MODE to LIVE or SPEECH. For more
information, see Full-Range loudspeaker DSP control
menu, page 23.

Whenever possible setup the loudspeakers so the
microphone is behind them. If using the loudspeaker in a
monitor position, aim the loudspeaker to the back of the
microphone.

Press and hold the MASTER VOL knob for 5 seconds. For
more information, see DSP controls, page 22.
