System features
ETX Powered Loudspeakers from Electro-Voice build upon the legacy and heritage of EV, to
deliver the most advanced powered loudspeaker products for portable and permanent
applications. The output, response and coverage pattern of EV transducers are all optimized
via the breakthrough design approach known as SST (Signal Synchronized Transducers),
combined with state-of-the-art on-board DSP which is accessed via an easy-to-use single-knob
interface. EV designed and manufactured transducers include SMX woofer technology using
composite cone materials, flux stabilizing rings, and thermal management. This transducer
yields lower distortion, smooth response and high SPL. The high-efficiency DH3-B
compression driver has a convex diaphragm driving a coherent phase device extending
frequency response to 20 kHz. The ETX Powered Loudspeaker family features three (3) two-
way loudspeakers (10-inch, 12-inch and 15-inch with a 1.5-inch titanium compression driver),
a single three-way loudspeaker, and subwoofers with 15-inch and 18-inch drivers. ETX
Powered Loudspeakers combine EV-engineered intelligent DSP, high-powered amplifiers and
high-efficiency transducers to deliver that legendary EV sound and performance.

than one (1) inch is preferable). Prior to each use, inspect the loudspeaker enclosures for any
cracks, deformations, missing or damaged components, which could reduce enclosure
strength. Replace any loudspeaker systems damaged or missing hardware.

peaks which can cause distortion. Short-term blinking is not critical because the
integrated limiter keeps distortion under control. Constant lighting of PEAK indicates the
sound is negatively affected. Reducing the output volume (MASTER VOL) is strongly
recommended to reduce gain.
2. TEMP limiter – The temp limiter protects the transducer from thermal failures by
reducing the gain. The TEMP LIMITER will flash if any gain reduction is being done.

Subwoofer cardioid array
Subwoofer cardioid array
The ETX-15SP and ETX-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, provides more consistent bass
coverage in the audience, and reduces bass in the surrounding area.
Multiple ETX-15SP or ETX-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 30 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 ETX-15SP or all ETX-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 32.
▪ To add delay to the cardioid array, add the same amount to both the front and rear facing
subwoofers. For more information, see Subwoofer DSP control menu, page 32.

Troubleshooting
Problem Possible Cause(s) Action
1. No Sound Amplifier Connect a known working test loudspeaker to the amplifier
outputs. If there is no sound, verify all the 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.
