Meyer Sound’s ULTRA-X40 and ULTRA-X42 designs continue the tradition
of the highly successful UPA loudspeakers—so versatile they have been
a universal standard in almost every application for over 35 years. From
touring performances to theme parks, worship venues to theater shows,
and lecture halls to large scale concerts, Meyer Sound technology has
delivered exceptional fidelity with high power, low distortion, and uniformly
predictable behavior.

To this legacy, Meyer Sound incorporated technology from the popular
and award-winning LEO® Family of loudspeakers to bring multiple
enhancements to bear in the ULTRA-X40/42 designs:

• Innovative, highly efficient class D amplifier and advanced signal

processing that reproduce any sound source with linearity over a wide
dynamic range.

• Weight reduction of 25 lb (11 kg), as well as a reduction in overall size

compared to the UPA loudspeakers for increased power to weight
and size ratios.

• Concentric driver configuration with all the benefits of a coaxial driver,

yet none of the disadvantages. In addition, this configuration supports
directional control of frequencies down to 400 Hz.

• Extremely well-behaved, rotatable horns designed for very precise,

even coverage. These horn designs, in conjunction with the
concentric driver configuration, deliver consistent patterns despite the
orientation.

With these enhancements, the ULTRA-X40/42 loudspeakers provide high
power output, low distortion, and consistent polar response in a more
compact, vented enclosure. The ULTRA-X40 loudspeaker features two
8-inch cone low-frequency drivers and one 3-inch diaphragm compression
driver coupled with a rotatable 110° x 50° Constant-Q horn. A more
controlled pattern is available on the ULTRA-X42 model, which is fitted
with a 70° x 50° constant-Q horn.

Because of its proprietary, high-frequency horns, the beamwidth remains
consistent within close tolerances in both the horizontal and vertical planes
and across the horns’ operating frequency range. Uniformly predictable
polar behavior takes much of the guesswork out of system design and
assures optimal system performance.

A proprietary three-channel, class D digital power amplifier powers
the ULTRA-X40/42 loudspeakers, which each have a total peak power
output of 1950 watts. Advanced audio processing includes electronic
crossover, correction filters for phase and frequency response, and driver
protection circuitry. Phase-corrected electronics ensure flat acoustical
amplitude and phase response, resulting in exceptional impulse response
and precise imaging. The amplifier/processing package incorporates
Meyer Sound’s IntelligentAC™, which auto-selects the correct operating
voltage, suppresses high voltage transients, filters EMI and provides
soft-start power-up. The ULTRA-X40/42 cabinet provides audio XLR and
powerCON20 input and looping output connectors.

The optional RMS™ remote monitoring system module provides
comprehensive monitoring of loudspeaker parameters from a host
computer running Compass® software.

Meyer Sound builds the trapezoidal enclosure out of premium multi-ply birch
with a slightly textured black finish. A powder-coated, round-perforated
steel grille provides protection to the front of the loudspeaker.

The ULTRA-X40/42 includes 11 integral M8 rigging points. It also includes
an integral 35 mm stand mount receptacle with M20 threads for added
stability. With this versatile integrated rigging, the ULTRA-X40/42 is ready
for a wide variety of applications including those requiring pole mounting,
hanging individually in horizontal or vertical orientations, or clustering.

Optional rigging accessories include an adjustable 35 mm pole with M20
slug, a U-bracket, a yoke, a pinnable link on a channel that allows the
hanging of multiple units from a single pick-up point, and cluster plates
for horizontal and vertical loudspeaker grouping. Other options include
weather protection and custom color finishes.

NOTES

1. Loudspeaker system predictions for coverage and SPL are available in Meyer Sound’s MAPP System Design Tool.

2. Recommended maximum operating frequency range. Response depends on loading conditions and room acoustics.

3. Free-field, measured with 1/3 octave frequency resolution at 4 m.

4. Linear Peak SPL is measured in free-field at 4 m referred to 1 m. Loudspeaker SPL compression measured with M-noise at the onset of limiting,
2-hour duration, and 50-degree C ambient temperature is < 2 dB.

M-noise is a full bandwidth (10 Hz–22.5 kHz) test signal developed by Meyer Sound to better measure the loudspeaker’s music performance. It
has a constant instantaneous peak level in octave bands, a crest factor that increases with frequency, and a full bandwidth Peak to RMS ratio of
18 dB.

Pink noise is a full bandwidth test signal with Peak to RMS ratio of 12.5 dB.

B-noise is a Meyer Sound test signal used to ensure measurements reflect system behavior when reproducing the most common input spectrum,

and to verify there is still headroom over pink noise.

5. Pins 4 and 5 (RMS) only included with XLR 5-pin connector that accommodates both balanced audio and RMS signals.

6. Peak power based on the maximum unclipped peak voltage the amplifier will produce into the nominal load impedance.

7. AC power cabling must be of sufficient gauge so that under burst current rms conditions, cable transmission losses do not cause the
loudspeaker’s voltage to drop below the specified operating range.
