CINE-STUDIO
HMS Cinema Surround Loudspeaker
The HMS cinema surround loudspeaker is optimized
for use in cinemas, high-end private theatres,
screening rooms, and other surround applications.
Designed to complement Meyer Sound’s Acheron™
HMS-10 Cinema Surround
Loudspeaker with Grille Frame
screen channel loudspeakers, the self-powered
HMS maintains a wide dynamic range, exceptional
fidelity, and precise clarity during the most
demanding of digital soundtracks. Boasting a wide
frequency range and a generous linear peak SPL
with very low distortion, the HMS delivers the full
intensity and nuance of cinema surround channels
to every listener without compromise.
The HMS cinema surround loudspeaker is available
in five models: HMS‑5, HMS‑10, HMS‑12, HMS‑15,
and HMS‑15AC, ranging in size, weight, driver size,
and power to accommodate a wide range of venues
and applications. The proprietary long-excursion
cone drivers and diaphragm compression drivers
are driven by an onboard amplifier that includes
an active crossover, driver protection circuitry,
and correction filters for flat phase and frequency
response. A constant-directivity horn provides
uniform, full-range, consistent coverage.
The HMS‑5, HMS‑10, HMS‑12, and HMS‑15 are
equipped with IntelligentDC technology and
receive DC power and balanced audio from
composite Phoenix™ 5-pin connectors. Powering
the loudspeakers from an external DC source
eliminates the need for AC conduits while
preserving the advantages of self-powered
systems. IntelligentDC loudspeakers require
an MPS‑488HP external power supply. The
single-space 19-inch rack unit distributes
DC power and balanced audio to up to eight
HMS‑5, HMS‑10, or HMS‑12 loudspeakers,
or up to four HMS‑15 loudspeakers.
Composite multiconductor cables, such as
Belden® 1502 or equivalent, can deliver
both DC power and balanced audio to
loudspeakers at cable lengths up to 150 feet
with just 1 dB of loss in peak SPL using
18 AWG wire. Longer cable runs are possible
with heavier gauges. The MPS‑488HP is
optionally available with an RMS™ remote
monitoring system module for monitoring
voltage and current draw for its attached
loudspeakers from a Mac® or Windows®based computer.
HMS-5 Compact Cinema
Surround Loudspeaker
The HMS‑15AC is an AC-powered version
of the HMS‑15. Its Intelligent AC™ power
supply provides automatic voltage
selection, EMI filtering, soft current
turn-on, and surge suppression. The HMS‑15AC
is optionally available with its own onboard
RMS™ remote monitoring system module for
comprehensive monitoring of loudspeaker
parameters from a Mac or Windows-based
computer.
HMS-12 High-Power Cinema
Surround Loudspeaker
The versatile HMS can be suspended or mounted
on walls or ceilings at fixed or adjustable angles
with optional half-yoke, U-bracket, or wallmount brackets, allowing it to be deployed per
the requirements of any surround application or
immersive cinema format.
Meyer Sound’s industry-leading self-powered
technology not only delivers unparalleled and
consistent audio fidelity but also simplifies
installation, whether designing new rooms from
scratch or adding surround channels to existing
installations. The HMS cabinet features a black
textured finish and an acoustically transparent,
detachable, black cloth grille that blend smartly
with any theatre decor.

The UP‑4XP ultracompact loudspeaker,
with IntelligentDC technology, is ideally
suited for applications requiring a small,
inconspicuous cabinet that also delivers
high sound pressure levels, low distortion,
and uniform directional control. The selfpowered UP‑4XP offers exceptional audio
performance in a compact package with the
advantages of a remote power supply. As
a standalone loudspeaker, the UP‑4XP can
be used for vocal reinforcement, frontfill
coverage, and delay coverage for underbalcony applications. The UP‑4XP can also
be paired with an optional subwoofer to
create a full-range system.
The UP‑4XP boasts a wide operating
frequency range of 66 Hz to 18 kHz and a
maximum peak SPL of 121 dB, with very low
distortion. The unit’s high-frequency section
includes a 1-inch metal dome tweeter on a
constant-directivity, high-frequency horn
with a 100-degree beamwidth. The low/
mid-frequency section includes two 4-inch
cone transducers that work in parallel at
low frequencies — delivering a combined

acoustic output — with one of the drivers
rolling off at higher frequencies to prevent
interference (due to comb filtering effects)
in the crossover region. The proprietary
UP‑4XP drivers, which are manufactured
at Meyer Sound’s factory in Berkeley,
California, are powered by three channels
of onboard power amplification that include
an active crossover, driver protection, and
frequency and phase correction circuitry.
With IntelligentDC technology, the UP‑4XP
receives DC power and balanced audio from
a single loudspeaker connector, available as
Phoenix™ 5-pin male or sealed SwitchCraft®
EN3™ 5-pin male. Powering the unit from
an external source eliminates the need for
wiring conduits while still preserving the
advantages of self-powered systems. The
UP‑4XP’s amplifier and signal-processing
circuits store DC power and tolerate voltage
drops, thereby accommodating light-gauge
cables and lengthy cable runs.
The UP‑4XP requires an external MPS‑488HP
IntelligentDC power supply. The single-
Features & Benefits
space 19-inch rack unit distributes DC
power and balanced audio to up to eight
UP‑4XP loudspeakers, or other Meyer Sound
IntelligentDC loudspeakers. Composite
multiconductor cables, such as Belden® 1502
or equivalent, can deliver both DC power and
balanced to loudspeakers at cable lengths up
to 150 feet with just 1 dB of loss in peak SPL
using 18 AWG wire. Longer cable lengths are
possible with heavier wire gauges. Meyer
Sound’s RMS remote monitoring system is
optionally available for the MPS‑488HP.
The UP‑4XP’s durable cabinet is coated with
a black textured finish and includes top and
bottom mounting plates with 3/8”-16 or
metric M10 threaded nuts. QuickFly mounting
options include the MUB‑UP4 U-bracket,
MYA‑UP4 cradle-style yoke, and 1-3/8”
(35 mm) diameter pole-mount adaptor.
Other options include weather protection

–2.0 dBV (0.8 V rms) continuous average is typically the onset of
limiting for noise and music
Audio source must be capable of producing +16 dBV (6.3 V rms,
9.0 V peak) into 600 Ω to produce the maximum peak SPL over the
operating bandwidth of the loudspeaker
1. Recommended maximum operating
frequency range. Response depends
on loading conditions and room
acoustics.
2. Measured free-field with pink noise
at 1 meter, 1/3-octave frequency
resolution.
3. Measured free-field with music,
referred to 1 meter.
4. Taken from peak SPL, referred to
A-wtd noise floor.
5. At this frequency, the metal dome
tweeter and top low-frequency
driver (closest to the tweeter)
produce equal sound pressure levels.
6. Below 400 Hz, both low frequency
drivers are active. At 400 Hz, the
bottom low-frequency driver is
attenuated by –3 dB and rolled off
at higher frequencies. This reduces
interaction in the higher frequencies
(shorter wavelengths) of the tweeter
and maintains optimum polar and
off-axis frequency responses.

will produce into the nominal load
impedance.

Architect Specifications
The loudspeaker shall be a self-powered, fullrange system; the transducers shall consist of
two 4-inch low-frequency cone drivers and one
1-inch high-frequency metal dome tweeter. The
loudspeaker system shall incorporate internal
processing electronics and a three-channel
amplifier, one channel for each driver. Processing
functions shall include equalization, phase
correction, signal division, and driver protection.
The crossover point shall be 1.5 kHz. Amplifier
channels shall be class D. Amplifier output power
shall be 500 watts total for all three channels.
Distortion (THD, IM, TIM) shall not exceed 0.02%.
Performance specifications for a typical
production unit shall be as follows, measured at
1/3-octave resolution: operating frequency range
shall be 66 Hz to 18 kHz; phase response shall be
±45 degrees from 360 Hz to 12 kHz; maximum peak
SPL shall be 121 dB at 1 meter, free field. Coverage
shall be 100-degree horizontal by 100-degree
vertical.
The loudspeaker shall be equipped with either a
Phoenix 5-pin male or EN3 5-pin male connector
(three pins for balanced audio and two pins for
DC power). The audio input shall be electronically
balanced with a 10-kOhm impedance and accept
a nominal –2.0 dBV (0.80 V rms, 1.12 V peak)
input signal. DC blocking and RF filtering shall be
