THE HMS-10 SURROUND LOUDSPEAKER
Meyer Sound's HMS-10 is a full-range, two-way loudspeaker optimized for surround channels in theatres and rerecording stages. Designed to complement the Acheron™
line of screen channel loudspeakers, the self-powered
HMS-10 maintains a wide dynamic range, full fidelity, and
complete clarity during the most demanding of digital
soundtracks. Boasting a wide frequency range of 55 Hz to
18 kHz and a maximum peak SPL of 126 dB at 1 meter with
very low distortion, the HMS-10 ensures that the full intensity and nuance of cinema surround channels reach each
listener without compromise.

HMS-10 Surround Loudspeaker (Shown without Grille)
The HMS-10's transducers include a 10-inch low-frequency
long excursion cone driver and a 2-inch high-frequency
compression driver on a symmetrical constant-directivity
80-degree horn that delivers exceptional coverage. The proprietary drivers — designed and manufactured at Meyer
Sound's headquarters in Berkeley, California — are powered
by two channels of onboard amplification that include an
active crossover, driver protection, and frequency and phase
response correction circuitry.
Balanced audio and DC power are received by the HMS-10
from a Phoenix™ 5-pin male connector on its top panel.
Powering the unit from an external source eliminates the
need for wiring conduits while still preserving the advantages of self-powered loudspeaker systems. The HMS-10's
amplifier and signal-processing circuits are designed to
store DC power and tolerate voltage drops, thereby accommodating light-gauge cables and lengthy cable runs.
7
CHAPTER 1: INTRODUCTION
HMS-10 loudspeaker systems require an MPS-488P external power supply. The single-space 19-inch rack unit
receives balanced audio from its XLR female inputs and
routes the audio, along with 48 V of DC power, to its channel
outputs. The outputs — equipped with Phoenix 5-pin male
connectors — can deliver DC power to up to four HMS-10
loudspeakers at cable lengths of up to 150 feet with just
1 dB of loss in peak SPL using 18 AWG wire. The use of
composite multiconductor cables (such as Belden
®
1502)
allows a single cable to carry both DC power and balanced
audio to the HMS-10. Longer cable runs are possible for
moderate applications that don't drive the loudspeakers to
maximum output, or for installations with heavier wire
gauges.
MPS-488P Power Supply
NOTE: The MPS-488
P was originally designed
for use with the MM-4XP miniature loud-
speaker. While the MPS-488
P can power up to eight
MM-4XPs, it can only power up to four HMS-10s
(because of the HMS-10’s additional current draw).
The HMS-10's compact size, textured finish, and black cloth
grille blend smartly with any theater decor. The HMS-10
comes standard with a fixed bracket; an adjustable bracket
is also available for wall mounting the HMS-10 with downtilt
or uptilt.
Meyer Sound's industry standard self-powered loudspeaker
technology not only delivers unparalleled and consistent
audio fidelity but also simplifies installation, whether designing a new room from scratch or adding surround channels to
an existing setup.

CHAPTER 2: THE MPS-488P POWER SUPPLY
XXXXXXX
X
The MPS-488P power supply delivers DC power and balanced audio to Meyer Sound loudspeakers that require a
48 V DC external power supply. The MPS-488
P is a multi-
channel, switched-mode, regulated power supply that occupies one space in a standard 19-inch rack. The MPS-488
P
was originally designed for use with the MM-4XP miniature
loudspeaker. While the MPS-488
P can power up to eight
MM-4XPs, it can only power up to four HMS-10s (because
of the HMS-10’s additional current draw).
THE MPS-488P FRONT PANEL
The MPS-488P front panel includes a power switch, LEDs
for monitoring each loudspeaker channel, and fuses for
each channel.
MPS-488P Power Supply Front Panel
AC Power
The MPS-488P is powered on and off with the AC Power
switch.
Voltage and Load Current LEDs (1–8)
The Voltage and Load Current LEDs are useful for verifying
whether each channel output has voltage and whether the
connected loudspeakers are receiving DC power and audio.
MPS-488P with Four HMS-10s
NOTE: The MPS-488 power supply is available
in two models: the MPS-488
P, which is
equipped with Phoenix 5-pin male output connectors
(recommended for use with the HMS-10), and the
MPS-488
E, which is equipped with EN3 5-pin female
output connectors.
MPS-488
P Channel LEDs and Fuses
Voltage LEDs (1–8)
The blue Voltage LEDs indicate whether voltage is present
for each channel output. These LEDs should be lit when the
MPS-488
P is powered on. If a channel is not lit, its fuse may
need to be replaced. If a group of two Voltage LEDs is not lit
(1–2, 3–4, 5–6 or 7–8), one of the four MPS-488
P internal
power supplies may have failed.
Load Current LEDs (1–8)
The green Load Current LEDs indicate whether a loudspeaker is connected to the channel and receiving power.
As a channel’s audio signal increases, its LED glows
brighter. If an LED is not lit, check that the channel’s Voltage
LED is lit (the fuse is working) and verify the cable connection to the loudspeaker.

!
NOTE: Since HMS-10s should only be con-
nected to channel outputs 1, 3, 5, and 7, only
the Load Current LEDs for channels with connected
loudspeaker will light up (unlike the Voltage LEDs,
which will all light up).
Fuse Slow Blow (1–8)
Each loudspeaker channel is protected with its own fuse. A
maximum of one HMS-10 can be connected to each of four
output channels (1, 3, 5, and 7); connecting more than that
could cause a channel’s fuse to trip.
NOTE: When replacing fuses, make sure to
use a 2-amp, 250-volt slow-blow fuse (T2A250V). These fuses are available from Meyer Sound
(PN 420.027).
THE MPS-488P REAR PANEL
The MPS-488P rear panel includes an AC connector, eight
channel inputs for receiving source audio, eight channel outputs for delivering DC power and balanced audio, and seven
Links switches for routing audio from inputs to outputs.
MPS-488P Power Supply Rear Panel
CAUTION: Because the MPS-488
a maximum of four HMS-10 loudspeakers, the
HMS-10s should only be connected to channel outputs 1, 3, 5, and 7. Do not use the even-numbered
channel outputs.
P can power
Channel Inputs
Up to eight channels of balanced audio are received from the
MPS-488
P’s eight channel inputs. The inputs are equipped
with XLR female connectors (pin 1, ground; pin 2, signal positive; pin 3, signal negative). Make sure to use standard balanced XLR cables with all three pins connected on both ends.
MPS-488P Channel Inputs
Channel inputs default to being routed to their corresponding channel outputs but can also be routed to adjacent outputs with the Link switches, though this affects their input
impedance (see “Input Impedance for Linked Channel
Inputs” on page 11).
Link Switches
Link switches determine how channel inputs are routed to
channel outputs. When a channel input’s Link switch is OFF
(set to the down position), the input is only routed to its corresponding channel output: for example, channel input 1
routed to channel output 1. When a Link switch is ON (set to
the up position), the input is routed to its corresponding
channel output and the next adjacent channel output: for
example, channel input 1 routed to channel outputs 1 and 2.
If multiple, adjacent Link switches are enabled, the input is
routed to each adjacent channel output: for example, channel input 1 routed to channel outputs 1, 2, and 3.
AC Input
The MPS-488P has a PowerCon twist-lock AC connector
(line, neutral/line, earth). The connector can accept different
power cord types for outlets used throughout the world.
Make sure to use the correct power cord for the AC power in
your area. The MPS-488
P operates at an AC voltage range
of 100–240 V at 50–60 Hz.
