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 diaphragm high-frequency compression driver on a symmetrical constantdirectivity 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.

CHAPTER 1: INTRODUCTION
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 store DC power and
tolerate voltage drops, thereby accommodating light-gauge
cables and lengthy cable runs.
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 optional adjustable
bracket is also available for wall mounting the HMS-10 with
downtilt or uptilt.
HMS-10 loudspeakers require a Meyer Sound 48 V DC
external power supply, such as the MPS-488HP. The singlespace 19-inch rack unit receives eight channels of balanced
audio from its XLR female Channel Inputs and routes the
audio, along with 48 V of DC power, to its eight Channel
Outputs. The Channel Outputs, which are available as
Phoenix 5-pin male connectors, deliver DC power to up to
eight HMS-10 loudspeakers at cable lengths 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 or equivalent) 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
using heavier wire gauges.
HMS-10 with Fixed Mount Bracket
MPS-488HP External Power Supply
TIP: For complete information on using the
MPS-488HP external power supply, refer to the
MPS-488HP Operating Instructions.
NOTE: The MPS-488HP external power supply
replaces the MPS-488 model, which was originally designed for use with MM-4XP loudspeakers.
The MPS-488 is also compatible with HMS-10 loudspeakers and can drive up to four units (using every
other Channel Output).
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: HMS-10 LOUDSPEAKER
HMS-10 INPUT CONNECTOR
The HMS-10 receives DC power and balanced audio from
its Phoenix 5-pin male connector on the top panel. The connector’s five pins include two pins for DC power (negative
and positive) and three pins for balanced audio (shield, negative, and positive). These pins are clearly labeled on the
HMS-10 top panel. The connector accepts conductors up to
12 AWG (American Wire Gauge) or 2.5 mm2. To function
properly, the HMS-10 requires an external 48 V DC power
supply.
HMS-10 CURRENT DRAW AND CABLE
REQUIREMENTS
Each HMS-10 loudspeaker draws a maximum current of
3.31 A rms and 3.45 A peak from its external 48 V DC power
supply. The current draw for the HMS-10 is dynamic and
fluctuates as operating levels change. The cabling between
the HMS-10 and its external power supply adds resistance
and hence causes a voltage drop at the loudspeaker.
Because lower voltages compromise peak SPL, and in
some cases frequency response, cable resistance should be
minimized.
NOTE: For long cable runs, you can use a large
cable gauge for DC power and a separate balanced audio cable for audio.
Cable Lengths and Cable Gauges for HMS-10
Loudspeakers
HMS-10 Input Connector
A single composite cable (such as Belden 1502 or equivalent) can be used to route both DC power and balanced
audio to the HMS-10 loudspeaker.
Each HMS-10 loudspeaker comes with one Phoenix 5-pin
female cable connector for making loudspeaker cables. For
information on HMS-10 cable requirements, see “HMS-10
Current Draw and Cable Requirements” on page 9. For
information on cables and cable accessories available from
Meyer Sound, see Appendix A, “HMS-10 Accessories.” For
information on cable assembly, see Appendix B, “HMS-10
Cable Assembly.”
CAUTION: When wiring HMS-10 loudspeaker
cables, it is extremely important that each pin
be wired correctly. Make sure the 48 V DC from the
external power supply is wired directly (and only) to
the 48 V DC pins on the HMS-10 loudspeaker connector, and that the polarity is observed (negative to
negative, positive to positive) to avoid damage to the
loudspeaker. In addition, make sure that audio pins
are wired correctly; polarity reversals for audio signals
affect system performance.
!
Cable lengths of up to 150 feet between the HMS-10 and its
external power are supported with only 1 dB of peak SPL
loss when using 18 AWG wire. Longer cable lengths are
possible with heavier wire gauges (see Table 1 and Table 2).

CHAPTER 2: HMS-10 LOUDSPEAKER
Calculating the Maximum Cable Length
The maximum cable length for an HMS-10 can be calculated with the following formula:
maximum length = 2 ohms / 2 * cable resistance
For example, the maximum length of an 18 AWG cable with
a resistance of 0.00636 is 157.2 feet (2 / 2 * 0.00636).
WIRING HMS-10 LOUDSPEAKER CABLES
WITH BELDEN 1502 CABLE (OR EQUIVALENT)
When wiring HMS-10 loudspeaker cables with Belden 1502
cable, use the conventions in Table 3. The red and black
wires in the Belden 1502 cable have a thicker gauge than
the other three wires and should be used for DC power. The
blue, white, and shield wires are shielded together and
should be used for audio.

CHAPTER 3: POWERING HMS-10 LOUDSPEAKERS
CONNECTING HMS-10 LOUDSPEAKERS TO
THE MPS-488HP EXTERNAL POWER SUPPLY
HMS-10 loudspeakers require a Meyer Sound 48 V DC
external power supply, such as the MPS-488HP. The singlespace 19-inch rack unit receives eight channels of balanced
audio from its XLR female Channel Inputs and routes the
audio, along with 48 V of DC power, to its eight Channel
Outputs. The Channel Outputs, which are available as
Phoenix 5-pin male connectors, deliver DC power to up to
eight HMS-10 loudspeakers at cable lengths 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 or equivalent) 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
using heavier wire gauges.
MPS-488HP
TIP: For complete information on using the
MPS-488HP external power supply, refer to the
MPS-488HP Operating Instructions.
To connect HMS-10 loudspeakers to the MPS-488HP:
1. Power off the MPS-488HP.
2. Connect audio sources (from a mixer or processor) to the
MPS-488HP Channel Inputs. Use balanced XLR cables.
3. Use the MPS-488HP Link switches to route Channel
Inputs to the desired Channel Outputs. For information
on the MPS-488HP Link switches, refer to the
MPS-488HP Operating Instructions.
4. Connect the HMS-10 loudspeakers to the MPS-488HP
Channel Outputs. Use a composite cable (such as
Belden 1502 or equivalent) outfitted with Phoenix connectors and wired for both DC power and balanced
audio.
CAUTION: Make sure HMS-10 loudspeaker
cables are wired correctly. For details on
assembling loudspeaker cables, see Appendix B,
“HMS-10 Cable Assembly.”
!
MPS-488HP with Eight HMS-10 Loudspeakers
TIP: You can use two separate cables for
HMS-10 loudspeaker connections: a 2-conductor cable for DC power and a 3-conductor cable for
balanced audio, both attached to a single Phoenix
connector on each cable end. This allows you to use
a larger gauge for the DC cable so you can achieve
longer cable runs (see “Cable Lengths and Cable
Gauges for HMS-10 Loudspeakers” on page 9).
5. Power on the MPS-488HP and monitor the LEDs on the
front panel to verify connections. For information on the
MPS-488HP LEDs, refer to the MPS-488HP Operating
Instructions.
6. Enable output from the audio sources (from the mixer or
processor) connected to the MPS-488HP.
11
CHAPTER 3: POWERING HMS-10 LOUDSPEAKERS
CONNECTING HMS-10 LOUDSPEAKERS TO
THE MPS-488 EXTERNAL POWER SUPPLY
The original MPS-488 was designed for use with the
MM-4XP miniature loudspeaker. While the MPS-488 can
power up to eight MM-4XP loudspeakers, it can only power
up to four HMS-10 loudspeakers (due to the HMS-10’s
higher power requirements and current draw).
X X
X X
X X
X
X
MPS-488
MPS-488 with Four HMS-10 Loudspeakers
Because the MPS-488 can power a maximum of four
HMS-10 loudspeakers, the loudspeakers should only be
connected to Channel Outputs 1, 3, 5, and 7. Do not use the
even-numbered channel outputs.
NOTE: The MPS-488HP external power supply
replaces the MPS-488 model, which was originally designed for use with MM-4XP loudspeakers.
The MPS-488 is also compatible with HMS-10 loudspeakers and can drive up to four units (using every
other Channel Output).
12
CHAPTER 4: MOUNTING HMS-10 LOUDSPEAKERS
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. This chapter describes how
to mount the HMS-10 with these two mounting options.
IMPORTANT SAFETY CONSIDERATIONS
MOUNTING HMS-10 LOUDSPEAKERS WITH
THE FIXED MOUNT BRACKET

[142.24 mm]
When installing Meyer Sound loudspeakers, the following
precautions should always be observed:
■
All Meyer Sound products must be used in accordance
with local, state, federal, and industry regulations. It is
the owner’s and user’s responsibility to evaluate the reliability of any rigging or mounting method for their application. Rigging should only be carried out by
experienced professionals.
■
Use mounting and rigging hardware that has been rated
to meet or exceed the weight being hung.
■
Make sure to attach mounting hardware to the building's
structural components (studs or joists), and not just to
the wall surface. Verify that the building's structure and
the anchors used for the installation will safely support
the total weight of the mounted loudspeakers.
■
Use mounting hardware appropriate for the surface
where the loudspeaker will be installed.
■
Make sure bolts are tightened securely. Meyer Sound
recommends using Loctite® on bolt threads and safety
cables.
■
Inspect mounting and rigging hardware regularly. Immediately replace any worn or damaged components.

Mark two mounting holes on the wall using the wall
plate’s center mounting slots as a guide.
–
Drill two 5/16” pilot holes, 2.5 inches deep, at the
marked locations.
–
Install the wall anchors in the pilot holes so they are
flush with the wall surface.
–
Install the wood screws in the wall anchors. Leave the
screws extended approximately 3/8” from the wall
surface.
3. Reattach the wall plate to the loudspeaker plate with the
previously removed four washers and screws. The washers should be placed on the outside of the loudspeaker
plate.
4. Hang the mounting bracket, with the HMS-10 attached,
on the wall screws.

CHAPTER 4: MOUNTING HMS-10 LOUDSPEAKERS
5. Adjust the tilt of the HMS-10 from –13 degrees (downtilt)
to +5 degrees (uptilt). Tighten the four side screws to
secure the HMS-10.
NOTE: Make sure the four side screws are
completely tightened to ensure that the
HMS-10 won’t move from its desired position.

NOTE: When mounting the HMS-10 in a soffit,
allow at least 3 inches above the unit to provide the necessary ventilation for its amplifier and
heat sink.
MOUNTING HMS-10 LOUDSPEAKERS IN
SOFFITS
When mounting the HMS-10 in a soffit, use a soffit that measures at least 24" wide by 36" high by 15" deep (610 mm x
914 mm x 381 mm). This ensures that the loudspeaker's full
80-degree horizontal by 80-degree vertical horn coverage
will reach the listener. If the soffit is deeper than 15”, or the
HMS-10 is angled down, the overall height of the soffit
should be increased to accommodate the horn’s vertical
coverage.

In addition, make sure to allow at least 3 inches above the
HMS-10 for the mounting bracket to slide into place. The
extra space also provides the necessary ventilation for the
unit’s amplifier and heat sink.

TIP: If more than 5 degrees of uptilt are needed
for the HMS-10, the adjustable bracket can be
oriented upside down (mount the wall plate on the
wall upside down and remove and reattach the loudspeaker plate to the HMS-10 also upside down). This
orientation allows uptilt angles up to 13 degrees.

NOTE: The MPS-488HP external power supply replaces the MPS-488 model, which was originally designed
for use with MM-4XP loudspeakers. The MPS-488 is also compatible with HMS-10 loudspeakers and can
drive up to four units (using every other Channel Output).
NOTE: Bulk cables use Belden 1502R (regular) or Belden 1502P (plenum) cable. Belden 1502 is a composite
cable comprised of two 18 AWG wires for DC power, two 22 AWG wires for balanced audio, and one 24 AWG
wire for audio shield. This single cable can deliver both DC power and balanced audio to loudspeakers at cable runs
of up to 150 feet with only 1 dB of loss in peak SPL. Longer cable runs are possible with heavier gauges for DC
power and separate cables for balanced audio. For more information, see “HMS-10 Current Draw and Cable
Requirements” on page 9.

APPENDIX B: HMS-10 CABLE ASSEMBLY
CAUTION: When wiring HMS-10 loudspeaker cables, it is extremely important that each pin be wired correctly.
Make sure the 48 V DC from the external power supply is wired directly (and only) to the 48 V DC pins on the
HMS-10 loudspeaker connector, and that the polarity is observed (negative to negative, positive to positive) to avoid
damage to the loudspeaker. In addition, make sure that audio pins are wired correctly; polarity reversals for audio signals affect system performance.

ASSEMBLING PHOENIX-TO-PHOENIX LOUDSPEAKER CABLES
To connect the HMS-10 loudspeaker directly to the MPS-488HPp power supply, you need a Phoenix 5-pin female to
Phoenix 5-pin female cable. The following procedure documents how to assemble this cable.
Assembled Phoenix-to-Phoenix Cable
To assemble a Phoenix-to-Phoenix cable:
1. If the cable has not yet been stripped, strip one end of the cable. Strip the outer shielding 1 inch and then strip the black,
red, blue, and white wires .275 inch.
