Meyer Sound HMS-10 Operating Instructions Manual page 8

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 advan-
tages 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.
HMS-10 loudspeakers require a Meyer Sound 48 V DC
external power supply, such as the MPS-488HP. The single-
space 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 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 origi-
nally designed for use with MM-4XP loudspeakers.
The MPS-488 is also compatible with HMS-10 loud-
speakers 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 design-
ing a new room from scratch or adding surround channels to
an existing setup.

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.
