CHAPTER 1: INTRODUCTION
ers, or up to four HMS-15 loudspeakers. Composite multi-
conductor cables, such as Belden
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.
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 sup-
pression. The HMS-15AC is optionally available with its own
onboard RMS remote monitoring system module for compre-
hensive monitoring of loudspeaker parameters from a Mac or
Windows-based computer.
The versatile HMS can be suspended or mounted on walls or
ceilings at fixed or adjustable angles with optional half-yoke,
U-bracket, or wall-mount brackets, allowing it to be deployed
per the requirements of any surround application or immer-
sive 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 instal-
lations. The HMS cabinet features a black textured finish and
an acoustically transparent, detachable, black cloth grille that
blend smartly with any theatre decor.
