Immersive surround applications

The HMS-10 cinema surround loudspeaker, with IntelligentDC technology, is optimized for use in cinemas, theatres, screening rooms, and other surround applications. The self-powered, full- range HMS-10 maintains a wide dynamic range, exceptional fidelity, and clarity during the most demanding of digital soundtracks. As part of Meyer Sound's Cine-Studio series, the HMS-10 integrates seamlessly with Acheron® screen channel loudspeakers, as well as with other HMS surround loudspeakers. 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 delivers the full intensity and nuance of cinema surround channels to every listener without compromise.

The HMS-10's transducers include one 10-inch low-frequency, long-excursion cone driver and one 2-inch diaphragm high-frequency compression driver on a symmetrical, constant- directivity 80-degree horn that delivers exceptional consistency. 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 circuitry, and correction filters for flat phase and frequency responses.

The versatile HMS-10 can be mounted on walls or ceilings at fixed or adjustable angles with the optional wall-mount brackets (fixed or adjustable), hinge bracket, U-bracket, or half- yoke, allowing units to be deployed per the requirements of any surround application or immersive cinema format.

With IntelligentDC technology, the HMS-10 receives DC power and balanced audio from a single Phoenix™ 5-pin male connector. Powering the unit from an external source eliminates the need for AC conduits while still preserving the advantages of self-powered 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 requires an external MPS-488HP IntelligentDC power supply. The single-space 19- inch rack unit distributes DC power and balanced audio to up to eight HMS-10 loudspeakers, or other Meyer Sound IntelligentDC 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. Meyer Sound's RMS remote monitoring system is optionally available for the MPS-488HP.

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 setups. The HMS-10's textured finish and black cloth grille blend smartly with any theatre decor.
