MEYER SOUND MM-4XP Miniature loudspeaker

Meyer Sound designed the MM‑4XP self‑powered miniature loudspeaker (with IntelligentDC technology) for high‑quality distributed systems. Housed in a compact aluminum enclosure, the MM‑4XP is especially suitable for installations involving space limitations and visibility concerns, such as fill and spot coverage, and hidden locations like chancel steps in houses of worship. Its flexible and easy‑to‑configure mounting options, as well as its ability to effortlessly reproduce both speech and music, make it an excellent choice for fixed applications, theatrical presentations (stage lip frontfill), and small portable systems for corporate AV.

The MM‑4XP’s proprietary 4‑inch cone transducer with on‑board amplification and signal processing, manufactured at Meyer Sound’s Berkeley, California factory, delivers an impressive linear peak SPL of 111.5 dB with crest factor >16.5 dB4 and a wide operating frequency range of 120 Hz to 18 kHz with very low distortion. The MM‑4XP exhibits the same high intelligibility and flat frequency and phase responses for which all Meyer Sound loudspeakers are known. Peak and rms limiters regulate loudspeaker temperatures and excursion, ensuring the MM‑4XP performs exceedingly well even when driven into overload.

With IntelligentDC technology, the MM‑4XP receives power and balanced audio from a SwitchCraft® EN3™ 5‑pin male input connector on its rear panel. Meyer Sound designed the MM‑4XP’s amplifier and signal‑processing circuits to store DC power and tolerate voltage drops, thereby accommodating light‑gauge cables and long cable runs.

MM‑4XP loudspeakers require a Meyer Sound external power supply. The compatible MM‑10 ACX miniature self‑powered subwoofer includes onboard DC power and audio routing for driving a pair of MM‑4XP miniature loudspeakers. The MPS‑488HP IntelligentDC power supply is ideal for larger installations with multiple loudspeakers; the single‑space rack‑mount unit distributes DC power and balanced audio to up to eight MM‑4XP loudspeakers or other compatible Meyer Sound low‑voltage loudspeakers. Another option is the 1RU, 1/2‑width, rack‑mount MPS‑482HP IntelligentDC power supply that offers two channels of audio and DC power.

Meyer Sound’s RMS™ remote monitoring system, which provides comprehensive monitoring of system parameters from a Mac® or Windows®‑based computer, is available as an option for the MPS‑488HP.
