MM-4XPD Directional Miniature Self-Powered Loudspeaker

MM-4XPD Directional Miniature Self-Powered Loudspeaker

The MM‑4XPD directional miniature self-powered loudspeaker with IntelligentDC technology was specifically designed for high quality distributed systems in reverberant spaces. The directional polar pattern of the MM-4XPD, especially at low frequencies, significantly reduces room excitation and increases intelligibility. Its flexible and easy-to-configure mounting options, as well as its ability to effortlessly reproduce both speech and music, make the MM‑4XPD an excellent choice for large distributed systems, theatrical presentations, museums, and small portable systems for corporate audio-visual, where intelligibility is critical.

FEATURES AND BENEFITS

Directional hypercardioid pattern provides 10dB of attenuation between the front and the back of the loudspeaker, even at low frequencies
Directional pattern reduces excitation of the room, desirable in highly reverberant spaces
Extremely compact size fits in small spaces
Patent pending technology that does not require additional tranducers to create directional effect, reducing energy, weight and volume
A convenient u-bracket allows for quick and easy mounting

APPLICATIONS

Restaurants, bars and highly reverberant public spaces
Large distributed systems
Trade show presentations

Specification

The loudspeaker shall be self-powered and include a single 4 in (103 mm) diameter cone transducer with a 4Ω, long-excursion voice coil. The loudspeaker shall incorporate a class-D power amplifier with a burst capability of 440 W peak into a nominal load of 4 Ω. Distortion (THD, IM, TIM) shall not exceed 0.02 percent.
Performance specifications for a typical production unit shall be as follows, measured at 1/3-octave resolution: operating frequency range, 120 Hz to 18 kHz; phase response, 330 Hz to 20 kHz ±45°; linear peak SPL shall be 111.5 dB measured with M-noise, free field at 4 m referred to 1 m. Horizontal and vertical coverage shall be hypercardioid with a <10 dB front-to-back ratio up to 500 Hz, 120° at 500 Hz to 4 kHz, 80° at 4 kHz to 10 kHz ±10°.
The loudspeaker shall be equipped with a single SwitchCraft EN3 5-pin connector (two pins for DC power, three pins for balanced audio). The audio input shall be electronically balanced with a 10 kΩ impedance and accept a nominal –2.5 dBV (0.75 V rms) input signal. Power requirements for the loudspeaker shall be an external Meyer Sound IntelligentDC power supply. Current draw for the loudspeaker during burst (<1 sec) shall be 2.2 A rms at 48 V. Current inrush during turn-on shall not exceed 7.0 A peak at 48 V.
Loudspeaker components shall be housed in a sealed, extruded aluminum enclosure with a black anodized finish. Custom painted colors shall be optionally available. Dimensions with grille frame shall be W: 4.04 in (103 mm) x H: 4.04 in (103 mm) x D: 7.95 in (202 mm) D with connector: 10.20 in (259 mm). Weight shall be 5.2 lb (2.4 kg). 3/8 in‑16 inserts on each side of the enclosure shall accommodate Meyer Sound mounting and rigging options.
The loudspeaker shall be the Meyer Sound MM‑4XPD.
