DESCRIPTION • • • •

Mid/High VA4 loudspeaker system Optimized for permanent installation only Horn-loaded 10-in cones with VA4 phase plug 2-in exit/75mm voice coil compression driver on constant directivity horn

The new MQ Series represents the next generation of permanent installation loudspeaker systems. Using VA4 Technology developed for the new KF700 Series, the MQ range replaces the MH and BV ranges of Virtual Array systems. The Series comprises matched sets of mid/high and low frequency enclosures that enjoy complementary dimensions and trapeziod angles to facilitate the creation of optimizedcoverage arrays. The MQ1394 uses a horn-loaded 10-in midrange cone with a specially designed geometry that produces a time-coherent wavefront through the upper portion of the midrange that is critical to vocal articulation. A phase plug with radial slots then serves to reduce the mechanical reactance of the subsystem without affecting the directivity of the source, allowing for flawless arraying of multiple MQ mid/high modules. A high power 2-in exit/75mm voice coil high frequency compression driver is mounted on a constant directivity horn for consistent, accurate dispersal of HF information. The MQ1394 provides a nominal coverage pattern of 90° (h) x 40° (v).

DESCRIPTIVE DATA

APPLICATION

Configuration Powering MF Subsystem

The MQ1394 mid/high module works with the MQ1312 triple 12-in low frequency module to create arrays for use in a wide variety of permanently installed applications. The most common array configuration is 2x MQ1394’s separated by a single MQ1312. Unlike most other 90° horizontal coverage array modules, the MQ1394 is designed to tight pack with the MQ1312 to achieve optimal coverage. This provides an excellent center channel array for large, fanshaped venues that use an L/C/R configuration. All MQ Series enclosures feature a comprehensive system of 3/8”-16 threaded mounting points for maximum flexibility when suspending arrays overhead.

The MF driver shall be loaded into a midrange horn constructed of 3mm birch plywood reinforced with high density polyurethane foam. The MF horn shall incorporate a phase/ displacement plug. The HF driver shall be loaded on constant directivity horn with a nominal coverage pattern of 90° (h) x 40° (v). An internal passive filter network shall provide system equalization. System frequency response shall vary no more than ±3 dB from 190 Hz to 19 kHz measured on axis. The midrange frequency section shall produce a Sound Pressure Level (SPL) of 108.5 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 140.5 dB SPL on axis at 1 meter. The high frequency section shall produce a Sound Pressure Level (SPL) of 110.5 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 139.5 dB SPL on axis at 1 meter. The midrange frequency section shall handle 400 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 8 Ohms. The high frequency section shall handle 200 Watts of amplifier power (AES Standard) and shall have a nominal impedance of 8 Ohms. The loudspeaker enclosure shall be trapezoidal in shape. It shall be constructed of 15mm thickness void-free cross-grainlaminated Baltic birch plywood and shall employ extensive internal bracing. It shall be finished in black catalyzed polyurethane. Input connectors shall be 4-terminal barrier strip and one Neutrik NL4 Speakon. A total of sixteen 3/8"-16 threaded mounting/suspension points (4 each top, bottom and sides) shall be provided. The front of the loudspeaker shall be covered with a powder coated perforated steel grill. The two-way mid/high loudspeaker shall be the EAW model MQ1394.
