EAW MQ1312 Speaker User manual

SPECIFICATIONS MQ1312

FEATURES

• Low frequency loudspeaker system

• Optimized for permanent installation only

• 3x direct radiating 12-in woofers

• Optimized to array with MQ1364, MQ1366 and

MQ1394

DESCRIPTION

The new MQ Series represents the next generation of permanent installation loudspeaker 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 optimized-coverage arrays. The

MQ1312 uses three direct radiating 12-in woofer cones in an optimally tuned, vented enclosure.

APPLICATION

The MQ1312 low frequency module works with the MQ1364,

MQ1366 and MQ1394 mid/high modules to create arrays for use in a wide variety of permanently installed applications.

The most common array configuration is 2x MQ1364’s or

MQ1366’s separated by a single MQ1312. In such an array, a certain amount of splay must be provided to achieve optimal coverage.

When arraying 2x MQ1394’s separated by a single MQ1312, the modules should be tight packed to achieve optimal coverage. This provides an excellent center channel array for large, fan-shaped 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.

Applications include:

Large Houses of Worship

Stadiums Theater

Arena

Performing Arts Center

A & E SPECIFICATIONS

The low frequency loudspeaker systems shall incorporate 3x

12-in LF transducers. The LF drivers shall be mounted in separate vented subenclosures tuned for optimum low frequency response.

System frequency response shall vary no more than ±3 dB from

50 Hz to 1600 Hz measured on axis. The loudspeaker shall produce a Sound Pressure Level (SPL) of 100 dB SPL on axis at 1 meter with a power input of 1 Watt, and shall be capable of producing a peak output of 137.8 SPL on axis at 1 meter. The loudspeaker shall handle 1500 Watts of amplifier power (AES

Standard) and shall have a nominal impedance of 3x 8 Ohms.

The loudspeaker enclosure shall be trapezoidal in shape. It shall be constructed of 1/2-in thickness void-free cross-grainlaminated Baltic birch plywood and shall employ extensive internal bracing. It shall be finished in black polyurethane.

Input connectors shall be a 6-terminal barrier strip and 2x

Neutrik NL4 Speakon with connections as follows (LF1 is topmost driver, LF3 is lowest):

Pins 1 +/–

Pins 2 +/–

NL4 (left)
