The JM-1P arrayable loudspeaker combines Meyer Sound's famed clarity of sound and robust, self-powered performance with our latest breakthroughs in horn design, rigging and loudspeaker control to produce an extremely easy-to-use, highly versatile arrayable loudspeaker system powerful enough to act as a main system, but flexible enough to serve in any number of supporting roles whether horizontal or vertical, flown or stacked.
Features & Benefits
The loudspeaker shall be a self-powered, full-range system; the transducers shall consist of a 15-inch diameter cone driver and a 4-inch diaphragm compression driver on a 20-degree horizontal by 60-degree vertical horn. The loudspeaker system shall incorporate internal processing electronics and a two-channel amplifier, one channel for each driver. Processing functions shall include equalization, phase correction, signal division, and protection for the high- and low-frequency sections. The crossover point shall be 520 Hz.
Each amplifier channel shall be class AB/H with complementary MOSFET output stages. Burst capability for the low-frequency channel shall be 1000 watts total with nominal 2-ohm resistive load and 275 watts for the high-frequency channel with nominal 8-ohm resistive load. Peak power shall be 2550 watts. Distortion (THD, IM, TIM) shall not exceed 0.02%.
Performance specifications for a typical production unit shall be as follows, measured at 1/3-octave resolution: operating Notes: frequency range shall be 53 Hz to 18 kHz; phase response shall be ±45° from 580 Hz to 16 kHz; Linear peak SPL shall be 138 dB at 1 meter, free field.
The audio input shall be electronically balanced with a 10 kOhm impedance and accept a nominal 0 dBV (1.0 V rms, 1.4 V peak) signal. Connector shall be XLR (A-3) type female with parallel looping male. RF filtering shall be provided, and CMRR shall be greater than 80 dB from 50 Hz to 500 Hz.
The internal power supply shall perform automatic voltage selection, EMI filtering, soft current turn-on, and surge suppression. Power requirements shall be nominal 100, 110, or 230 V AC line at 50 or 60 Hz. UL and CE operating voltage range shall be 100 to 240 V AC. Maximum peak current draw during burst shall be 8.0 A at 115 V AC, 4.1 A at 230 V AC, and 9.2 A at 100 V AC. Current inrush during soft turn-on shall not exceed 7.1 A at 115 V AC, 8.4 A at 230 V AC, and 7.1 A at 100 V AC. AC power connectors shall be either a PowerCon with loop output.
The loudspeaker system shall provide facilities for installing Meyer Sound’s optional RMS remote monitoring system.
All components shall be mounted in an acoustically vented trapezoidal enclosure constructed of multi-ply hardwood with a black textured, hard-shell finish. The enclosure shall include end plates with GuideALinks for linking units in horizontal and vertical arrays; threaded metric M10 points accommodate Meyer Sound proprietary rigging hardware. The front protective grille shall be powder-coated, hex-stamped steel with black mesh screen.
Dimensions shall be 16.79" wide x 36.08" high x 29.30" deep (427 mm x 916 mm x 744 mm). Weight shall be 147 lbs (66.68 kg).
The loudspeaker shall be the Meyer Sound JM-1P.
