Architectural Specifications
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 an 80° horizontal by 50° vertical horn. The loudspeaker system shall incorporate internal processing electronics and a two-channel amplifier, one channel for each driver. Processing functions shall include frequency and phase correction, signal division, and protection for the low- and high-frequency sections. The crossover point shall be 580 Hz.
Each amplifier channel shall be class AB/bridged with complementary MOSFET output stages. Total burst power shall be 700 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 frequency range shall be 37 Hz to 18 kHz; phase response shall be 700 Hz to 17 kHz ±30°; linear peak SPL shall be 131.5 dB with crest factor > 15 dB, measured with M-noise, free field at 4 meters and referred to 1 meter.
The audio input shall be electronically balanced with a 10 kΩ impedance and accept a nominal 10 dBV (3.2 V rms) signal. Connector shall be XLR 3-pin female with parallel looping male.
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 current 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 2.9 A at 115 V AC, 1.5 A at 230 V AC and 3.3 A at 100 V AC. Current inrush during soft turn-on shall not exceed 11 A at 115 V AC, 18 A at 230 V AC, and 13 A at 100 V AC. AC power connector shall be PowerCON.
The loudspeaker system shall provide facilities for installing Meyer Sound’s optional RMS remote monitoring system.
All loudspeaker components shall be mounted in an acoustically vented enclosure constructed of premium multi-ply birch with a slightly textured black finish. Dimensions shall be W: 25.38 in (645 mm) x H: 30.78 in (782 mm) x D: 16.00 in (406 mm). Weight shall be 113 lb (51.26 kg). An optional version of the loudspeaker shall include side rigging attachment points and the MYA-AST mounting yoke.
The loudspeaker shall be the Meyer Sound Acheron Studio.
