LYON Compact Linear Line Array Loudspeaker

ARCHITECTURAL SPECIFICATIONS

The loudspeaker shall be a self-powered, linear, low-distortion, line array loudspeaker. Its transducers shall include two 3 in diaphragm compression drivers coupled to a constant-directivity horn through a patented REM manifold, and two 12 in long-excursion cone drivers. The loudspeaker shall incorporate internal processing and a 3-channel class AB/H bridged amplifier with complementary MOSFET output stages. Protection circuits shall include TruPower limiting. The audio input shall be electronically balanced with a 10 kΩ impedance and accept a nominal 0  dBV (1.0  V rms) signal (+20  dBV to produce maximum SPL). Audio connectors shall be XLR 3-pin, female and male, accommodating balanced audio, or XLR 5-pin, accommodating both balanced audio and RMS. 

Performance specifications for a typical production unit shall be as follows, measured at 1/3-octave resolution: operating frequency range shall be 55  Hz–16.5  kHz; phase response shall be 80  Hz–16  kHz ±30  degrees; linear peak SPL shall be 143.5 dB, measured free-field with M-noise at 4 m referred to 1 m. The internal power supply shall perform EMI filtering, soft current turn on, and surge suppression. Power requirements shall be nominal 100, 110, or 230 V AC line current at 50–60 Hz. UL and CE operating voltage ranges shall be 95–125 V AC and 208–235 V AC at 50–60 Hz. Current draw during burst (< 1 sec) shall be 15.4 A rms at 115 V AC, 7.5 A rms at 230 V AC, and 8.2 A rms at 208 V AC. Current inrush during soft turn-on shall not exceed 15 A at 230 V AC. The AC power connector shall be a powerCON 32.

The loudspeaker shall include an RMS remote monitoring system module.

Components shall be mounted in an optimally tuned, vented enclosure constructed of premium multi-ply birch and coated with a slightly textured black finish. The front protective grille shall be powder-coated, hex-stamped steel with acoustical black mesh. Dimensions shall be 38.15 in (969 mm) wide x 14.85 in (377 mm) high x 21.00 in (533 mm) deep. Weight shall be 199 lbs (90.3 kg). The loudspeaker shall be the Meyer Sound LYON.
