Architectural Specifications
The loudspeaker shall be a compact, self‑powered, linear, low‑distortion, line array loudspeaker. Its transducers shall include two 9‑inch long‑excursion cone drivers and one 3‑inch diaphragm compression driver coupled to a constant‑directivity horn through a patented REM manifold.
The loudspeaker shall incorporate internal processing and a 3‑channel, open‑loop, class D amplifier. Processing shall include equalization, phase correction, driver protection, and signal division. Performance specifications for a typical production unit shall be as follows, measured at 1/3‑octave resolution: operating frequency range shall be 55 Hz–18 kHz; phase response shall be 92 Hz–18 kHz ±30 degrees. Maximum SPL for the LEOPARD and LEOPARD‑M80 shall be 142 dB, measured in free‑field at 4 m referred to 1 m using noise. Linear peak SPL for the LEOPARD shall be 133.5 dB with 18 dB crest factor; linear peak SPL for the LEOPARD‑M80 shall be 135 dB with 19 dB crest factor; both are measured free‑field with M‑noise at 4 m referred to 1 m.
Audio connectors shall be XLR 3‑pin, female and male, accommodating balanced audio, or XLR 5‑pin, accommodating both balanced audio and RMS.
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 range shall be 100–240 V AC at 50–60 Hz. AC power connectors for input and loop output shall be powerCON 20. Maximum long‑term continuous current draw shall be 3.0 A rms at 115 V AC, 1.5 A rms at 230 V AC and 3.4 A rms at 100 V AC. 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 with a slightly textured black finish. The enclosure shall include end frames with captive GuideALinks for linking units in vertical arrays at splay angles from 0.5° to 15°. The front protective grille shall be powder‑coated, hex‑stamped steel with acoustical black mesh. Dimensions shall be W: 26.93 in (684 mm) x H: 11.11 in (282 mm) x D: 21.66 in (550 mm). Weight shall be 75 lb (34.0 kg).
The 110° coverage compact linear line array loudspeaker shall be the Meyer Sound LEOPARD. The narrow (80° coverage) compact linear line array loudspeaker shall be the Meyer Sound LEOPARD‑M80.
