Architectural Specifications
The loudspeaker shall be a self‑powered, full‑range system. Its transducers shall include two 5‑inch cone drivers and one 1‑inch metal dome tweeter.
The loudspeaker system shall incorporate internal processing and a three‑channel amplifier, one channel for each driver. Processing functions shall include equalization, phase correction, signal division, and driver protection. Amplifier burst output power shall be 650 W total. Distortion (THD, IM, TIM) shall not exceed 0.02%.
Performance specifications for a typical production unit shall be as follows: operating frequency range, 75 Hz–20 kHz; phase response, 300 Hz–18 kHz ±60°; linear peak SPL is 118.5 dB with crest factor >14 dB, measured with M‑noise, free‑field at 4 m referred to 1 m; coverage shall be 100° horizontal by 100° vertical.
The loudspeaker shall receive DC power and balanced audio from a single input connector, available as Phoenix 5‑pin male, sealed EN3 5‑pin male, or sealed ECO‑M 7‑pin male (two pins for DC power, three pins for balanced audio). The audio input shall be electronically balanced with a 10 kΩ impedance and accept a nominal –8.0 dBV (0.4 V rms) input signal.
Power requirements for the loudspeaker shall be a Meyer Sound IntelligentDC power supply capable of delivering 48 V DC.
All components shall be mounted in an acoustically vented trapezoidal enclosure constructed of premium multi‑ply birch with a slightly textured black finish. The protective grille shall be powder‑coated, hex‑stamped steel with black mesh screen. Rigging shall be three 3/8‑inch‑16 or M10 nut plates. Dimensions shall be W: 6.85 in (174 mm) x H: 18.00 in (457 mm) x D: 7.70 in (196 mm). Weight shall be 17 lb (7.7 kg).
The loudspeaker shall be the Meyer Sound UPM‑1XP.
