Though remarkably compact and lightweight, the UPJunior delivers robust peak power output making it suitable for use as either a single, primary loudspeaker or within multicabinet horizontal and vertical arrays.
Features & Benefits
The loudspeaker shall be a self-powered, full-range system. The transducers shall consist of an 8 in diameter cone driver and a 2 in diaphragm compression driver on an 80° x 50° horn. The horn shall allow rotation to provide the wider coverage pattern in either the horizontal or vertical plane relative to the cabinet’s vertical axis.
The loudspeaker system shall incorporate internal processing electronics and a two-channel amplifier. Processing functions shall include equalization, phase correction, signal division, and driver protection for the high- and low-frequency sections. Each amplifier channel shall be class AB/bridged with complementary MOSFET output stages. Burst capability shall be 580 W total into nominal loads of 4 Ω low channel and 12 Ω high channel. Distortion (THD, IM, TIM) shall not exceed 0.02%.
Performance specifications for a typical production unit shall be as follows: operating frequency range shall be 70 Hz – 20 kHz; frequency response shall be 76 Hz – 18 kHz ±4 dB; phase response shall be 250 Hz – 18 kHz ±45°; linear Peak SPL shall be 123.5 dB measured with M-noise, free‑field at 4 m referred to 1 m. Coverage (–6 dB points) shall be 80° by 50°, horizontal or vertical dependent on horn orientation.
The audio input shall be electronically balanced with a 10 kΩ impedance and accept a nominal 0 dBV (1.0 V rms) input signal. Connectors shall be XLR 3-pin female input with male loop output.
The internal power supply shall perform automatic voltage selection, EMI filtering, soft current turn-on and surge suppression. Power requirements shall be nominal 100 V, 115 V or 230 V AC line current at 50 Hz or 60 Hz frequency. Current draw during burst (< 1 sec) shall be 2.9 A at 115 V, 1.7 A at 230 V and 3.2 A at 100 V. Current inrush during soft turn-on shall not exceed 15 A at 115 V. The AC power connector shall be a PowerCon with looping output.
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 trapezoidal enclosure constructed of premium multi-ply birch with a slightly textured black finish. The front protective grille shall be powder-coated, hex-stamped steel with acoustical black mesh. Dimensions shall be W: 9.00 in (229 mm) x H: 19.04 in (484 mm) x D: 10.20 in (259 mm). Weight shall be 28 lb (12.7 kg). Integral high-strength, 6061-T6 aluminum top plates with threaded M8 metric holes shall accommodate Meyer Sound proprietary rigging hardware and third-party accessories.
The loudspeaker shall be the Meyer Sound UPJunior.
