UP-4slim UltraCompact Installation Loudspeaker

The UP-4slim ultra-compact installation loudspeaker is ideally suited for applications requiring a small, slim, aesthetically pleasing cabinet that delivers high sound pressure levels with low distortion, and uniform coverage. The UP-4slim offers this exceptional audio performance in a compact self-powered package with a remote power supply. As a standalone loudspeaker, the UP-4slim is appropriate for vocal reinforcement, front-fill and under balcony fill applications. The UP-4slim can be optionally paired with a Meyer Sound subwoofer to create a full range system. One MM-10ACX can also power one UP-4slim.

The loudspeaker system shall incorporate internal processing electronics and a three channel amplifier, one channel for each driver. Processing functions shall include equalization, phase correction, signal division, and driver protection. The crossover point shall be 1.5 kHz. Amplifier channels shall be class D. Amplifier output power shall be 500 W total for all three channels. 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 65 Hz to 18 kHz; phase response shall be 102 Hz – 18 kHz ±45°; linear peak SPL shall be 116.5 dB measured with M-noise, free field at 4 meters and referred to 1 meter. The horizontal and
    vertical coverage shall be 100°.

    The loudspeaker shall be equipped with a Phoenix 5-pin male connector (three pins for balanced audio and two
    pins for DC power). The audio input shall be electronically balanced with a 10-kOhm impedance and accept a
    nominal -2.0 dBV (0.8 V rms) input signal. Power requirements for the loudspeaker shall be a Meyer Sound MPS-488HP IntelligentDC power supply capable of delivering 48 V DC. Maximum long-term continuous current draw for the loudspeaker (< 10 s) shall be 1.0 A average at 48 V.
