Product Description

The Electro-Voice MIS8C 10-Watt Commercial Sound Paging Projector is a conservatively rated 10- watt reflex paging projector designed for flush-mounting. The driver uses a rugged phenolic diaphragm, a 0.75- inch voice coil and component parts proven reliable under stressful conditions. A dispersion angle of 100° +/-25° is maintained over the frequency range of 1,200 Hz to 3,000 Hz. Excellent loading is maintained to a low-frequency cutoff of 600 Hz. The MIS8C is molded from rugged polycarbonate and the inner reflector from ABS. With it’s weatherproof construction the MIS8C may be used both indoors and outdoors. Designed for low-impedance systems, this compact horn has outstanding speech intelligibility and high efficiency. The directional characteristics of the MIS8C were measured by running a set of polar responses in University’s large anechoic chamber. The test signal was one-third-octave-bandlimited pseudo-random pink noise centered at the ISO standard frequencies indicated in Figure 1. Additional typical data is provided in Figure 2 which indicates 6-dBdown beamwidth versus frequency for an MIS8C. Figure 3 shows the axial frequency response of the MIS8C horn. It was measured at a distance of 1 meter, using a swept sine wave. Six holes around a 4.87 in (12.4cm) diameter circle provide a means for fluch mounting the speaker. When frequencies below the low-frequency cutoff for the horn assembly are fed to the driver, excessive current may be drawn by the driver. For protection of the driver and amplifier, capacitor in series with driver is recommended. For drivers without transformers: 8-ohm driver, 25V- 100 mf 4-ohm driver, 25V - 200 mf 150V dc or 150V non-polarized electrolytic, or two 150V electrolytics of two times required value in series, back to back, for 70V lines.
