[. . . ] MIS8C Paging and Public Address Loudspeaker General Description: The University Sound MIS8C is a conservatively rated 10watt reflex paging projector designed for flush-mounting. [. . . ] 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.
