The MTC-PC2 and MTC-PC3 are simple-to-use protective Panel Covers for the input terminal panel of many models of Control Contractor and Control Series loudspeakers. On MTC-PC2, the wire exits from the rear of the cover, and on MTC-PC3, the wire exits from the side of the cover. The panel cover installs over the existing input cup and provides a watertight gland-fitting entrance to seal and protect this section of the loudspeaker against incursion of water. The cover comes only in black. The cover section is paintable, but the gland nut is not.
