General Description:
The Electro-Voice ® EVID C4.2 loudspeaker system is a
complete two-way ceiling loudspeaker package. The package
consists of a bezel assembly, grille, rear enclosure, 4-inch coax
two-way loudspeaker and internal line-matching transformer. The
loudspeaker features a waveguide coupled titanium coated dome
tweeter. The EVID C4.2 loudspeaker utilizes a 2
crossover network at 3.3 kHz, with a comprehensive protection
circuit to protect the network, woofer, and tweeter drivers from
excessive power levels. The C4.2 utilizes a transformer that
offers a selection of 1.88 (70-V only), 3.75, 7.5, 15 or 30 watts
delivered to the loudspeaker system using either 70-V or 100-V
lines, or 8 ohm bypass. Selection is via a convenient switch on
the front baffle. The perforated grille is finished in semi-gloss
white powder-coated enamel. The baffle and bezel are
constructed from UL 94V-0 rated ABS. The rear enclosure is
constructed from zinc-plated, heavy gauge steel. The rear
enclosure, with fiberglass damping material, provides an optimum
internal volume for extended low-frequency performance. A rear
cover, with provisions for a junction box fitting, provides access
to a 4-pin terminal block that allows direct connection to the
speaker with 12 gauge wire and provides pass through to
additional speakers. A tile bridge is included for safe suspension
of the C4.2 ceiling systems in a drop ceiling that uses mineral
wool, or other fiber-based ceiling tiles. The EVID line of ceiling
speakers has been designed to work together as a complete
system in a wide range of different ceiling constructions. They
provide wide dispersion, high-efficiency, high-maximum output,
ease of installation, and wide-range reproduction of music or
voice.
