GENERAL INFORMATION

The DS1390 plenum masker is a complete loudspeaker assembly ready for installation, in an open

structure office facility or above suspended ceilings. The unit is composed of an six-inch diameter

loudspeaker, metallic back box, 70V transformer, and volume control. The unit should be wired to a

power amplifier with a 70.7 V output.

UNPACKING

The Plenum Maskers are carefully tested before leaving the factory. Inspect both the units and their

shipping container for indication of improper handling. Report any equipment damage to the distributor

immediately. If the unit was shipped to you, notify the shipping carrier without delay and place your

claim.

Ladder, Wire strippers, Crimp Connectors, Flat headed screwdriver, others depending on at

tachment method

Hanging wire or chain as preferred

18 Gauge twisted pair wire for electrical connection

MECHANICAL INSTALLATION

The DS1338's eyebolt provides a single point suspension. Determine the correct method for

attaching the hanging wire to the structure above the ceiling. Typically the method used to hang

ceiling grid is the best for speaker installation. For example hangers can be shot into concrete

structures or suspension wire can be wrapped around bar joists in metal ceiling structures. Set

the volume control on each speaker at 1W (One Watt). Determine the locations for the speakers

and open the appropriate ceiling tiles. Inspect the plenum for places to hang the speaker. It is

always preferred to independently hang the speaker assembly. Cut a length of hanging wire

such that the speaker may be hung from the chosen location.
