CSA140Z 70V Amplifier + (4) DCS8T Drop Ceiling Tile Speakers

This package pairs the JBL CSA 140Z 40W Commercial 70V Amplifier with 4 Rockville DCS8T 8" 70V Drop Ceiling Tile Speaker speakers, giving offices with standard 2' x 2' drop ceiling grids a complete 70V sound system without sourcing amp and speakers separately. The JBL CSA 140Z anchors the system with a single 40W channel built on Crown's DriveCore technology, which replaces hundreds of discrete parts with one chip to cut down on points of failure while keeping the sound clean. Built-in 70V and 100V operation lets it power a distributed system straight out of the box, and a universal power supply accepts 100 to 240 VAC so it works on nearly any electrical service. The fanless 1U rack design stays quiet enough for a dining room, and a sleep mode disable function keeps the amp always ready for paging or background music. The package also includes the 4 Rockville DCS8T tile speakers, each an 8" driver pre-mounted into a standard 2-foot by 2-foot drop ceiling tile. Installation is a straight swap: pull the existing tile, drop this one in its place, and connect the speaker wire. A rear-mounted tap selector switches between 10W, 5W, and 2.5W on the 70V line or 8-ohm operation, and the tuning favors both spoken announcements and background music. Because both pieces are matched for 70V operation, wiring the 4 speakers to the amplifier is a matter of running positive and negative leads with no impedance math, and the amp's power still has headroom for expanding the zone later.
