JBL CSA 140Z Commercial 70v Amplifier Amp+(4) 3.5" Black Cube Speakers CSA140Z

This package pairs the JBL CSA 140Z 40W Commercial 70V Amplifier with 4 Cube by Rockville 3.5" 70V Commercial Speaker in black speakers, giving offices and retail counters needing compact background sound 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 Cube by Rockville speakers, a compact 2-way design with a dedicated woofer and tweeter that keeps a minimal footprint on a wall or shelf. A 360-degree swivel mounting bracket lets each speaker rotate for the best sound staging in a small room, and a rear tap selects 6W, 3W, or 1.5W on the built-in 70V transformer. Detachable euro-block terminals make wiring several units at once faster. 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.
