CSA140Z 70V Amplifier + (4) MC80 Ceiling Speakers

This commercial audio bundle pairs the JBL CSA140Z 40W amplifier with four Rockville MC80 8" metal ceiling speakers, giving restaurants, bars, retail stores, offices, and schools a ready-to-install 70V system that spreads background music and PA announcements across a larger floor plan. Four speakers let you cover a dining room and entry, a sales floor and checkout area, or a row of connected classrooms from a single amplifier. The CSA140Z runs 70V or 100V lines straight out of the box, so you wire every speaker in parallel without calculating impedance, and its fanless 1U chassis fits in a rack or on a shelf without adding noise to the room. A universal 100 to 240V power supply and Energy Star certification keep it practical for long daily runs, and the RJ45 port accepts a JBL CSR-V wall controller if you want volume at the wall later.

Each MC80 uses an 8" dual cone driver rated 70Hz to 20kHz with 90dB sensitivity, so speech stays clear and music carries more low end than smaller 6.5" ceiling speakers. Taps at 5, 2.5, 1, and 0.5W on 70V let you set each speaker for its zone, such as 5W over the main floor and 1W in a hallway or restroom, and the volume knob hidden in the grille center lets you fine tune output without pulling the speaker from the ceiling. With all four speakers tapped at 5W, the system draws 20W, leaving the amplifier headroom for more 70V speakers as your space grows.
