JBL Professional CSA-180Z - Commercial Amplifier 1 × 80 W with 70/100 V and 4/8 Ω outputs (DriveCore™, 1U fanless)
The JBL Professional CSA-180Z is an 80W mono amplifier designed for background music and announcements in retail, hospitality, education, and corporate spaces. Based on Crown's DriveCore™ technology, it offers high efficiency and quiet operation in a fanless 1U chassis. It features an integrated transformer for 70/100V lines with Hi-Z switching and an automatic 70Hz subsonic filter; it can also operate at 4/8 Ω in low impedance. Connectivity options include a balanced Euroblock input and stereo RCA input plus mono input, bass and treble controls per channel, and an RJ-45 port for remote CSR-V volume control. Energy Star® certified and powered by a 100–240V universal power supply, the CSA-180Z simplifies integration and reduces power consumption.
