JBL NCSMA180-U-US Compact Mixer Amplifier
The JBL NCSMA180-U-US is a compact 1U half-rack mixer amplifier built for live sound crews and venue operators running permanent or semi-permanent systems. Its fanless design runs silent during performances and requires zero maintenance, making it dependable for control rooms, small to mid-sized venues, or distributed audio installations. Built on Crown DriveCore technology, this unit delivers reliable 80W amplification in a footprint measuring just 8.2" wide by 7" deep—small enough to fit in any equipment rack without adding bulk.
Design & Build Quality
The 1U half-rack form factor with fanless design slides into standard racks without generating hum or fan noise during live events. Its compact footprint (1.7" height, 8.2" width, 7" depth) fits into tight rack spaces, and the universal power supply (100–240 VAC, 50/60Hz) keeps it operational anywhere in the world—no power conditioning headaches.

This mixer delivers 80W of amplification capable of driving both 8 ohm and 4 ohm loads, with seamless compatibility for 70 volt and 100 volt distributed audio systems without requiring external transformers. Four input channels accept balanced mic/line inputs and unbalanced RCA inputs, while illuminated control rings on each channel and master volume knob keep you in control during low-light venue setups or darkened control rooms.
