JBL CSA 2120 2 x 120w 2-Channel Power Amplifier Commercial Amp 4 Restaurant/Bar

The JBL CSA 2120 is a two-channel power amplifier for commercial and installed sound systems, producing 120 W per channel into 4 or 8 ohms. Two channels let you run separate zones from one box, such as a dining room and a patio, each with its own level. Analog front-end processing keeps setup simple: summing RCA inputs on each channel accept a music source and a second feed without an outboard mixer. The switch-mode universal power supply and convection cooling remove the need for a fan, so the amplifier stays silent in a rack near guests. Load impedance is stable from 2 to 16 ohms, giving you room to parallel speakers on a channel, and signal-to-noise is better than 100 dB for a quiet noise floor at low background levels. Auto-standby mode powers the unit down when no signal is present, cutting energy use overnight. The chassis is plenum rated under UL2043, so it can be installed in an air-handling ceiling space where rack room is tight. At 8.2 x 1.7 x 7 in and under 3 lb shipping weight, it mounts almost anywhere, and a rack mounting kit is included. Use it for background music, retail floors, offices, fitness studios, houses of worship and any low-impedance speaker system.
