CSMA280 Mixer Amplifier + WiiM Pro Plus Streamer

The JBL CSMA280 is a commercial mixer amplifier for restaurants, bars, retail floors, and offices that need background music and paging from one chassis just 1.7" tall. It delivers 2 x 80W and powers 4 Ohm or 8 Ohm speakers, or connects directly to 70V and 100V distributed speaker lines through its built-in Hi-Z transformer, so a ceiling speaker run across a dining room or sales floor wires straight to the amp with no separate transformer. Eight inputs cover a typical install: mic/line euroblock inputs with 27V phantom power for paging microphones, plus RCA inputs for music sources. Independent bass and treble controls on each output let you tune two areas separately, and the illuminated volume knobs stay readable in a dim room.

Paging is built in. Voice-activated ducking on channels 1 and 5 pulls the music down when someone speaks, and priority muting silences the other inputs during an announcement, even waking the amp from sleep mode. Sleep mode powers the unit down after about 30 minutes without signal, and two aux outputs feed an additional amplifier when the system grows.

A WiiM Pro Plus WiFi streaming player comes in the box at no extra cost, giving the CSMA280 a ready music source on day one. Connect it to an RCA input with the included cable and stream Spotify, TIDAL, Amazon Music, Pandora, and more through AirPlay 2, Chromecast, or the WiiM Home app, with Hi-Res playback up to 24-bit/192kHz. Staff can change playlists or stations from a phone instead of walking back to the equipment rack.
