CSMA1120 Mixer Amplifier + WiiM Pro Plus Streaming Kit

This kit pairs the JBL CSMA1120 commercial mixer amplifier with the WiiM Pro Plus streamer, giving restaurants, bars, cafes, retail shops, and offices a complete background music system that plays straight from a phone, tablet, or voice assistant. The CSMA1120 delivers 120W from a fanless 1U chassis, so it fits a single rack space and runs silently in a back office or equipment closet. It powers 4- or 8-ohm speakers directly and connects to 70V or 100V distributed systems without a separate transformer, which keeps a multi-speaker ceiling install simple. Four inputs accept balanced mic/line or unbalanced RCA sources, and priority muting lets a paging mic cut through the music when staff need to make an announcement.

The WiiM Pro Plus turns that amplifier into a streaming system. It supports AirPlay 2, Chromecast, Spotify Connect, TIDAL Connect, and DLNA, and works with Alexa, Google, and Siri, so anyone on staff can change the playlist from the app or by voice. Hi-res playback reaches 192kHz/24-bit through an AKM 4493SEQ DAC rated at 121dB SNR, and the included RCA cable runs directly into the CSMA1120's RCA input. Multiroom grouping, a 10-band graphic EQ, and gapless playback round out the streamer side.

Front-panel volume knobs with illuminated rings stay easy to read in a dim bar, independent bass and treble controls let you tune the sound to the room, and RJ45 ports accept JBL CSR-V in-wall volume controls for adjustments away from the rack. A rack mounting kit is included.
