CSMA240 Mixer Amplifier + White CSR-V Controller

The CSMA240 is an eight-input, two-channel mixer amplifier built for restaurants, retail stores, and other commercial and industrial spaces that need background music and paging from one compact unit. Each output channel delivers up to 40W into 4 or 8 ohm loads, and the built-in output transformer lets it power 70V or 100V distributed speaker lines directly, so you can cover a large floor plan without adding a separate transformer. Euroblock mic/line inputs, six dual RCA inputs, and switchable 27V phantom power handle microphones, music players, and other sources in a chassis just 1.7 inches tall.

Voice-activated ducking on channels 1 and 5 lowers background music automatically when someone speaks, and priority muting cuts all other channels for announcements, even waking the amp from sleep mode. Independent bass, treble, and volume controls for each output let you tune two areas separately, and the illuminated knobs stay easy to read in a dim back office. Sleep mode powers the unit down after about 30 minutes without signal, and the amplifier carries Energy Star certification.

This kit also includes a white CSR-V wall volume controller at no extra cost. It connects to the amplifier's RJ45 port over Cat 5 cable at distances up to 1,000 ft, so staff can adjust the volume from the dining room or sales floor instead of walking back to the equipment closet.
