CSMA 2120 2x120W Amplifier + (4) White Column Line Array Speakers

The JBL CSMA 2120 mixer-amplifier and four Rockville WET ARRAY 4 white column speakers combine into a higher-output distributed sound system for restaurants and bars that need more coverage than a basic wall speaker setup. The two-channel unit powers 8 and 4 ohm loads directly and supports 70V and 100V distributed audio without a separate transformer, all from a fanless, one-rack-unit chassis built around Crown’s DriveCore technology. Balanced mic and line inputs, unbalanced RCA inputs, and RJ45 support for an optional JBL CSR-V wall controller round out the connections.

Each WET ARRAY 4 speaker uses four 3.5" full-range drivers in a high-grade aluminum enclosure rated IP66 for water resistance, holding up to installation indoors or in covered outdoor areas. A 4-way swivel wall bracket lets you angle each column toward the seating area, and a rear tap switch selects 10W, 20W, or 40W of 70V power, or an 8 ohm setting for direct wiring. Running four of these column speakers off one two-channel mixer-amplifier gives a restaurant or bar noticeably more throw and clarity for both music and PA announcements than a standard set of ceiling or wall speakers, while keeping the electronics down to a single rack unit.
