Mixer Amplifiers

Designed for commercial and industrial use, the CSMA 280 Commercial Series Mixer/Amplifier from JBL is a mixer/amplifier with eight mixer-channel inputs and two output channels. It's capable of reaching 80W of peak power with 10W per channel. The unit's front panel sports volume controls for each channel, as well as two master volume adjustment knobs, two sets of bass and treble controls, and a power switch. The volume controls are illuminated so they can be seen and operated in darkened environments.

The amplifier, capable of driving both eight and four Ohm loads, can be used with 70V and 100V distributed audio systems without the need for a separate transformer. On its back panel you'll find euroblock connections for mic/line inputs, as well as unbalanced RCA inputs, speaker connections, dip switches for input routing, and more. The unit is also equipped with two RJ45 connectors for use with JBL CSR-V in-wall volume controls (available separately).

This Commercial Series mixer/amplifier boasts such features as voice activating ducking (useful for paging over background music), priority muting for channels one and five, and a sleep mode which automatically powers down the unit when no audible signal has been received for longer than 30 minutes. Also, with two auxiliary outputs, you may connect to an additional amplifier, though the master volume and tone controls will have no bearing on the resulting signal.

The JBL VMA2120 is a Commercial Series Bluetooth-enabled mixer/amplifier designed to provide flexible multi-source mixing and amplification for installation in restaurants, educational institutions, fitness centers, and retail stores. It features an 8-in/2-out mixer and 120W of output power. It can be installed in a standard 19” equipment rack with the supplied rackmount kit or set on a surface such as a desk or ledge.

Stream music wirelessly via Bluetooth or connect a USB drive to the front-panel USB Type-A port. Route other sources via Euroblock, RCA, and 1/4" input jacks. The integrated mixer offers level controls as well as bass and treble for each channel. Routing to the Euroblock outputs is configurable. The VMA2120 supports voice-activated ducking and priority muting. The front-panel controls and display make operation easy, and remote volume control is possible via a JBL CSR-V module and a standard Ethernet cable (both available separately).
