JBL Commercial debuts Drive Core mixer/amps
JBL Commercial is expanding its lineup with the introduction of its CSMA mixer/amplifiers, five models that incorporate Crown’s DriveCore amplifier technology. The new units are aimed at environments such as restaurants, retail stores, conference rooms and smaller houses of worship.
The five models in the line are the CSMA2120, CSMA280, CSMA240, CSMA1120 and CSMA180. The CSMA2120, CSMA280 and CSMA240 are all eight channels in/two out and feature 120W, 80W and 40W outputs respectively. The CSMA1120 and CSMA180 are both four in/one out and offer 120W and 80W power outputs respectively.
All CSMA models incorporate Crown’s proprietary DriveCore amplifier IC chip. The DriveCore chip combines the amplifier driver stage into the power output stage along with additional audio-signal functions. All models can drive 8-ohm and 4-ohm loads and can be used with 70V and 100V distributed audio systems without the need for a separate transformer. All feature a universal power supply which enables the ability to accept AC voltages from 100V to 240V AC, 50/60Hz.
The CSMA mixer/amps offer a clean front panel featuring only volume controls for each channel, master volume adjustment, adjustable bass and treble controls and a power switch. All the volume controls are surrounded by an illuminated ring, making them easy to see and operate in darkened environments. In addition to balanced mic/line inputs, unbalanced RCA inputs and speaker connections, all units include RJ-45 connectors for use with JBL CSR-V in-wall volume controls.
