CSMA 240/280/2120
The JBL® CSMA series of Mixer-Amplifiers are a professional
tool with a sleek industrial look that is designed and built for commercial
sound applications. Utilizing Crown’s DriveCore
technology enables significantly reduced size and weight – all mixer/amps
are highly efficient, fanless and just 1U rack space
high. There are both single channel and two channel models with four or eight
mixer channels, respectively.
The
CSMA mixer/amps offer unmatched ease of use, with 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. The amplifier 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. In addition to balanced mic/line
inputs, unbalanced RCA inputs and speaker connections, all units include RJ45
connectors for use with JBL CSR-V in-wall volume controls. All models feature a
universal power supply which enables the ability to accept AC voltages from 100
to 240 VAC, 50/60Hz.
JBL
Commercial mixer/amps are manufactured under HARMAN’s GreenEdge™
environmental initiative, conforming to lead-free RoHS
standards and utilizing recycled copper, aluminum and steel, an energy-saving
powder coat finishing process and other environmentally-conscious manufacturing
processes. Their highly efficient DriveCore design
reduces power consumption and yields much more efficient operation – up
to 80 percent more efficient than previous designs. All models carry a 3-year
no-fault transferable warranty.
