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.Features4 inputs with 1 output of 120-watts of powerIdeal for commercial and industrial useFanless, space-saving 1U designSleek industrial look with illuminated rings, making them easy to see and operateEuro-block type mic/line input connectors and output connectorsIndependent Bass and Treble controls for each output channelSupports 70V and 100V distributed audio systems without the need for a separate transformerRemote volume control capability using JBL CSR-V module and standard Ethernet cablePriority mutingConfigurable output routingUtilizes Crown’s DriveCoreTM technology providing excellent audio performance with high efficiencyManufactured to lead-free ROHS standards, utilizing recycled metals, and using an energy-saving powder coat processIncludes rack mounting kitThree-Year, No-Fault, Fully Transferable Warranty completely protects your investmentEnergy Star® CertifiedSpecsOutput 120W @ 4/8 Ohms (1kHz Power, THD+N<0.5%Frequency Response +/- 1dB (@1W into 4 or 8 Ohms)Load Impedance Stable from 2 - 16 OhmsSensitivity 1.4VrmsSignal to Noise Ratio Greater than 100 dB - 1kHz, A-weightedInput Impedance Balanced 20K Ohms/Unbalanced 10K OhmsMax Input +20dBu TypicalIncluded Accessories Rack mounting kitDimensions 1.7" x 8.6" x 11.9" (43.3 mm x 218.5 mm x 303.4 mm)Shipping Weight 180: 9.9 lbs (4.5 kg); 1120: 10.1 lbs (4.6 kg)
