The JBL® CSMA series of Mixer-Amplifiers represents a cutting-edge solution for commercial sound applications, blending professional-grade performance with a sleek, industrial design. Engineered with the latest advancements, these mixer-amplifiers utilize Crown’s DriveCore technology, which drastically reduces their size and weight while maintaining high efficiency and reliability. The entire CSMA series is fanless and occupies just 1U of rack space, making it an ideal choice for installations where space and quiet operation are at a premium.

Available in both single-channel and two-channel models, the CSMA series offers flexibility with four or eight mixer channels, respectively. This range of configurations ensures that there is a model suitable for various applications, from small venues to larger commercial installations. The clean front panel design of the CSMA mixer-amplifiers ensures ease of use, featuring only essential controls: individual volume knobs for each channel, a master volume control, adjustable bass and treble controls, and a power switch. Each volume control is encircled by an illuminated ring, enhancing visibility and operability in low-light environments.

One of the standout features of the CSMA series is its versatility in handling different types of loads and systems. The amplifiers are capable of driving both 8-ohm and 4-ohm loads, and they can be seamlessly integrated into 70V and 100V distributed audio systems without requiring a separate transformer. This capability makes the CSMA series exceptionally versatile, suitable for a wide range of commercial audio applications.

The connectivity options provided by the CSMA series further enhance its flexibility. In addition to balanced mic/line inputs and unbalanced RCA inputs, the mixer-amplifiers offer speaker connections and RJ45 connectors for integration with JBL CSR-V in-wall volume controls. This extensive connectivity ensures that the CSMA series can be easily integrated into existing audio systems, providing a robust and adaptable solution for various environments.

The universal power supply of the CSMA mixer-amplifiers is another significant advantage, allowing them to accept AC voltages from 100 to 240 VAC, 50/60Hz. This feature makes the amplifiers suitable for global use, accommodating different power standards without the need for additional adapters or converters.

In line with HARMAN’s GreenEdge™ environmental initiative, the JBL Commercial mixer/amps are manufactured to meet lead-free RoHS standards. They incorporate recycled materials such as copper, aluminum, and steel and utilize energy-saving powder coat finishing processes. This commitment to environmentally-conscious manufacturing practices underscores HARMAN’s dedication to sustainability and responsible production.

The highly efficient DriveCore design of the CSMA series not only reduces power consumption but also enhances operational efficiency. These amplifiers are up to 80 percent more efficient than previous designs, translating into significant energy savings and reduced operational costs. Furthermore, all models in the CSMA series come with a 3-year no-fault transferable warranty, providing peace of mind and assurance of their durability and reliability.

In conclusion, the JBL® CSMA series of Mixer-Amplifiers stands out as a professional-grade, environmentally friendly solution designed for the demanding needs of commercial sound applications. With their compact size, high efficiency, and versatile connectivity, these mixer-amplifiers offer unmatched ease of use and flexibility, making them an excellent choice for any commercial audio setup.
