The Lab Gruppen CMA2402_US1 is a fully integrated commercial mixer-amplifier designed to serve as the central audio hub for small to medium-scale installed sound systems. This all-in-one unit expertly combines a flexible audio mixer, a capable power amplifier, and essential system processing into a single 1U rack-mountable chassis, streamlining installation and reducing component count. The mixer section provides eight input channels, each accepting both microphone and line-level signals via combo XLR/TRS jacks, making it simple to connect a variety of sources such as paging microphones, music players, and background audio feeds. The integrated power amplifier delivers 240 watts per channel into 4 ohms, providing ample clean power to directly drive a pair of low-impedance loudspeakers or, through its built-in 70V/100V transformer, an entire distributed speaker system.

Sophisticated processing tailored for commercial applications is at the heart of the CMA2402_US1's functionality. It features priority logic with adjustable ducking, allowing a designated microphone input to automatically lower the volume of background music for clear announcements. Each input channel includes basic two-band EQ and level control, while global output processing includes configurable limiters to protect connected speakers and precise equalization to compensate for room acoustics. The unit supports flexible zoning, enabling independent level control over two separate speaker zones, which is ideal for managing audio in adjacent rooms or areas like a lobby and a main hall. This level of integrated control allows for a highly tuned and protected audio system from a centralized location.

Built for reliability in 24/7 operation, the amplifier boasts a robust power supply and efficient thermal management. Control and monitoring are facilitated through both a clear front-panel interface with an LCD screen and rotary encoders, and remotely via IP or RS-232 connection for integration into larger building management systems. The CMA2402_US1 embodies a professional, solution-oriented approach by merging mixing, amplification, and processing into a reliable, space-efficient package. It is ideally suited for applications such as retail stores, restaurants, conference centers, and houses of worship where system simplicity, audio clarity, and dependable day-to-day operation are critical requirements.
