PRODUCT DESCRIPTION
- Versatile sound system compatibility The CMA2402 supports both Low-Z (4/8 Ohm) and High-Z (70/100 V) configurations offering exceptional flexibility for diverse audio setups. Each channel has a switchable high-pass filter to maintain sound quality and avoid transformer saturation in constant voltage systems. This adaptability makes it ideal for various environments from small venues to expansive spaces requiring distributed audio. Easy installation and flexible placement Designed for straightforward installation the CMA2402 comes with rubber feet for desk or shelf placement plus brackets for wall or under-surface mounting. Optional rack hardware allows one or two units to fit within a standard rack space adding to its versatility. Whether youre setting it up in a tight space or a large AV enclosure this amplifier adapts to your needs. Energy-efficient operation With Auto Ramp circuitry the CMA2402 powers on instantly when an input signal is detected and enters sleep mode after 20 minutes of inactivity reducing energy consumption. Its efficient power-saving design makes it cost-effective to operate while still delivering high-quality sound for extended periods. Intuitive controls and remote operation The front panel features simple yet effective controls including a power button and master volume knob for quick adjustments. Bass and treble controls are accessible with a tool for precise tuning. Remote volume control options via RJ-45 enable easy integration with wall-mounted or tabletop controllers ensuring seamless operation in any setup.
