Model VM-EX2100/VM-EX2200/VM-EX2300/VM-EX2400/VM-EX2500/VM-EX2600/VM-EX2800

Product Overview
VM-EX series covers seven models from VM-EX2100 to VM-EX2800 with graded power outputs, delivering stable RMS power at 8Ω/4Ω and reliable bridged power for diverse audio scenarios. Equipped with a front panel display and 4Ω/8Ω quick impedance switching, they feature rear XLR balanced and 6.35mm mono jack inputs. Built-in DIP switches support limiter control, bridge/stereo mode and ground/lift switching. The series offers adjustable electronic crossover frequencies and comprehensive protections against short circuit, overheating, overload, undervoltage and DC output. Boasting 10Hz-20kHz frequency response, low THD below 0.1% and high signal-to-noise ratio, these rack-mounted amplifiers support 115V-230V AC input, ensuring stable, high-fidelity professional audio performance.
