Professional Power Amplifier
KM-A200-A400
Category: Boardroom
Available as the 2 x 200W KM-A200 and the 2 x 400W KM-A400. The power transistors of this device are arranged in an unequal spacing, which effectively utilizes the heat sink and makes the product's heat dissipation efficiency higher. It uses a brand-new parallel + tunnel type air cooling system, which makes the product's heat dissipation efficiency higher, the overall operating temperature lower, and the product's stability and reliability higher. It uses a brand-new Class H circuit with a 2-level power supply, which makes the product's output effective power higher, the overall operating temperature lower, and the product's stability and reliability higher. It also features advanced protection functions and an output method with a higher damping coefficient than traditional methods.
