The BA-2350D Class-D two-channel power amplifier uses switching power technology for high efficiency (up to 85%) and minimum power consumption, saving rack space and running cooler for a longer service life. With a rated output of 2 × 350 W, it can serve as a two-zone, multi-source public address system at minimum cost. Its 100 V high-impedance and 4– 16 Ω low-impedance outputs suit both fixed PA installations and hi-fi stereo systems.
