SDA1 – Studio Digital Amplifier


The extremely efficient Class-D topography used in the ART SDA1 Studio Digital Amplifier delivers 200 watts per channel (at 4 ohms) in a compact, single rack space chassis. Taking advantage of the full potential of digital amplifier design, the SDA1 doesn’t require noisy, dust collecting cooling fans in operation, making it the ideal solution for studio control rooms and installations.
