The purest and most tangible audio experience
Digital Series DS20
Excellent sonic performance class-D design
High power and very pure signal amplification under heavy user conditions were the main goals in the development of the DS Series amplifier range. These (mono block) power amplifiers are built with an excellent sonic performing classD design for increased efficiency by decreased weight and dissipation. With an output power exceeding 700W @ 4Ω per channel, a S/N ratio of more than 110dB and a THD percentage of < 0.007% @ 1kHz (100W, 8Ω). The DS20 combines (sound)quality, power and very low weight into one unit. Each audio channel has its own power supply. The SA digital amps are among the best sounding digital amps on the pro-audio market!
