The STK new DC series AMPLIFIERS ARE PROFESSIONAL TOOS DESIGNED WITH FULL DIGITAL TECHNOLOGIES.
Have high efficiency output design with the universal switch-mode power supply that reduced weight while increasing power outputs.
The class-D amplifier topology is very efficient,making the DC series amps small and light. Products benefit from the proven best reliability STK VS series digital power supply.
The DC amplifiers power levels are matched to the most popular passive speaker systems.
