Add to cart USB Disruptor Type B $199.00 USB Disruptor includes a USB Type B adapter. The adapters are interchangeable making USB Disruptor compatible with any USB DAC. We include a specially designed ultra voltage stable power supply with overheat and short-circuit protection. An LED light on the Disruptor circuit board indicates power is active. The external casing is injection molded polymer that accomplishes two goals: it’s lightweight and does not conduct a current. This makes mounting the unit to your DAC possible, if the unit is too heavy it could damage the USB input on your DAC.
