MSB Pro USB Adapter

The Pro USB is a USB to ProISL adapter. This allows you to play music from a computer or server via USB into our DAC via our isolated, clock synced ProISL interface. The benefits of this system are mainly be for isolation of noisy computer solutions. Using any length (up to 1km) Pro ISL Cable, the computer/server can be removed from the audio system. This removes the need for network cables in the system setup. Features
