Pro USB

The Pro USB solution is the ultimate solution for computer audio playback. It provides the ease of a USB interface with the added 100% electrical isolation, long cable lengths, data protection and synchronous interface of the MSB ProISL. By using the ProISL interface the source can be located physically far away from the system and a single fiber cable (up to 1km) can connect to the DAC. This removes the need for network cables in the system setup. The advantage of moving the source far away from the system is much lower electrical noise in your listening room.

Advantages:
– Fully synchronous to the DAC
– Offers 100% electrical isolation between source and DAC
– Works with most music server and computer systems that support USB audio
– Uses the ProISL interface with error correction and detection
– Virtually limitless in cable lengths (up to 1km) between the USB module and the DAC
– Works at rates up to 24/768kHz and 8xDSD (with a PC)

Limitations:
– Offers no control of the DAC from the host source (Volume, etc…)

Multi-part solution.
The Pro USB is one part of a multi-part low noise USB solution. It converts the USB signal from your computer into MSB’s proven proprietary Pro ISL format. The full connection requires the following:

– Roon Core / Server / Computer
– Current generation MSB DAC
– Pro ISL Input Module
– Pro ISL cable
– Pro USB

– 768kHz PCM Playback
– 8x DSD support*
– Full MQA decoding*
– 100% Electrical isolation between the DAC and server/computer
– Uses the audio clock from the DAC
– Supports ProISL cable lengths up to 1km without any loss
– Requires ProISL Input module in the DAC
– Will only work with current DACs (Discrete, Premier, Reference, and Select)
– *8x DSD and MQA support require firmware updates in the DAC

– Fully synchronous to the DAC
