The Presonus Quantum is a Thunderbolt interface with DC coupled inputs and outputs, that means that control voltage signals can be passed to and from your audio interface. Really opening up the possibilities for connecting up your modular to the computer easily.
The Quantum is also super quick, making latency very low indeed.
We also heard that all Presonus interfaces from now on will be DC coupled!
