Protea is compatible with Microsoft® Windows 8, 7 (Vista/XP) 32 & 64 bit systems.

Audio professionals find our Protea™ DSP to be very

intuitive and easy to navigate—and you will too. No

need to attend a one-week training class away from

home to learn our software. Common sense layout

of controls and features, on-line help, or a visit to

the Technical Support page on our website provides

answers to all of your questions.
