Radio Systems, Inc. - DA-AD - Digital to Analog, Analog to Digital Converter

Radio Systems' new analog to digital converter is a broadcast quality device optimized to provide flexibility along with super high quality conversion of analog and digital signals.

The D-A+A-D is actually 2 stereo converters which can provide simultaneous conversion of analog to digital and digital to analog signals. Features include:

24 Bit resolution
Variable sample rates to 96kHz
Internal and external clocking
Auto sync to external clock input
Auto sample rate sensing
XLR and RJ-45 connectors (StudioHub+ standard)
