Specifications

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)
