The D 500 DUO is a 500 Series receiving frame unlike any other. Balanced analog inserts jacks are provided. When two preamp modules are loaded in the rack, the inserts can be used to connect processors like compressors and equalizers. The insert return signal comes before the output jack. If no processors are inserted, the insert send can be used as a secondary output for the module. The S/PDIF output derives its signal post-insert. This allows for a processed mic pre signal to be converted to digital and sent to a DAW or digital recorder. Analog and digital outputs are always active.
The S/PDIF I/O also allows digital signals from a DAW to be sent to the rack, converted to analog, processed by whatever modules are present, converted back to digital and have the signal returned to the DAW. An Analog/Digital input source select button is provided on the front panel.
BNC I/O allows the D 500 DUO to be a clock master or a clock slave for a larger digital system. The internal clock generator is extremely solid. The internal A/D and D/A can both operate at up to 24-bit/192kHz. A front panel button allows you to toggle through clock sources and sample rates.
The Link button provides stereo linking for capable compressor modules.
The Chain button sends the output of module one to the input of module two, providing an easy way to send the output of a mic pre to the input of a compressor without the need for a patch cable.
