SDR 1000D Audio Interface to PC

Here is a closer look at the M-Audio interface or breakout box shown in the photo from the last post. M-Audio refers to this breakout box as their Delta series, which is this particular model.

As you can see there are 4 inputs and 4 outputs to the interface. Inputs 1 & 2 are line inputs. Inputs 3 & 4 are microphone inputs.

The outputs 1 & 2 are used to drive a pair of amplified speaker, as would be used for audio from your PC. Outputs 3 & 4 are the line outputs, which I referenced from the last post.

Flex-Radio use M-Audio as one of several "approved" audio interfaces along with an audio card which is installed in the PC. This particular M-Audio interface came with the 1000D when I purchased it, as both the Flex 1000D, and the accessory item were all pre-owned.

The audio interface does not come with any of the old or newer Flex systems, they must be purchased separately, along with the other items required for a complete operating system.

I currently use the speaker outputs to feed a pair of amplified Inland Pro Sound 2000 mulit-media speaker systems. They are moderately priced and have a very good sound quality for HF AM and SSB operation.

On the back side of the interface is the PC type "D" connector which connects to the rear panel of the PC.
