Note:  the UH7000 is not included in this auction. This is for one of two available digital converters.  

Power supplies are included. 

You can hear them in action with these vids of mine:

NOTE!!! IMPORTANT!!!!

One of the knobs are missing on one but you can still turn it.  The one with the knobs intact will be sold first. 

• These open up digital inputs on many audio devices.  Eg on the Tascam UH7000 I was able to double the mic inputs by using these with two preamps.
