This Preda belonged to @Jim before he switched to the two box TBSP version.
It had less than a year of use, and has been sitting, boxed in my store room but it needs to go.
The Preda is an active line stage constructed around some custom made autoformer attenuators but with Aurorasound’s proprietary gain stages fore & aft. This means that the Preda has no effect on the source component and will not interact with the input of any subsequent power amp. Those are common issues with other forms of passive or inductive volume controls.
The Preda has 6 inputs, (2 Balanced) and single ended or balanced outputs.
