Thanks Alberto

We can add those features and even have a user customizable RIAA curve as well as the industry standard ones ;)

If all goes well I'm hoping to be setup again before the end of the year. At the moment can only do R&D which I have been busy with. :(

New request for phono input:
I have also a tonearm with mono cartridge with only one channel wired: is it possible to get the mono signal ( only one channel wired ) playing both the speakers?

Many thanks

Yes I will add this to the menu in addition to a channel reversal switch that someone else asked for and was able to temporarily implement using Audioweaver. If you need help with this let me know ;)

Also we have found a new premises to operate from which is much bigger than where we were and we are working on some exciting new projects including a Special Edition of the UPP ;)

cheers
