Hi Folks,
As I mentioned in another post, I'm currently putting together a summing mixer. The original design (from DIYRE) was balanced and passive. However, I thought the unit would be better if it included a make-up gain stage. The gain stages I've considered so far all take a single (unbalanced) input.
Am I right in thinking that if I want to keep the unit balanced-in-and-out, then for Left and Right channels I need to unbalance -> amplify -> balance?
This complicates the build quite a bit as it means that I need the four stages to handle the balancing. From what I can also see, these in turn require a mains PSU. Is that right?
Could I just feed the +ve balanced signal into the amp? I realise that this unbalances the inputs and that I'll lose the benefits of balancing, but will it work?
Cheers,
Chris
