Hello Guys !
We are (with a friends) currently designing a monitoring controller based around the chip MUSES 72320.
We already did the control section of the Muses, choice of the input and output, mute ... and almost all the control of the unit.
Unfortunately we're more "computer geek" and not "electronic geek".
So Muses, input and output choice are okay and easy for us to control and to design the circuit.
But we're stuck on the electronic part, Input & output. We'd like it to be a Class A unit and Not a passive unit.
So, what we need is more information about the signal flow we could work on and in the best case help to design this part..
I'm thinking about an op-amp / input amp to get a single ended signal (Class A) with the possibility the trim the input..
and a output amp Class A (and do we need a buffer to drive the output amp?)
There'll be an headphone amp too (will see about that later)
Here the signal flow we thought about.
Not sure about buffer and if it's what we need.
Impedance wanted
Any help will be appreciate and if someone want to join us in the adventure we'll welcome him.
We will share the projet and all schematic, maybe a PCB run, but anyway will release all the files and information here to anyone who want to build this Monitoring Controller.
We have plenty idea of features. But we want to start with only the basics.
We know it's going to be a long project ..
Thank you all !

Impedance wanted
- Balanced Input : 80K - 100K (100k is maybe a bit too high)
- Balanced Ouput : around 300 ohm
- and Later : Unbalanced input
