Hi all,
I need help. I am getting back into building again. But I am not looking for a therapist. At least not yet.
When I looked at my box full of audio measurement stuff I remembered the pia it is to drag cables and amps and pre-amps around. So I decided to come up with a simple test box that includes a chip amp and a mic pre-amp. I checked the web and found a bunch of complicated projects. I want simplicity at my advanced age. So I have come up with a simple design I'd like you to peek at and check for errors. Heck, make suggestions too.
I am going to use a chip amp to drive the DUT and I have a couple mic pre-amps on perf board I can use for dynamic mics. But I also want to use my ECM 8000 with its pre-amp. I will use an out board resistor for impedance measurements. That makes things much simpler. This design uses only two switches and two pots. I will be using ARTA. Hopefully the attached schematic is clear.
Thanks
