Hello, I was once set up to do voice over work, maybe 20 years ago. I ended up not continuing with it, and now I would like to set up to record music that I play. I have some old equipment that, honestly, I don't remember what the function of it is! I have an Alesis RA100 amplifier, and Echo MONA 24/96 digital studio, and two mics. The mics are both Audio Technica, 4051a and 4033a/SM. The mics have the three pronged plug. This is old stuff, but I am wondering if I can still use it, or if I should just ditch it and go all digital. Any of your thoughts will be appreciated.
