Hi,
I am building an sound isolation cabinet and will be adding an external balanced and unbalanced mic output. Does anyone know of any chip(s) that I can use to buffer the signal to reduce attenuation that takes both phantom power and/or external power. I don't mind getting a small pcb made but do not want to have to do much work in designing the circuit. I simply want to provide the best output of the box I can and buffering the signal should help in some cases. I'm more interested in building the cabinet than a circuit though. Surely there are ic's made for this job?
