FP11 line preamp self noise

Date Updated: March 2, 2018 FAQ #533
Question:
I've recently purchased a pair of the Shure FP11 mic line preamps. I've noticed self noise (hiss, static) added to the mix. Currently, I am running a pair of condenser mics through the FP11's into a Sony DAT deck. I have troubleshot the cables, equipment, etc. and have found that this interference is coming from the FP11. Any ideas of ways to remedy this problem?
Answer:


Being an older design, the FP11 would need to be completely redesigned to lower its self noise. Sound Devices is a company that sells a low noise preamp, like the FP11. The model is MP-1.
