I think your Mag input is intended for an MM cart., so if you are running it striaght in, without a separate phono stage, that is correct. If not, you may be phono amplifying your phono stage, which should amount to an unacceptable amt. of gain and is thus noisy. The Head Amp input would make sense as an MC circuit, but I am not certain about it. Can you download an SP-4 user manual?
