I wonder if the problem might be a basic impedance mismatch; the cassette
recorder is probably high impedance and the microphone may be low
impedance.


** Lotsa cassette decks have dedicated mic inputs ( often on the front)
using 1/4 inch jacks - these normally work well with internal battery
powered electret mics.

The RCA line inputs on the back do not have adequate gain or the low self
noise needed for use with mics - that is unless you don't mind yelling.
