    That microphone is a condenser type.
    It's output is reaaaaaaaaaaaally low.
    You would need a mic per-amplifier that can power the mic and amplifier the low level to a level that standard Amplifier input requires

    See here and learn or make one

    How did you connect it? Can you please post a photo of a hand drawn or computer drawn circuit and a photo of your assembly?
