    Don't want to DIY, but where to send a dead mic for repair?

    Does anyone use the microphone input on your Hi-Fi?

    A high impedance microphone input seemed to be pretty common in the early days of Hi-Fi, now, not so much. Does your equipment have this feature? Do you use the microphone input on your Hi-Fi? Example: Heathkit WA-P2 with MIC (Microphone) input

    Trusted Brands for a Phantom Power supply

    I've got a condenser mic and I've been using it without a power supply for a while but it's a bit annoying to use.

    Mic for Sony DSR-PD150 camcorder?

    I've acquired a Sony DSR-PD150 camcorder without a microphone, and I'm wondering what my options might be for a suitable affordable new or used microphone. I tried my Audio Technica AT9100, and it can barely be heard, even with the gain turned all the way up. I'm guessing this is because it's a...

    Another one of my homemade mics, this one is my most elaborate.The element is a headphone speaker going to a passive EQ to get the bass up and that's going to a computer speaker amp to boost the output and act as a buffer.The response is good except for that bump from 2k to 3k, which gives it a...

    I have two of these TEAC ME-50 Electret Condenser Microphones. It seems they take batteries, but the chamber is wider than a AA and I don't want to mess it up by using a battery with the wrong voltage. Does anyone know what battery these things take?
