I have BM800 condenser microphone which produces really low volume because it needs to be connected to a phantom power, I don't have a phantom power but I have an old Pioneer SA-600 amplifier.

How do I connect my condenser mic to this amplifier then to my PC for better recording?

  • It's not because the other post uses a phantom power which is much simplier. – Kevin Bryan Sep 22 '19 at 12:08

    The answer to the other post is how to make it work. Attempting to strap it to a 70's hi-fi amp will not. – Tetsujin Sep 22 '19 at 12:18

    I disagree. Condenser microphones are not home hifi. – Hobbes Sep 22 '19 at 14:38

Consumer amplifiers cannot be used to amplify a microphone.

  1. the signal level produced by a microphone is much lower than the level expected by the inputs on the amplifier. The difference is ~ 30-60 dB, which is a huge amount.
  2. A condenser microphone has some electronics built in which need to be powered. This power is supplied as 'phantom power' by the device you connect the microphone to.

What you need is a device that supplies phantom power. This can be a mic preamplifier or a mixer, but both of those output a line signal you have to get into the computer. In your case, a computer audio interface with a microphone input, as Tetsujin's answer dscribes, is the easiest way to get what you want.

  • Can I use a phantom power that supplies power only then use an external sound card? will that boos my condenser mic? – Kevin Bryan Sep 22 '19 at 12:58
  • The 'external sound card' might as well be the device that supplies the phantom power. Please see the duplicate question, which answers all of this already. – Tetsujin Sep 22 '19 at 14:40
  • Sound cards usually expect a line-level signal. To generate that, you need a microphone preamplifier (and you need one that can supply phantom power). – Hobbes Sep 22 '19 at 14:40
