Microphone preamp

[rlyach]

Hi,

I don't know if this is the correct place to ask this...but... Can any of the phono preamps be converted to work as a microphone preamp? I would also like to add 48V phantom power. I know the phantom power will be a challenge, but will the rest of the phono preamp be adaptable? I don't have a lot of experience with a mic preamp.

If you can hang in a while we have plans to work on a mic preamp design in 2014. In the meantime, yeah, PJ uses a Seduction with the EQ removed as a mic pre. For phantom you can just build it into a separate box. I've done one in a project box with 5 9V batteries for Romo to use when the phantom from the board at a club is too noisy. It's very simple, just requires a couple resistors for isolation and batteries seem to last a long time. There are schematics on the web

Thanks Doc. I will wait anxiously for the release of your microphone preamp kit. In the meantime we are trying a custom design. We are starting with a circuit from the internet and converting it to a true transformer balanced output. Once the Bottlehead kit comes out I will build one and compare them with the one we built and a commercial one.

Just to let you know... building the stereomour has started me down a very expensive path. I have built several amps now and even designed my own guitar amp. I built it from scratch. I even built the speaker cabinet and drilled my own chassis. I had to have it powder coated somewhere else though. Thanks for teaching me so much with the stereomour kit and this forum.

The stereomour is still sounding great. I listen to it almost every day. I also just ordered a Blumenstein Dungeness subwoofer to go with my Orca'sl. After building several amps I have to say that the Stereomour is the best sounding of them all!
