Re: Anyone make a preamp / compressor combo unit?

Thanks for the explanation. It was my first assumption that the plot is a result of using an 2604 here. Will exchange them with DOAs.

Re: Anyone make a preamp / compressor combo unit?

Thanks Joe. I've recently went to a local EE audio company to get some test results for the combo unit. The BabyAnimal has an EIN of -117 dBU at max gain, 20-20000 Hz, 150 Ohm terminated. This is, IIRC, 10 dBu worse than the theoretical possible EIN of -127 dBu. Here's the AP plot for the BA (Lundah...

Re: Anyone make a preamp / compressor combo unit?

Q: Anyone make a preamp / compressor combo unit? A: Yes, me. Built it for a local musician for his home studio. He wanted a dual pre/compressor unit, I left out the first PreAmp because he decided to buy a tube preamp for his voice channel, so this is a one PreAmp/two compressor unit with an option ...

Re: INX5 BUILD THREAD

I've decided to make a new front panel for my MAC 500. Custom painted green, looks a bit like an old Altec device :wink: http://audiofor.tv/diy/mac%20500%20green/IMG_1488.jpg http://audiofor.tv/diy/mac%20500%20green/IMG_1495.jpg I can recommend to buy one of Joe's compressor kits.

I finished my first INX5 today, used here for a MAC with a nice Haufe transformer.

BA on +/- 24V

Is it possible to run a BA on +/- 24V just as a gain stage with input transformer and DOA ? I don't have 48V in the box I'm currently working on.

Joe, for those who alredy built their meters, can you indicate the position of the relevant components on a photo?

Re: Coming Soon New 40 Led PPM/VU/GR Meter kit with Peak hold

Chris, I agree, it's a big meter. But I see the beauty in the logic behind it. Joe uses the big dual/triple colour LEDs, I assume that it would be possible to use smaller, single colour LEDs later, thats why I'm wondering about different modes. So, once Joe and his team has developed the software fo...
