Talking 8 channel pre FINISHED!

Hey everybody!

This is my first post. I'm a DIY audio enthusiast and I just wanted to show off an 8 channel mic pre that I built from schematic. It's based on the THAT1512 chip.





It's really quiet and really clean. I used the datasheets for the THAT1512 and a power supply that I got from Elliott Sound Products to make it.

It's finally all put together AND it doesn't smoke when you turn it on anymore! YAY! lol

I'll bet the solderheads over at Prodigy Pro would like to see this.

Did you use a schematic floating around, or is it your own design?

Cool

moracspace, I Emailed you.

travis, I just used the "Recommended schematic for use with phantom power" that's on the datasheets for the THAT1512.

switches

Hey... lemme ask you guys something...

This preamp features a stepped gain rotary switch, a light up phantom power switch, and that other silver switch...

What would you rather have that other switch do;

Pad?

or

Phase reversal?



Thanks,
~Dave

Pad, most of the 8 channel units I've ever used I used for drums and I really like having pads on my drum pres. I rarely find myself using the phase switch on anything I use. That may just me be though.

pad vs phase

Well, I'm kinda out of room on the front panel layout and I'd rather not go to a 2 rack unit case. So, it looks like I'm going to have to pick one or the other.

For the prototype you see here I made them pads because if you have a REALLY hot mic you want to use, but don't have a pad, you're kinda SOL (unless you happen to have an inline pad with you). Whereas you can do phase reversal easily within your DAW or using the phase button on your console if you're going all analog. BUT there are guys who I've talked to who insist this should be a phase switch.
