Hi All,
I have a PreSonus ADL 700 with a loud, white noise with crumpling paper in it when I
use the instrument input.
I have been using the mic input for guitar and bass since Ive had it, although if I tweak the EQs
more than 2oclock I can hear a hissing coming back in .

Anyone had this sort of problem ?

Neumann M147 tube + Avalon 737sp
Neumann u87 + Vintech X73i
or
Neumann M147 tube + Vintech X73i
Neumann u87 + Avalon 737sp

...that would be your choice?
:) thanks

Dave...

I just found out that this ADK preamp I'm working with works without any Input Transformer inserted...

First I need to say, I'm not a signer and neither a guitar player.
This is a preamp test done with one of the most common mic the Shure SM57. Tests include the Universal Audio La610 and 710, the Focusrite ISA and the interface Focusrite Liquid Saffire 56

I'm willing to post audio samples of various Input Tranformers and Op Amps on an ADK AP-1 mic preamp, if anyone is interested.

But I don't want to go through the time and effort of doing this if it's not of interest.

Hi,
I'm looking to upgrade my drum overheads from AKG C 1000 S' to either Shure SM81's or AKG C 214's. Price and versatility are factors, but the main use will be as drum overheads. Opinionsor advice is very much appreciated. Thanks!

If anyone here can answer it, it will be Boswell.
I read over on GS that transformers (notably Studer) may need to be demagnetized. If this is true, I would expect all transformers would be suspect over time. Is this true?

These look excellent. I've never had the opportunity but hope to grab a chance to try anything in this series.

I am looking for a Spectra Sonics Console
Hoping for at least 16 channels but I am open for whatever you have to offer even if its just spare parts at this point if I have to put together something I will.
thank you so much in advance
feel free to contact at Jason@ribco.com
thanks
