grace design


In the early 90’s, Michael Grace began building single order custom audio products for a small, devout following of recording engineers and artists . Before long, the word had spread about these custom microphone preamplifier designs, which were said to outperform anything else that was commercially available.

Grace 101 and Earthworks QTC40 Problem

Don't know if this is the right section for this, but I'm having a noise problem recording with the QTC40 and Grace preamp. Thought maybe I could skip testing some parts of the recording chain if I describe the problem in enough detail. Using 5 mics with this project, when the Grace input began to make some noise, then the signal disappeared altogether. Simple enough, eh? However, I kept recording and the signal re-appeared with no changes on my part. I stopped, checked all connections (high quality mic cable into Grace, high quality cable from Grace into RME Multiface II).

Grace Designs Hanging Bar


I was wondering if anyone in the DC/ Baltimore area would have a grace hanging kit for the 30cm stereo bar I could borrow/rent for this coming weekend? I have tried to purchase it at several places but no one has it in stock, including the company itself. The part number is SB-HB-30/66.

I would need it from Saturday to Tuesday, 22 Sept- 25 Sept.


Grace m101 to my pre list?


I currently use a UA Solo 610, Focusrite ISA One and PreSonus Eureka in my studio.
These are all capable of different colors and all sound great.
However, all my pres are transformer type pres and apparently this adds something to the sound?

Because of this I'm tempted to get a clean/transparent sounding pre and have the possibility of picking up a secondhand Grace m101 .

From my experience of my pres I would say the Eureka in the most transparent/uncolored sounding pre of the bunch.

Grace 101 mic preamp



I am the proud new owner of a grace 101 pre and was reading up on it.

I came across this in a review by Bob Ross for Recording Magazine:

"Both the XLR and TRS jacks can feed
unbalanced sources, though Grace strongly recommends
using cables which leave pin 3 (or the ring) open to minimize

What are cables that leave pin three (Or the ring) open?
