Mercury Grand Pre – No Longer Available

Solid state, discrete, dual-channel mic pre
MFR# Grand Pre

Product Description

The Mercury Grand Pre is more open and musical than other similar amplifiers of the same type and/or topology. The Mercury Grand Pre is not another "Twelve Seventy Two" clone. Instead, the Grand Pre is the new, alternative British classic!

The Mercury Grand Pre is available in both two-channel and one-channel (GP1) versions.


  • Input Gain Control 0-60dB in 12dB steps (-0, -12, -24, -36, -48 and -60dB) that works in combination with the Fine Gain Control (trim) that is +/- 8dB
  • Phantom (48V), Phase Reverse (Polarity)
  • Output Control (Fader) and a newly designed FET Direct Input per channel
  • FET Direct Input - very full sounding - more mid range and low end presence then most D.I.s as well as an open and airy top end and overall punchiness you would expect from a Class A discrete amplifier
  • The inputs and outputs of the Grand Pre are balanced using the original Sowter transformers
  • The Mercury Grand Pre's internally mounted power supply uses a toroidal transformer and is regulated for super low noise and stable performance
  • Each amplifier channel is locally regulated to eliminate cross talk between channels
  • Single channel back panel 

The Mercury Grand Pre is 19" rack mountable and housed in a beautiful, gray hammer finish, steel chassis. The aluminum front (control) panel has a custom powder coated finish giving the Mercury Grand Pre the look and feel of the era it comes from with a twist. The Grand Pre has the "look" of a classic hot rod with it's black, red and chrome color scheme.

I would like to thank VK for the wonderful sales assistance, service and prices. This was my first purchase with you and it won't be my last. I only wish I'd discovered you years ago!

I had two Grammy wins this year - Ray LaMontagne & Carolina Chocolate Drops. Both made with help from Vintage King!

In almost 20 years in Pro audio buying, never did I receive a unit so well packed and exactly as described. Works flawlessly. The whole process has been so smooth. I will never hesitate to do business with you guys in the future and will recommend you to everyone I know.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
