Mercury Grand Pre

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.

The speed of delivery exceeded my expectations! I was VERY pleased that my shipment arrived in time for a scheduled vocal tracking session. The packing insured that my order arrived safely. And the sales staff responded quickly to questions regarding the product.

You guys have excellent customer service and I am excited about the next upgrade I complete on my fifth recording facility. I've been in the studio business for forty plus years. The salesman I worked with at Vintage King was the best of the best. You all rock!

My experience with Vintage King was excellent. The order was here fast considering it was out of stock. The sales person had SKB send it to me directly and I couldn't have been more pleased.
Michael D.
From the minute I placed my order I was kept well-informed through each step in your process. Even though I was buying a comparatively modest piece of gear, your attention to detail made me feel like I was purchasing a six-figure mixing desk.
Thomas W.
I am a new customer of yours. You guys provided me the absolute best deals in ordering all the equipment to power my brand new recording studio. Your customer service is amazing and i will always deal with you from here on out.
