John Hardy Co. M-1 Mic Preamp Single Channel

Professional mic pre utilizing premium Jensen components
MFR# M-1 Mic Preamp Single Channel

Product Description

The M-1 mic preamps are among the finest mic preamps in the world. They provide the accuracy and transparency that is missing in other mic preamps. No matter what your application, they will provide superior sound quality. The world's best input transformer (Jensen JT-16-B), best op-amp (990 discrete op-amp) and the elimination of all capacitors from the signal path combine to provide the highest performance.

The M-1 has a 19" wide mainframe rack-mount chassis (1.75"H x 19"W x 8"D) and can be ordered with 1 to 4 channels. There are two meter options and the best Jensen output transformer (JT-11-BMQ) is also available as an option. Additional channels and options can be easily added later up to the total capacity of the mainframe.

The M-1 was introduced in 1987 and while sonically identical to the M-2 there are a few control differences. The M-1 has a two-section gain-pot providing continuously variable adjustment in two overlapping ranges that are selected by the "High Gain" switch. (The M-2 has a 16 position gain-switch with 1% metal-film resistors providing accurate and repeatable gain settings and since the "High Gain" switch isn't necessary it's available with either a 20 ohm mic switch OR a 20dB pad switch.)

Highlights:

  • JT-16-B Input Transformer
  • 990 discrete op-amp - faster, quieter, more powerful and better sounding than typical monolithic op-amps
  • Elimination of all coupling capacitors from the signal path - results in less degradation of the audio signal


Features:

  • Dual range gain control and 'high gain' switch - provides great feel and resolution for easy and accurate adjustments
  • Polarity reverse switch
  • Phantom power switch
  • All front panel switches are LED illuminated
  • Gold plated XLR connectors
  • Ground lift switch on each channel - helpful for eliminating ground loops
  • Toroidal power transformer with additional shielding - eliminates hum problems so no external power supply is needed
  • Universal power supply - internal switch provides six primary voltage choices to accommodate use anywhere in the world
  • Chassis ground isolation switch - helpful for eliminating ground loops

Options:

  • VU-1 - Very accurate and informative 20 segment LED meter card with separate peak LED for monitoring preamp output
  • PK-1 - Peak LED metering only (not required if VU-1 is installed)
  • JT-11 - BMQ output transformer
  • Pin 2 Or pin 3 high - can be ordered either way and internal jumpers make changes in the field easy

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.
