The M-2 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-2 has a 16 position gain-switch with 1% metal-film resistors providing accurate and repeatable gain settings from 15dB to 60dB in 3dB steps.
The M-2 has a 19" wide mainframe rack-mount chassis (1.75"H x 19"W x 8"D) and can be ordered with one to four channels. There are two meter options and the John Hardy 11C line output transformer is also available as an option. Additional channels and options can be easily added later up to the total capacity of the mainframe. Also when you order your M-2 you can specify if it will have a 20 ohm mic switch or a 20dB pad switch.
Sonically, the M1 and M2 are identical.
The 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 )
- John Hardy 11C line output transformer
- Pin 2 Or Pin 3 high - can be ordered either way and internal jumpers make changes in the field easy
John Hardy Co. M2-2 Dual Channel Mic Preamp
