M72 Dual Channel Discrete Preamplifier

Congratulations on your purchase of your new Vintage Audio M72 Dual Channel

all discrete Microphone Preamplifier

The M72 is based on the British classic 1272 (BA283) preamp and is a faithful

reproduction using original Carnhill/St Ives input and output transformers coupled

an all discrete design.

We put tremendous effort into all of our preamps and compressors to make your
music more enjoyable and your sessions less droll. Each unit is hand built to our

specifications and is constructed of nothing but the highest quality parts. As with

all of our preamps the M72 uses remote relay switching which shortens the signal

path and lowers noise making the preamps performance even better. Excellent

filtering is also provided to lower ripple and thus lower the noise floor even further

making them extremely quiet in terms of self noise.

Our M72 model comes with a full one year warranty and is built to the highest

standard using the highest quality components.

Caution!

As with all professional equipment, please be sure to read all necessary

literature prior to hooking devices up and powering them on. All units are

set for voltage based on the original sale destination. Please consult the tag

below the AC inlet if you purchased a unit “used” or second hand to make

sure it is set for the right voltage before applying AC voltage.
