Quad Eight M3 Two Channel Microphone Preamp Custom with Vintage Components. This 2 channel Mic Preamp is custom made from the ground up using Quad Eight Components. The cards were original Quad Eight VCA Cards converted into M3 Microphone Preamps with a Jfet front end giving it a different sound than the original Quad Eight M3 Preamps, but just as Clean and Great Sounding. If I were to describe the sound it would be Motown mixed with Great Tone! These Preamps also sound Fantastic on Acoustic Guitars, Electric Guitars and Drums not to mention Vocals.Each Channel has a Transformer Bandwidth Variable Potentiometer (Input Impedance Control you can use to add tone by changing the input bandwidth), a Volume Control, 48 volt Phantom Power and Phase Switch. The output transformers are from Magnetech Preamps and the Vintage Input Transformer is a hard to find Shure Special Microphone Transformers having a Great Classic Vintage Sound. (Shure Microphone Input Transformers Recorded the original Woodstock just FYI). The LED lights above the Phantom Power Switches are powered by the 28-VDC bi-polar power supply rails so if any side of the power supply fails you will know by switching the Phantom Power on, on either channel to check to see if you have power on either rail. The bi-polar Power Supply is made of Two Power-One 28-VDC Calibrated Well Regulated 1 Amp Power Supplies that have a reputation for being reliable and long lasting (a Standard in the industry) so failing is unlikely! The rear of the Preamp has the inputs and outputs (xlr) while the line-in activated by a switch in the front is 1/4 inch unbalanced.
The 4 pin XLR Connector in the back is for the power supply that is housed in a Vintage Sencore Tubetester Metal case (with its original handle) repurposed for the Power Supply.
