IGS Audio Pure Tube Channel Microphone Preamp

Single-channel full-tube mic pream featuring a Carnhill input transformer, two military-grade tubes (6N2P-EW and 6N1P-EW), and two Mundorf capacitors to get the best classic tube sound and low non-harmonic distortion
MFR# Pure Tube Channel PTC

Product Description

The IGS Audio Pure Tube Channel Microphone Preamp features a classic pure tube signal path built with a minimalistic approach and minimum passive parts including an input Carnhill transformer, two military-grade tubes: 6N2P-EW and 6N1P-EW which work in class A and an Edcor output transformer. The signal path includes only two Mundorf capacitors to get the best classic tube sound and as low non-harmonic distortion as possible.

High impedance instrument input

A specially designed high impedance instrument input is added for direct recording of guitar, bass or sound modules. The signal is fed directly to the tube grid for classic sound performance. High Z input is also suitable for recording of clean guitars for later use with amp modeling software in your DAW. In this case, your recordings can benefit from a low noise, proper impedance matching and added nice tube coloration for the high-quality final result.

Balanced transformer isolated input and output

The best microphone preamp must have both input and output transformers. They isolate galvanically the preamp from other audio devices, and give the best isolated balanced signals with lowest CMMR and increase the sound quality adding pretty sweet musically harmonics to your recordings. On the backside, PTC is equipped with 2 XLRs and easy to access tube sockets.

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.

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.

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.
