BAE 312A Single-Channel Mic Preamp/DI without PSU

Single-channel microphone preamp with BAE 2015 opamps and Jensen input and output transformers - fast and punchy sound - PSU not included

Product Description

The BAE 312A is a world-class preamp that combines a capacitor-free circuit with high-quality Jensen transformers and BAE’s proprietary 2015 op-amp for a fast, punchy sound. Perfect for recording drums and fattening up bass DI tracks, the BAE 312A delivers a thick, rich tone with crisp, clear transients.


The BAE 312A preamp is hand-wired using high-quality components to ensure world-class tone. Hearty Jensen transformers at the input and output stages are perfect for adding warmth to any instrument. The capacitor-free signal path easily allows transients to pass through for punchy, percussive recordings. BAE’s custom built discrete 2015 op-amp provides a clean, transparent sound that takes well to EQ and dynamics processing.


The BAE 312A features an intuitive design with easy-to-use controls. A large, rugged dial controls gain settings, offering an impressive 66 dB of gain. The mic/instrument switch allows you to toggle between the microphone and high-impedance line level input on the front panel for recording direct instrument signals. The pad button reduces input gain for recording particularly loud instruments like heavy-hitting drummers or roaring guitar amps. The phase reversal button inverts the phase of a signal—perfect for recording snare bottom mics! The 48 V button provides phantom power for condenser microphones.

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.
