Mic preamp and DI in a 500 Series format.

BAE Audio is known for manufacturing high-end microphone preamps and EQs that are faithful to original vintage designs from the 70s and earlier. BAE prides itself on using high-end transformers for their products, and everything is kept as close to the vintage philosophy as possible. Not only does BAE choose the highest quality components, they also insist that everything is hand-wired/soldered using discreet electronics and not economized on a circuit board.

The 312B Signature Series carries the same excellent dynamic range, frequency response and noise performance the BAE 312 series is known for, but with a newly introduced and modified gain structure which utilizes a lower gain Jensen input transformer, designed to compliment louder sources before needing to implement the pad.

The 312A's higher gain structure occasionally required the pad to be used frequently with louder sources, such as a hot microphone on drums. The 312B uses an alternative Jensen transformer putting it at 7dB's of lower gain to accommodate louder sources without losing the dynamic characteristics of the 312A. This allows engineers the option of owning the 312A as a pre-amp geared toward higher gain and the 312B for toward lower gain.

The 312B, just like the 312A, features the Avedis 1122 Discrete Op-Amp and input and output Jensen transformers which use direct-coupled circuitry with no capacitors in the signal path. The input impedance of the 312B is designed to remain consistent, even after the pad is engaged, providing a steady load to the microphone. The characteristics of the 312B offer excellent dynamic range, frequency response, high headroom, and excellent noise performance for a punchy sound which works well with many microphones.

  • Made using Avedis 1122 opamps
  • Supplied with Jensen input and output transformers
  • Remote power supply with four-foot cable capable of four times the current needed by the preamps for optimum sound quality
  • Switches have gold contacts for long life
  • XLR connectors on the back for mic input and output and phone jack in front for direct input
  • High impedance direct input for guitar and synthesizer
  • Separate front panel switches for phantom power

As close to the original as you can get, order yours today!
