Unleash the full potential of your recordings with the BAE Audio API 312 preamp, a paragon of pristine sound clarity in the realm of studio recording gear. Renowned for its Avedis 1122 op-amps and robust Jensen input and output transformers, this preamp ensures that your audio remains uncolored and true to source. Ideal for capturing the dynamic nuances of drums and percussion, the API 312's capacitor-free audio path allows transients to pass effortlessly, delivering a crisp and punchy sound that resonates with authenticity.

The intuitive top panel features user-friendly controls like a pad, polarity reverse, 48V phantom power, and a gain pot, letting you focus on the creative process without getting bogged down by complexity. Whether you're recording vocals, guitars, or any other instrument, the API 312 provides the warmth and punch that make your sounds come alive.

With a frequency response of 5Hz-75kHz, this preamp captures every detail with precision, offering up to 66dB of gain to handle even the most challenging lower-output mics.

Used on Icky Thump, as stated by recording and mixing engineer Joe Chiccarelli in this October 2007 Sound on Sound interview.

“The Trident at Blackbird Studio D was used for monitoring, and also some guitar microphones, plus most of the room microphones. Some room mics went through an API 512, and a few through a crazy old RCA OP6 tube preamp. Most of the other close mics went through various Neve 1073, Brent Averill API 312 and Chandler TG2 preamps. Jack loves the sound of ribbon microphones, so we used a lot of them, on guitar amps, vocals, and as room mics: Coles 4038, Royer 121, AEA R84. I would have six to 10 room mics up, and would chose a stereo pair from them."
