The BAE 312A is a dual channel mic preamp made using Avedis 1122 opamps. They are excellent for drums and percussion. The sound is in your face.
The 312A is available as a 500 series module or a single or dual channel 19" rackmount.
Because there are no capacitors in the audio path, the 312A is super fast and punchy, allowing transients to pass easily, making them a favourite for drummers.
Made with the highest quality parts including Jensen input and output transformers and the Avedis 1122 opamp. The 312A also includes a high impedance DI for instruments.
