API 512V 500 Series Discrete Microphone Preamp

Ideal as a front end in studios for recording a wide range of input sources, the API Audio 512v is a mic/line/instrument preamp module designed for 500-series racks. Sporting up to 65 dB of mic gain (45 dB of instrument gain) and a front-panel XLR-1/4" combo input jack, as well as rear panel mic input support, this module provides low-noise input for any signal.

Output level control is variable, allowing for smooth and fine adjustment. There is 48V phantom power available for condensers and other active mics. When the 3:1 output transformer tap is engaged, the output gain ratio is reduced to 1:1. When taking in excessively hot signals, such as those already boosted by a preamp, a -20 dB pad is available. You can also engage a polarity flip switch. An LED VU meter lets you keep an eye on your signal levels. With discrete circuitry and the signature 2520 op-amp, this preamp module offers an excellent front-end sound, with warmth and reliability.
