Price is for one unit. I am selling both if you want to make an offer for the pair. Both are in excellent cosmetic shape and work perfectly.

API 512c Mic Preamp
Classic API 512c 500-series microphone preamp. The 512c delivers the familiar API sound: fast, punchy, forward, and extremely useful on drums, guitars, bass, vocals, and virtually any source where you want clarity and transient impact.
Features the API 2520 op-amp and output transformer, with up to 65 dB of gain, 48V phantom power, polarity reverse, and a -20 dB pad. The simple circuit and generous headroom make it a studio staple for a reason.
