API’s new 512v mic preamp isn’t so different from the 512c — it’s got the same transformers and 2520 op amp — but it includes a variable output level control to provide built-in signal attenuation when working with DAWs or other input level-sensitive devices.
The 512v gives you 65dB of mic gain, 45dB gain as a line/instrument preamp, and a 20dB pad switch can be applied to either input circuit. The 512v also features a 3:1 output transformer tap switch that produces a lower output level letting you drive the transformer harder for some saturation. Also included are front and back panel mic input access, front panel combo-style XLR plus quarter-inch line/instrument input, an LED VU meter for gain level indication, and 48V phantom power switch.
The 512v has an MSRP of $1500 and comes with a five-year warranty.
