API 512V Mic/Line/Instrument Preamp - 500 Series
The API 512V is a world-class mic/line/instrument preamp renowned for its pristine sound quality, low noise performance, and instantly recognisable API tone. Designed in the scalable 500 Series format, the 512V delivers professional-grade preamplification for any source — from vocals and acoustic instruments to line-level sources and electric guitars — all in a compact, affordable package.
At the heart of the 512V lies API’s legendary 2520 discrete op amp and fully transformer-balanced signal path, offering up to 65 dB of gain for microphones and 45 dB of gain for line or instrument inputs. The front panel features a convenient combo-style XLR + 1/4″ input, while additional mic input access is available on the rear panel, ensuring seamless integration into any studio or stage setup.
One of the standout features of the 512V is its Variable Output Level Control, allowing engineers to drive the preamp harder for added saturation while maintaining precise output levels. Additionally, the 3:1 Output Transformer Tap offers expanded tonal versatility, making the 512V an exceptional front-end for any recording chain.
Rounding out its professional feature set are switchable 48V phantom power, a 20 dB pad (applicable to all input types), a LED VU meter for visual gain level monitoring, and API's rugged build quality backed by their exclusive 5-Year Warranty.
