API 3124+ Four-Channel Microphone Preamplifier

The API 3124+ is a four-channel microphone preamplifier built around API's legendary 2520 discrete op-amp — the same circuit that defines the sound of countless classic recordings. Each of the four channels features API's signature transformer-balanced input, 48V phantom power, polarity reverse, pad, and high-pass filter, delivering the punchy, clear, and musical preamp character that engineers have relied on for decades. The 3124+ is equally at home tracking drums, acoustic instruments, brass, or any source that benefits from a fast, authoritative front end.

This example is in excellent condition and fully operational.
