3122V 2-Channel Mic Preamp
Microphone Preamplifier
From API:
The new 3122V provides 2 channels of API’s signature analog sound and features the same legendary circuit design found in the 3124V and 3124MV, as well as the 312, 512V, and 512c mic preamps. In addition to the familiar combination of 2520 Op Amps and proprietary output transformers that give all API mic preamps that punch and massive headroom, the 3122V also includes front and rear panel XLR and 1/4″ inputs (conveniently selectable on the faceplate), a fixed-frequency HP filter, GAIN and the popular Variable Output Level control, as well as 48V, POL, and PAD. Rounding out the expansive feature set are the 3:1 Output Transformer Tap and 2 stunning analog VU meters with a separate peak LED.
