Walker's 312 originally served as the mic input amp for all of the early API consoles in the 1970s. While Brent Averill and other engineers would later repurpose original 312 cards or recreate them in rack enclosures, this 50th anniversary model marks the first time that API has placed the 312 in a 500 Series module.
It includes a vintage-style analog VU meter as well as API's 2516 Input Transformer. Only 150 anniversary 312 modules will be built.
The main features, according to API, are:
- API's Classic 312 Microphone Preamp in a 500 Series module
- Reproduction of the Original 312 PCB Design
- Mic Preamp with 65 dB of gain
- Proprietary AP2516 Input Transformer
- 20 dB pad switch
- Switchable 48V phantom power
- Vintage Style Analog VU Meter
- Peak LED
- Limited Production with 50th Anniversary Faceplate
- Individually Serialized (1-150)
