The API 312 SEPIA Module is a digitally controlled microphone preamplifier that brings the revered warmth, punch, and clarity of the classic API 312 circuit to Karno’s SEPIA L6 modular audio platform, combining true analogue tone with precise digital control. Classic Analogue Design Meets Modern Digital Workflow API has designed the 312 SEPIA Module exclusively for Karno’s SEPIA L6 rackmount system, retaining the authentic circuit topology and proprietary transformer that defined the original API 312’s sonic signature. Built, tested, and calibrated by API, the module reproduces the signature low-end authority, fast transient response, and musical saturation that have made the 312 a cornerstone of recording and live production for decades. The preamp delivers a gain range from +34.5 dB to +68 dB, or +14.5 dB to +48 dB when using the integrated PAD, ensuring compatibility with a wide range of sources. With a maximum output level of +31.5 dBu and a total harmonic distortion figure below 0.05% at +4 dBu, the 312 SEPIA maintains exceptional headroom and sonic purity. Its input impedance of 1500 ohms and transformer-balanced output (below 75 ohms) contribute to the signature API punch and depth, while the frequency response remains flat within ±0.5 dB from 20 Hz to 40 kHz. Power efficiency has also been optimised, drawing ±16V at 30 mA and +5V at 20 mA. The single-width SEPIA module form factor measures 1.6" x 2.6" x 5" deep and weighs approximately 1.2 lbs, making it compact yet robust enough for demanding studio and live environments. Total Digital Integration Through SEPIA’s digital control interface, engineers can automate gain settings, recall presets, and adjust parameters in real time, allowing the 312 SEPIA Module to integrate seamlessly into hybrid workflows. This fusion of analogue integrity and digital precision gives producers and live engineers the flexibility to combine the character of vintage hardware with the efficiency of modern recall and automation systems. Why Choose the API 312 SEPIA Module Experience the authentic analogue tone of the legendary API 312 with modern digital control Achieve pristine signal integrity and high headroom in both recording and live environments Seamlessly automate and recall settings through Karno’s SEPIA digital system Benefit from API’s precision engineering and transformer design Compact, rugged, and power-efficient for both touring and studio integration Strictly limited edition for discerning professionals seeking exclusivity and heritage
