All discrete, transformer balanced input/output design. Hi-z 1/4" input on front panel. Polarity, +48v phantom power, -20 dB pad, mic/hi-z switch all available on front panel. 7 segment LED VU level display. Tons of gain. Great on everything, except when the source sounds bad. Not a flattering preamp. GIGO.
Classic Audio Products of Illinois clone of API 312 design with output fader.
4 channel mic pre/line amp with 1/4" hi-z inputs. Based on Trident A-Range design. Excellent on drums.
API 312-style preamp custom designed for our MCI JH-636 mixing board by Nikhil Ranade with the help of Eliot Curtis. The circuit design is dead simple and utilizes a Jensen JE-115K-E microphone input transformer followed by a 2520-style discrete op amp. The output is transformerless. Sonically very similar to the API 312 with less gain range. Distorts nicely when driven hard. We have 12 of these installed in our console.
From a decommissioned broadcast console. Often touted as "the Canadian Neve". Whatever. Large Hammond mic input transformer. Transformerless output. Great sound especially on electric guitar.
