Two channels.
One slot.
Zero compromise.
The KOËL Twin Pre redefines what a 500-series preamp can be.
By squeezing two FULLY DISCRETE 312 preamp circuits into a single 500-series slot, Twin Pre instantly doubles the input count of your rack — without doubling the cost or space.
Load an 8-slot rack with Twin Pres and suddenly you’re tracking 16 channels of discrete preamps — perfect for drums, live tracking, hybrid studios, and mobile rigs.
At the centre of the design is our 2520 Discrete Opamp, built from the original circuit with matched, low noise NOS transistors.
All capactiors are the highest quality, low ESR from Wima, Nichicon and Panasonic
Twice the channels. Same rack. Smarter investment.
How it works
Channel 1 uses the rear in & out on your 500 rack, Channel 2 uses the XLR in & out on the front panel.
This Doubles your available inputs without expanding your rack at a lower cost per channel than competing 312-style clones!
Classic 312 Tone — Modern Density
Each channel features its own fully discrete gain stage, carefully matched components, and transformer-balanced input and output. The result is a preamp that stays tight and punchy on drums, open and detailed on guitars, and authoritative on vocals — exactly what engineers expect from a 312-style circuit.
The difference? You get twice as much of it per slot.
