Official description
Preamp circuit is switchable between two amps: RED and GREEN.

RED mode is a British classic style preamp (1073) and GREEN is an American vintage style preamp (discrete opamp). Both preamps have unique sonic textures known as a best classical sound preamps.

Carnhill transformers are responsible for matching impedance and de/symmetrization circuits. Preamp is loaded with two PADs: IN 20dB PAD and OUT 8dB PAD which allows to saturate both preamp and output transformer.

Additionally DUE-PRE has front input XLR Combo socket which can be used in both ways: as a mic input and as a instrumental input. Instrumental input is a high impedance input of which signal feeds input transformer through FET transistor. Module can draw up to 5W of power.

Specfications:


 * High quality Grayhill gain switch
 * 64dB of gain (preamps are matched with 0.5dB accuracy)
 * Canrhill in/out transformers
 * 20dB input PAD
 * 8dB output PAD (allowing saturation of both preamp and transformer)
 * Polarity Reverse switch
 * +48V phantom power
 * Front autosense XLR mic
 * Hiz Fet DI front input (the signal passes through the input transformer)
 * LED VU meter
