Engström MONICA Mk3 Pre-Amplifier
MONICA Mk3 Pre-Amplifier
Named after one of Sweden’s favorite singers, MONICA is a fully balanced and perfectly matching pre-amplifier for LARS, ERIC and even ARNE for an extra boost or desired bi-amping. Inside its simple design are best-in-class components and a lifetime of engineering experience.
With six inputs for each channel (three balanced XLR and three unbalanced RCA connectors) and four outputs for each channel (two balanced XLR and two un-balanced RCA) MONICA works in harmony with your sound system.
MONICA features a fully balanced line stage and no negative feedback is used in the creation of its pure, distinct sound.
The core of the circuit is a unique two-totem-pole design in a balanced configuration, with four triode elements in each channel. Using a clever layout to separate the pure signal processing from the dirty components.
