GC Audio Realism Preamp a high-end Class A 500 Series Preamp with combo connector on the front panel for Mic/Instrument input.
A great care has been taken is selecting the best components to achieve a very quiet preamp like ultra low noise transistors, very quiet Op-Amps, Coupling/decoupling link optimized for impulse response, High-end Lundahl transformer, front panel switched driven by gold contact relays.
GC Audio Realism Preamp is a complete mic / instrument preamplifier with a front panel combo input connector. Designed around a class A differential preamplifier featuring ultra low noise SSM 2212 paired transistors.
The OPA1612 are amongst the quietest Op-Amps of the market. Great care has been taken in the choice of capacitors.
Each coupling and decoupling link is optimized for an impulse response. Low values are ensured by Wima plastics and higher values by Nichicon Long Life low ESR electrolytic.
The output stage is balanced by a Lundhal LL1585 high end transformer preceded by a solid low output impedance current generator stage. The few uH generated naturally by the output coil of the transformer brings presence and a proximity feeling.
No sound passes through the front panel switches, each switch drives gold contact mechanical relays or ultra low Ron solid state relays.
The result is a very quiet preamplifier, with great realism on the top end and flawless reproduction of the sharpest transients.
