The GC Audio Realism 500-Series Preamp is a very quiet preamplifier with great realism in the highs and flawless reproduction of the sharpest transients.
The GC Audio Realism Preamp is a complete mic / instrument preamplifier with a front panel combo input. The design is designed around a class A differential preamplifier composed of ultra low noise SSM 2212 paired transistors. The following AOPs are also OPA1612 which are among the quietest on 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 balancing stage consists of a Lundhal high level output 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 feeling of proximity. No sound passes through the front panel switches, each switch drives gold contact mechanical relays or ultra low R-On solid state relays.
