Soundstream REF4.920 920W RMS 4-Channel Class A/B Reference Series Model No. REF4.920 Part No. REF4920
General:
Sequenced Delays Eliminate Residual Power-Up/Power-Down Pops
Differential RCA Inputs Isolate 12V/Audio to Ground, Eliminating Ground Loops and Noise
Full Signal Path Low Noise/Distortion Circuitry Topology
Optimal Component Layout for Minimal Distortion Induction & Signal Separation
Triple Darlington Audio Output Stages
Differential Drives Divide Pre-Amp & Power-Amp Stages, Eliminating Ground Looping
Full Differential Feedback Surrounding Power-Amp Stages directly from Speaker Terminals resulting in Uncolored Sound Reproduction and Elimination of Ground Loops
Output Stage Bias Individually Sequenced, Optimizing Sound Quality
Stout 2 Oz. Copper Traces Effortlessly Transfer High Volume Internal Current
Close Tolerance Signal Path Components - 1% Resistors & 5% Capacitors
Final PCB Layout Designs are culmination of examination and fine tuning of all circuit elements to work in harmony as a whole
