Soundstream Technologies REF1.500, REF4.400, REF2.370 manual Psu

PSU

•Pulse Width Modulated

•Large TO218 MOSFET Transistors

•High Volume, Low ESR Capacitance Banks Compensate Power Supply Ripple Currents

•Extra Low Current Drive Stage Increases Efficiency & Sound Clarity

•Individually Regulated Preamp/Crossover Power Supplies Ensure Signal Purity

•Separated Capacitor Charging/Discharging Current Paths Prevent Rail Switching Spikes & Ground Traces from En- tering Signal Stages Resulting in Distortion

Mono-block Models:

•True Class G Circuitry and Regulated MOSFET Power Supply. This allows the Subwoofer Amplifiers to Yield the Same POWER at 1-2 ohms, and Regardless of Operating DC Voltage. (You can use almost any amount of woofers, and of any impedance, and wire it to the amplifier safely! See the options in the back of the manual…)
