    MONO I STEREO I MIXED MONO Pure Class A” Output Topology for the utmost in musicality and definitive power output. Soundstream’s uniqe design allows the Class A amplifiers to deliver uncomparable sonics or, when operated at lower impedances, to provide phenomenal amounts of power.
  • Page 5 output section incorporates multiple output transistors instead of a few for faster, stronger power delivery. The transistors are sandwiched between the circuit board and the heatsink in a design called Chassisink” to ensure cool, near one another, connected by thick, wide PCB traces, which ensures rapid, high current delivery.
  • Page 6: Reference Power Supply Design

    The REFERENCE Class A amplifiers employ an extremely efficient unregulated pulse-width modulated power supply. REFERENCE Class A amplifiers from Soundstream are rated at 12 volts but are designed to take advantage of the additional voltage available when the vehicle is running. The two major...

  • Page 16: Installation And Mounting

    INSTALLATION AND MOUNTING 1. AMPLIFIER LOCATION The REFERENCE Class A amplifiers employ highly efficient circuitry and a unique ChassisinkTM design to maintain lower operating temperatures. Additional cooling may be required if the amplifier is located in a tightly confined area or when driving especially low impedance loads at extremely high levels. When mounting the amplifier, it should be securely mounted to either a panel in the vehicle or an amp board or rack that is securely mounted to the vehicle.
  • Page 17: Level Setting

    LEVEL SETTING The input levels are adjusted by means of the input level controls located on the front of the amplifier. This is a unique dual-stage circuit that adjusts both level and gain. This topology maintains better Signal to Noise ratios even when using sources with minimal output.
