DEStGN FEATURES 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 ChassisinkTM Darlington Power Array - Soundstream’s “overbuilding” of the 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, efficient amplifier operation.

Page 10: Lse.q Theory And Use
LSE.Q THEORY AND USE LSE.Q is a unique subwoofer control circuit included with the REFERENCE SOUNDSTREAM Class A 6.0 amplifier. It is capable of subsonic energy removing The circuit program material. consists of two controls. One adjusts the frequency of operation and the other adjusts the range of boost. - Page 11 This serves the purpose of removing the “subsonic” bass energy. Soundstream’s LSE.Q contains the same type of circuit with the added benefit of infinite adjustability. Our “Q” and “Hz” control can provide virtually any combination of boost and cut to suit your designs.

i INSTALLATION STEP 4 t 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. -
Page 17: Level Setting
q INSTALLATION STEP 5 t 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. -
