CONGRATULATIONS! Chassisink” Darlington Power Array - Soundstream’s “overbuilding” of the output section incorporates multiple outpul transislors instead of a few for faster, stronger power delivery. The transistors are sandwiched between the circuit board and the heatsink in a design called Chassisir&TM to ensure cool. efficient amplifier operation. You now own the REFERENCE Amplifier, the product of an uncompromising design and engineering philosophy.

l o0.e l e0.e 6 dB/OCTA VE PASSIVE CROSSOVER CHART REFERENCE POWER SUPPLY DESIGN The REFERENCE amplifiers employ an extremely efficient unregulated pulsewidth modulated oower SUDDIV. REFERENCE amolifiers from Soundstream are rated at 12 ;olts but &e’designed to take advantage of the additional voltage available when the vehicle is running.
l .0.. 0.0.. CROSSOVER ADJUSTMENTS 12 dB/OCTAVE PASSIVE CROSSOVER CHART In most car audio installations, there Because of their interior dimensions, midbass frequencies. If we design information in this region, the fin?. sounding. is a tendency for a “midbass boom.” most cars will resonate or ring at these the system so there is less musical response is very smooth and natural The REFERENCE300sx incorporates electronic crossover.
COHERENTSTEREOTM/ MIXED-MONO /BRIDGED MONO SETTING THE HIGH PO WERlHiGH CURRENTS WlTCH The High Power/High Current switch allows the REFERENCE amplifier to be one of two types of amps: either producing maximum power at higher impedances (perfect for satellites) or at lower impedances (usually with mukiple subwoofers). The circuit operates by selecting a sat of power supply voltage One is a higher voltage “tap” rails best suited to your particular application.
l oaoo REMOTE NRN-ON WIRING Connect POWER AND GROUND the “Remote” to the turn-on lead lrom the source unit When +12 ~011s is received, the amplifier will turn on. To ensure maximum output from your REFERENCE amplifier, use high quality, low-loss power and ground cables. The REFERENCE amplifiers will accept up to 4 gauge or 8 gauge power and ground cables. Determine from the chart below the minimum gauge power and ground wire for your application.
l I I INSTALLATION AND MOUNTING LEVEL SETTING 1. AMPLIFIER LOCATION The REFERENCE amplifiers employ highly efficient circuitry and a unique Chassisinkn” 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.
l oooa AIRBASS TM ACCESSORY OPT/ON l eoo* SPEClFlCATlONS Soundstream’s new A/FiBASSY feature can be added to the REFERENCE300sx amplifier. This feature allows wireless RF remote control level adjustment of the amplifier, while the low pass filler on the amplifier’s internal crossover is engaged. NOTE: The AKBASS” accessory is intended lo be used only wh#e the REFERENCE3OOsx amplifier is driving subwoofers.
