4 INSTALLATION STEP 1 t DESIGN FEATURES Handcrafted in the U.S.A. with mil-spec glass epoxy circuit boards, low-loss connections, gold plated input connectors, and metal film resistors. Darlington High Current Discrete Output Topology - Soundstream’s “overbuilding” of the output section incorporates Darlington output devices sandwiched between the circuit board and the heat sink in a design called ChassisinkTM to ensure cool, efficient amplifier operation.
4 In most car audio installations, there is a tendency for a “midbass boom.” Because of their interior dimensions, most cars will resonate or ring at these midbass frequencies. If we design the system so there is less musical information in this region, the final response is very smooth and natural sounding. I The SA-120, 244, & 24s incorporate a staggered electronic crossover. The high and low pass portions of the crossover can be set independent of one another. vet pass _I Below is a chart of S.I.P.
4 INSTALLATION STEP 3 t {Continued from page 14) WIRING INTERNAL POWER AND GROUND To assure maximum output from your amplifier, use high quality, low-loss power and ground cables. Soundstream SA amplifiers incorporate gold-plated barrier strips for maximum power transfer and protection from corrosion. The screw terminals back out for use with spade & ring terminals, as well as bare wire. Determine from the chart below the minimum gauge power and ground wire for your application.

AMPLIFIER LOCATION The SA amplifiers employ highly efficient circuitry and a unique Chassisinkm 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.

SERVICE PROTECTION CIRCUITRY Your SA amplifier is protected against both overheating and short circuits by means of the following circuits: l Main power supply fuses. l A fail-safe thermal protection circuit activating at 95°C. l Self-resetting circuit breakers to protect against short circuits. NOTE: If you experience blown main power supply fuses, DO NOT increase values beyond the original values! Doing so will void your warranty and may damage your amplifier.
