Soundstream Technologies 300SX manual Design Features, Congratulations

CONGRATULATIONS!

You now own the REFERENCE Amplifier, the product of an uncompromising design and engineering philosophy. Your SoLndstream REFERENCE amplifier will outperform any other amplifier in the world.

To madmize the pedorrnance of your system, we recommend that you thoroughly acquaint yourself with its capabilities and features. Please retain this manual and your sales and installation receipts for future reference.

Soundstream amplifiers are the result 01 American craftsmanship and the highest quality control standards, and when properly installed will provide you with many years of listening pleasure. Should your amplifier ever need service or replacement due to theft, please record the following information, which will help protect your investment.

DESIGN FEATURES

. Uncompromising Design and Construction - including mil-spec glass epoxy circuit boards and high current custom gold-plated solid brass connections that will accept up to 4 gauge power/ground wire.

. Hlgh PowerRligh Current CapabIlity - Soundstream’s exclusive circuit which permits customization of your amplifier to its particular application-high current, low impedance loads (multiple subwoofers, less than 2 ohms mono) or High Paver, higher impedance loads (2 ohms mono and up).

. Coherent StereoTYIMlxed Mono - selection for either “pure” stereo operation or mixed mono for simultaneous stereo and mono.

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.

PowerGrid Power Supply Design - All power supply components are located near one another. connected by thick. wide PCB traces. which ensures rapid, high current delivery. The entire power supply is isolated on one side of the circuit board while the audio stage is located opposite if, guaranteeing minimal noise

Ultra-Low ESR Capacitance Bank-Multiple small input power capacitors are used to provide a lower ESR (Equivalent Series Resistance), which means more power in and auf faster.

Smart Thermal Rollback - Most amplifiers shut off when they get too hot. In the unlikely event the REFERENCE300sx amplifier reaches 85” C, it will gradually roil back its average power (without affecting the dynamics). Once the amplifier has cooled off, it returns to full power oulput. If overheating should continue, a second thermal sensing protection circuit will shut off the amplifier if the heatsink reaches 95” C.

Unregulated Power Supply 4 ohm power ratings are measured at 12 volts, meaning substantially greater oulpui in the real world when the vehicle is funning, where voltages range from 13.2 to 14.4 volts.

•Fautl Monitor LED - on the top panel notifies you of blown power supply fuses.

•l/2 ohm Drlve Abiiliy -The REFERENCE amplifiers are designed to drive virtually any load-all the way down to l/2 ohm stereo (1 ohm mono).

•Dual Discrete Class A Drive Stages . Over six times the drive current of most amps, which maintains perfomlance into low impedance loads.

•Drive DelayTH Muted Turn-oWofl Circuit . A unique circuit which completely eliminates any amplifier-related turn-on/off noises.

•Flexible hput Sensitivity - accepts voltages from 200 mV to 5.0 V, penitling maximum output from the amplifier with virtually any source.

•Differential Balanced input Design - for added immunity to noise caused ,by component and vehicle electrical system interaction when using \Inbalanced RCA inputs.
