DESlGN 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.
Mixed Mono Capable so you can simultaneously drive a stereo and mono load (satellites and subwoofer).
2 Ohm Drive Ability - The Granite amplifiers are designed to drive loads all the way down to 2 Ohms stereo and 4 Ohms bridged.
Built-in Staggered Asymmetrical Crossovers (Granite 120.4, Granite 180.6) - Built-in electronic crossovers are designed to compensate for the acoustics of the automobile environment. A high pass crossover (at 150 Hz @ 12 dB/octave) and low pass crossover (at 75 Hz @ 12 dB/octave) allow you to drive a complete subwoofer and satellite system without the use of passive crossovers.
l Internal Signal Routing (Granite 120.4, Granite 180.6) - Permits one pair of signal cables to drive all 4 channels (Granite 120.4) or two pairs of signal cables to drive all 6 channels (Granite 180.6).
l Drive Delay Muted Tunum/off Circuit - a unique circuit which completely eliminates any amplifier-related turn-on/off noises.
l Flexible Input Sensitivity - accepts input voltages from 100 mV to 2.5 V, which permits maximum output from amplifier with virtually any source unit.
*?Balancing Act? Input Topology for added immunity to ground loops caused by component and vehicle electrical system interaction
