Pre-Amp Circuitry: Q-Stasis Pre Amplifier StageThe highly engineered Q-Stasis pre-amplifier stage reduces incoming noise from source units dramatically improving sound quality Inputs: 2 Pair, RCA Front/Rear1 Pair RCA Subwoofer Nickel-PlatedHigh temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant Operation Mode: Four channel and with dedicated subwoofer channelUnique design allows this amplifier to power full range speakers with a dedicated channel for a subwoofer. Crossover / Signal Shaping: Switched FULL / LPF / HPF Complete control of amplifier signal, essential when using two or more amplifiers Class / Topology: Full Range Class DHighly efficient circuit topology which helps the amplifer develop a lot of power in a very small heatsink. Output Devices Technology: PWM MOSFET Power SupplyStable power through the PC board with minimal heat generation Heat Sink: Aluminum Quickly dissapates heat to allow the amplifer to run lower impedance for longer duration Power Supply: Simpatico Coil DesignThe dual coil Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices Bass Remote: IncludedWired Bass Remote allows adjustments to bass frequencies to be made from the control mounted anywhere in the vehicle. Output Connections: Quick Dissconect Wires, RCA ConnectionsQuickly remove amplifer when y
