Overview Hifonics THOR compact Five Channel, 600 watt Powersports amplifier with on-board equalization and simple installation with quick release connectors. Bass remote included. Features & Benefits MARINE GRADE PROTECTION: YES Amplifiers are ASTM certified which defines that marine amplifiers must use conformal coated PC boards to resist corrosion from salt spray & moisture. PRE-AMP CIRCUITRY: Low Noise Pre-Amplifier Stage Special preamplifier reduces incoming noise from source units dramatically improving sound quality INPUTS: 2 Pair, RCA (Front/Rear) 1 Pair, RCA (Subwoofer) Nickel-Plated High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant OPERATION MODE: Four channel and with dedicated subwoofer channel Unique 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 D Highly efficient circuit topology which helps the amplifer develop a lot of power in a very small heatsink. OUTPUT DEVICES TECHNOLOGY: PWM MOSFET Power Supply Stable 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 Design The dual coil Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices BASS REMOTE INLUDED: YES Wired Bass Remote allows adjustments to bass frequencies to be made from the control mounted anywhere in the vehicle. OUTPUT CONNECTIONS: Quick Dissconect Wires, RCA Connections Quickly remove amplifer when you are putting machine up for the winter of as a security precaution CONNECTIONS TYPE: Nickel plated corrosion resistant connections DIAGNOSTICS: Three-stage protection circuits Monitor thermal, overload, DC, and speaker short protection with lighted indicators on the amplifier end panel MARINIZED / WATERPROOF: YES Water resistant for durability in any environment
