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: Q-Stasis Pre Amplifier Stage The highly engineered Q-Stasis pre-amplifier stage reduces incoming noise from source units dramatically improving sound quality
INPUTS: 2 Pair, RCA Nickel-Plated High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant
OPERATION MODE: Four channel operation Flexible installation allows this amplifier to run in four channel or bridged mono mode.
CROSSOVER / SIGNAL SHAPING: Switched OFF / HP 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
OUTPUT CONNECTIONS: Quick Dissconect Wires, RCA Connections Quickly remove amplifer when you are putting machine up for the winter of as a security precaution
