|Proposition 65 Notice
|WARNING: This product can expose you to chemicals including LEAD, which is known to the State of California to cause cancer and birth defects or other reproductive harm. For more information go to www.P65Warnings.ca.gov.
|Marine Grade Protection / IPX Rating
Amplifiers are ASTM certified which defines that marine amplifiers must use conformal coated PC boards to resist corrosion from salt spray & moisture. IPX5
|Low Noise Preamplifier Circuit
Q-Stasis Pre Amplifier Stage: The highly engineered Q-Stasis pre-amplifier stage reduces incoming noise from source units dramatically improving sound quality.
2 Pair RCA Nickel-Plated: High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant.
Mono operation: Designed to power 1 subwoofer or subwoofer system.
LPF: 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 Device Technology
PWM MOSFET Power Supply: Stable power through the PC board with minimal heat generation.
Aluminum: Quickly dissapates heat to allow the amplifer to run lower impedance for longer duration.
Simpatico Coil Design: The dual coil Pulse Width Modulated power supply keeps voltage constant through the Ultra-Fi output devices.
Quick Dissconect Wires, RCA Connections: Quickly remove amplifer when you are putting machine up for the winter of as a security precaution.
Nickel-plated connections: Nickel plated corrosion resistant connections.
|LED System Protection Circuitry Diagnostics
Three-stage protection circuits: Monitor thermal, overload, DC, and speaker short protection with lighted indicators on the amplifier end panel.
