* Marine Grade Protection: YES
Amplifiers are ABYC & 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 (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: Included
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
