Features of NA2-400.2:
- MB QUART NA2 400.2 400w 2-Channel Amplifier Amp For Polaris ATV UTV RZR CART
-
- 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: 1 Pair, RCA Nickel-Plated – High temperature impact resistant with hex screw terminals that allow for secure connections and is erosion resistant
-
- Operation Mode: Two channel operation – Flexible installation allows this amplifier to run in two channel or bridged mono mode.
-
- 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
-
- Output Connections: Quick Dissconect Wires, RCA Connections – Quickly remove amplifer when you are putting machine up for the winter of as a security precaution
