MB Quart NA2-320.4 Nautic 4 Channel 320 Watt Powersports Amplifier

NA2-320.4, four Channel, 320 watt Powersports amplifier with on-board equalization and simple installation with quick release connectors.

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.

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.

RCA 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 Type

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 Device 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.

Connection Type

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.
