MX Series 280w 4 Channel Full-Range Amplifier - MX280/4
PLAY ANYWHERE
With efficient NexD™ technology and a water-resistant chassis, MX amplifiers produce loads of clean power and are ideal for applications where moisture cannot be completely avoided.
- Designed for limited space applications
- Shock-resistant, water-resistant and built tough
- Efficient design for high output uses less energy
- Complete signal processing sections on board
- Exceeds international standards for salt fog and UV exposure
- 3-Year warranty
Power To Go Anywhere
Housed in a tiny cast-aluminum chassis, MX amps are rugged, water-resistant (IPX7-rated) and ready to go where conventional amplifiers wouldn’t dare.
NEXD Advantage
The highly efficient Class-D design reduces current draw and heat while generating loads of high-fidelity sound without straining small charging systems.
Complete Signal Processing
For easy setup and system flexibility, a complete set of onboard filters and signal processing features is concealed behind every MX amplifier’s water-resistant control cover.
Differential-Balanced Inputs
A versatile design accepts speaker level signals without a line-output converter — and delivers outstanding noise rejection while preventing alternator whine and other noises.
Built for the Elements
The all-aluminum, powder-coated housing with marine-grade hardware inhibits corrosion, and a water-resistant security cover protects all controls from the harshest of seasons.
