Product information Eton MA4 - 4-channel digital amplifier

ETON MA 4 - compact 4-channel amplifier, powerful digital mini amplifier for cars and mobile homes, Class D amp with 4 x 105 W

The new MA amplifiers are the successors to the award-winning, powerful MINI and POWER amplifier series.
The 4-channel model MA 4 is a completely new development that focuses on maximum features, top high-end sound and high output power - HIGH GRADE CAR AUDIO, very compactly designed for best installation.
Multilayer boards, high-quality electronic components and first-class workmanship form the basis for the advanced Class D amplifier technology used, which is highly efficient and ensures top sound at all levels - fine resolution, distortion-free, with sensationally low distortion and full control.
The MA 4 offers the finest electronics in an elegant, one-piece die-cast aluminum housing with a matt, anodized gunmetal finish. The top plate with the ETON logo is removable and can be rotated 180ø to ensure flexible installation and optimal optical integration.
There are numerous setting options hidden under the top plate: 12 dB/oct. High and low pass filters, control of high-level input voltage and high-level input resistance (EPS load) as well as gain.
The MA 4 impresses with numerous other design features, such as the adjustment tool for the filter functions and gain integrated in the heat sink.
There is also a status LED light bar, which makes it easier to adjust the controls with its indirect light. Removable plug connections for power and audio signals and variable mounting feet round off the features.
The MA power amplifiers are stackable and enable hidden installation thanks to additional mounting points and blind holes.
The MA 4 is engineered in Germany.
