The 4-channel amplifier EA-MT4 from Emphaser offers an impressive combination of power and compactness. With an output of up to 4 x 100 watts RMS at 4 ohms and 2 x 320 watts RMS in bridged mode, the EA-MT4 delivers powerful sound with minimal distortion. The amplifier stands out with its enormous frequency range from 10 Hz to 55 kHz and high channel separation for precise spatial imaging. Equipped with variable high-pass and low-pass filters, RCA and high-level inputs, as well as an auto turn-on function, the EA-MT4 is versatile and easy to use in various car audio systems. The compact design with a massive die-cast aluminum heat sink ensures efficient heat dissipation and allows installation in tight spaces.

The Sound

The 4-channel amplifier EA-MT4 from the Monolith series by Emphaser not only delivers concentrated power, but also outstanding dynamics and exceptional signal fidelity. The very linear frequency response from 10 Hz – 55 kHz and the low distortion values give the music signal the opportunity to fully unfold and leave out no detail. The high channel separation > 60 dB ensures wonderful spatiality and precise placement of the musical performance.

The Performance

Measuring only 212 x 35 x 110 mm, the very compact EA-MT4 delivers high power in a very small space. The exceptional aluminum die-cast heatsink design allows significantly smaller dimensions while maintaining excellent temperature management. The optimized Class-D amplifier circuit, combined with the massive heatsink, provides enormous power: The EA-MT4 offers 4 x 100 Watts RMS at 4 Ohms and 2 x 320 Watts RMS bridged, making it a perfect power source for any car audio system.

The Features

The EA-MT4 features an extensive crossover with 12 dB/octave high-pass and low-pass filters. The filters can be adjusted over a very wide range from 20 – 4000 Hz (high-pass) and from 50 – 5000 Hz (low-pass), making the EA-MT4 suitable for active systems as well. The filters can be selected individually and combined into a band-pass filter (HPF + LPF). All controls are hidden under the massive bar with the engraved Emphaser logo. Additional features include RCA and high-level inputs as well as an auto turn-on function for connecting to factory radios without RCA output – making it easy to combine the 4-channel amplifier EA-MT4 with factory-installed radios.
