The EA-M4 4-channel amplifier from Emphaser combines outstanding quality with timeless design and unique performance. Equipped with a Class-D amplifier circuit and a massive aluminum heat sink, it delivers 4 x 105 watts RMS at 4 ohms and 2 x 340 watts RMS in 2-channel bridged mode. The carefully finished edges, an engraved logo, and the sandblasted surface emphasize its impressive appearance. Additionally, the amplifier offers extensive crossover options, encapsulated 35 mm power terminals, and screw-down RCA sockets. The EA-M4 is a perfect power source for any car audio system.

The Performance

Outstanding quality, timeless design, unique performance – the 4-channel amplifier EA-M4 from the Monolith series by Emphaser not only offers concentrated power, but also exceptional dynamics and remarkable signal fidelity. Minimal distortion as well as a warm, clear sound are characteristics that distinguish this top digital power amplifier. The Class-D amplifier circuit, combined with the massive aluminum heat sink, ensures enormous performance: The 2-ohm stable EA-M4, with an impressive 4 x 105 watts RMS at 4 ohms, is a perfect power source for any car audio system – but it truly excels in 2-channel bridged mode with 2 x 340 watts RMS and extremely low distortion values.

The Design

The amplifier design emphasizes the special character of this exceptional amp: The carefully crafted edges, the engraved logo, and the model designation on the top plate, combined with the sandblasted surface, create an impressive look. The connections are solid – encapsulated 35 mm power terminals and screwed RCA jacks.

The Features

The amplifier offers an extensive crossover that can be routed as either a high-pass or low-pass filter. The crossover range is adjustable over a very wide range from 20 Hz (high-pass) and 50 Hz (low-pass) up to 5000 Hz, making it suitable for active system concepts. The filters can be selected individually and also combined: Highpass, Lowpass, and Bandpass (HPF+LPF).
