Emphaser EA-M4

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 solid aluminum heat sink, it delivers 4 x 105 W RMS at 4 ohms and 2 x 340 W RMS in 2-channel bridge mode. The carefully machined edges, an engraved logo and the sandblasted surface underline its impressive appearance. In addition, the amplifier offers extensive crossover options, encapsulated 35 mm power terminals and screwed RCA sockets. The EA-M4 is a perfect power source for any car audio system.

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 outstanding dynamics and special signal fidelity. Minimal distortion and a warm, clear sound are characteristics that distinguish this top-of-the-range digital power amplifier. The Class-D amplifier circuit in conjunction with the solid aluminum heat sink ensures enormous performance: The 2-ohm stable EA-M4 is a perfect power source for any car audio system with an impressive 4 x 105 W RMS at 4 ohms - but scores particularly well in 2-channel bridge operation with 2 x 340 W RMS and extremely low distortion values.

The amplifier design underlines the special character of this exceptional amp: the carefully machined edges, the engraved logo and the model name on the top plate, together with the sandblasted surface, create an impressive look. The connections are solid - encapsulated 35 mm power terminals and screwed RCA sockets.

The amplifier offers an extensive crossover that can be routed as either a high-pass or low-pass filter. The crossover range can be set over a very wide control range from 20 Hz (high-pass) and 50 Hz (low-pass) to 5000 Hz and can therefore also be used for active system concepts. The filters can be selected individually and can also be combined: high-pass, low-pass and band-pass (HPF+LPF).
