EMPHASER EA-M4 - A balance of power and sound

Superior quality, timeless design, unique performance

The performance

Outstanding quality, timeless design, unique performance - the EA-M4 4-channel amplifier from EMPHASER's Monolith series offers not only concentrated power, but also outstanding dynamics and special 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, in conjunction with the massive aluminum heat sink, provides enormous power: The 2 ohm stable EA-M4 is a perfect power source for any car audio system with a remarkable 4 x 105 W RMS at 4 ohms - but scores especially in 2-channel bridge mode with 2 x 340 W RMS and extremely low distortion values.

The design

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

The equipment

The amplifier offers a comprehensive crossover, which is routed optionally as a high or low pass. The crossover is adjustable in 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 are individually selectable and can also be combined: highpass, lowpass and bandpass (HPF+LPF).
