A good Amplifier not only delivers watts, it controls your speakers. Many mainstream amps dazzle with high numbers but lose stability under load. Our selection of power amplifiers from Deaf Bonce and DD Audio stands for honest power ratings and maximum efficiency – so your system plays cleanly even at the limit.
EA-M4X by Emphaser Description
The 4-channel amplifier EA-M4X from Emphaser delivers impressive power and dynamics with minimal distortion for a clear, warm sound. With its 230 watts RMS per channel at 4 ohms and 670 watts RMS in bridged mode, it impresses with its power. The sandblasted design with engraved logo and solid terminals emphasizes its high-quality character. The integrated crossover allows for flexible settings suitable for various audio applications. A massive aluminum heat sink ensures efficient heat dissipation.
Performance
The 4-channel amplifier EA-M4x from the Monolith Series by Emphaser not only offers concentrated power, but also outstanding dynamics and exceptional signal fidelity. Minimal distortion as well as a warm, clear sound are features that distinguish this top-of-the-line digital amplifier. The Class-D amplifier circuit, in combination with the massive aluminum heat sink, delivers enormous performance: The 2-ohm stable EA-M4x already provides an impressive 4 x 230 watts RMS at 4 ohms, and a powerful 2 x 670 watts RMS in bridged mode.
Design
The amplifier design highlights the special character of this exceptional amp: The carefully finished edges, the engraved logo and model designation on the top plate, together with the sandblasted surface, create a striking appearance. The terminals are also solid – encapsulated 35 mm power terminals and screwed RCA sockets.
Features
In terms of features, this amplifier offers an extensive crossover, which can be routed as either a high-pass or low-pass filter. The crossover range can be set within 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 as well. The filters can be selected individually and also combined: high-pass, low-pass, and band-pass (HPF+LPF).
