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.

Frequently Asked Questions about EA-MT4

What output power does the Emphaser EA-MT4 Amplifier offer?

The 4-Channel Amplifier EA-MT4 from Emphaser provides an output power of 4 x 100 Watts RMS at 4 Ohm. In bridged mode, it delivers 2 x 320 Watts RMS, ideal for powerful car audio system combinations. Additionally, it can achieve an output power of 4 x 150 Watts RMS at 2 Ohm, making it optimal for applications with varying loads. This performance is optimized by the Class-D amplifier circuit and the massive aluminum die-cast heat sink, which ensures efficient temperature management and thus high performance in a compact space.

What frequency ranges does the Emphaser EA-MT4 Amplifier cover?

The EA-MT4 Amplifier from Emphaser has a comprehensive frequency range of 10 Hz to 55 kHz. This wide range allows for the reproduction of deep bass to the finest highs, resulting in a detailed and dynamic sound experience. Moreover, the extensive Crossover allows for separate use of high-pass and low-pass filters and offers a control range of 20 Hz to 4000 Hz (high-pass) and 50 Hz to 5000 Hz (low-pass). Such flexibility makes the amplifier the perfect choice for demanding sound installations.

What distinguishes the heat sink design of the Emphaser EA-MT4?

The heat sink design of the Emphaser EA-MT4 is made of massive aluminum die-cast and is characterized by its ability to efficiently dissipate heat. This allows for maintaining performance even in tight installation conditions, supported by the compact dimensions of 212 x 35 x 110 mm. The massive heat sink significantly contributes to the long lifespan of the amplifier by minimizing heat generation under load, thus enabling constant output power. This design is also stylishly executed and integrates the Emphaser logo on the cover.

How does the Emphaser EA-MT4 ensure high sound quality?

The Emphaser EA-MT4 ensures high sound quality through the combination of a very linear frequency response from 10 Hz to 55 kHz and a signal-to-noise ratio of over 90 dB, allowing even the finest audio details to be reproduced precisely. The high channel separation of over 60 dB creates outstanding spatiality and accurate placement of sound events, while the low distortion values allow the music collection to unfold in all its details. The Class-D circuitry used ensures efficiency and minimizes power losses, resulting in a dynamic and powerful sound.

What filter options does the Emphaser EA-MT4 offer?

The Emphaser EA-MT4 is equipped with variable high-pass and low-pass filters that provide a comprehensive adjustment range: the high-pass is adjustable from 20 Hz to 4000 Hz, and the low-pass from 50 Hz to 5000 Hz. These 12 dB/octave filters can be combined into a bandpass filter by activating both simultaneously, allowing for customized sound tuning. This enables the amplifier to be flexibly adapted to different car audio setups, whether for bass optimization or for targeted separation of frequency spectra for specific speaker systems.

How easy is the installation of the Emphaser EA-MT4 in the car?

The installation of the Emphaser EA-MT4 amplifier in the car is extremely user-friendly, thanks to its compact dimensions of 212 x 35 x 110 mm. These allow for flexible placement even in limited space conditions. The 20 mm power connection terminals ensure a stable electrical connection, while the RCA and high-level inputs, including the auto turn-on function, simplify integration into existing systems, even when using original car radios without RCA outputs. Particularly in tight spaces, the aluminum die-cast heat sink offers significant advantages in heat dissipation.

Is the Emphaser EA-MT4 compatible with common car brands?

The Emphaser EA-MT4 can be used in many home car audio setups due to its versatility with RCA and high-level inputs. These allow for extensive compatibility with most car brands, although no specific models are mentioned in the product description. The auto turn-on function is particularly designed to integrate preamplifiers into vehicles that use standard radios, making it easy to incorporate even in older vehicle models without modern audio connections.

What input signal options does the Emphaser EA-MT4 offer?

The Emphaser EA-MT4 Amplifier is equipped with both RCA and high-level inputs, allowing for flexible integration into various car audio systems without being limited by the head unit used. The varying input sensitivity of 0.3 to 10 V enables it to process different signal levels, so the amplifier can be paired with very different source devices. These features facilitate seamless connection to factory-installed radios, especially thanks to the integrated auto-turn-on function that automatically powers on the amplifier when an audio signal is detected.

What technical specifications characterize the Emphaser EA-MT4?

The Emphaser EA-MT4 is marked by specific technical data that contribute to its sound performance. In addition to its various output powers, it is stable at 2 Ohm, allowing it to be flexibly adapted to different subwoofer configurations. Its damping factor at 4 Ohm is over 400, ensuring precise control over the speaker membranes. Another aspect is the wide frequency range of 10 Hz to 55 kHz, which enables deep and balanced sound reproduction. The amplifier is designed with a signal-to-noise ratio of over 90 dB, ensuring clean and distortion-free audio output.

How are the filter functions of the Emphaser EA-MT4 operated?

The operation of the filter functions on the Emphaser EA-MT4 is done via knobs that are hidden under a solid bar featuring the engraved Emphaser logo. This bar protects the knobs from accidental adjustment and provides quick access for finely tuned sound optimization. Additionally, the possible combination of high-pass (20 - 4000 Hz) and low-pass (50 - 5000 Hz) allows for flexible adjustment of the crossover frequency according to the individual requirements of the sound system. Accurate setting of these filters is crucial to optimally match the amplifier output to the car audio setup.
