Frequently Asked Questions about EA-MT1


What power does the Emphaser EA-MT1 Amplifier provide at different resistances?

The Emphaser EA-MT1 provides an output power of 1 x 450 Watts RMS at 4 Ohm and increases the power to 1 x 600 Watts RMS at a resistance of 2 Ohm. This power allows the amplifier to achieve impressive bass reproduction even in a compact format. The Class-D amplifier circuit, combined with the massive aluminum die-cast heat sink, ensures efficient energy conversion and dynamic audio output. The excellent signal fidelity and minimal distortion guarantee powerful playback of any music genre.

What sound optimization features does the EA-MT1 Amplifier from Emphaser offer?

The EA-MT1 Amplifier from Emphaser is equipped with several sound optimization tools. These include a variable subsonic filter (15 – 40 Hz, 12 dB/oct.) to suppress unwanted low frequencies, a low-pass filter (50 – 500 Hz, 12 dB/oct.) to filter out high tones, and a bass boost (0 - 15 dB @ 40 Hz) to enhance bass reproduction. A variable phase shift (0 – 180°) offers additional flexibility in sound optimization, while the auto turn-on function facilitates integration into existing audio systems.

Can I use the Emphaser EA-MT1 with factory-installed car radios?

Yes, the Emphaser EA-MT1 Amplifier is compatible with factory-installed car radios, even without RCA outputs. Thanks to the high-level inputs and the auto turn-on function, the amplifier can be easily integrated. This allows for effortless implementation into various audio systems, enabling significant improvements in sound quality even with conventional radio devices. This is particularly advantageous for drivers who want to maintain the unchanged look of their vehicle but still desire outstanding sound.

What are the dimensions of the EA-MT1 Amplifier from Emphaser?

The EA-MT1 Amplifier from Emphaser measures a compact 212 x 35 x 110 mm. These small dimensions are remarkable for an amplifier with such power capabilities. Despite its compact size, the amplifier impresses with a thoughtful architecture, including the massive aluminum die-cast heat sink that ensures efficient heat dissipation. These features allow for installation in tight spaces, which is advantageous for many vehicle types, without compromising functionality or performance.

What frequency ranges does the Emphaser EA-MT1 support?

The Emphaser EA-MT1 supports a frequency range of 10 Hz to 500 Hz. This range allows the amplifier to efficiently process deep frequencies that are crucial for powerful bass reproduction. The integrated low-pass filter and subsonic filter operate within this spectrum to ensure clean and distortion-free audio playback. Music lovers who value deep and precise bass particularly benefit from the wide frequency capabilities of the amplifier.

What technical details characterize the heat sink of the EA-MT1?

The heat sink of the EA-MT1 is made of solid aluminum die-cast, making it particularly robust and efficient in heat dissipation. This construction supports the Class-D amplifier circuit in achieving high power in a small space. The design promotes the thermal efficiency of the system and minimizes heat accumulation, thereby maximizing the reliability and lifespan of the amplifier. The choice of high-quality material is crucial for stable operation even under maximum power demands.

What connection options does the Emphaser EA-MT1 offer?

The Emphaser EA-MT1 offers both RCA and high-level inputs, making it versatile in use. The auto turn-on function allows for seamless connection to different systems, including factory radios without RCA outputs. This flexibility is particularly valuable when different audio sources are to be used. This is complemented by the variable input sensitivity adjustable from 0.3 to 6 V, allowing you to fine-tune the signal sources and thus ensure ideal sound quality in different environments.

How does the EA-MT1 from Emphaser support bass reproduction?

The EA-MT1 from Emphaser is equipped with a bass boost that is variable from 0 to 15 dB at 40 Hz, optimizing bass reproduction. This feature allows for adjustment of the bass level according to personal preferences or the specific music genre. Additionally, the amplifier circuit supports clear and strong bass output with minimal distortion. This, combined with high output power and finely adjustable filters, provides a concise, powerful sound, especially when playing bass-heavy music.

How does the Class-D amplifier circuit affect the performance of the EA-MT1?

The Class-D amplifier circuit of the EA-MT1 enables highly efficient energy conversion, resulting in great performance while maintaining a compact design. The low heat loss of the Class-D topology minimizes the need for large cooling units, which in turn allows for the small size and portability of the amplifier. This efficiency ensures stable output performance and long durability, even under higher loads. Combined with high-quality components, it guarantees crystal-clear playback quality.

What damping factor does the Emphaser EA-MT1 have and what does it mean?

The Emphaser EA-MT1 has a damping factor of over 400 at 4 Ohm. A high damping factor is important for controlling speakers, as it improves the amplifier's control over the speaker, leading to less distortion and better audio quality. Especially at low frequencies, a high damping factor is crucial for precise bass reproduction. This feature, combined with the amplifier's overall equipment, guarantees an exceptional sound experience.
