Frequently Asked Questions about MA 1

What is the performance of the ETON MA 1 Amplifier at different resistances?

The ETON MA 1 Amplifier offers impressive performance values. It delivers 690 watts at 4 Ohm, creating ideal conditions for high-quality speakers. At an impedance of 2 Ohm, the power increases to 1120 watts, perfect for even more power-intensive applications. If you prefer low-resistance setups, the MA 1 reaches a solid 1510 watts at 1 Ohm. This variability in power output provides flexibility and allows you to tune the amplifier to different speaker configurations. Keep in mind the thermal conditions and the efficiency of the connected speaker systems to achieve the best possible performance.

What special technical features does the ETON MA 1 Amplifier offer?

The ETON MA 1 Amplifier is equipped with Advanced Class-D technology, which combines high efficiency with excellent sound quality. The adjustable high-pass and low-pass filters allow for precise sound control and adjustment to individual needs. The subsonic filter protects your speakers from unwanted frequencies below 30 Hz, which is particularly significant at high volumes. The adjustable high-level input impedance and the variable input signal voltage provide flexibility when connecting to different signal sources. The aluminum die-cast housing not only offers stability but also contributes to effective heat dissipation.

How does the Auto-Sense On function of the ETON MA 1 work?

The Auto-Sense On function of the ETON MA 1 automatically activates the amplifier as soon as an audio signal is detected. This occurs either through the signal or DC voltage detection system (SIG/DC), allowing the amplifier to be ready for operation without manual activation. This function is particularly convenient when the amplifier is installed in a hidden location and accessing the switch is cumbersome. The automation ensures that the amplifier is only turned on when it is actually needed, leading to optimal energy savings. Ideal for systems that are frequently used but should remain discreet.

What mounting options does the ETON MA 1 Amplifier offer?

The ETON MA 1 Amplifier impresses with its versatile mounting options. With variable mounting feet and hidden mounting points, it offers flexibility during installation. The additional blind hole drillings allow you to install the amplifier firmly and securely, even in tight spaces. Furthermore, the amplifier is stackable, meaning you can install multiple units on top of each other without worrying about voltage losses or space issues. This design is ideal for users who want a clean and organized setup without compromising functionality.

What are the connection options of the ETON MA 1 Amplifier?

The ETON MA 1 offers comprehensive connection options through its two high-level inputs and two low-level inputs (RCA). The high-level input signal voltage is adjustable between 1 - 15 V and 15 - 40 V, allowing connection to different sources. The input resistance can be configured per channel pair to 10, 150, or 600 Ohms. The detachable connection plugs facilitate installation and potential reconfiguration, while the integrated level remote control allows for convenient volume control. This thoughtful connection structure ensures optimal adaptation to a variety of audio systems.

What filtering options does the ETON MA 1 Amplifier offer?

The ETON MA 1 Amplifier is equipped with precisely adjustable high-pass and low-pass filters. The low-pass filter is adjustable between 25 and 250 Hz with a slope of 12/24 dB/oct., allowing for targeted tuning to the corresponding speakers. The subsonic filter removes unwanted extremely low frequencies below 30 Hz, protecting the speakers from damage caused by ineffective vibrations. Thus, the filter characteristics of the amplifier provide you with the opportunity to calibrate the sound reproduction exactly and tailor it to your individual listening habits and requirements.

What role does the aluminum housing of the ETON MA 1 Amplifier play?

The aluminum die-cast housing of the ETON MA 1 Amplifier plays a crucial role in terms of durability and thermal management. The robust design in matte gunmetal grey not only provides an aesthetically pleasing appearance but also ensures optimal heat dissipation. Especially under high power demands, the housing prevents overheating of the internal components, contributing to the longevity and reliability of the amplifier. Additionally, it protects the sensitive electronics from mechanical impacts, ensuring functionality even in demanding installation environments.

How does the ETON MA 1 Amplifier perform in terms of signal quality?

The ETON MA 1 Amplifier impresses with high signal quality. The signal-to-noise ratio is an impressive 96.5 dB, ensuring clear sound reproduction with minimal noise. The damping factor at 4 Ohm is over 340, allowing precise control over speaker movement, which is especially important for powerful and precise bass reproduction. With a THD+N rate of only 0.003% at 5 W and 1 kHz, distortion remains at an extremely low level. These specifications ensure that your audio system delivers pure and detailed sound, ideal for audiophile applications.

What are the dimensions of the ETON MA 1 Amplifier and how does that affect installation?

The ETON MA 1 Amplifier has compact dimensions of 270 x 160 x 51 mm, making it a flexible solution for installations with limited space. This compact design is particularly practical for hidden installations or when integrating into tight vehicle cabins. Despite its powerful internals, the size does not compromise performance, allowing for easy and discreet installation without sacrificing sound quality. This is especially advantageous when the amplifier needs to be placed unobtrusively in vehicles or living environments.

What is included in the delivery of the ETON MA 1 Amplifier?

The delivery of the ETON MA 1 Amplifier includes everything necessary for a complete installation and commissioning. Included are the MA 1, a power connector, three speaker connectors, and three high-level cables. These allow for versatile connection options. A remote level control for comfortable volume adjustment and four mounting feet including mounting screws complete the package. This comprehensive equipment ensures that you have all the necessary components at hand to optimally and easily integrate the amplifier into your audio system, whether for home or car audio applications.
