Frequently Asked Questions about M-400.1 MD

What power does the M-400.1 MD Amplifier provide at different ohms?

The M-400.1 MD Amplifier from Audio System delivers a power of 1 x 200 Watts RMS at 4 ohms and an impressive 1 x 400 Watts RMS at 2 ohms. These power values are ideal for high-performance applications where you need strong and consistent audio output. The Class D amplifier offers high efficiency, meaning that the power is effectively utilized with minimal losses.

How can I adjust the variable LP filter of the M-400.1 MD?

The M-400.1 MD features a variable LP filter that allows you to set the frequency range in the low frequencies. The low-pass filter can be adjusted in the range of 50 to 150 Hz. This lets you specifically determine which frequencies are passed to your Subwoofer, optimizing the bass to suit your needs. This flexibility is particularly valuable if you enjoy listening to music loudly and desire precision.

What is the function of the Subsonic filter in the M-400.1 MD?

The Subsonic filter of the M-400.1 MD Amplifier is set to 25 Hz and serves to filter out unwanted low-frequency signals that are outside the hearing range. This protects your speakers from unwanted mechanical stress that can arise from very low frequencies. The filter helps improve audio quality and operate the amplifier more efficiently by minimizing distortion and preserving your components.

What is special about the RTC technology in the M-400.1 MD?

The RTC technology in the M-400.1 MD allows for comfortable adjustment of the amplifier's power directly from the driver's seat. This remote control technology enables you to modify the bass intensity and other parameters without needing direct access to the amplifier. This feature offers a high degree of flexibility and comfort in audio playback, especially with changing music or different listening preferences.

How does the automatic power-on mechanism of the M-400.1 MD work?

The M-400.1 MD has a RCA or high-level input with automatic BTL or signal detection that automatically turns on the amplifier as soon as a signal is detected. This means you don't have to manually activate the amplifier every time, allowing for seamless operation. This feature enhances user convenience while also preserving the Battery, as the amplifier is only active when it is actually needed.

What role does SMD technology play in the M-400.1 MD Amplifier?

The SMD technology plays a crucial role in the M-400.1 MD for its compact dimensions and enhanced performance of the Amplifier. By using surface-mounted components, a higher packing density is achieved, which not only saves space but also shortens the signal paths on the circuit board. This leads to improved electrical performance and reduces electromagnetic interference, ensuring clear and high-quality audio enjoyment.

How does the adjustable 0-180° phase shift affect the sound image?

The adjustable phase shift of 0-180° in the M-400.1 MD allows you to optimally align the phase of the Subwoofer with the rest of the Audio System. By adjusting the phase, you can minimize phase cancellations and seamlessly integrate the bass into the overall sound image. This is especially important if you want to personalize the acoustic experience in your car and achieve a perfect crossover frequency between the Subwoofer and speakers.

What are the technical requirements for the power supply of the M-400.1 MD?

The M-400.1 MD requires a power supply cable set of 6mm², which has a length of 5.5m, for optimal operation. Additionally, the Amplifier is equipped with a 25 A Fuse to protect against overloads. A proper power connection is important to fully utilize the performance potential of the Amplifier and to prevent fluctuations in sound quality, especially under higher power demands.

How do I install the M-400.1 MD Amplifier in my vehicle?

When installing the M-400.1 MD, you should consider its compact dimensions of 6.8 x 6.8 x 12.7 cm. These allow for flexible placement in the vehicle, even in tight spaces. Make sure to install the Amplifier in a well-ventilated area to avoid overheating. The included power and signal wiring makes integration easier, and with the automatic signal detection, additional control wiring is eliminated, significantly simplifying the installation of the system.

Which car brands is the M-400.1 MD compatible with?

The M-400.1 MD is widely compatible with various car brands and models thanks to its universal connections and flexible signal reception through high-level inputs. With the RCA connections and compact design, the Amplifier can be integrated into almost any vehicle without requiring specific guidelines from car brands. This facilitates use in different vehicle types and ensures that you can flexibly adapt the Amplifier to your individual needs.
