Frequently Asked Questions about 400.4 EVO 6.0

What performance specifications does the Soundigital 400.4 EVO 6.0 Amplifier offer?

At an impedance of 4Ω, the Soundigital 400.4 EVO 6.0 delivers an output power of 2 x 66W RMS. If the impedance increases to 2Ω, the power rises to 4 x 100W RMS. The bridged power reaches an impressive 2 x 200W at a 4Ω load. These performance specifications demonstrate that the amplifier is capable of meeting the demands of various speaker configurations. It is also significant that with a bridged power of 2 x 200W, you can generate substantial pressure in your audio system, which is particularly interesting for listeners who prefer volume and clarity.

What frequency range does the 400.4 EVO 6.0 Amplifier cover?

The Soundigital 400.4 EVO 6.0 Amplifier features a wide frequency range of 8Hz to 20kHz, enabling it to reproduce a comprehensive audio spectrum. Both low-pass and high-pass filters are configured at 80Hz, meaning that frequencies above and below this range are efficiently managed. This filtering enhances sound clarity by reducing potential distortions, which is especially beneficial in demanding listening environments. Thus, the 400.4 EVO 6.0 offers precise and controlled sound reproduction across the entire audible range.

What is the current consumption of the Soundigital 400.4 EVO 6.0?

The current consumption of the Soundigital 400.4 EVO 6.0 Amplifier during music operation is 20A, while the maximum current requirement is 40.5A. This is a crucial factor when planning your car audio installation, as the power supply must be stable and adequately sized to optimally operate the amplifier. A recommended fuse of 25A should be installed to ensure both protection and performance. Note that a battery with a minimum capacity of 40Ah is required to secure constant power and avoid sudden voltage drops.

How efficient is the Soundigital 400.4 EVO 6.0?

The overall efficiency of the Soundigital 400.4 EVO 6.0 is 78%, ensuring an efficient conversion of input energy into output power without significant losses. This means that the amplifier dissipates less energy in the form of heat, which is important in compact installations to avoid thermal issues. The high damping factor of 200 at 100Hz nominal impedance ensures controlled diaphragm movements of the speakers, which in turn clarifies the sound and minimizes distortion. An efficient heat management process is thus integrated.

What operating voltage does the 400.4 EVO 6.0 amplifier require?

The Soundigital 400.4 EVO 6.0 amplifier can operate within a voltage range of 9V to 16V, making it compatible with most automotive power systems. This flexibility means you can use the amplifier in a variety of vehicle systems that operate within this voltage range. The ability to work stably even at lower voltages increases the versatility of the amplifier for different applications and vehicle types. This is particularly useful in situations where the vehicle battery voltage may vary.

How can the frequency range of the amplifier be adjusted?

The 400.4 EVO 6.0 features integrated low-pass and high-pass filters, both set at 80Hz and each operating with a filter slope of 12dB/octave. You can use these filters to adjust the frequency response of the speakers to cut off unwanted frequencies. This is especially helpful if you want to clarify the sound and maximize the performance of a subwoofer or satellite system. The filter settings are factory-tuned, allowing for effective changes to the audio output.

What cable cross-sections are recommended for the connection?

For powering the Soundigital 400.4 EVO 6.0, 6mm² heavy-duty cables are required, while 2 x 1.5 mm² cables are recommended for the speaker connections. These cable dimensions ensure that the amplifier can utilize its full power without losses in voltage transmission. At the same time, using appropriate cable cross-sections prevents overloading and heating of the cables. This is crucial to ensure a durable and stable connection and to maintain the efficiency of the system.

What is the signal-to-noise ratio of the 400.4 EVO 6.0?

The signal-to-noise ratio (SNR) of the Soundigital 400.4 EVO 6.0 is 94dB. A higher SNR means improved clarity of audio signals, as it minimizes unwanted background noise. This is especially important at lower volumes, where noise may be perceived more strongly. This high SNR value is an indicator of the excellent audio quality you can expect from this amplifier, even in challenging acoustic environments. This ensures that the sound remains clean and low in noise.

What are the dimensions of the Soundigital 400.4 EVO 6.0, and how does that affect installation?

The amplifier is designed with compact dimensions of 107x86x46mm. The form factor makes installation easy in almost any vehicle, even in tight spaces. Since the amplifier weighs only 0.437 kg, its placement can be versatile, even in locations with limited mounting options. When installing, you should ensure that there is adequate ventilation to efficiently dissipate heat and thus maintain the amplifier's performance over time. Compact yet powerful describes this amplifier perfectly.

How do I adjust the input sensitivity of the 400.4 EVO 6.0?

The input sensitivity for the Soundigital 400.4 EVO 6.0 can be varied between 0.2V and 2V. This range provides the flexibility to adapt the amplifier to different sources such as head units or DAPs. When adjusting, it is important to choose the sensitivity so that the amplifier can deliver maximum power without hitting the limit. This prevents distortion and optimizes sound quality. A common approach is to set the source volume to a medium level and adjust the sensitivity until the desired volume is reached without clipping.
