Frequently Asked Questions about S2-A100.4

What are the performance features of the Ai-Sonic S2-A100.4 at 2 Ohms?

The Ai-Sonic S2-A100.4 delivers impressive effective power at an impedance of 2 Ohms. With an output voltage of 12V and a Total Harmonic Distortion (THD) of under 1%, the amplifier provides 4 x 165 Watts RMS. These performance specifications demonstrate that the amplifier is capable of producing a strong and clear sound image, even under maximum load. The S/N ratio of over 105 dB ensures minimal background noise, allowing you to enjoy the full sound quality. These parameters make it very attractive for those who place a high value on sound fidelity.

How does the Ai-Sonic S2-A100.4 differ in effective power at 4 Ohms?

At an impedance of 4 Ohms, the Ai-Sonic S2-A100.4 delivers an effective power of 4 x 110 Watts RMS with a Total Harmonic Distortion (THD) of under 1% at 12V. At this impedance and through the use of Class AB technology, the amplifier can provide efficient energy transfer with high thermal stability. The increased impedance option allows for finer adjustments to different speaker conditions and maximizes linear frequency reproduction. The significantly reduced THD of under 0.02% at 4 Ohms also speaks to excellent sound fidelity that will impress even the most demanding music enthusiasts.

What frequency ranges does the Ai-Sonic S2-A100.4 amplifier cover?

The Ai-Sonic S2-A100.4 is capable of covering a wide range of frequencies. The bandwidth for the amplifier ranges from 10 Hz to 40 kHz, ensuring nearly complete coverage of the audible spectrum. With the low-pass settings, the frequency can be adjusted between 50 Hz and 5 kHz depending on the selected multiplier. The high-pass settings vary from 12 Hz to 5 kHz, depending on whether the front or rear high-pass adjustment is used. This variety in frequency settings allows for individual adjustments for precise sound and optimized performance in a stereo setup.

What safety and display features does the Ai-Sonic S2-A100.4 amplifier have?

The Ai-Sonic S2-A100.4 Amplifier includes several safety and display features that assist during use. The included optional remote control shows three LED indicators for protection, power, and clipping, which provide you with information about the operating status. The clipping indicator helps avoid sound distortions, while the protection mode prevents overloads. When powered on, the Ai-Sonic logo lights up, an additional indicator that signals readiness for operation. These integrated safety mechanisms offer an increased level of control and security, ensuring an optimal listening experience at all times.

What input and output options does the Ai-Sonic S2-A100.4 offer?

The Ai-Sonic S2-A100.4 offers a variety of input and output options to adapt to different systems. The input sensitivity ranges from 0.5 to 6V, allowing for flexible integration with various audio sources. This adaptability is ideal for ensuring the best possible sound transmission without signal loss. The amplifier channels provide the option to operate in either a 2-channel or a 4-channel mode. Additionally, the bridging settings of 2 x 330 watts RMS at 4 ohms allow for a power boost for specific applications if a more intense sound reproduction is desired.

What are the dimensions of the Ai-Sonic S2-A100.4 and what does that mean for installation?

The Ai-Sonic S2-A100.4 measures 183 mm in width, 60 mm in height, and 444 mm in length. These compact dimensions allow for easy installation in a variety of vehicles and sound system configurations. When it comes to finding the optimal installation location, these dimensions can help save space in tight vehicle environments without compromising performance. For example, you could easily mount it in the trunk or under the seats, keeping the amplifier accessible while being discreetly installed without disturbing the vehicle's interior.

What power supply layout does the Ai-Sonic S2-A100.4 use?

The Ai-Sonic S2-A100.4 uses a voltage range layout of 10 to 16V, allowing for adaptation to different vehicle systems. The power supply fuse consists of 2 x 40A to guarantee a stable and uninterrupted power supply. This layout is particularly significant if you want to use the Amplifier in various vehicle types. The ability to adapt to different voltage levels provides high flexibility in design and ensures that the Amplifier delivers consistently high performance in both basic and heavily modified audio systems.

Does the Ai-Sonic S2-A100.4 offer a bass boost option?

Yes, the Ai-Sonic S2-A100.4 offers a bass boost option of 0/6 dB at 45 Hz. This bass boost is ideal for those who want to further adjust their sound reproduction in the low-frequency range. The adjustability allows you to optimize the Amplifier for bass-intensive music genres as well as for a generally balanced sound profile. Especially if you enjoy listening to loud music with deep bass sounds, this adjustable bass boost provides the opportunity to enhance the sound experience and maximize your everyday enjoyment of music.

How does the crossover function of the Ai-Sonic S2-A100.4 affect the sound?

The Ai-Sonic S2-A100.4 integrates a crossover function with a slope of 12 dB/octave, allowing for precise differentiation between navigation, Subwoofer, and other speakers. This function helps optimize the sound by directing specific frequencies to the appropriate drivers. This precision is crucial to avoid distortion and ensure harmonic balance in the audio output. Thus, a clear separation of audio frequencies is achieved, which directly results in higher sound clarity and improved music reproduction. These features are essential for an audiophile experience.

Does the Ai-Sonic S2-A100.4 Amplifier fit in common car models?

The Ai-Sonic S2-A100.4 Amplifier dimensions of 183mm x 60mm x 444mm allow it to be installed in a variety of car models. Due to its compact size, the Amplifier is suitable for installation in sedans, station wagons, or SUVs, which are often popular among car audio enthusiasts. Before installation, accessibility to the power supply system should be considered to ensure seamless integration. This size adaptability facilitates installation in different vehicle types, especially those designed for car audio upgrades. Check in advance if there is enough space for proper ventilation.

vibe powerbox65.4m v7 samen met quadlock connector besteld.

Levertijd prima in orde.

vibe powerbox65.4m v7 in mijn vrachtwagen Volvo Fmx 2024 gemonteerd met Quadlock.
Alleen plug and play super fantastisch systeem. Alles standaard op 12v geen omvormer of iets nodig.
In bouw tijd ongeveer 30 minuten.
Radio verwijderen connectors verbinden vibe powerbox65.4m v7 aansluiten.
Alle originele radio instellingen op nul of uit gezet. Volume op 3/4 langzaam de powerbox65.4m v7 open draaien en al het werk laten doen.
Perfect kristal helder geluid in combinatie met mijn Rockford t142 en Rockford p1650 speakers. De bass geluid is verbeterd maar voor echte diepe baas waar ik persoonlijk niet zo van ben heb je echt een externe subwoofer nodig.
Kortom een goede upgrade van je radiogeluid is gegarandeerd.

Masori was goed met de prijs, perfecte communicate met hun gehad. Een echte aanrader.

Used as replacement to Škodas canton system

Used as replacement to Škodas canton system subwoofer.
Works great, fits right into the factory box, need to remove only one little pin and use new skrews.
Sound is even better then it was before.
Plug and play for that system.

Richtig guter Tiefmitteltöner mit Alu-Gusskorb

Richtig guter Tiefmitteltöner mit Alu-Gusskorb und um 30Hz niedrigerer Resonanzfrequenz als üblich im 10cm-Woofer-Bereich. Dadurch kann sich dieser 10cm-Woofer auch wirklich Tiefmitteltöner nennen.

Real power

Ziet er goed uit,Heb 2 accu`s aangesloten, Daar tussen Stinger scheidingsrelais van 200 amp,
Ook moet je 2x zekering van 200 amp plaatsen,

Heb bewust voor Stinger 200 ampere gekozen omdat ik een standaard dynamo heb is dat voldoende.
