Frequently Asked Questions about RS-SD300.4D

What RMS power does the RS-SD300.4D Amplifier provide at 2 Ohms?

The RS-SD300.4D from Reiss Audio offers an impressive RMS power of 450 W per channel at 2 Ohms. This allows for powerful audio playback across all four channels and is ideal for demanding car audio setups. The high power supports clean sound reproduction even at higher volumes, which is particularly important for enthusiasts who value clear and penetrating audio performance. This power makes the amplifier an excellent choice for users looking for a powerful audio solution to achieve an impressive listening experience in the car.

What is the total harmonic distortion of the RS-SD300.4D?

The total harmonic distortion (THD) of the RS-SD300.4D Amplifier from Reiss Audio is less than 0.3%. This low distortion rate ensures that the original sound is reproduced without audible distortions. This is crucial, especially at higher volumes, to guarantee a clear and uncolored sound. Minimizing THD optimizes the sound image and highlights the subtle nuances of the music, making the RS-SD300.4D an excellent choice for sound purists who value precise audio quality.

What frequency range does the RS-SD300.4D cover?

The RS-SD300.4D Amplifier from Reiss Audio covers a full frequency range of 20 Hz to 20 kHz. This range corresponds to the human hearing spectrum and ensures that all audio components from bass to treble are reproduced accurately and uncolored. The wide frequency coverage is crucial for a balanced and complete sound image, allowing you to perceive even the finest musical details clearly. Thus, the amplifier is well-suited for hi-fi applications in the car, where a full and detailed soundscape is desired.

What is the S/N ratio of the RS-SD300.4D?

The RS-SD300.4D from Reiss Audio offers a signal-to-noise ratio (S/N ratio) of over 90 dB, measured at 1 watt power at 4 ohms. Such a high S/N ratio means that the Amplifier amplifies the input signal very cleanly and with minimal background noise, which is essential for fidelity during quieter passages. A high S/N value ensures that sound details are not lost in the system's background noise and enhances clarity, especially in quiet music pieces.

What bridge power does the RS-SD300.4D achieve at 4 ohms?

The Reiss Audio RS-SD300.4D achieves an impressive bridge power of 900 W at 4 ohms. This high power is ideal for systems that require a significant power boost, for example, to effectively drive Subwoofers. The bridging configuration utilizes the combined power of two channels to achieve maximum energy efficiency and exceptional sound pressure. Particularly when reproducing bass frequencies, your setup benefits from this power increase, allowing even larger speaker systems to be effortlessly supplied with enough power.

How can the RS-SD300.4D be adjusted regarding input sensitivity?

The RS-SD300.4D Amplifier from Reiss Audio features a variable gain range of 0.2 to 10 V. With this flexible adjustment range, you can precisely set the input sensitivity to optimally match your source device. Correctly adjusting the gain value is essential to avoid distortion and create a harmonious balance between the Amplifier and speakers. This feature helps you fine-tune your audio system so you can achieve the desired volume without compromising sound quality.

For which audio applications is the Class-D topology of the RS-SD300.4D suitable?

The Class-D topology of the RS-SD300.4D Amplifier from Reiss Audio is particularly efficient and is excellent for applications where high performance in a compact design is required. This technology minimizes energy loss in the form of heat, making the amplifier more efficient than traditional Class-AB amplifiers. As a result, the RS-SD300.4D is ideal for mobile use in vehicles, where space and energy consumption are often limiting factors. You benefit from a powerful amplifier that combines excellent audio performance with energy efficiency.

How adjustable is the bass boost of the RS-SD300.4D?

The bass boost of the RS-SD300.4D Amplifier from Reiss Audio offers an adjustment range from 0 to 18 dB. This allows for precise control of bass intensity to tailor the sound exactly to your individual preferences. With the ability to specifically enhance the bass, you can fine-tune the depths of your audio system to match the acoustics of your vehicle and proactively influence the musicality. Especially with bass-heavy tracks, a higher bass boost can create a more powerful and immersive sound experience.

What is the significance of the Cruzials crossover of 12 dB in the audio setup?

The Cruzials crossover of 12 dB in the RS-SD300.4D emphasizes the transition slope between frequency bands. This functionality allows for a smooth blending of frequency ranges, optimizing the overall sound image. A 12 dB/octave filter provides a moderate attenuation of frequencies that lie outside the desired range, resulting in a clearer and cleaner sound. This is particularly useful for crossovers in audio setups to improve playback efficiency while minimizing impurities in the sound spectrum.

How can the RS-SD300.4D be installed in the car?

The installation of the RS-SD300.4D in the car can be flexibly designed given its compact dimensions. You can mount the amplifier, for example, under the seat, in the trunk, or in a side pocket, as long as adequate ventilation is ensured. It is important to carefully measure the exact installation space to ensure that there is enough room to avoid heat buildup and securely fasten the components, which guarantees reliable function in the long term. Its compact shape significantly facilitates integration into existing car audio systems.

Top für den Preis !!!

Hören sich gut an!!! hätte ich nicht gedacht in der Preisklasse, vor allem der Pegel hab sie mit paar Axton Hochtönern verbaut und einem Kicker sub im Kofferraum und paar Rainbow Endstufen sauberer lauter klang bin sehr zufrieden mit dem Produkt. Langzeit noch keine Erfahrung da erst zwei Wochen verbaut

Versterker was goed verpakt, En heb dit beest heeft zo veel power!

Versterker was goed verpakt, En heb dit beest gelijk getest op volume en klinkt geweldig op mijn subwoofers, Het geluid vervormd niet zelfs op vol volume klinken de bas tonen zuiver, Ben vooral blij dat ik deze versterker gekocht heb. Ik geniet van elke seconde in mijn auto,Ik kon het merk niet van de versterker [gs-audio] maar het is top merk en het is met de hand gemaakt en komt uit Italy is echt goed gemaakt alleen mijn auto heeft het zwaar te verduren alles beweegt, Dus top aankoop gedaan.
