The Audio System R-1250.1 D amplifier is a 1-channel amplifier with remarkable output power. At an impedance of 4 ohms, it delivers 500 watts RMS. Reducing the impedance to 2 ohms increases the power to 900 watts RMS. The maximum power output is achieved at 1 ohm with 1250 watts RMS. These power levels make the R-1250.1 D an ideal amplifier for subwoofers that require high power and precision. With its digital amplifier technology, it can efficiently convert power while achieving an efficiency of up to 84%.
The R-1250.1 D from Audio System offers various features that significantly improve the sound quality in the vehicle. The built-in low pass filter allows for precise adjustment of the frequencies sent to the subwoofer, eliminating unwanted high frequencies. The subsonic filter protects the subwoofer from very low frequencies that could damage it. Additionally, the 0-180° phase shift can be continuously adjusted to optimize the timing of the audio output, ensuring perfect sound alignment in the vehicle. Together, these features maximize the car's audio system.
The R-1250.1 D offers a variety of adjustment options for sound fine-tuning. The low pass filter can be set to forward only the desired bass frequencies to the subwoofer. The integrated subsonic filter protects the subwoofer from extremely low frequencies that could be harmful to the speaker equipment by cutting them off below a certain threshold. A particularly impressive feature is the continuously adjustable 0-180° phase shift, which dynamically adjusts the soundstage to avoid timing issues, ensuring harmonious playback.
The amplifier Audio System R-1250.1 D measures a compact 380 x 50 x 185 mm. This allows for flexible placement in the vehicle, whether under a seat or at the side of the trunk. As a 1-channel mono amplifier, it is particularly suitable for installation at subwoofer positions that require high power. Thanks to its low height of only 50 mm, it can also be installed in tight spaces, as long as ventilation for the cooling process is ensured. Its compact dimensions allow for discreet integration of the amplifier without compromising the interior.
The SMD (Surface Mounted Device) technology in the R-1250.1 D amplifier enables a compact design characterized by more efficient space utilization and improved heat dissipation. This leads to higher reliability of electronic components, as surface mounting provides tighter connections and greater mechanical stability. Additionally, SMD technology minimizes electromagnetic interference, improves signal integrity, and enhances overall performance. These are crucial factors for the excellent audio quality that the R-1250.1 D offers.
The integrated bass EQ at 45 Hz in the R-1250.1 D amplifier allows for targeted boosting of the bass level, particularly emphasizing the lows and expanding the sound volume. With an adjustment range of 0 to 6 dB, this EQ offers versatile options for customizing the sound profile. Especially if you enjoy listening to music with intense bass, the bass EQ enables fine-tuning of the lows to achieve maximum sound intensity without compromising audio quality. This results in a rich and powerful bass that enhances the overall audio experience.
The high-level input of the R-1250.1 D allows compatibility with factory car radios that do not have line outputs. The amplifier can automatically turn on as soon as an audio signal is detected, ensuring seamless integration and user-friendliness. This feature is particularly advantageous if you want to use the amplifier in a vehicle that has an unmodified factory system. The high-level input ensures that no additional adapters are needed to integrate the amplifier into existing systems.
The Audio System R-1250.1 D amplifier is particularly efficient thanks to its digital amplifier technology, which enables an efficiency of up to 84%. This high efficiency means that the amplifier converts less energy into heat, thus being able to deliver more power into actual sound. This is not only resource-saving but also reduces the need for extensive cooling systems. The ability to deliver high power with minimal energy loss makes the R-1250.1 D an excellent choice for powerful yet energy-efficient audio systems.
The continuously adjustable 0-180° phase shift in the R-1250.1 D amplifier plays a crucial role in sound optimization in the vehicle. By being able to adjust the phase, the time offset between the front speakers and the subwoofer can be precisely set. This is important to avoid acoustic interferences or phase issues that could lead to a delayed or unclear sound image. Especially in more complex audio systems, the phase shift can help improve the coherence and impact of the bass range.
The R-1250.1 D amplifier does not offer an explicit high-pass filter, but focuses on low pass and subsonic filters. With the subsonic filter, you can limit the frequencies so that only significant bass frequencies are passed on to the subwoofer. This approach protects the speaker from vibrations and unwanted noises that could arise from very low tones. The low pass filter allows for fine-tuning of which frequencies ultimately reach the subwoofer, supporting the high-pass approach in conventional applications and protecting the system from overload.
