The RPX-B812 from Rebec offers a variety of inputs and outputs. The inputs include USB playback, optical/coaxial inputs with 192 kHz, Bluetooth, as well as 2-channel low-level and 12-channel high-level inputs. The outputs include an 8-channel high-level output and a 12-channel low-level output. The RCA output voltage is also noteworthy at 2.2 V. This variety of connectivity options ensures maximum flexibility in use, whether for complex audio installations or simply high-quality music playback. This makes the RPX-B812 ideal for various applications in vehicle audio amplification.

What power does the Rebec RPX-B812 DSP Amplifier provide?

The RPX-B812 DSP Amplifier from Rebec delivers an impressive RMS output power of 8 × 50 W at 4 Ω. This power allows for a rich and dynamic sound, ideal for high-quality music and audio applications. The amplifier offers a frequency response of 20 Hz to 20 kHz, covering most audible tones, and its DSP sampling rate of 48 kHz ensures precise sound processing. The signal-to-noise ratio of 94 dB and the distortion factor of less than 0.09% also contribute to the exceptional sound quality. The RPX-B812 is thus well-suited for demanding audio tasks.

What is the frequency response of the Rebec RPX-B812?

The Rebec RPX-B812 offers a frequency response of 20 Hz to 20 kHz, which corresponds to the standard range of human hearing. This wide frequency response ensures that the Amplifier reproduces all sounds, from deep bass to high treble, clearly and in detail. This is especially important for music lovers who want to enjoy every nuance of their music. Additionally, the DSP sampling rate of 48 kHz guarantees precise audio playback, minimizing distortion and maximizing sound fidelity. This frequency range makes the RPX-B812 ideal for use in high-fidelity audio applications.

What Bluetooth version does the RPX-B812 support?

The RPX-B812 DSP Amplifier from Rebec is equipped with Bluetooth version 5.4. This newer version of Bluetooth offers several advantages over previous versions, such as higher transmission speed, improved range, and lower power consumption. This enables reliable and high-quality wireless audio transmission, ideal for use in vehicles or home applications where interference-free connectivity via Bluetooth is required. The Bluetooth functionality is particularly convenient for wireless connection with smartphones, tablets, or other Bluetooth-enabled devices.

How is the RPX-B812 installed in the car?

Installing the Rebec RPX-B812 in the car is straightforward, but it requires consideration of certain technical aspects. The Amplifier offers flexible connection options and requires an operating voltage of 10 to 16 V. The installation position should be chosen to ensure that the Amplifier is well-ventilated and does not overheat. During installation, the specific inputs and outputs must be correctly connected to ensure full power and excellent sound quality. Furthermore, the Amplifier should be securely mounted to minimize vibrations and movement while driving. Precise dimensions were not specified in the product description.

What is the signal-to-noise ratio of the RPX-B812?

The signal-to-noise ratio (SNR) of the Rebec RPX-B812 is an excellent 94 dB. A high SNR value is crucial for audio quality as it indicates how well the amplifier can separate the desired audio signal from background noise. A value of 94 dB shows that the RPX-B812 is capable of delivering very clear and distortion-free audio signals, which is particularly important for applications where high sound fidelity is required. This high signal-to-noise ratio helps ensure that music and other audio data are reproduced in their original quality.

What RCA output voltage does the RPX-B812 offer?

The Rebec RPX-B812 DSP amplifier provides an RCA output voltage of 2.2 V. This voltage is sufficiently high to transmit high-quality audio signals to external amplifiers or other audio output devices without the need for additional signal amplification. A higher output voltage can positively influence signal transmission by reducing susceptibility to interference and enabling cleaner and unaltered audio quality. This is especially important in audio systems where multiple components are connected to ensure optimal performance with minimal signal loss.

What is the total harmonic distortion of the RPX-B812?

The Rebec RPX-B812 DSP amplifier has a total harmonic distortion of less than 0.09% at both its low-level and high-level outputs. A low total harmonic distortion is particularly important for audio quality as it indicates how little distortion occurs when amplifying the audio signal. A total harmonic distortion of less than 0.09% means that the distortions are so low that they are practically imperceptible to the human ear, ensuring an unaltered reproduction of the original signal. This characteristic is crucial for applications that demand high sound fidelity.

What DSP sampling rate does the RPX-B812 use?

The Rebec RPX-B812 uses a DSP sampling rate of 48 kHz. This sampling rate is an important factor for audio quality as it determines how often the analog signal is digitally sampled. A sampling rate of 48 kHz means that the audio signal is sampled 48,000 times per second, resulting in a detailed reproduction of the original audio signal. This high sampling rate helps ensure that the RPX-B812 can deliver clear and precise sound processing even with complex audio signals, which is beneficial in numerous applications, whether in a car or other audio installations.
