The SoundXtreme ST-AP6 is a digital bass machine processor engineered to significantly enhance the low-frequency response of your car's audio system. It works by digitally restoring and injecting crucial bass information that is often missing from music, transforming your listening experience with deeper, more resonant bass. This processor is ideal for users seeking to achieve the most impactful bass possible from their existing or upgraded sound systems. This unit provides comprehensive control over your bass with its efficient bass equalization circuit. Users can precisely adjust the bass frequency, width, and level to suit their musical preferences. The frequency control allows you to select the specific low frequencies to emphasize, while the width control determines the range of frequencies affected around the selected point. The level adjustment then dictates the intensity of this manipulation, offering granular control over the bass output. For added convenience, the bass level control is accessible via an included dash-mount remote, allowing for on-the-fly adjustments. Key specifications of the ST-AP6 include an output level of 13.5 volts, a wide frequency response of 10Hz to 100kHz, and a high signal-to-noise ratio of 130dB. It boasts balanced input noise rejection of 60dB for a cleaner signal path. The processor features gold-plated contacts to ensure optimal signal transfer and minimize signal loss. Its dimensions are approximately 10.4 x 2.3 x 8.6 inches, designed for integration within a vehicle's dashboard or console area. This device is intended for use in car audio systems to maximize bass performance.
