The STX Audio STX850W is a cutting-edge digital bass processor meticulously engineered to enhance low-frequency performance in car audio systems. Unlike traditional bass boost solutions, the STX850W employs a dedicated bass driver circuit that intelligently restores low-frequency content lost during recording, resulting in fuller and more accurate bass reproduction across all audio sources. The bass equalization circuit further refines the restored low-frequency response to perfectly match your specific speaker system. The STX850W's design includes two primary controls that give users exceptional command over bass characteristics. The SWEEP control allows you to select the center frequency of the bass restoration circuit, adjustable between 27Hz and 63Hz, while the WIDE control offers the flexibility to define the breadth of the affected frequency range. Additionally, a dedicated sub volume control enables direct bass output level adjustments, allowing for fine-tuning to suit individual vehicle acoustics and listening preferences. With a frequency response that spans 10Hz to 35KHz, a signal-to-noise ratio of 133dB, and total harmonic distortion as low as 0.0025%, the STX850W guarantees enhanced bass fidelity without introducing unwanted noise or artifacts. Its balanced RCA inputs can accept signals up to 15V rms and feature over 62dB noise rejection through a 10K ohm input impedance, making it fully compatible with both factory head units and powerful aftermarket receivers while effectively minimizing engine and alternator noise. The included dash mount remote control, equipped with an LED indicator that brightens with increased bass output, allows for effortless adjustments from the driver's seat. The PFM subsonic filter switch is designed to eliminate inaudible sub-bass frequencies that can waste amplifier power and put unnecessary stress on speakers. Operating on 12V DC (within an 11-16V range) and drawing only 150mA, the STX850W outputs up to 13.2V peak throu...
