It is intended for systems that need more adjustment than a conventional bass boost control can provide. The processor lets installers and listeners tune bass character for the vehicle, subwoofer system, and source material.\u003c\/p\u003e\u003cp\u003eA dedicated bass restoration circuit is used to enhance low-frequency content that may be reduced in recordings or playback sources. The SWEEP control selects the center frequency from 27Hz to 63Hz, while the WIDE control adjusts the range affected by the processing. A separate subwoofer level control provides an additional way to set bass output.\u003c\/p\u003e\u003cp\u003eThe STX850W is specified with a 10Hz to 35kHz frequency response, 133dB signal-to-noise ratio, and 0.0025% total harmonic distortion. These published figures describe a processor built to integrate into a full-range car-audio signal chain while focusing its adjustment capability on bass. Balanced RCA inputs are designed to help manage noise in automotive electrical environments.\u003c\/p\u003e\u003cp\u003eIts RCA inputs accept up to 15V RMS and use a 10 kOhm input impedance. The unit is specified for more than 62dB of noise rejection and can deliver up to 13.2V peak through 150-ohm RCA outputs. This makes it suited to systems using an aftermarket source unit, external amplifiers, or both.\u003c\/p\u003e\u003cp\u003eA dash-mount remote is included for bass-level adjustment from the front of the vehicle. The remote has an LED indicator and a PFM subsonic filter switch for reducing very low frequencies outside the intended operating range of the system. The processor operates from a 12V DC automotive electrical system and draws 150mA.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eBass Restoration Circuit:\u003c\/strong\u003e Enhances low-frequency information in the audio signal.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAdjustable Sweep:\u003c\/strong\u003e Selects bass center frequency from 27Hz to 63Hz.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eWide Control:\u003c\/strong\u003e Adjusts the range affected by bass processing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eBalanced RCA Inputs:\u003c\/strong\u003e Supports up to 15V RMS input signals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eDash-Mount Remote:\u003c\/strong\u003e Provides accessible bass-level adjustment and LED indication.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003ePFM Filter Switch:\u003c\/strong\u003e Reduces unnecessary subsonic low-frequency content.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe STX850W uses a separate processor-and-dash-remote layout, allowing the main unit to be placed in the audio system while the level control remains accessible to the driver. Specific enclosure materials are not published. Its design centers on RCA signal connections, front-panel adjustment controls, and a remote-mounted bass control.\u003c\/p\u003e\u003cp\u003eInstall the processor in an RCA signal path between the source unit and the applicable amplifier input, using its balanced RCA inputs and RCA outputs. Connect it to a 12V DC vehicle electrical supply within its specified 11V to 16V operating range, then set SWEEP, WIDE, subwoofer level, and the PFM switch to suit the subwoofer system. Professional installation is recommended when integrating the unit with factory audio electronics or high-output aftermarket equipment.\u003c\/p\u003e","brand":"STX Audio","offers":[{"title":"Default Title","offer_id":45664656261190,"sku":"STX850W","price":49.99,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71ZDsrjN6UL.jpg?v=1784450020","url":"https:\/\/audiowatt.store\/products\/stx-audio-stx850w-digital-bass-processor-with-dash-remote","provider":"Audio Watt Store","version":"1.0","type":"link"}
