Its five adjustment bands let an installer or listener raise or reduce selected portions of the audio spectrum rather than relying only on a source unit’s basic tone controls. It is intended for vehicle systems using RCA-level audio connections.\u003c\/p\u003e\u003cp\u003eThis processor is a practical option for drivers upgrading an amplified speaker system or adding a subwoofer amplifier. It provides separate level controls for the overall system, front-to-rear balance, and the subwoofer channel. That arrangement helps tailor output levels from the dashboard instead of requiring repeated amplifier adjustments.\u003c\/p\u003e\u003cp\u003eThe AT-EQ500 uses five graphic-EQ controls centered at 45 Hz, 100 Hz, 700 Hz, 2 kHz, and 15 kHz. Each band offers boost or cut adjustment, allowing measured corrections for bass weight, midrange presence, and high-frequency detail. The control layout is designed for straightforward manual tuning rather than preset-based processing.\u003c\/p\u003e\u003cp\u003eA selectable low-pass section supports the dedicated subwoofer output, with 43 Hz and 63 Hz frequency choices. This allows the subwoofer signal to be managed independently from the front and rear channels. A separate subwoofer-level control makes it easier to match bass output to the rest of the system.\u003c\/p\u003e\u003cp\u003eFor system integration, the equalizer provides three stereo RCA outputs along with auxiliary stereo RCA inputs and an input selector. The front-panel source switch selects between radio and CD inputs, while the fader control adjusts the front-to-rear output balance in a four-speaker arrangement. It fits well as a signal-control stage between an RCA-equipped source and one or more amplifiers.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eFive-Band Graphic EQ:\u003c\/strong\u003e Adjusts five frequency regions for more tailored system voicing.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e±12 dB Tone Range:\u003c\/strong\u003e Allows boost or cut at each equalizer band.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubwoofer Output:\u003c\/strong\u003e Provides a dedicated RCA signal path for a subwoofer amplifier.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Low-Pass Filter:\u003c\/strong\u003e Offers 43 Hz or 63 Hz subwoofer-frequency selection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree Stereo RCA Outputs:\u003c\/strong\u003e Supports multi-channel amplified car-audio system layouts.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSource And Level Controls:\u003c\/strong\u003e Includes input selection, master volume, fader, and sub level.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe AT-EQ500 has a compact black chassis with a front-mounted control layout for direct access to fader, volume, subwoofer level, source selection, subwoofer frequency selection, and equalizer adjustments.

Use the auxiliary stereo RCA inputs and radio\/CD selector only with compatible line-level sources, then route the three stereo RCA outputs to the appropriate amplifier inputs. Set amplifier gains conservatively before making EQ boosts, and use the fader, master volume, and subwoofer controls to balance the completed system.\u003c\/p\u003e","brand":"Audiotek","offers":[{"title":"Default Title","offer_id":45614194688070,"sku":"AT-EQ500","price":54.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/71zamH9V9qL.jpg?v=1784360217","url":"https:\/\/audiowatt.store\/products\/audiotek-at-eq500-5-band-car-audio-graphic-equalizer","provider":"Audio Watt Store","version":"1.0","type":"link"}
