It is installed between a source unit and external amplifiers, making it useful when a system needs more tuning flexibility than basic head-unit controls provide. Dedicated front, rear, and subwoofer outputs support a multi-amplifier system layout.\u003c\/p\u003e\u003cp\u003eThis processor is intended for listeners building or refining an amplified car audio system with separate bass control. Its seven EQ controls address fixed center frequencies from 50 Hz through 16 kHz, helping users adjust bass weight, vocal presence, and high-frequency balance. A master volume control and separate subwoofer-level control make it easier to tailor overall and bass output from the front panel.\u003c\/p\u003e\u003cp\u003eThe EQ770 provides up to 7 volts RMS of output for sending a strong preamp-level signal to compatible amplifiers. Its specified 10 Hz to 50 kHz frequency response, 90 dB signal-to-noise ratio, and 70 dB channel separation support clean signal routing within a properly configured system. The unit uses an onboard 30V bipolar switching power supply.\u003c\/p\u003e\u003cp\u003eFor bass-system integration, the EQ770 includes a selectable low-pass frequency setting at 60 Hz or 90 Hz. This provides a simple way to choose the low-pass point used for the subwoofer output. A front-to-rear fader control is also provided for systems using four speakers.\u003c\/p\u003e\u003cp\u003eSource flexibility includes main, auxiliary, and AUX 2\/MP3 input options, with an AUX\/Main source selector and auxiliary gain control. The EQ770 is a practical upgrade for systems using external amplifiers and RCA signal connections. Its night-illumination design keeps the front-panel controls visible during nighttime driving.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e7-Band Equalizer:\u003c\/strong\u003e Adjusts seven fixed frequency ranges for more detailed tonal tuning.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e7V RMS Output:\u003c\/strong\u003e Sends a high-level preamp signal to compatible external amplifiers.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubwoofer Level Control:\u003c\/strong\u003e Adjusts bass-output level independently from the main volume.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Low-Pass Filter:\u003c\/strong\u003e Offers 60 Hz or 90 Hz subwoofer frequency selection.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree Preamp Output Zones:\u003c\/strong\u003e Provides dedicated front, rear, and subwoofer signal outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAUX and MP3 Inputs:\u003c\/strong\u003e Adds source options beyond the main audio input.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe EQ770 uses a compact under-dash processor layout with front-panel rotary controls for volume, subwoofer level, fader, auxiliary gain, and equalizer adjustment. Its RCA input and output connections are nickel-plated, and the front panel includes night illumination. The control layout places frequently adjusted system settings within easy reach.\u003c\/p\u003e\u003cp\u003eMount the unit beneath the dashboard or on a suitable interior hump using the supplied-style bracket arrangement described in the manual. The wiring diagram routes the main source into the equalizer, then routes front, rear, and subwoofer outputs to their respective external amplifiers; it also requires switched +12V, ground, and remote-turn-on connections. Use the 60 Hz or 90 Hz low-pass selection with the subwoofer amplifier path, then set output levels conservatively during system tuning.\u003c\/p\u003e","brand":"Cerwin Vega","offers":[{"title":"Default Title","offer_id":45614322057286,"sku":"CER-EQ770","price":151.18,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/51iswd0_9GL.jpg?v=1784366277","url":"https:\/\/audiowatt.store\/products\/cerwin-vega-eq770-7-band-parametric-car-audio-equalizer","provider":"Audio Watt Store","version":"1.0","type":"link"}
