It fits between compatible line-level source outputs and amplifiers, allowing the user to adjust tonal balance, output levels, and crossover points from one central processor. It is intended for custom car-audio installations rather than as a replacement radio or speaker amplifier.\u003c\/p\u003e\u003cp\u003eThis processor is a practical choice for listeners who want to refine bass, midrange, and treble response beyond the adjustments available on many source units. Its four EQ controls operate at 45 Hz, 120 Hz, 2.2 kHz, and 12 kHz, covering sub-bass, mid-bass, midrange, and treble regions. The controls allow up to 18 dB of cut or boost for system tuning.\u003c\/p\u003e\u003cp\u003eThe HFEQ-2 supports two stereo unbalanced line-level input channels, allowing selection between two connected audio sources. Input-level controls help match the processor to the source unit's line-level sensitivity, while the master volume control adjusts overall audio level. A separate subwoofer level control provides convenient adjustment of the subwoofer output level.\u003c\/p\u003e\u003cp\u003eFor systems using separate amplification, the HFEQ-2 provides front, rear, and subwoofer output channels. The front and rear outputs use high-pass filtering, while the dedicated subwoofer output uses low-pass filtering when the crossover is engaged. A front-to-rear fader and a stereo\/mono subwoofer-output selection add flexibility for common multi-channel system layouts.\u003c\/p\u003e\u003cp\u003eThe processor uses a 1\/2-DIN chassis that can be installed in the dash or under the dash using the included mounting hardware. Its illuminated control knobs can be set to red or blue to suit the vehicle interior. With a maximum output voltage above 9 volts and a specified signal-to-noise ratio above 100 dB, it can serve as a signal-management upgrade in a compatible RCA line-level car-audio system.\u003c\/p\u003e\u003ch3\u003eKey Features\u003c\/h3\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003e4-Band Equalizer:\u003c\/strong\u003e Adjusts sub-bass, mid-bass, midrange, and treble response.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eTwo Source Inputs:\u003c\/strong\u003e Selects between two connected stereo line-level sources.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eActive Crossover:\u003c\/strong\u003e Separates high-pass front\/rear and low-pass subwoofer signals.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eThree Output Zones:\u003c\/strong\u003e Provides dedicated front, rear, and subwoofer outputs.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSubwoofer Level Control:\u003c\/strong\u003e Lets you adjust bass output from the processor.\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eSelectable Knob Illumination:\u003c\/strong\u003e Switches illuminated controls between red and blue.\u003c\/li\u003e\n\u003c\/ul\u003e\u003ch3\u003eDesign \u0026amp; Installation\u003c\/h3\u003e\u003cp\u003eThe HFEQ-2 uses a compact 1\/2-DIN chassis with illuminated front-panel controls and gold-plated RCA-level input connections. It includes a dedicated power, ground, and remote-turn-on connector, along with mounting brackets and mounting hardware. The design places the primary level, fader, input-selection, EQ, crossover, and illumination controls within reach for system adjustment.\u003c\/p\u003e\u003cp\u003eInstall the unit in a location with adequate clearance, such as under the dash or in a compatible dash opening, and test connections before final mounting. Connect it to a constant or switched +12V source using the provided 1-amp inline fuse, a clean chassis ground, and a source-unit remote or antenna lead. Use its line-level inputs with compatible source equipment and route front, rear, and subwoofer outputs to the corresponding amplifier inputs.\u003c\/p\u003e","brand":"Hifonics","offers":[{"title":"Default Title","offer_id":45631922733126,"sku":"HFEQ-2","price":92.0,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0048\/4163\/5910\/files\/61tkL3rEvsL.jpg?v=1784389450","url":"https:\/\/audiowatt.store\/products\/hifonics-hfeq-2-4-band-1-2-din-equalizer-crossover","provider":"Audio Watt Store","version":"1.0","type":"link"}
