The Gravity EQ15 is a compact 1/2 DIN car audio graphic equalizer designed to place detailed sound adjustment and system-level control within easy reach. Its five EQ bands are centered at 50Hz, 125Hz, 900Hz, 2. 2kHz, and 16kHz, allowing users to tune low-end impact, reduce midrange harshness, enhance vocal presence, and refine treble detail for their vehicle’s speakers and amplifiers. An active gain preamp with adjustable input sensitivity helps match the EQ15 to a compatible head unit or audio source. The unit delivers up to 9V RMS maximum output through three stereo RCA output pairs for front, rear, and subwoofer amplifier connections. A dedicated master volume control provides convenient adjustment of overall listening level directly from the dash or console. The built-in AUX/DVD input selector supports easy switching between connected sources, making the EQ15 suitable for car audio builds and mobile theater systems. Technical specifications include an 11,15V DC negative-ground power requirement, 10K ohm input impedance, 90 dB signal-to-noise ratio, 0. 05% THD, 82 dB channel separation at 1kHz, and 10Hz,50kHz frequency response at -3dB. The subwoofer frequency range is 10Hz,300Hz for flexible bass-system integration.
