AudioControl EQX 13 Band Equalizer, 2-way Crossover and Line Driver

Maximum control

AudioControl's EQX graphic equalizer will make your music sound awesome in your car. Each channel on this versatile stereo equalizer features 13 bands of adjustment for sonic fine-tuning, along with level controls that allow you to match any receiver to any amplifier. The EQX's 2-way crossover offers a pair of high-passed outputs for your full-range speakers, two pairs of low-passed outputs for subwoofers, and a pair of full-range outputs for expanding your system even further with additional amps and speakers.

Crossover network

The crossover uses a steep 24 dB per octave slope to cleanly separate the high and low frequencies. You can change the preset 90 Hz crossover point by installing another AudioControl module, or by modifying the module installed in your EQX. A built-in filter removes subsonics from your signal so your amps and subs will play more efficiently.

Equalization bands

Most car audio problems occur in the bass frequencies, so the EQX gives you six bands of equalization between 31.5 and 180 Hz. You also get seven bands of equalization at octave intervals from 250 Hz all the way up to 16,000 Hz.

Level matching for max performance

Speaker-level inputs let you connect the EQX to just about any car stereo, even to factory amps that put out up to 100 watts. Once connected, the EQX makes it simple — turn up the input gain knobs until the maximized light comes on, adjust the output knobs until the output level lights up, and you're all set. Balanced inputs reject noises that are sometimes caused by a vehicle's electrical system.
