Our Product Research Team

At Crutchfield, you'll get detailed, accurate information that's hard to find elsewhere. That's because we have our own in-house Product Research team — they open the box, verify contents, check the owner's manual, and record dimensions, features and specs. We stay on top of new products and technologies to help people make informed choices.

Features

Dual Bandwidth Equalization: A total of 13 bands are available over two bandwidths, each band has separate dials for the left and right channels:

• Full Octave EQ: A 7-band full octave equalizer controls frequencies above the bass range; the center frequencies are 250 Hz, 500 Hz, 1 kHz, 2 kHz, 4 kHz, 8 kHz, and 16 kHz. The rotary knobs adjust the signal +/-12 dB. There's a notch at each knob's center position so it's easy to return to the flat setting.
• Half Octave EQ: A 6-band 1/2 octave equalizer controls the bass frequency range; the center frequencies are 31.5 Hz, 45 Hz, 63 Hz, 90 Hz, 125 kHz, and 180 kHz. The rotary knobs adjust the signal +/-12 dB. There's a notch at each knob's center position so it's easy to return to the flat setting.

Input Gain: The input gains for the left and right channels are set independently. The range is adjustable +/-18 dB to match the source output to the EQ input.

Output Level: The adjustable output levels allow you to increase the head unit's line voltage to the top of your amp's input range; up to 9.5 volts RMS/13 volts peak.

Balanced Inputs: Using the balanced differential input circuit cancels noise picked up in the transmission line between the EQX and the source unit.

Speaker Level Inputs: The speaker level inputs are compatible with most factory installed radios.

Terminal Blocks: The power/ground/remote terminal and the speaker level input terminals are removable; the wiring is attached to the block, then the block is plugged into the EQX. The terminal block will accommodate wire up to 12 gauge.

Crossover: The crossover point between the high-pass and low-pass outputs is 90 Hz and the crossover slope is 24 dB/octave. The crossover point is governed by a replaceable chip, so it can be modified.

Subsonic Filter: The subsonic filter crossover point is 33 Hz and the crossover slope is 18 dB/octave. The crossover point is governed by a replaceable chip, so it can be modified.

Bridging Output: The mono and inverted low-pass outputs can be used to bridge many amplifiers that don't have internal bridging circuitry.

Bypass: The bypass switch allows you to instantly bypass all the EQ adjustments.
