Audiotek AT-EQ700 5-Band Car Audio Equalizer

The Audiotek AT-EQ700 is a car-audio graphic equalizer designed to give a compatible aftermarket sound system more direct tonal control. Its five-band adjustment section lets listeners shape the overall balance of bass, midrange, and treble to better suit their vehicle, speakers, and music. It is intended for systems using RCA-level audio connections.

This equalizer is a practical option for drivers who want more tuning flexibility than the basic tone controls on many source units. Each equalization band provides boost or cut adjustment from -12 dB to +12 dB, allowing measured corrections rather than broad, fixed presets. The separate master volume control supports convenient system-level adjustment from the equalizer.

A selectable-frequency low-pass filter and adjustable subwoofer volume help integrate a subwoofer channel into the rest of the system. This makes it easier to tailor low-frequency output independently from the front and rear channels. The design is suited to systems using external amplification and RCA signal routing.

The AT-EQ700 includes three stereo RCA outputs, supporting multi-channel signal distribution in a car-audio setup. An auxiliary stereo RCA input adds a wired source connection, while the input selector allows switching between available inputs. Front-to-rear fader control provides a straightforward way to balance the main listening area.

For an upgrade path, the equalizer can be placed between a compatible source unit and external amplifiers. It adds hands-on level, fader, subwoofer, and tonal controls without replacing the vehicle's existing audio source. An LED power indicator provides visible confirmation of operating status.

Design & Installation

The AT-EQ700 uses a control-focused layout with dedicated equalizer, master-volume, fader, and subwoofer-level adjustments. Its confirmed product information also includes an LED power on/off display. Housing materials, finish details, and physical dimensions are not specified in the available product data.

Install the equalizer in a location that provides access to its controls and allows safe routing of power, ground, input, and output wiring. Use compatible stereo RCA cables for the auxiliary input and the three stereo RCA outputs, then connect the outputs to the appropriate downstream audio components. Set equalizer and subwoofer levels conservatively during initial setup to match the connected source unit and amplifiers.
