Taramp's TEQ 7.4 Pro 7-Band Car Graphic Equalizer

The Taramps TEQ 7.4 Pro is a compact 7-band car stereo graphic equalizer and preamp that gives precise tonal control, adjustable subwoofer level with LPF and multiple RCA I/O for custom system tuning.

This low-profile EQ is designed to sit in a car audio chain between head unit and amplifiers, giving you seven frequency bands (50Hz to 12kHz) with +/-12 dB adjustment, master and auxiliary input level control, and dedicated subwoofer volume with an adjustable low-pass filter (40–250 Hz). Built for installers and enthusiasts, the TEQ 7.4 Pro delivers clean signal path specs — very low distortion, wide frequency response and high signal-to-noise — while the blue panel lighting makes it easy to view settings at night.

How does the TEQ 7.4 Pro improve sound quality in a vehicle?

By letting you correct frequency imbalances and tailor the tonal curve to your speakers, cabin and preferences. The seven bands target the most relevant ranges for bass, midrange and highs so you can remove boom, fill in presence or tame brightness.

• Seven adjustable bands: 50, 125, 315, 750, 2.2k, 6k and 12kHz for targeted tuning.
• Band range: variable up to +/-12 dB for subtle or strong correction.
• Low overall distortion (0.0001) and wide response (6 Hz–55 kHz) preserve detail.

What connections and controls does it provide for system integration?

The TEQ 7.4 Pro has stereo RCA inputs (main + aux) and three stereo RCA outputs for front, rear and subwoofer lines, plus independent input gain and master level controls to match signal sources and amplifiers.

• Inputs: 2 stereo main, 2 stereo auxiliary for flexible routing.
• Outputs: front, rear and subwoofer stereo RCAs to feed separate amps.
• Level controls: master and aux gain adjustment; output impedance ~100 ohms.

How is the subwoofer handled and tuned?

A dedicated subwoofer level knob with an adjustable Low-Pass Filter gives you precise control over bass roll-off and level so the sub blends with mids and highs without overpowering the cabin.

• Subwoofer volume control for balance between sub and full-range speakers.
• LPF adjustable from 40 Hz to 250 Hz to set crossover point to taste.
• Maximum output level up to 28.28 Vpp (10 Vrms) for strong preamp drive.

What are the physical and electrical specs I should know?

Designed to install under a dash or in a compact rack, the TEQ 7.4 Pro runs on typical car voltages and draws minimal current while offering professional-level performance figures.

• Dimensions: 185 x 31 x 138 mm (compact footprint for tight installations).
• Operating voltage: 9–15 VDC; nominal consumption ~0.27 A at 12.6 V.
• Performance: >100 dB S/N ratio, >80 dB channel separation at 1 kHz.

Who is this for? The Taramps TEQ 7.4 Pro is aimed at car audio enthusiasts, installers and anyone upgrading a factory or aftermarket system who wants precise EQ control, reliable preamp outputs and an adjustable sub crossover without bulky processing gear. It’s ideal when you need compact hardware that delivers professional tuning options, clean audio performance and simple RCA connectivity for multi-amp systems.
