Audiocontrol EQS preamplificatore equalizzatore 6 canali

AudioControl designed the EQS for one reason — to make your car audio system sound better. This rugged 6-channel equalizer features 13 bands of adjustment for sonic fine tuning, along with a line driver that allows you to send the cleanest possible signal to your amplifiers. And speaker-level inputs allow you to connect the EQS to just about any car stereo, even Bose® systems and factory amps up to 400 watts.

The EQS features inputs and outputs for your front, rear, and subwoofer channels, fitting between your receiver and your amplifiers in the signal chain. Once connected, the EQS makes it easy — turn up the input gain knobs, adjust the output knobs until the light indicates the desired output, and you're all set. You can adjust the output level up to 9.5 volts, so you can maximize the performance of any amplifier.

Most car audio problems occur in the bass frequencies, so the subwoofer channel gives you six bands of equalization between 31.5 and 100 Hz, along with a rolloff filter that keeps inaudible subsonic bass out of your subwoofer system. You also get seven bands of equalization from 120 Hz all the way up to 10,000 Hz on the front and rear channels. If you're not using the sub channel, the low-frequency EQ section switches to the rear channel automatically.

Balanced inputs reject noise caused by your vehicle's electrical system, but you have the option of grounding your inputs to solve ground loop problems.

The EQS is designed to work with a variety of systems, whether it's tied directly into a single amp or connected to an AudioControl crossover in a multi-amp setup. Check out the system diagrams in More Photos.
