AudioControl EQS - Black (Open Box)

For over two decades, AudioControl has been designing and manufacturing award-winning autosound products at our factory located in the rainforests of the Pacific Northwest. During this period, countless sound-off winning contestants have chosen AudioControl products to give them the competitive edge. "Can you really win without AudioControl", was part of an article written commenting on competition winning systems. Nothing sounds better than an awesome recording played back on a kickbutt system. Unfortunately, the acoustics of your vehicle can take away from your systems performance. While AudioControl products do not change the laws of physics (although they act like they do), autosound enthusiasts have long known that AudioControl products "make good stereo sound better"

Great sound for six channels, all in one unit. Separate inputs and equalization for front, rear, and subwoofer speakers. The EQS has seven bands of full and half octave equalization control for the front and rear plus six, one-third octave equalization bands for maximum bass control. Add to that the Programmable Frequency Match (PFM) filter and a low output impedance line driver and you get maximum output and sonic clarity everywhere in the car. And to easily use a factory head unit, the EQS has built-in speaker level inputs. Truly a product for those who consider perfection possible.

Key Features:

Dual Bandwidth Equalization:

The EQS has 40 bands of AudioControl's award winning dual bandwidth equalization for total sound control. With the EQS, you have six, one-third octave equalization controls for the subwoofer plus seven, full and half octave equalization controls for both the front and rear channels.

Separate Front, Rear, and Subwoofer Inputs:

The EQS has six channels of input and six channels of output to provide a simple interface with today's multi-channel systems. By combining the sonic performance of AudioControl processing with the bells and whistles of a multi-channel head unit, you get maximum performance - using only one component. In addition, a unique switching system actually senses if connections are present at the subwoofer inputs of the EQS. If only four channels are being used, the EQS switches the subwoofer equalization automatically to the rear channels.

Maximize Your Bass Performance:

Optimum output of your performance sound system requires every component and speaker operating in an ideal environment. The AudioControl PFM (programmable frequency match) circuit gets the maximum output from your low frequency speakers and protects them from non-musical subsonic information. This programmable subsonic filter provides an 18 dB/octave high pass filter for your subwoofer or other low frequency speakers. The PFM is the ultimate tool for tuning subwoofer enclosures.

High Voltage, Low Impedance Line Driver:

Like other AudioControl products, the EQS has a 13-volt, low output impedance pre-amp line driver. This means the EQS can dramatically increase the pre-amp signal level from your source unit and deliver it downstream to the amplifiers. Higher signal voltage means maximum output, sonic clarity, and the ability to drive multiple amplifiers!

Easy Interface with Factory Installed Systems:

The EQS lets you easily add aftermarket amplifiers to factory installed source units via a built-in 4-channel active speaker level input adapter. Different than most speaker level adapters, there is no loss in fidelity when using AudioControl's design. In addition you can even continue to use your fader.
