Audiocontrol EQS

Item(s) Description/Condition:

8/10 because unit is used. No obvious scratches, works flawlessly

The EQS is a 6-channel equalizer/line driver. There are are dedicated 7-band graphic equalizers for the front and rear outputs, and a 6-band graphic equalizer for the subwoofer output.

Dual Bandwidth Equalization: A total of 13 bands are available over two bandwidths:

Front/Rear EQ: Two 7-band equalizers feed the front and rear outputs; the center frequencies of both are 120 Hz, 160 Hz, 250 Hz, 500 Hz, 1 kHz, 2 kHz, and 10 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.

Subwoofer EQ: A 6-band 1/3 octave equalizer feeds the subwoofer outputs; the center frequencies are 31.5 Hz, 40 Hz, 50 Hz, 63 Hz, 80 kHz, and 100 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.

Line Driver: To achieve the best possible signal to noise ratio and dynamic range from your amplifier, the built-in line driver can increase the head unit's output voltage up to 18 dB (9.5 volts RMS/13 volts peak).

Input Gain: The input gains for the front, rear, and sub channels are set independently. The range is adjustable +/-12 dB to match the source output to the EQ input.

Output Level: The +20 dB maximum output level allows 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 EQS the the source unit.

Ground Isolation: The power supply ground is switchable, in case of ground loop noise. The factory position is fully isolated (typically the best choice), but can be changed to Ground or 200Ω.

Auto Select Inputs: The EQS automatically switches the inputs to maximize the equalization controls, whether you use two, four, or six preamp inputs.

Speaker Level Inputs: The 4-channel speaker level inputs are compatible with most factory installed radios, even most Bose systems.

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 EQS. The terminal block will accommodate wire up to 12 gauge.

Subsonic Filter: The subsonic filter crossover point is 33 Hz. The crossover point is governed by a replaceable chip, so it can be modified.

Go to DIYMA some people there are willing to remote tune it for you for a small fee. Usually around 30-50 dollars.
