AutoEQ

The AutoEQ is a tool for quickly and accurately undoing the EQ from

a factory head unit and achieving a at frequency response to the

DM-608/DM-810 outputs.

1. To use AutoEQ, connect a pink noise source to the factory head

unit (you can download a pink noise le from www.audiocontrol.

com).

2. Conrm signal presence with the Output RTA, and engage the

AUTO button.

3. After analyzing the incoming frequency spectrum, the software

will propose a new EQ curve. You can either accept the proposed

EQ curve or reject it. If you reject it, the proposed EQ curve the EQ

will go back to the setting before the AUTO button was engaged.

AutoEQ Hints

a. The AutoEQ analyzes the signal before the output MUTE, so if you

don’t want to listen to pink noise you can run the AutoEQ with all

of the outputs muted.

b. The AutoEQ only focuses on one output section at a time, so that

adjustments to the Front EQ do not interfere with adjustments to

the Rear or Center EQs.

c. The AutoEQ further renes adjustments with multiple passes, so if

the factory head unit requires major EQ changes you can run the

AutoEQ again one or two times to allow the DSP to make major

changes on the rst pass, then successively more delicate changes

to the EQ curve to approach a ruler-at response.

d. Again, you can reject any changes that the AutoEQ proposes on

any pass. This is so that if something unexpected happens during

the AutoEQ process, such as reaching the end of the Pink Noise

track, you can take a step back and repeat. You are the pilot in

charge, not a passenger on this journey.

e. At least a few of the RTA bands need to be over the 0 line for

proper, valid, and meaningful calculations.

f. Dad says..If your car heater stops working in cold weather, and

you would rather be toasty and warm, you might try checking the

water level in your radiator (when it is cooled), in case it has run

too low. (A cold heater is one of the rst signs of low water level.)

Then you can enjoy your AutoEQ more.
