Editing the P.EQ menus

You can compensate for the frequency charac- teristics using the basic P.EQ according to your car type.

•The P.EQ adjustment contents are as follows:

Channel selection

Select the channel to be compensated (front or rear).

Selection of center frequency

Select the center frequency that you want to compensate from the range of 20Hz to 20kHz. (1/3 octave step, 31 points)

Selection of Q-curve

Set the sharpness of the Q-curve to one of the parameters: 1, 3, 5, 7 and 20.

Gain adjustment

Adjust the gain (output level) in the range of - 12dB to +12dB. (1dB step, 25 points)

About the compensation of frequency char- acteristics

See Figure 1 concerning the relationship of the center frequency, Q-curve (Q) and gain.

About the Q-curve (Q)

For the Q-curve (Q), setting larger values makes the curve sharper, setting smaller values makes the curve flatter. (Figure 2)

Selecting the Q-curve (Q) opposite to the fre- quency curve to be compensated makes the fre- quency characteristics flat.
