CHAPTER 5

Auto EQ

The automatic EQ procedure uses

the microphone to measure and

evaluate your system. This takes into

account room effects, and automati-

cally flattens out the response. After

the measurements are complete, the

EQ of your system is adjusted. The

procedure does not use any previous-

ly measured information from the auto

setup, or user-entered information.
Warning: The test procedure can emit

LOUD test tones through your speak-

ers.

The procedure should be done in

a quiet environment, so only the test

tones will be picked up by the mi-

crophone. Use only the microphone

supplied.

1. Place the measurement micro-

phone on the back of your fa-

vorite listening couch or chair.

Try to place it at head height if

possible, in the position where

your head normally is while

listening to your home theater.

The microphone should point

straight up towards the ceiling,

so it has an omni-directional

response for highest accuracy.

2. Connect the microphone to the

Mic input behind the sliding

front panel of the TGR-401.

3. In the EQ menu, select Auto

EQ and the measurements will

begin. The test tones will be

played and the measurements

taken. The procedure takes ap-

proximately four minutes. The

EQ of each speaker pair will be

adjusted for the best response.

Auto EQ uses a complex DSP

analysis of your room to create

dynamic EQ filters. Therefore,

detailed results of this process

are not displayed.

Manual EQ adjustment

The EQ of your system can also

be adjusted manually, using your

ears and preferences instead of the

measurement microphone. There is

14 dB of cut and boost available at 11

frequencies, except for the subwoofer.

In the EQ menu, you can select

Manual EQ Global, or Manual EQ

Pairs.

"Manual EQ Global" allows you

to adjust the EQ of the combined

speaker system. Use the menu to

choose the frequencies and make the

adjustments with the remote, to suit

your preference.

"Manual EQ Pairs" allows you to

adjust the EQ of the front pair, center,

surround pair, surround back pair and

sub.
