Automatic Setup Procedure

CHAPTER 5

The automatic setup procedure uses the microphone to measure and evaluate your system. After the measurements are complete, the levels, crossover frequency, and delay times of the speakers in your system are automatically adjusted for the best performance. Any problems with the speakers in your system are indicat- ed, for example, if there is no output from a speaker, or if the polarity is reversed.

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.With the remote control set to operate the TGR-401, press the MENU button to enter the OSD main menu. Use the remote's navigation buttons to reach the Auto Setup menu. The testing procedure will start when you press the right navi- gation button.

4.When the measurements are over, the results are displayed, and you have the option of rejecting or accepting them.

5.If you accept the results, the adjustments to the level, crossover frequency, and delay are saved and applied to your system.

• If some of the measurements

are labeled "bad," try moving

the microphone to a new posi-

tion about six inches away, and

repeat the auto setup.

• If the measurements indicate

that a speaker has reversed

polarity, check the speaker

cable connections and cor-

rect this problem. The positive

output of the TGR-401 must

connect to the positive input of

the loudspeaker, and the nega-

tive output must connect to the

negative input of the speaker.

• For larger rooms, or rooms

with multiple seating posi-

tions, it is best to repeat the

measurements several times,

with the microphone in differ-

ent positions within 6 inches

of each other. Write down the

results of each test, and for the

final test, choose the location

that gives results closest to the
