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 
 nal test, choose the location 
that gives results closest to the 
average seen across all loca-
tions. This reduces the chance 
of choosing a poor location that 
happens to be in a room node.
