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.
