Manual Output Level Adjustment

Output levels may also be adjusted manually,
either to set them to a specific level with an SPL
meter, or to make fine tuning adjustments to the
levels obtained using the EzSet remote.
Manual output level adjustment is most easily
done through the

Navigation Button to select any channel
for adjustment using an external source, such as
a test disc, from which to judge the output levels.
After the ➔ cursor is pointing to the channel to
be adjusted, press the / Navigation Button
to raise or lower the output level. However,
before proceeding with any manual adjustment
we recommend that you first use the AVR's inter-
nal test tone generator and automatic sequencer
to send a tone to each channel so that you may
verify that all speaker connections have been
properly made.
To turn the test tone on and have it automatically
circulate among the channels where a speaker
has previously been configured (see page 24),

sound should be coming from.

and check the speaker wiring or connections to
external power amplifiers to make certain that
each speaker is connected to the correct output
terminal.
After checking for speaker placement, let the test
noise circulate again, and listen to see which
channels sound louder than the others. Using the
front left speaker as a reference, press the
Buttons on the remote to bring all speakers
to the same volume level. When one of the
buttons is pushed, the test noise circulation will
pause on the channel being adjusted to give you
time to make the adjustment. When you release
the button, the circulation will resume after five
seconds. The on-screen cursor and the test
