1-3. Level Calibration Sub-menu
Use this sub-menu to set the volume for each speaker so that each
volume is heard by the listener at the same level. This is especially
important for speaker layouts where the left and right speakers are at
different distances or in asymmetrical positions due to room designs
and configurations. These settings and the distance settings
performed in the Speaker Distance Sub-menu are vital to create the
proper sound space and dynamics.
Note:
The speaker level settings here are not effective for multi-channel
input sources. To adjust the speaker levels for multi-channel input
sources, you will need to use the CH SEL, LEVEL   , and LEVEL
 buttons on the RC-511M remote controller. See page 34.
Calibrating the speaker levels
(1) When this sub-menu is entered, the TX-NR900/900E will emit a
pink noise from the front left speaker. At this time, the volume of
the pink noise will automatically increase to a predetermined
reference level (0dB). Remember the volume level of this noise
and then press the   cursor button. (Note that this can be
adjusted in 1-decibel increments.) The TX-NR900/900E will
now emit the pink noise from the center speaker.
(2) Using the   and   cursor buttons, adjust the volume level of the
noise from the center speaker so that it is at the same level as that
was emitted from the front left speaker. You can jog back and
forth between the speakers to help you compare the volume
levels.
(3) Press the   cursor button again. The TX-NR900/900E will now
emit the pink noise from the front right speaker.
(4) Repeat steps (2) and (3) above for the front right and other
speakers until all speakers are adjusted to the same volume level.
Notes:
• Speakers that you selected “No” or “None” for in the Speaker
Config Sub-menu will not appear.
• To accurately set the output levels, it is recommended to use a
handheld sound pressure level (SPL) meter. Set the meter to C-
weighting and slow averaging. A Radio Shack
®
 SPL meter or
equivalent is recommended. Using the internal channel noise
generators, set each channel so that you read a 75 decibel sound
pressure level.

Using the remote controller
1. Press the TEST button.
You will hear a pink noise will be emitted
from the front left speaker.
(1) Remember the volume level of this noise
and then press the CH SEL button. The TX-
NR900/900E will now emit the pink noise
from the center speaker.
(2) Using the LEVEL  /  buttons, adjust the
volume level of the noise from the center
speaker so that it is at the same level as that
that was emitted from the front left speaker.
(3) Press the CH SEL button again. The TX-NR900/900E will now
emit the pink noise from the front right speaker.
Use the LEVEL  /  buttons to adjust the volume of the noise
from the front left speaker so that it is the same level as that that
was emitted from the center speaker. The pink noise level can be
adjusted in 1-decibel increments.
(4) Use the CH SEL button to select other speakers and adjust the
volumes until all speakers are adjusted to the same level.
2. Press the TEST button to complete
the procedure.
