1-3. Level Calibration sub-menu
Here you will set the volume for each speaker so that
they are all 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 above are vital to create the proper
acoustics required for the optimum sound space and
dynamics.
Note:
The speaker level settings here are not effective for
multi-channel input sources. To adjust the speaker lev-
els for multi-channel input sources, you will need to use
the CH SEL, LEVEL+, and LEVEL- buttons on the RC-418M
remote controller. See page 53.

Calibrating the speaker levels
(1) When this sub-menu is entered, the DTR-9.1 will emit
a pink noise from the front left speaker. At this time,
the master volume automatically increases to the
reference level (0dB). Remember the level of this
noise and then press the DOWN cursor button.
(Note that this can be adjusted to any level be-
tween -12 and 12 decibels in 0.5-decibel intervals.)
The DTR-9.1 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
the same level as 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 DTR-9.1 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 recom-
mended 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.
