Speaker Setup
Jl-3. Level Calibration sub-menu Q
Here you will set the volume for each speaker so that they are all
heard by the lislener 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 selfings performed
above are vital to create the proper acoustics required for the
oplimum sound space and dynamics.
Notes:
• Be aware that when you enter this sub menu, a loud white
noise is output.
• 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-460M remote controller.

Calibrating the speaker levels
(l)When this sub-menu is entered, the TX-DS797 will emit a pink
noise from the front left speaker. At Ihis time, the Masler volume
aummalically increases to the reference level (0dB)_ Remember
the level of this noise and then press the • cursor button. (Note
that this can be adjusted to any level between -12 and 12
decibels in l-decibel intervals.) The TX-DS797 will now emit
the pink noise from the center speaken
(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 TX-DS797 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 adjusled 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 meier 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.
