EXTERNAL NOISE TEST
Selecting the LEVELS CALIBRATION menu EXTERNAL NOISE TEST
option opens the SPEAKER LEVEL ADJUST menu shown on page 3-55,
which manually calibrates output levels.
The external noise test requires an external calibration source such as
an audio calibration disc. When the external noise test is conducted,
the RV-8 activates a listening mode based on the current Main Zone
input source. Refer to the table below for more information about
external noise test listening mode activation.
When a listening mode is activated during the external noise test, all
custom listening mode menu parameter settings are ignored. The
listening mode is applied to the current Main Zone input source in its
factory-default condition. When the external noise test is finished, the
listening mode returns to its custom condition.

* These listening modes depend on the speaker configuration. Dolby Pro Logic IIx MOVIE
will only load when side and rear speakers are present.
**These listening mode names differ depending on the current input source, speaker
setup and parameter settings. Refer to the Listening Mode Descriptions section
beginning on page 6-4 for more information.
**If the Advanced Menu input is set to “ANALOG BYPASS OFF” the listening mode for the
EXTERNAL NOISE TEST is “5.1a STANDARD”.
Note:
When the external noise test begins, the RV-8 automatically sets
volume level to +0dB. Avoid adjusting the master volume level while
the test is in progress, to achieve THX reference levels (75dB).
To manually calibrate output levels during the external noise test:
1. Set the SPL meter to “C” weighting and “SLOW” response.
2. Place the SPL meter at the primary listening position.
3. Press the or arrow button to highlight the output level
parameter you want. Then press the button to select this
output level parameter.
The horizontal bar graph shown on page 3-55 is displayed.
4. Begin playback of the external calibration source and press the
or arrow button to select the output level that achieves a 75dB
SPL Meter reading.
5. After selecting the output level, press the arrow button to close
the horizontal bar graph.
6. Repeat steps 3, 4 and 5 until you have set all the output levels you
want.
