RV-8
Internal Noise Test
(continued from page 3-42)
Note:
The RV-8 automatically sets the volume level to +0dB
when the internal noise test begins. It is recommended
that you avoid adjusting master volume level while
the test is in progress to achieve a 75dB THX refer-
ence level (a 75dB SPL meter reading).
When the internal noise test is conducted, a calibration test signal
travels to the Main Zone speaker and audio output connectors in
the order listed on the SPEAKER LEVEL ADJUST menu. As the cali-
bration test signal travels, the cursor automatically scrolls down-
ward through SPEAKER LEVEL ADJUST menu parameters, high-
lighting each speaker parameter as the corresponding output
connector is tested. Each output connector is tested for about 4
seconds.
The SPEAKER LEVEL ADJUST menu can be used to manually adjust
output levels while the internal noise test is conducted.
To manually adjust output levels while the internal noise test is
conducted:
1. Set the SPL meter to "C" weighting and "SLOW" response.
2. Press the remote control Menu
the desired SPEAKER LEVEL ADJUST menu parameter.
3. When the desired parameter is highlighted, quickly press the
Menu arrow to select this parameter. A horizontal bar graph
will open in the on-screen display.
4. When the horizontal bar graph opens, follow the instructions
on page 2-16 to adjust the selected parameter. All output levels
should be adjusted to achieve a 75dB SPL meter reading from
and arrows to highlight
the primary listening position.
5. When you have made the desired adjustments, press the Menu
arrow to close the horizontal bar graph and return to the
SPEAKER LEVEL ADJUST menu. The internal noise test will
continue, and automatic scrolling will resume.
Please note the following:
When the internal noise test is conducted, it is possible to select a
SPEAKER LEVEL ADJUST menu parameter just as the RV-8 is about to
automatically scroll to the next parameter, causing the RV-8 to send
the calibration noise to both speakers. If this occurs, reselect the
desired speaker.
Note:
Main Zone speaker/audio output connectors for
which the corresponding CUSTOM or THX SETUP
menu parameter is set to NONE cannot be adjusted
during the internal noise test. These connectors can
be adjusted during the external noise test, but there
is no need to do so.
