RV-8
CHECKING MICROPHONES
Appears in the on-screen display while
the RV-8 confirms the microphone level
calculated during the silence check. To
do this, the RV-8 sends alternating
calibration noise signals to the front left
and right speakers. These signals are output between 55dB and
95dB, beginning with 55dB and increasing in 5dB increments
until the microphones detect the required level. If the signal
becomes too loud, press the
microphone check.
The RV-8 uses the calibration noise signal to eliminate micro-
phones that register the signal at a level that is too low or too
high. Then, the RV-8 determines the appropriate output level for
the calibration noise signal used during automatic calibration.
CHECK MICROPHONES Results
Appears in the on-screen display when the RV-8 is finished
checking the microphones. This display indicates the individual
check results for each microphone.
• An OK result indicates that the microphone passed the
microphone check.
• An ERROR result indicates that the microphone did not pass
the microphone check.

4. Press the and arrow buttons to highlight the desired micro-
phone parameter. The RV-8 refers to the microphones according
to the input connector to which the microphone is connected.
5. Press the arrow button to view more detailed results for the
selected microphone. A message similar to the one shown at the
bottom of the previous column opens in the on-screen display.
Refer to the table on the next page for information about all
possible microphone check messages.
Note the following:
• The RV-8 retains the calculated microphone level until the
SPEAKER SETUP menu is closed. Once this menu is closed,
another microphone check is required before automatic
calibration can be performed.
• Optional microphone kits that include two microphones are
available. Perform automatic calibration with two microphones
that have passed the microphone check.
However, the RV-8 will perform automatic calibration as long as
at least one microphone passes the microphone check. In this
circumstance, place the successfully checked microphone in the
primary listening position.
• If a microphone check was successful, do not disconnect the
microphones from the microphone input connectors. If the
microphones are disconnected, you should perform the micro-
phone check again before proceeding to automatic calibration.
