Failed microphone/SPL meter test
During the microphone/SPL meter test details are displayed in the
following dialogue box:
The pass/fail status of the microphone measurement is based on
the Power and SNR (signal to noise ratio) values. In most rooms
and with most SPL meters Power will usually be in the range –25
to –35, and SNR will usually be in the range 44 to 60. The larger
the SNR the better the measurement.
The following sections describe some of the most likely problems
which will cause the Power and SNR values to go outside these
ranges.
Power less than –44
The following error will be displayed:
This indicates that there is very little or no signal on the connector
you have chosen as your microphone input. Check the following:
• That there was sound from the front left speaker during the test.
If in doubt, repeat the microphone/SPL meter test. If there is still no
sound check the connections from the digital surround controller to
the left loudspeaker. Switch the digital surround controller off and
then on again, select
Calibrate
as described in the
G68 Digital
Surround Controller Installation Guide, and check that the left
speaker plays the calibrate signal.
