Troubleshooting & Maintenance
Lexicon
5-6
3. If a DVD is loaded, the disc might have a copy-protection signal
(1-6) that prevents it from generating 96kHz signals. When a
copy-protection signal is present, the RT-10 automatically
downsamples signals to 48kHz before passing them to the
associated component, even if the Linear PCM parameter
(3-13) is set to Down Sample Off.
A humming sound is present in the audio.
1. If a cable TV connection is present, disconnect the cable from
the wall outlet. If this eliminates the humming sound, an
isolation device is required. Contact the cable provider for
assistance.
2. Disconnect components one at a time to isolate the problem.
Once the problem is identified, make sure the component is
properly grounded and connected to the same electrical circuit
as the RT-10.
Dialog sounds muffled.
1. If the RT-10 has a stereo audio output connection, set the Audio
Out parameter (3-16) to 2 Channel.
2. If the speaker setup does not include a center speaker, make
sure a center speaker is not selected with the component that
was used to configure speaker settings.
•
If the RT-10 was used to configure speaker settings, make
sure the Speaker Size screen C parameter (3-22) is set to
Off.
•
If the MC-12 or MC-8 Digital Controller was used to
configure speaker settings, make sure the CUSTOM SETUP
menu CENTER parameter is set to NONE.
Audio Output Issues
(continued from page 5-5)
The RT-10 is powered on, but there is no multi-channel
audio.
1. Set the Audio Out parameter (3-16) to 5.1 Channel. When this
parameter is set to 2 Channel, the RT-10 passes 2-channel
audio output to the associated component. Dolby Digital, DTS,
and MPEG sources are downmixed to two channels, allowing
playback of all audio channels recorded on the disc.
2. Make sure multi-channel audio is available on the loaded disc.
Multi-channel audio is only available for DVD-As and SACDs, as
well as other discs that include Dolby Digital, DTS, or MPEG
encoding. Other discs always output 2-channel audio, even
when the Audio Out parameter (3-16) is set to 5.1 Channel.
3. Make sure an audio track recorded in multi-channel format is
selected on the loaded disc (4-7). The remote control AUDIO
button or the disc menu can be used to select the desired
audio track (audio language and output format).
The RT-10 automatically downsamples digital audio sources
with high sample rates.
1. Set the Linear PCM Out parameter (3-13) to Down Sample Off.
When this parameter is set to Down Sample On, the RT-10
automatically downsamples 96kHz PCM signals to 48kHz
before passing them to the associated component.
2. If the loaded disc generates 192 or 176.4kHz signals, the RT-10
automatically downsamples these signals to 96 or 88.2kHz
before passing them to the associated component. The RT-10
will not pass 192 or 176.4kHz signals, even when the Linear
PCM parameter (3-13) is set to Down Sample Off.
