The volume won’t go to the specified +10 dB maximum level.
The speaker output level settings may affect the maximum volume
level of the MV-5 Processor. The maximum volume level is +10 dB
minus the maximum output level setting of any speaker. Thus, if
your front L/R output levels are set to +3 dB, the maxium allowable
volume level is +10 dB minus +3 dB, or +7 dB.
The MV-5 is exhibiting erratic behavior.
1. Set the rear-panel power switch to the OFF position. Wait 10
seconds. Then set the rear-panel power switch to the ON
position.
2. Document all user-defined settings on the Installation Worksheet
that begins on page D-2. Then, follow the instructions on the
next page to restore factory default settings.
No audio appears to be output from the MV-5.
• Verify that all rear panel input & output connections are
correct.
• Verify that the Input Setup is set to the correct rear panel input
connections.
• Verify that the incoming datastream is compatible with the
input chosen.
Note: The input connectors marked S/PDIF INPUTS (RCA & TOSLINK
connectors) are not compatible with MP3 sources.
The 2-line OSD display does not appear on the video monitor.
• Verify that the 2-line OSD parameter under the Setup -> Display
Setup -> On-Screen Display menu is not set to OFF.
• Verify the video input source. The 2-line OSD is supported only
at 480i and 576i resolutions when the incoming video source is
digital.
VIDEO IN is set to NONE, but the monitor has a video error, or
is showing a blue screen.
When the VIDEO IN parameter is set to NONE, the MV-5 outputs a
blue screen in 480i resolution. This blue screen cannot be disabled.
If the monitor does not support 480i resolution, the monitor may
display an error message.
Note: This condition can also exist when the VIDEO IN parameter
has been setup, but there is no active incoming signal.
The Subwoofer(s) distorts frequently.
The likely cause for the subwoofer(s) to distort is either an
incorrectly set output level or the subwoofer high-pass filter is set
too low. Verify that the Sub/LFE LPF setting (subwoofer cross-over
point) is set correctly. If correct, try setting the SUB HPF setting to a
higher value to resolve the issue. Refer to Section 3: Setup for more
information.
Both the 2-ch Stereo and 2-ch Stereo Bypass listening modes
pass audio to the subwoofer. What’s the difference?
Both listening modes turn off all surround processing, except for
bass management to the subwoofer, to present pure left- and right-
channel stereo programs. However, the 2-ch Stereo Bypass mode
does not allow any user modification of the audio, such as Tone
Control adjustments.
Note: The 2-ch Stereo Bypass mode is only available when the Tone
Controls are set to OFF.
