Customizing the Nº502 Mark Levinson
menu. Refer to the “Speakers” section found earlier in this chapter for
more detail.
Audio In
The Audio In menu associates the specific Nº502 rear panel audio input
connector(s) to be used for the current Activity. Selecting the Audio In
menu option displays the list of audio input connectors available on the
rear panel. Select one of the available connectors to associate it with this
Activity.
Audio Profile
The Audio Profile menu associates the Audio Profile that is loaded by the
Nº502 for the current Activity. Selecting the Audio Profile option displays
the list of existing Audio Profiles. Select one to associate with this Activity.
If a new Audio Profile is needed for this Activity, then back out of the
Activities menu and select the Audio Profiles option from the main Setup
menu. Refer to the “Audio Profiles” section found earlier in this chapter
for more detail.
Stereo Analog In
Level
The Stereo Analog In(put) Level parameter adjusts the 2-channel stereo
analog audio input levels. Since analog audio sources can have a wide
range of input levels, the Nº502 allows the input levels to be
independently adjusted for each Activity through the Analog In Level
parameter.
Selecting the Stereo Analog In Level parameter opens an adjustment bar,
with an available range of –18.0dB to +12.0dB in 0.5dB increments.
Main Audio Delay
The Main Audio Delay parameter delays the audio signal until the sound
and picture are synchronized. This parameter should only need
adjustment if the audio and video become out of sync. This can happen if
the system uses any kind of post-processing on the video source, which
tends to add a small delay to the video output. Adjusting the Main Audio
Delay parameter on the Nº502 delays the audio signal to compensate for
any inherited video output delay, for each individual Activity.
Selecting this parameter opens an adjustment bar, with a range of 0.0ms
to 500.0ms in 0.5ms increments.
HDMI Audio
Output Options
This parameter identifies the format of the HDMI audio output signal.
The available selections include:
• Encoded – the native format of the incoming signal is output. If the
receiving device does not recognize the native format, the Nº502
prompts a change to the audio output format.
• PCM – the incoming signal is converted to a downmixed PCM format
before it is output.
• Off – turns off the audio output entirely. If Off is selected, then NO
audio is output from the HDMI rear panel output connectors.
