• Audio Source: Select from AES1/2, MPX1/2, DMPX AES1/2 or Analog L/R.
NOTE
: The allowable range of audio source selections will vary depending on which audio input sources
are already occupied. For example, if a preset's main audio source is set to AES1 in Left Mono mode,
then the same preset's internal SCA1 source cannot be set to AES1 Left.
• Audio Mode: Applies to Analog Left/Right and AES1/2 sources only. Select Mono L, Mono R,
Mono L+R or Stereo (selecting Stereo applies a 19 kHz pilot).
• Analog Level: Applies to Analog Left/Right sources only. Enter value between -12 and +12 dBu,
which represents the input voltage level that yields 100% modulation (Default is 0.0 dBu).
• 15 kHz Lowpass: Applies to AES1/2 sources only sources only. Select Enabled (applies 15 kHz
low-pass filter to audio input) or Disabled.
