AES Input
Purpose
AES Inputs provide entry points for a signal.
Note: Inputs devices may not be duplicated in a system. If two devices receive signals from the same input, both devices must be wired to the same input device either directly, through a Distribution Amplifier device or by using a Symbolic Node Transmitter and multiple Symbolic Node Receivers.
Controls
Channel Present
Indicates that audio data is present.
Level
Allows the input to be attenuated or boosted.
Note: Because of the head-room available in the digital domain, it is not possible to produce digital clipping even at extreme +12dB settings of this control.
Mute
Mutes the input.
Error
|
Not Present |
Board is not present in the system |
|
Receive Error |
Indicates if any error is present |
|
Not Locked |
No signal or signal is out of lock range |
|
Invalid Audio |
Audio Data received does not match AES format |
|
Poor Link |
Signal is noisy and/or has timing problems |
Clear Errors
Clears all error lights.
