SWITCHING AUDIO INPUTS AUTOMATICALLY
RCM-28 remote amplifiers allow automatic switching from the AES feed to the analog input in the case of failure of the
AES signal or input. This feature allows a redundant analog signal to be fed to the amplifier and automatically switch
over to the „backup" signal without user intervention.
Open the Modify Properties dialog from the context menu of the RCM-28 remote amplifier in the IRIS-Net worksheet.
Following table lists the relevant properties for automatic audio input switching.
Property
Audio Input Switching. AES
Fail. Enable
Audio Input Switching. AES

Audio Input Switching. AES
Good. Enable

Default Range

kHz
Description
The labels of an amplifier and its input and output channels are shown in a clear
structure. All labels can be edited. Changes are immediately reflected in the different
panels and windows (amplifier control panel, flow diagram, and overview).
CAUTION: Using * (asterisk) and/or = (equal) signs in a name is not permissible.
Default Range
0 0, 1
1 s 0 to 120 s
0 0, 1
Description
Indicates if the digital audio input is synchronized to the input
signal (LOCKED LED on) or if synchronization was not
successful (ERROR-LED on).
HINT: The current state of the digital audio input is available
via the properties "State Flags. AES Locked" and "State Flags.
AES ERROR" also.
Shows the sample rate of the AES/EBU input signal.
Press the SET button if the audio input should switch from
digital input to analog input automatically if the digital input
signal is not OK.
The value of the property "Audio Input Switching. AES Fail.
Enable" corresponds to this control.
Description
Set the value to 1 to enable the auto fall back function
which switches from AES to analog input in case of an AES
error. This property corresponds to the „Auto Switch
Enable" control found in the Config & Info window.
Configures the duration the AES error had to be present on
the input to trigger the AES / analog switching.
Setting this property to 1 enables the automatic switching
from analog input to AES input in case the AES signal is
OK.
HINT: This works only if the values of both properties –
Audio Input Switching. AES Fail. Enable and Audio Input
Switching. AES Good. Enable – are set to 1.
