16-Channel AES3 In
The AES3 16-channel Input in Q-SYS Designer has one input component associated component that you can add to your design. The AES3 Card gives you a total of 16 inputs of AES3 digital audio.
You can also use the AES3 inputs to sync Q-SYS to an external clock source. Refer to the Core Status topic for details. The AES3-1 option displays in the Core's Properties under Clock Source when you have an 16 Channel AES3 card selected for the Core I/O slot. Use this option to sync to an external AES3 signal. The AES3 selections require either regular AES3 or AES3 black.
Note: Typically, Internal is used as the clock source. Only if there is a need to synchronize the Q-SYS system to an external clock would you use GPIO or AES3. You would use GPIO if the external clock signal is a word clock. You would use AES3 if the external clock signal is an AES3 signal. Often an AES3 signal without audio is used to reduce the clock jitter. This signal is called AES3 black.
Type 2 Hardware 
Type 2 hardware provides new cables and connectors between the I/O cards and main boards in Cores and I/O Frames. Due to this change, the Type 2 hardware is not physically compatible with the older hardware. You can still integrate the new I/O Frames and Cores in the same system with older hardware, but the I/O cards are not interchangeable. Type 2 hardware can be identified by a yellow label on the back of the Core and I/O Frame, and the bottom of the I/O cards.
Properties
Core Properties
Name
The Name may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', and the hyphen. Names cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted.
Note: This name must match the Hostname for the device as defined in Core Manager or Peripheral Manager.
Location
User-defined name that groups the component with other components in the same physical location – for example, "Rack 1" – or in the same organizational scheme.
Is Network Redundant
Indicates if the amplifier is connected to redundant networks.
Slot A-H
When the AES In component is selected in the Schematic, you will see all of the Properties of the Core or I/O Frame in which it is installed. The only Property for the AES3 In component is Sample Rate Conversion.
SRC Disabled
Determines if the SRC (Sample Rate Conversion) is done by the AES3 In card or not.
Clocking
Sample Rate
Selects the sample rate. Typically, 48kHz is used as the Sample Rate. In scenarios where Q-SYS is externally synchronized to a (video) house sync signal you would use 48kHz Pull Down as the Sample Rate.
Clock Source
The GPIO selection requires an external TTL level word clock or a GPS connection: pin 1 is signal, ground in is indicated by the ground symbol on either end of the connector. When you select GPIO In Pin 1 as the clock source, GPIO Pin 1 is no longer displayed. The clock source should be connected to pin 1 of the GPIO connector.
Controls
AES3 In
AES3
Lock
LED indicating that the card is receiving a valid AES input signal.
Peak Input Level (dBFS)
Indicates if the signal is good (Green), close to clipping (Yellow), or clipping (Red).
Clip
Indicates if the signal is good (Green), close to clipping (Yellow), or clipping (Red).
Clip Hold
Holds the clip indication until manually cleared.
Digital
Invert
Inverts the input signal.
Mute
Mutes the input signal.
Gain (dB)
Sets the gain of the input signal.
Status
Component status is conveyed with the Status LED and Status box, which uses both color and text to indicate the current condition:
- OK: The device is functioning normally.
- Initializing: The device is in the process of a firmware or configuration update, or the design is starting.
- Compromised: The device is functioning, but a non-fatal problem exists. Refer to the Status box for details.
- Missing: The device cannot be discovered.
- Fault: The device is malfunctioning or is not properly configured. Refer to the Status box for details.
- Unknown: This status appears during a Core reboot (for example, during a firmware update), or when a design is being uploaded to the Core and before it has started running.
- Not Present: If applicable to the device, this status appears when the device is not connected to the network and its Is Required component property is set to 'No'. This status also appears if the device component's Dynamically Paired property is set to 'Yes', pairing has not been assigned in Core Manager, and the device component's Is Required property is set to 'Yes'. See Dynamic Pairing.
