Q-LAN Transmitter Component

VIDEO TUTORIAL: Video tutorial available online for Core to Core Streaming.

The Q-LAN Transmitter, in combination with the Q-LAN Receiver, provides audio streaming between Cores on the same LAN.

You must set both Cores' Clock Domains to Custom in the Core Properties in order to stream audio between Cores. If the domains are not set to Custom, and you attempt to run the design, an error message is displayed indicating that the clock is not set correctly.

Controls

Control	Function	Default/Range
Peak Output Level (dBFS)	Measures the Digital Signal level prior to the D/A converter.	Green = good Yellow = close to clipping Red = clipping
Invert	Inverts the audio signal.	Off/On
Mute	Mutes the digital audio signal.	Off/On
Gain	Controls the gain of the digital audio signal prior to the D/A converter.	Default = 21 Range = -10 to +21
Stream Name	In the Emulate or Run mode, you can enter a name for the transmitter stream. When the design is running, another design with a Q-LAN Receiver can see a list of available Transmitters with Stream Names assigned. You can select the one you wish. To use the Stream Name, you must set Dynamic Stream Name to Yes in the Transmitter's Properties.	User Defined
Q-LAN Transmitter Status	Displays the current status of the Transmitter both in text and color. The following is a list of possible status colors, and some example conditions. OK – Green – (0) – Audio is good, hardware is good. Compromised – Orange – (1) – Audio is good but a redundancy mechanism is active (one LAN down but the other is still up) or a non-fatal hardware problem exists (fans too slow, temperature higher than expected, etc.) Fault – Red – (2) – Audio is not passing, or hardware is malfunctioning or mis-configured (amplifier power off, audio streams broken, wrong type of I/O Card installed, loudspeaker short circuit, etc.) Missing – Red – (3) – A piece of hardware, defined in the design, has not been discovered. Audio is not passing through that piece of hardware. Initializing – Blue – (5) – In the process of firmware, configuration update, and design start. Audio is obviously bad. Not Present – Gray – A virtual component in the design, that is designated as Dynamically Paired, and Not Required ,has no hardware assigned to it.	N/A
Tx OK	LED indicating the status of the Transmitter network link for both LAN A and LAN B (If network redundant).	N/A
Details	Text indicating the Details of the status of the Transmitter. The information in this field is updated regularly and is cumulative. The following information is displayed as running totals.	N/A
Reset Details	Available only when Verbose is set to Yes in the Transmitter Properties. This is a momentary button that resets the networking details to zero, at which point the details start accumulating information again.	N/A

Q-LAN Transmitter Status

Displays the current status of the Transmitter both in text and color. The following is a list of possible status colors, and some example conditions.

OK – Green – (0) – Audio is good, hardware is good.

Compromised – Orange – (1) – Audio is good but a redundancy mechanism is active (one LAN down but the other is still up) or a non-fatal hardware problem exists (fans too slow, temperature higher than expected, etc.)

Fault – Red – (2) – Audio is not passing, or hardware is malfunctioning or mis-configured (amplifier power off, audio streams broken, wrong type of I/O Card installed, loudspeaker short circuit, etc.)

Missing – Red – (3) – A piece of hardware, defined in the design, has not been discovered. Audio is not passing through that piece of hardware.

Initializing – Blue – (5) – In the process of firmware, configuration update, and design start. Audio is obviously bad.

Not Present – Gray – A virtual component in the design, that is designated as Dynamically Paired, and Not Required ,has no hardware assigned to it.

Properties

Property	Function	Choices
Name	User-defined name given to the Transmitter. This must be the same name as the Q-LAN Transmitter from which the Receiver gets the audio transmission. You cannot have duplicate Q-LAN Transmitter Names on the same network. The Name may contain ASCII letters 'a' through 'z' (case-insensitive), the digits '0' through '9', the hyphen, and the underscore. Names cannot begin or end with a hyphen. No other symbols, punctuation characters, or blank spaces are permitted.	User-defined
Location	User-defined name that groups the receiver with other components in the same physical location, or in the same organizational scheme.	User-defined
Channel Count	Number of channels for the Transmitter. This must match the Receiver.	1 to 16
Is Redundant	Is the Core on which the Q-SYS design containing the Transmitter using both LAN A and LAN B connections? This selection adds the Control Pins LAN A OK, and LAN B OK.	Yes / No
Dynamic Stream Name	Enables the Stream Name field in the Control Panel.	Yes / No
Verbose	Provides status details in the Transmitter's Control Panel. This selection adds the Control Pins Details and Reset.	Yes / No
