Q-LAN Receiver Component

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

The Q-LAN Receiver, in combination with the Q-LAN Core to Core Transmitter, 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 Input Level (dBFS)	Meters for each channel indicating the peak analog input level. The measurement is taken after the A/D converter, but before the Digital Gain. Use this meter in conjunction with the Max Input Level to obtain an input signal as close to 0 dBFS as possible without actually clipping.	Default = N/A Range = -100 to 20
Invert	Toggle button to invert the digital output of the Mic/Line input card.	Off/On
Mute	Mutes the output signal.	Off/On
Gain (dB)	Controls the Gain of the digital output signal.	Default = 0 Range = -100 to 20
Q-LAN Receiver Status	Displays the current status of the Receiver 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
Rx OK	LED indicating the status of the Receiver network link for both LAN A and LAN B (If network redundant).	N/A
Details	Text indicating the Details of the status of the Receiver. The information in this field is updated regularly and is cumulative. The following information is displayed as running totals:
Reset Details	Available only when Verbose is set to Yes in the Receiver Properties. This is a momentary button that resets the networking details to zero, at which point the details start accumulating information again.

Default/Range

Peak Input Level

(dBFS)

Meters for each channel indicating the peak analog input level. The measurement is taken after the A/D converter, but before the Digital Gain. Use this meter in conjunction with the Max Input Level to obtain an input signal as close to 0 dBFS as possible without actually clipping.

Default = N/A

Range = -100 to 20

Invert

Toggle button to invert the digital output of the Mic/Line input card.

Off/On

Mute

Mutes the output signal.

Off/On

Gain

(dB)

Controls the Gain of the digital output signal.

Default = 0

Range = -100 to 20

Q-LAN Receiver Status

Displays the current status of the Receiver 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

Rx OK

LED indicating the status of the Receiver network link for both LAN A and LAN B (If network redundant).

N/A

Details

Text indicating the Details of the status of the Receiver. The information in this field is updated regularly and is cumulative. The following information is displayed as running totals:

Reset Details

Available only when Verbose is set to Yes in the Receiver Properties. This is a momentary button that resets the networking details to zero, at which point the details start accumulating information again.

Properties

Property	Function	Choices
Name	User-defined name given to the Receiver. 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 Receiver 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 Receiver. This count must match that of the Transmitter.	1 to 16
Is Redundant	Is the Core on which the Q-SYS design containing the Receiver 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 Receiver's Control Panel. This selection adds the Control Pins Details and Reset.	Yes / No
