Q-LAN Transmitter Component

Peak Output Level (dBFS)

Measures the Digital Signal level prior to the D/A converter.

Invert

Inverts the audio signal.

Mute

Mutes the digital audio signal.

Gain

Controls the gain of the digital audio signal prior to the D/A converter.

OK LED

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

Q-LAN Receiver 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.

NOTE:  These conditions are examples, and may not be applicable to all components with a Status field.

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.

Stream Name

The Stream Name identifies the connection between a Q‑LAN Transmitter, and a Q‑LAN Receiver. They must have the same Stream Name.

You can leave the Q‑LAN Receiver or Transmitter at the default setting, but at least one must be set to Dynamic Stream Name = yes in the Properties then rename the stream to match the other.

Primary OK

This LED indicates if the Primary Stream is OK or not.

Backup OK

If your Core is redundant, you can choose to have your Q‑LAN receiver / transmitter redundant.

This LED indicates if the Backup Stream is OK or not.

Network Rx Buffer

Adds extra buffer time to the default maximum of 1 ms.

Additional Network Receive Buffer time is useful in (rare) cases where the network latency through the network exceeds the default maximum. Additional network latency my be introduced by sub-optimal QoS functionality, some layer-3 routing implementations, long distances or large networks.

Details

(LAN A / LAN B)

Text indicating the Details of the transmitter stream. The information in this field is updated regularly and is cumulative. The information is displayed as running totals. Below is an example of some of the possible data.

• Enabled
• Connected
• Packet Count
• Timestamp

Reset Details

(LAN-A / LAN-B)

This is a momentary button that resets the networking details to zero, at which point the details start accumulating information again.

Name

User-defined name given to the Transmitter. This must be the same name as the Q-LAN Receiver to which the transmitter sends 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.

Location

User-defined name that groups the receiver with other components in the same physical location, or in the same organizational scheme.

Channel Count

Number of channels for the Transmitter. This must match the Receiver.

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.
