Q: I can't route audio

One of the most common issue with routing audio is switch/router/firewall blocking/filtering out multicast traffic required for the PTP protocol. Please disable IGMP snooping and disable any multicast blocking/filtering. Consult your switch/router/firewall manual.

Q: What do I do about feedback?

Reduce the gain setting in the Q-SYS or amplifier system.

Q: I can't connect to a V-Page

The default network state of the unit is DHCP. A set of IP addresses are needed were each address can be assigned via a network switch that will handle IP address automatically or the use of third-party application like BootIP where the user can assign an IP address manually based on the MAC address of the network interface.

Each V-Page unit has two MAC addresses one for control and the other for digital audio. Our unique ID start as 00:10:46:XX:XX:XX where Audinate unique ID start as 00:1D:C1:XX:XX:XX.

It’s important to clarify QSC Q-SYS Core based systems and V-Page control IP must be allocated under the same network and subnet.

Q: Can't connect to V-Page/buttons unresponsive/Q-SYS component shows offline

This answer applies to any issues related to Q-SYS V-Page communication. Any of the following could be the case:

V-Page isn’t properly configured (Incorrect IP and/or subnet, or incorrect router input set)
V-Page Q-SYS IP reference or remote port doesn’t match the network setup
There’s a firewall preventing broadcast traffic from getting through to the V-Page
Configured IPs (Q-SYS, V-Page) are on a different subnet

Q: Firmware Failsafe Recovery Mode

This mode should only be entered when the V-Page is on a test bench and is not wired into the rest of the network.

To enter Failsafe Recovery Mode, start with your V-Page powered off. Set the Dip Switch #2 to ON (down), then power on your unit, then return Dip Switch #2 to OFF (up) position. The V-Page is now placed on a static control IP of 192.168.0.254, regardless of its settings. Then, update firmware like normal by opening a web browser and going to https://192.168.0.254, and follow the prompts. When the V-Page comes back online, it will no longer be at 192.168.0.254, but instead at the last remembered control IP address. If you don’t know what that was, feel free to flip dip switch number 2 to on then off again while powered up to reset the unit to factory defaults.

Q: Can I adjust my PTPV2 V-Page clocking priorities?

You cannot adjust this setting on our V-Coms or V-Pages, but don't fret. Our priority settings fall in the middle of the PTPv2 priority spectrum, meaning if you have a different product such as a Q-SYS Core, you can set that product be the grand master based upon its adjustable priority settings compared to the static V-Page/V-Com priority settings.

Our AES67 enabled V-Page and V-Com products (VPage-VP4X, VPage-VP16K, VCom-VC12X, and VCom-VC16K) PTPv2 clocking priorities are set and are not changeable. They are:

Priority 1: 249
Priority 2: 112

NOTE: They must sit on domain 0 (DFLT .129).

To ensure our V-Page or V-Com products are not chosen as a master clock in your system, you must set a different product that you'd like to be the master on your network to domain 0 and Priority1 to 0 (or just ensure that it is any number below 249). The lower the number, the higher the priority per the BMC Algorithm.

NOTE: AES67 requires PTPv2, which is not backwards compatible with PTPv1 (which Dante uses).

Best Master Clock (BMC) Algorithm Details

In a PTPv2 network, one clock is elected as the Grandmaster. The Grandmaster is the clock from which all other clocks will derive their time. The Grandmaster is selected using a process that involves the BMC - or Best Master Clock algorithm. This algorithm takes into account the following information, prioritized in this order:

Priority 1: the user can assign a specific static-designed priority to each clock, preemptively defining a priority among them. Smaller numeric values indicate higher priority. From 0 - 255. Lowest number wins.
Class: each clock is a member of a given class, each class getting its own priority.
Accuracy: precision between clock and UTC, in nanoseconds (ns)
Variance: variability of the clock
Priority: final-defined priority, defining backup order in case the other criteria were not sufficient. Smaller numeric values indicate higher priority. From 0 - 255. Lowest number wins.
Unique identifier: MAC address-based selection is used as a tiebreaker when all other properties are equal. For more details on this subject, check out this wikipedia article.

Q: How can I make my Q-SYS Core the PTPv2 Grandmaster?

By default, the Q-SYS Core's Priority settings are set to the following:

PTP Priority 1: 254
PTP Priority 2: 100

By comparison, our V-Page/V-Com Priority 1 is set to 249.

This means that if the settings are not adjusted in Q-SYS Designer, our V-Page or V-Com units will always win the algorithm, and your Q-SYS Core will never become the Grandmmaster. To change this, all you must do are adjust these settings in QSYS Designer. Go to File > Design Properties.

Here, you can manually adjust the Priority 1 and Priority 2 settings. Again, you'll want to set Priority 1 to something less than 249. You will also want to make sure that your QoS settings on your network match the settings here, otherwise you could experience audio problems and dropped packets. For more information about PTPv2 and Clocking Prioirities in the QSC ecosystem, check out this article.

You can see whom is the PTPv2 Grandmaster in Dante Controller, in the Clock Status tab. Look in the AES67 column for this information. Just note, Dante Controller only lists products that your computer can see on the network.

If you're seeing a V-Page or V-Com product that is still not relinquishing a master status, it's possible that what you're seeing is a V-Page that didn't have AES67 enabled and, therefore, is operating via Dante using PTPv1. It won't release it's master if there's no other device on the network operating in PTPv1. Please confirm that all V-Pages and V-Com units have AES67 enabled so they will all operate on PTPv2 protocol.

Q: Locating a V-Page on a Network

The V-Page hardware contains one physical Ethernet connection but two isolated interfaces (V-Page control and Dante audio). This means there are 2 MAC addresses assigned to each V-Page. Further, on any given network there are most likely multiple V-Pages.

This guide focuses on simplifying locating process of the physical V-Page unit remotely using V-Page station ID, V-Page MAC/IP (control), Dante MAC/IP (audio) and control <-> audio interface matching in a physical V-Page unit. All units must be online (both interfaces) on the same subnet.

AMI Terminal, one of our free pieces of software available for download on our website, is used to send all the commands. AMI Terminal can broadcast across your subnet by connecting to X.X.X.255, i.e. 192.168.0.255. AMI Terminal cannot connect to a Dante audio interface, but it can match by the Dante information stored in the V-Page, hence it can be used to match any given Dante interface information to the physical V-Page including physical identify by the Dante MAC/IP address.
