Welcome to our Troubleshooting FAQs page. Here, you'll find answers to common questions and solutions to issues you may encounter while configuring, operating and maintaining a HOLOPLOT sound system.
Why can't I access HOLOPLOT Control on my browser?
If you experience issues with loading HOLOPLOT Control on your laptop or desktop that is connected to the HOLOPLOT system, walk through these steps:
Ensure the controller is powered and booted (fan revving up when powered?)
Press the power button behind the front grill if not booted yet
Confirm the Gigabit 1 port is connected to the switch/router
Confirm the laptop is on the same network
Confirm the controller can be accessed by typing in the IP address directly in the browser (run IP scan if necessary to determine IP)
If the problem persists:
Confirm IDRAC port is connected in case HOLOPLOT remote support is needed.
Confirm the network has an internet connection in case remote support is needed.
What should I do if the interface of HOLOPLOT Control appears empty?
If you cannot see some or any Modules in HOLOPLOT Control, check these parts:
Make sure the module is powered on.
Ensure the module is connected to the dedicated network, carrying a switch and router (DHCP server) through the primary Uplink port.
See if the module appears in Dante Controller and check for IP range.
Configuring the system
What should be done if controllers cannot connect to the cloud due to a lack of NTP sync between controllers?
If you encounter issues with module status toggling between online/offline and your controllers cannot connect to the cloud due to a lack of NTP sync between controllers, follow these troubleshooting steps:
Check internet connection: Verify that your laptop has a wired internet connection.
Ping time servers: On your laptop, ping "time1.google.com" or "time.google.com" to ensure they are reachable.
Ensure Internet access: If any of the above points fail, ensure your setup has Internet access and is not blocked by firewall settings.
Check switch settings: Examine the switch settings to which Modules and controllers are connected. Confirm if IPv4 and/or IPv6 routing is disabled.
If routing is enabled, disable it on all relevant switches and restart all controllers.
Following these steps, you can troubleshoot and resolve issues related to module status toggling and cloud connection without NTP sync between controllers.
I have no sound coming from a specific module or array
If you have no sound coming from a specific module or array, walk through these steps to locate an issue:
Connection, hardware and 3rd party sofware components
Validate power to the module
MD96:
Validate power connector to the module and ensure rear display reads information.
MD 80-S
Validate Sub connections (Sublink Ethercon, Power EP and Power Sub Amplifier). Interconnections need to be established before booting the module otherwise it will come up as unset. If the module is in unset mode, proceed with next step.
Power cycle the sub
Confirm network connections by scanning/pinging the module's IP address
Check Dante Controller four routing and critical events
Check Dante Controller for audio input and output
Test network cables
HOLOPLOT configuration
Confirm a project is loaded and inputs assigned
Confirm health status (esp. temperature) & metering
Confirm overall system health
Check input metering
Check output metering, check Mute and Solo buttons
Validate signal path on per channel basis
Updating the system
What should I do if a module becomes stuck during an update?
If you experience an issue when updating a module where the update is stuck:
Make sure your network is still hooked up to the internet.
Health reporting of HOLOPLOT Controllers in redundant setups is currently incorrect.
HOLOPLOT Control

You need not take any action; we’re preparing a fix for an upcoming release (OS 2.1.0)
Metering stops when switching projects
The Metering may stop reacting when switching between projects in HOLOPLOT Control.
HOLOPLOT Control
2.0.6
Open
If metering stops working after switching between projects, close all open browsers connected to HOLOPLOT Control, wait 15 seconds, and reopen the page.
You need not take any action; we’re preparing a fix for an upcoming release (OS 2.1.0)
Routing persists when switching projects
The routing of a deactivated project is applied to another active project. This behavior might occur when two projects are loaded in HOLOPLOT Control created from the same HOLOPLOT Plan project, enabled by the "Save as…" option.
HOLOPLOT Control
2.0.6
Open
Rebooting the modules will clear the routing information of the previously active project.
The issue has been fixed in the upcoming release of OS 2.1.0
