Cloud VTX-WM1 Web Monitor Card, Surveillance Option For VTX Series Amplifiers, The VTX-WM1 Web Monitor Card is a retrofittable option for Clouds new VTX power amplifiers. It allows the amplifiers performance and settings to be monitored at a remote location using any computer (or PDA, smartphone, etc.), via a standard Internet browser. No dedicated software application or PC hardware is necessary.

The card plugs into a reserved slot on the amplifiers rear panel, and is fitted with an RJ45 Ethernet interface using regular network protocols. The data rate used is very low, which allows the buildings existing IT infrastructure to be used instead of a dedicated network. Amplifiers are simply connected into the IT system at the nearest convenient point. Where multiple amplifiers are co-located (e.g., in a rack), an Ethernet switch, with the appropriate number of ports, may be used to facilitate connection.

The web browser GUI is simple and intuitive, and the data clearly presented. A set of tabbed pages is displayed, which report the details and performance of all the amplifiers on the network. Parameters monitored include: network connection status, the settings of all amplifier rear panel switches and gain controls, protection circuitry activity, internal temperature, power status and input signal level for each channel. Fan operation and RL-1 remote volume control setting (if fitted) are also confirmed.

A load impedance test is available to check the integrity of each channels loudspeaker(s) and cabling. This test may be run either manually (i.e., initiated from the GUI as required), or automatically at pre-determined times and intervals usually during periods of non-occupancy. The frequency used for the impedance test is also programmable.

A password protected Housekeeping page is provided which allows site-wide details of the installation to be entered. This page also allows the load impedance test parameters, IP addresses and other system settings to be configured.

A real-time clock runs independently of the amplifier power supply, and an event log is maintained, which can be inspected as required for investigative purposes in the event of system problems. The system can also be configured to generate an email report if the WM1 detects a fault condition. The report may be formatted as SMS text if required. (This assumes that the necessary Internet connection and email/mobile accounts are available.)
