The Axient Spectrum Manager is a powerful tool for calculating, analyzing and assigning compatible frequencies to wireless components. The Spectrum Manager scans the RF environment and uses this data to calculate compatible frequencies for all wireless channels found on the network. Networked wireless systems can be programmed from the Compatible Frequency List, while backup frequencies are continuously monitored and ranked according to quality. During operation, the Spectrum Manager deploys clear frequencies to receivers when interference occurs. Built-in spectrum monitoring tools provide visual and audio tracking of RF activity.
The Spectrum Manager captures scan data for the entire UHF frequency range available for wireless audio. The scan is compiled using two antenna inputs, with sensitivity and resolution that are directly applicable to wireless receivers.
The Compatible Frequency List (CFL) is list of available frequencies that can be calculated, viewed, and edited from the Spectrum Manager or it can be generated from a computer running Wireless Workbench® 6. The on-board frequency calculator can be adjusted to avoid specific TV channels, frequency ranges or RF signal above a specified threshold. During operation the Spectrum Manager provides current status of each frequency in the list. Clear frequencies are deployed from the compatible frequency list to initially setup a system or to replace frequencies degraded by interference.
The Event Log records actions of the Spectrum Manager during operation. Actions include changes to frequencies and equipment controlled by the Spectrum Manager. Reviewing the event log after a performance provides a snapshot of system performance.
The data screen tracks the status of all frequencies available for Axient systems. The number of frequencies is displayed for each band, including real-time status of in-use and backup frequencies.
The scanning feature of the Spectrum Manager graphically plots the measured RF signal across the full frequency range. Cursor, Zoom, and Peak tools allow detailed inspection of the data.
Use the Listen feature to tune to a frequency and monitor FM demodulated signal using headphones. The data screen displays the signal strength for the selected frequency.
Networking enables many of the advanced features of the Axient system, including monitoring and control of remote devices. Rack components have two RJ45 Ethernet ports capable of 10/100 Mbps network speeds. The Ethernet ports are power over Ethernet (PoE) enabled to supply power to the ShowLink™ access point or other class 1 Ethernet devices.
The cascade ports allow sharing of RF signal with up to 5 components without antenna splitters or distribution amplifiers.

The Spectrum Manager uses an Ethernet connection to deploy frequencies to networked components. For automatic network configuration, use a DHCP enabled Ethernet switch such as the AXT620 or an Ethernet router with DHCP service. Use multiple Ethernet switches to extend the network for larger installations.
Note: For smaller systems, connect the Spectrum Manager and receivers using the Ethernet ports on the back panel. The devices fall back to compatible addresses if the IP Mode is set to Automatic and there is no DHCP server.
Reset your device to restore factory settings.
Use only one DHCP server per network
All devices must share the same subnet mask
All devices must have the same level of firmware revision installed
Look for the network icons on the display of each device:
Use the Find All utility () to view devices on the network:
To check connectivity of WWB6 to the network:
Access to Shure networked components can be controlled by setting a network PIN from Shure control software. Once a PIN has been set, the correct password must be entered from the software to make changes to component parameters.
Use the following steps to clear a network PIN:
Tip: Performing a Reset All will clear a network PIN; however, all parameters will return to factory settings.
The Spectrum Manager includes a wizard to provide guided device and frequency configuration. Choose one of the following setup task options:
Use the All New option for initial RF coordination.
Use the Update Freqs option to refresh the frequencies for an existing wireless system.
Use the Update Devices option when adding new devices to a wireless system.
The following example shows the steps for initial RF coordination using the All New wizard option. Use the Update Freqs or Update Devices wizard options to coordinate an existing wireless system.
The RF plot is displayed in the data window. Press Next.
Most RF environments contain frequencies where it is not desirable to operate wireless equipment, such as those reserved for local broadcasts, public safety, or other users. Exclusions can be entered into the Spectrum Manager to prevent it from including these frequencies in its calculation of a compatible frequency list.
In this example, TV channel 32, the range of 599.00 to 604.000 MHz, and 650.000 MHz will be excluded from the compatible frequency calculation.
The event log records the actions of the Spectrum Manager and other devices it manages, as listed below. The log stores up to 150 events. The start of an event record is indicated with an asterisk (*). The most recent events appear at the top of the log. Use the control wheel to scroll through the list of events. When the storage limit is reached, the oldest events are overwritten.
Note: A power cycle or firmware update will clear the event log.
Compatible Frequency List (CFL):
The Spectrum Manager has built-in tools to provide an excellent resource for examining, tracking, and troubleshooting the RF spectrum.
During operation, the data screen tracks the status of frequencies available for Axient channels in the system. The total number of frequencies available for each band are displayed, including real-time status of in-use and backup frequencies. Backup frequencies which have been degraded by the monitoring function are removed from the count of Ready frequencies.
Use this feature to monitor the FM demodulated signal at a selected frequency.
Performing a spectrum scan creates a plot of RF activity on the data display. Use the Cursor, Zoom, and Peak tools to examine a specific area of the plot. The Store option allows for 2 plots of scan data to be saved by the Spectrum Manager for reference or for CFL calculation. Scans initiated from the Spectrum manager menu cover the entire tuning range. The Frequency Plot tool in Wireless Workbench software can be used to scan a subset of this range and provides options for step size and resolution bandwidth.
The RF plot is shown on the Data Display screen.
Cursor adds a movable vertical dashed line placed on the RF plot. Use the control wheel to position the Cursor at any point in the plot.
The frequency value and signal strength for the selected point are displayed at the top of the plot.
Zoom magnifies RF plot to allow for detailed analysis of a portion of the spectrum.
Use Zoom to identify individual frequencies in crowded RF environments.
Peak enables the cursor to only select the highest peaks of the RF plot.
Peak provides a quick way to identify the strongest signals in the RF plot.
The cooling fan has the following speed options:
Note: Speed may switch from Low to High if additional cooling is needed to protect the component.
Firmware is embedded software in each component that controls functionality. Periodically, new versions of firmware are developed to incorporate additional features and enhancements. To take advantage of design improvements, new versions of the firmware can be uploaded and installed using the Firmware Update Manager tool available in WWB6 software. Firmware is available for download from http://www.shure.com/wwb.
