Spectrum Manager
General Description
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.
Features
Wideband Scanning
The Spectrum Manager captures scan data for the entire UHF frequency range available for wireless audio. The scan is com
piled using two antenna inputs, with sensitivity and resolution that are directly applicable to wireless receivers.
Compatible Frequency List
The Compatible Frequency List (CFL) is list of available frequencies that can be calculated, viewed, and edited from the Spec
trum 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.
Event Log
The Event Log records actions of the Spectrum Manager during operation. Actions include changes to frequencies and equip
ment controlled by the Spectrum Manager. Reviewing the event log after a performance provides a snapshot of system perfor
mance.
Backup Frequency Monitoring
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.
RF Scanning
The scanning feature of the Spectrum Manager graphically plots the measured RF signal across the full frequency range. Cur
sor, Zoom, and Peak tools allow detailed inspection of the data.
Listen
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.

Note: For smaller systems, connect the Spectrum Manager and receivers using the Ethernet ports on the back panel. The devices fall back to compatible ad
dresses if the IP Mode is set to Automatic and there is no DHCP server.
Automatic IP Addressing
If using a Shure AXT620 Ethernet switch, set the DHCP switch to ON.
Set the IP mode to automatic for all devices (Util > Network > Mode > Automatic)
Manual IP Addressing
Connect the Spectrum Manager and receivers to an Ethernet switch.
Set the IP Mode to Manual for all devices:
Menu: Util > Network
Use the control wheel to set valid IP addresses for all devices. Set the subnet mask for all devices to the same val
ue.

If the LEDs are not on and the cable is plugged in, replace the cable and recheck the LEDs and network icon.
Use the Find All utility (Util > Network > Find All) to view devices on the network:
The Find All report lists all devices on the network.
Check the IP address for devices not shown in the Find All report to ensure that they are on the same subnet.
To check connectivity of WWB6 to the network:
Start WWB6 software and use Inventory view to see devices connected to the network.
If not, find the IP address from one of the devices on the network (such as an AXT400 receiver) and see if you can ping
it from the computer running WWB6.
From a WINDOWS/MAC command prompt, type "ping IPADDRESS" of the device (e.g. "ping 192.168.1.100").
If the ping returns success (no packet loss), then the computer can see the device on the network. If the ping returns
failure (100% packet loss), then check the IP address of the computer to ensure it’s on the same subnet as the device.
If the pings are successful and the devices still do not show up in the WWB6 inventory, check to ensure all firewalls are
either disabled or allow the WWB network traffic to pass to the application. Check that firewall settings are not blocking
network access.
Network Access Control
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:
From the home screen: Util > Network > Access.
Use the control wheel to select Disabled.
Press enter to save.
Tip: Performing a Reset All will clear a network PIN; however, all parameters will return to factory settings.
