SCAN MENU
Frequency Scan
The frequency scan menu is where the URX50 will scan the user specified frequency range and search for a
clear frequencies. The frequency range that will be scanned will be displayed on the bottom half of the screen.
The frequency range that will be scanned is set and can be changed in the next menu.
After the scan is completed a graphic display of the RF that is present, in the specified range, will be shown.
The URX50 will also suggest a clear frequency. That frequency can be accepted by pressing the CH UP key. Or
press the CH DOWN key to skip the first chosen frequency and have the URX50 suggest another frequency.
Scanning for a frequency
• Turn off the transmitter(s).
• From the scan menu press the CH UP key to initiate a scan.
• While the URX50 is scanning, the frequency being examined is
displayed in the bottom half of the screen. Once the scan has
completed a graphic map of the scan will be displayed. The low end of the frequency range is on
the left side and the high end is on the right. Wherever RF is found, a vertical line will be drawn.
The line extends from the baseline up. The length of the line indicates the level or strength of the
found RF at that frequency.
Selecting the frequency
When the scan is complete the URX50 will draw a vertical blinking line
on the display to indicate where the first suggested frequency is, and
the frequency in MHz will appear below the scan graphic.
• Press the CH UP key to accept the new frequency.
• Press the CH DOWN key to decline and suggest a different frequency.

Headphone Router
When receiving a stereo signal, the headphone routing will which signal (Left, Right or Both) will be routed to
the headphones.
Speaker Enable
• ON - Turns on the speaker.
• OFF - Turns off the speaker.
Audio Delay Set
The audio delay menu is where a variable delay to the output audio is set. A delay is useful if the URX is being
used for personal monitoring and there is a video processing delay to the monitors - so engaging the delay will
delay the audio to match the video. The audio delay can be adjusted from 1MS to 400MS in 1MS increments.
Volume Mode
• Variable - The volume keys will function as normal
• Fixed - The volume keys will be disabled, and the audio output will be fixed at the current gain setting.
Extra Volume
Up to 10dB of digital gain and be added to the headphone output from this menu.

1KHZ Notch
When turned on the 1Kilohertz filter will notch out audio at the 1KHz frequency, this way if someone is
monitoring audio and a tone is sent the listener will not hear it.
Volume Beeps
• ON - There will be a beep tone in the headphone out when adjusting the headphone volume.
• OFF - The headphone volume beeps will be muted.
Mute If Unit Code
This menu sets if transmitters with certain ZaxNet unit codes will not be able to be monitored by the URX50.
For example, if this menu is set to 30 any transmitter with a ZaxNet unit code below 30 will not be able to be
monitored by the URX50.
If a muted preset is selected to be monitored “MUTE” will appear on the display and that preset will not be able
to be listened to - even if that preset is enabled.

SETUP MENU
Modulation Select
The modulation menu is where the receive format is set. Modulation is simply the way a transmitter
“modulates”, or sends, its signal to the URX50. This setting needs to match the modulation mode that the
corresponding transmitter is set to - if the two setting do not match the URX50 will not be able to receive and
decode the signal from the transmitter.
Modulation types
• MONO XR - Select when receiving audio from a transmitter sending mono, stereo or XR modulation.
• ZHD 96 - Select when receiving signal from a ZHD transmitter set to ZHD-96.
Unit Code
This is where the code is set to identify the URX. Each URX needs to have a unique identifier code so it can be
controlled by the remote GUI.
IFB Voting
The IFB voting feature will allow the URX50 to automatically switch to a secondary frequency when it loses its
signal from the primary transmitter. One purpose of this is, on a large set, a second transmitter can be placed at
a distant location, so if the URX50 loses the signal from one transmitter it will automatically switch to the other
transmitter.
To use IFB voting just set the offset in this menu. Then set the second transmitters frequency to the primary
frequency + the offset. So, for example if the primary frequency is 560.000 MHz and the offset is 200 KHz then
the second transmitter should be set to 560.200 MHz

Software Update
This is where the URX software is updated from.
When in this menu pressing the CH UP key will initiate the update process and the URX50 will wait and search
for software that will be transmitted from a Zaxcom transmitter (please refer to the software update section of
this manual for more information on how to update the URX).
Display Flip
The display flip menu changes the orientation of the display. Please note when the display is flipped the CH UP
and CH DOWN keys are flipped as well.
Battery Type
The battery chemistry that is being used in the URX50 is selected in this menu. Lithium, NIMH or Alkaline can be
selected.
Scan on boot
• ON - When the URX boots up it will look for and if necessary, scan for the data channel being sent from the
Zaxcom GUI Bridge via a Zaxcom TRXCL3 camera link transmitter.
When the URX boots up it will look for data from the TRXCL3’s on preset number 1 if the URX does not find
the data it will initiate a scan to search for the data.
For the URX to automatically find the data from the TRXCL3 the UNIT ID code on the camera link needs to be
set to 99 and transmit frequency needs to be set to a whole MHz frequency (for example any frequency like
550.00 MHz or 551.000 MHz will work - a frequency like 550.100 MHz will not work). Then after the data is
received the URX will automatically go back to the frequency it was originally set at.
• OFF - The URX will boot up as normal. If the data is present on the frequency it booted up to it will take the
data if no data is present the URX will continue to operate as normal.

The URX50 can be set to output a test tone from this menu. This is useful to set levels and check routing.
Pressing the INC and DEC key will cycle through the different tone settings.
• OFF - No tone is being outputted.
• -20dBFS -Tone is simultaneously sent to both outputs at -20dBFS.
• +0dBFS - Tone is simultaneously sent to both outputs at full scale 0dBFS.
Information Page
This page displays the current firmware version and the serial number of the URX50.
Encryption Code Set
This is where the encryption is turned on and the code is set. This code needs to match the encryption code of
the associated transmitter(s). If an encryption code is set on the transmitter the transmitted audio will be
encrypted and can only be listened to if the URX has the same matching encryption code entered. When the
codes do not match, all that will be heard is white noise.
These two sets of numbers are formed into a single six-digit encryption code which provides a total of
16,777,216 possible combinations. For non-encrypted operations, all six numbers should be set to 0.
