Detection Sensitivity - Shure AXIENT AXT400 Mode D'emploi

Interference Detection
Interference Detection analyzes the RF signal for signs of interference that can degrade the audio signal. When interference is detected, the receiver screen turns red and
displays one of the following warning messages:
Interference Alert
Displayed on the home screen when low-level interference is detected. Interference at this level may not be audible or may only cause a slight disruption to the audio signal.
All receiver controls can still be accessed, and If the interference is not audible, a frequency change may not be necessary.
If Interference Avoidance is set to Auto mode, a frequency change will not occur unless the strength of the interference increases to trigger an Interference Detected
message.
Interference Detected
Displayed when high-level interference likely to disrupt the audio signal is detected. The home screen is replaced with on-screen options for changing to a clear frequency or
if Interference Avoidance mode is set to Auto, the channel will automatically switch to a clear frequency deployed by the Spectrum Manager.
If the Interference clears without being addressed or if a frequency change is made by the Spectrum Manager, the LCD screen will return to its normal color. The detection
message with an timer indicating time elapsed since the interference occurred will remain on the screen for up to 60 minutes or until dismissed.

Detection Sensitivity

The sensitivity setting allow you to vary the timing of warning messages to match the RF conditions and the need to avoid interference.
Normal
• Generates a message in response to low levels
of interference well below the audibility threshold
• Provides more time to react to messages
Setting up an Audio Channel
Setting the Frequency Band
Set to the Receiver to the same frequency band as the
transmitter.

Server
1. From the home menu screen, select Radio.
2. Press the control wheel to highlight Band.
3. Turn the control wheel to set the receiver band to
match the transmitter band.
4. Press the ENTER button to save.
Frequency Diversity
Frequency Diversity uses two independent radio frequencies sent from an AXT200 handheld transmitter or from two AXT100 bodypack transmitters connected with a "Y"
cable to deliver a single uninterrupted audio channel. To optimize performance, Frequency Diversity mode must match the transmitter type.
To set Frequency Diversity mode:
1. Menu: Options > Diversity
2. Turn the control wheel to select FD-Bodypack for AXT100 bodypack transmitters or to select FD-Handheld for AXT200 handheld transmitters.
More Sensitive
• Generates a message in response to low levels
of interference well below the audibility threshold
• Provides more time to react to messages
Linking a Transmitter using IR Sync
The IR Sync function forms a link between a transmit-
ter and the receiver and automatically sets the trans-
mitter frequency.

2. Align the transmitter with the IR port on the front
panel. The red IR sync LED on the receiver IR port

will illluminate to indicate correct alignment. Press

3. The display indicates if the IR sync is successful.
Check transmitter alignment and select Retry if a
failure occurs. The receiver passes an audio signal
if successful.

Less Sensitive
• Detects interference at a level just below the
audibility threshold
• Fewer detection messages
• Less time to react to messages
4. Linking a transmitter creates a persistent control re-
lationship with the receiver channel, enabling remote
control and synchronized frequency changes when
ShowLink is active.
• Up to 2 transmitters can be linked, which
allows alternate transmitters to be added to the
channel and remotely controlled.
• Turn the control wheel to select the transmitter
in slot 1 or slot 2 before pressing Sync.
5. When a transmitter is successfully linked, a confir-
mation is displayed and the link status icon appears
to the left of the channel name on the receiver home
menu. Link status is not maintained with UHF-R
series transmitters.
6. Transmitters can be unlinked from the channel,
clearing the link relationship.
• From the home screen menu, select Tx
• Turn the control wheel to select the device ID of
the transmitter to be unlinked
• Press the Unlink menu option or link another
transmitter to overwrite the selected link slot
