Mute/Active Button; Bn And Gn Offset - Shure ULXD6 User Manual

Mute/Active Button

The button is configured to toggle between Mute and Active. The following
options are available:
• Toggle: Press button to mute microphone, press again to pass audio
• Push-to-Talk: Hold button to pass audio
• Push-to-Mute: Hold button to mute microphone
• Disabled: Button functionality off
Change button behavior using Wireless Workbench or the receiver front
panel.
Menu path: IR PRESETS > GOOSENECK / BOUNDARY > MUTE BUTTON BEHAVIOR
Note: When the mute/active button is set to Disabled, the transmitter will
still send TPCI data if the button is pressed.
High-Pass Filter
Each transmitter contains a high-pass filter.
The high-pass filter:
• attenuates frequencies below 150 Hz by 12 dB per octave
• reduces low-frequency noise caused by table vibration or air handling
systems
Adjust high-pass filter settings using Wireless Workbench or the receiver
front panel.
Menu path: IR PRESETS > GOOSENECK / BOUNDARY > HIGH PASS
Transmitter RF Power
Reference the following table for setting RF Power:
RF Power System
Setting Range
1 mW 33 m (100 ft.)
10 mW 100 m (330 ft.)
20 mW >100 m (330 ft.)
Menu path: IR PRESETS > GOOSENECK / BOUNDARY > RF POWER
Note: Using the 20 mW setting decreases the transmitter battery runtime
and reduces the number of compatible systems.
Locking Transmitter Controls
Boundary and gooseneck base transmitters have a power lock to prevent
accidental or unauthorized changes to the transmitter. When the power
lock is on, the transmitter's power switch is disabled.
To unlock, use receiver front panel or Wireless Workbench.
Menu path: IR PRESETS > GOOSENECK / BOUNDARY > POWER LOCK
Attempting to access a locked feature will display the following message
on the receiver front panel:
Application
For increased channel reuse at close
distances
Typical setups
For hostile RF environments or
long-distance applications
Setting Initial State From Charger
Use the receiver front panel or Wireless Workbench to control a transmit-
ter's state after you remove it from a networked charging station.
• Active: On and passing audio
• Muted: On but the audio is muted
• Off: Power is off
Menu path: IR PRESETS > GOOSENECK / BOUNDARY >
INITIAL STATE FROM CHARGER
Note: If Mute Button Behavior is set to Push-to-Talk and
Initial State From Charger is set to Active, the transmitter will only
pass audio when you push the mute button. Make sure to coordinate
settings for Mute Button Behavior and Initial State From Charger.
Audio Signal Encryption
When encryption is enabled, the receiver generates a unique encryption
key which is shared with the transmitter during an IR sync. Transmitters
and receivers that share an encryption key form a protected audio path,
preventing unauthorized access from other receivers.
Enable encryption using Wireless Workbench or the receiver front panel.
For more details, see the user guide for your receiver.
Encrypting a Single Transmitter to a Single
Receiver
1. From the receiver menu: DEVICE UTILITIES
> ENCRYPTION > ON (Auto)
2. Press ENTER.
3. Perform an IR Sync to share the encryp-
tion key with the selected transmitter.
Removing Encryption
1. From the receiver menu: DEVICE UTILITIES > ENCRYPTION > OFF
2. Press ENTER.
3. IR Sync the transmitter and receiver to clear the encryption key.
Note: If multiple transmitters are encrypted to a single receiver, each
transmitter must be IR synced to clear the encryption key.

BN and GN OFFSET

BN OFFSET and GN OFFSET compensate for signal level differences between
transmitters that share the same receiver channel. For normal gain adjust-
ments, use the receiver gain buttons.
Set the offset gain on a low signal level transmitter to match a louder
transmitter: IR PRESETS > GOOSENECK / BOUNDARY > BN OFFSET
IR PRESETS > GOOSENECK / BOUNDARY > GN OFFSET
