|Adjusts input level to match audio signal source.
MIC: For microphones or mic-level outputs
LINE: For line-level outputs.
MIC W/ PAD: Applies a 17 dB pad for additional attenuation when needed for high output microphones.
Note: For the best signal-to-noise performance, the pad should only be used when the MIC setting does not provide enough attenuation before clipping.
|Adjusts audio input to the transmitter.|

To lock the transmitter, select.
To unlock the transmitter:
An on-screen key appears showing the joystick sequence to unlock the transmitter.
Use this to turn on the transmitter without transmitting RF. This allows you to change frequency settings on the transmitter without accidentally interfering with a frequency being used by another transmitter.
The home screen displays RF OFF.
Use this shortcut to power on the transmitter with the interface locked. This prevents accidental changes to transmitter settings.
The home screen displays the lock icon.
The transmitter holds up to 10 microphone presets. Use this menu to access a list, add, delete presets, or to copy and paste a preset list. Use the list submenu to set, modify or delete selected presets.
Note: The UR3 is shipped with an empty preset list.
Access the preset menu:
|Enters the LIST submenu.|
|Add a new preset.|
|Deletes all presets.|
|Copy and paste the entire preset list to another UR3.|
Access the preset list:
Use the list submenu to set, modify, or delete presets.
|Activates the selected preset.|
|Modify the selected preset.|
|Deletes the selected preset.|
To change or modify the presets, you must enter the microphone preset submenu:and select a preset. From the sub-menu you can set, modify, or delete the setting.
Use the joystick to edit values:
ENTER: move to the next value.
UP/DOWN: edit the selected value.
EXIT: exit the preset.
To exit and save: Continue to scroll right, through all fields, until PRESET SAVED appears.
To edit the eight-character name:
Use COPY/PASTE to transfer the mic preset list from one plug-on transmitter to another. This function can be used between different transmitter frequency bands.
Important: COPY/PASTE must be highlighted on both transmitters.
