Setup and Operation
Receiver Placing the receiver and connecting the antennas
Place the receiver on an even surface and connect the antennas provided to the
antenna jacks. Put the antennas upright in a Vshaped position.
- Place the receiver at least 1 meter above the ground and not too close to lateral walls.
- Avoid sources of interference such as metal surfaces or electronic devices (e.g. computer, CD player).
- Ideally, position the receiving antennas at the height of the transmitter. When using multiple systems, do not allow antennas to cross or touch each other.
- For optimum reception, keep the transmitter at least 1 meter away from the receiver and avoid obstacles.
- For rack installation (483 mm/19″), screw on the two mounting brackets provided at the left and right sides of the housing.
The antennas provided are suitable for use in good reception conditions. If more than one receiver is to be used, it may be better to use the R14D antenna distribution system and the R22AU directional antenna (accessories).
Connecting a mixer or amplifier
Connect the receiver to the following unit (e.g. mixer, amplifier).
- Set the input level of the following unit to minimum as long as the transmission path for the microphone system is not established.
- Use the balanced XLR output for connection to a balanced microphone input.
- Use the unbalanced 6.3 mm jack for connection to a line input via the connection cable provided.
- If the subsequent unit is provided with both connections, the XLR output should be used for an optimum signal transmission.
- Both outputs are connected in parallel allowing for audio output to two separate inputs.
- By operating the receiver with units grounded via the mains cable (e.g. amplifier, mixer), noise interference may occur due to ground loops. To eliminate this interference set the groundlift switch to position LIFT.
Connecting the power supply unit
Finally, connect the receiver to the mains via the power supply unit provided.
Thus the unit is powered on and is in standby mode. The power switch and the
display light up.
- Slide the country adapter onto the power supply unit and connect the cable to the power input jack of the receiver. Pass the cable through the cable grip. Connect the power supply unit to a wall socket.
- To switch off the receiver, keep the power switch pressed for about 2 seconds. If the unit is not used for a longer period, disconnect it from the mains as it will have a low current consumption even when it is switched off.
Automatic channel scan
Perform the automatic channel scan to select an interferencefree transmission
channel within the current group (UR222D: on each receiver section). To start
the scan, keep the button ◄ or ► pressed until the display indicates
- Do not switch on the wireless transmitter yet. Always set the receiver to an interferencefree transmission channel first.
- When multiple wireless systems are operated in parallel, switch on the wireless microphones that have already been set to a radio frequency before performing the scan, so that the channels already being used will be skipped during the scan.
- The standard display can indicate the transmission channel or the frequency. You can change the current setting in the setting menu (DISPLY).
- Short actuation of the ◄ or ► button allows you to manually select the transmission channel within the current group. After 2 seconds the displayed channel number will be flashing repeatedly until it is stored.

, then the indication will pulsate during IR transmission (about 12 seconds). - When the receiver and the transmitter have been set to the same transmission channel, the receiver’s display will return to the standard display and indicate that a radio signal is being received. The more segments by the RF bargraph are displayed, the better is the reception. The warning (no radio signal) goes off.
- If the channel data could not be transferred to the transmitter, the receiver will display ERROR. Make sure that the transmitter is switched on and the infrared interface is facing the receiver and try again.
Adjusting the level
Adjust the system’s level.
- Speak or sing into the microphone and adjust the gain at the mixer or amplifier. You should now hear the audio signal through the following unit.
- The volume level of the transmitter is indicated on the AF bargraph of the receiver. It is adjustable via the gain setting in the receiver’s setting menu (LEVEL).
Wireless Microphone
Adjusting transmission power and inserting batteries
Open the battery compartment to adjust the transmission power and insert
batteries.
- Unscrew the lower part of the microphone counterclockwise and slide it back as far as it will go. The infrared interface, the selector for the transmission power and the battery compartment are now accessible.
- Adjust the transmission power with the HI/LO 6 selector: position HI = high power for a long range, yet reduced battery life, position LO = reduced range for a long battery life.
- Insert two 1.5 V AA batteries as indicated in the compartment.
- With new batteries, the microphone can be operated for approx. 8 hours. The capacity of the batteries is indicated in the display. Replace the batteries when the battery icon only shows one bar.
- If the microphone is not used for a longer period, please remove the batteries to prevent damage in case of battery leakage
Switching on/muting

Device settings
Keep the SET 4 button pressed for approx. 2 seconds to enter the setting
menu. Use the ◄ and ► buttons to browse the menu items and press SET
to select the desired function.
- Set the transmission power under RF AMP: HIGH = high power for a long range, yet reduced battery life, LOW = reduced range for a long battery life.
- Use the GAIN setting to readjust sensitivity and thus the volume level of the pocket transmitter (0 dB/6 dB/12dB).
- When the LOCK mode is activated, it is not possible to activate muting or switch off the pocket transmitter.
Setting Menu
Keep the SET button pressed for approx. 2 seconds to enter the setting menu. Use the ◄ and ► buttons to browse the menu items and press SET to select the desired function. As long as the display is flashing, settings can be made with the ◄ and ► buttons. Confirm your settings with SET. Then the unit will return to the standard display. If no button has been pressed for a few seconds, the setting mode will be exited automatically. However, any setting made will also be saved in this case.
| Menu item | Function |
|---|---|
| DISPLY | Selects between frequency or channel for the standard display |
| GROUP | Changes the channel group (110) |
| LEVEL | Adjusts the transmitter’s gain |
(6 to +18 dB, adjustable in steps of 3 dB)
Use the gain setting to readjust sensitivity and thus the volume level of the
wireless microphone or pocket transmitter. Reduce the sensitivity if the
volume of the signal is too high and thus distorted. Increase the sensitivity
if the volume is too low and a poor S/N ratio results.
SQUELCH| Adjusts the squelch threshold
(10 to 30 dB, adjustable in steps of 5 dB)
The squelch will mute the receiver when the level of the radio signal received
falls below the threshold value adjusted. Thus, highfrequency
hissing noise will not cause noise at the receiver when the transmitter is
switched off or when the transmission power is insufficient. With a longer
distance between microphone and receiver, a lower value should be selected.
With a shorter distance, a higher value is applicable.
LOCK| Activates/deactivates the lock mode
When the lock mode is activated it is not possible to change values in the
setting menu and to switch off the receiver.
PILOT| Activates/deactivates the pilot tone evaluation
The pilot tone is an inaudible signal added to the transmitted signal by the
wireless microphone. The receiver detects and evaluates the pilot
tone. The pilot tone supports the receiver’s squelch function and prevents
interference due to RF signals from other devices.
