UHF System Configuration
In order to maximize performance of the Digital Wireless Receiver DWR-R01D, select the UHF antenna configuration as
described below.
System Configuration
System Requirements
Because the DWX system uses RF transmission in the UHF band, similar to analog wireless systems, antenna
cables of an existing analog wireless system can be used, provided that the frequency matches. When
operating the DWX system along with an analog wireless system, antenna cables can be shared.
The DWR-R01D is supplied with two whip antennas. If the service area is small, you can also use the supplied
whip antennas, but for better reception performance, using the optional UHF AN-820 or AN-01 UHF antennas
is recommended. Select the antenna system according to the scale and purpose of your application.
The supplied whip antennas can be mounted either on the front panel or the rear panel.
Notes
In applications such as on-stage use where the required RF directivity is known, or when used in conjunction
with in-ear monitoring where unneeded directions are known, use the directional AN-01 antennas and install
them with a suitable orientation.
When the direction to the area where the transmitter will be used is not pre-determined, use omnidirectional
antennas to ensure reception from all directions.
BNC cable splitting
Without a divider, cascaded connection*
If 9 or more DWR-R01D units are to be used, use the Antenna Divider WD-850 to split the BNC connection.
One WD-850 unit allows splitting into 4 outputs, and cascaded connection of two WD-850 units allows splitting
into 8 outputs.
Number of DWR-R01D units
2 to 8: Cascaded connection of DWR-R01D units without using WD-850*
9 to 32: One WD-850 in conjunction with cascaded DWR-R01D units
33 to 41*
*1 Cascaded DWR-R01D output reflects attenuator settings.
Set ANT DC OUT to [OFF] and ANT ATT a/b to [0dB] on second and subsequent DWR-R01D units to which antennas are not
connected directly.
*2 When configuring two diversity reception systems, the WD-850 is used to join the systems.
*3 Due to network limits such as RMU-01 control and Wireless Studio combined monitoring capability, the DWX system supports a
maximum of 82 channels in a networked configuration. If not configured as a network system, more than 82 channels are possible
as far as frequency allocation allows. (In this case, the status of transmitters received by the DWR-R01D can be monitored at the unit
itself.)
When two WD-850 units are used, a UHF system with a maximum of 128 channels, using 64 DWR-R01D units, can be configured.
