For details on gain of antenna booster, refer to the
operating instructions supplied with the antenna.
Notes
• The cable loss may differ depending on the manufacturer
of the cables.
• The rated resistance of ANTENNA a/b IN connectors is
50 Ω. If the cable with 75 Ω resistance is used, actual
signal loss is usually a few dB lower than the values on
the table above.
e AC IN connector
Connect to an AC power source with the supplied AC
power cord.
f DC IN connector (XLR)
This connector connects to an external +12 V DC power
supply.
The DC IN pin configuration of the unit is as follows.
Pin No. Function
1 –
2 NC
3 NC
4 +
Note
Make connections using proper polarity. Incorrect polarity
may damage the unit.
Always check the polarity before making the connection.
AC power supply is prioritized when operating the unit.
To stop DC power supply, turn off the connected external
power supply or disconnect the connected cable.
g ANTENNA a/b OUT (antenna a/b output)
connectors (BNC-R)
These connectors output the signals input from the
ANTENNA a/b IN connectors. Using these connectors,
you can connect up to eight of DWR-R02DN units in
cascade.
h REM ANT (ST remote system antenna)
This is an external antenna for the ST remote system.
i WORD SYNC IN/OUT (sync signal input/output)
connectors and 75 Ω termination switch
When you want to synchronize digital output with an
external sync signal, input the external sync signal to the
WORD SYNC IN connector.
RG-213/U
14 dB 9 dB 11 dB
28 dB 18 dB 22 dB
The sync signal input from the IN connector is output from
the OUT connector.
Set the 75 Ω termination switch of only the DWR-R02DN
unit at the end of the cascade connection to ON.
For details on connecting to the WORD SYNC connectors,
see "Connection Example of Word Clock and Audio" on
page 16.
