POWER CONNECTION
Power is supplied to the unit via a four finger backplane connector. The RR-0800 can be inserted into
the subrack or removed from the subrack with power applied to the backplane.
FIBER CONNECTION
The fiber optic connection is made via a ST connector located on the back of the unit. Be sure to allow
sufficient room for the required minimum bend radius of the fiber cable used.
BALANCED AUDIO INPUT / OUTPUT CONNECTIONS
The audio input and output connections are made via a five pin terminal block on the back of the unit.
The balanced audio is directly connected to the plus and minus terminals. The shield or earth wire is
connected to the ground terminal. See the drawing above for proper orientation of the audio input and
output wires. Please note that Audio In on the RR-0800 becomes Audio Out on the MT-0800 or RT-
0800 after going across the fiber. The reverse flow follows the same orientation. For optimum
performance the audio wires should be the shortest length practical.
UNBALANCED AUDIO INPUT CONNECTIONS
The audio input connections are made via a five pin terminal block on the back of the unit. To connect
an unbalanced signal to the input, the audio signal is connected to the plus input. The shield or ground
wire is connected to both the minus and the ground terminals. When used in the unbalanced
configuration, there will be a loss of –6dB at the output of the corresponding fiber transceiver. See the
drawing above for proper orientation of the audio input wires. Please note that Audio In on the RR-0800
becomes Audio Out on the MT-0800 or RT-0800 after going across the fiber. For optimum performance
the audio wires should be the shortest length practical.
UNBALANCED AUDIO OUTPUT CONNECTIONS
The audio output connections are made via a five pin terminal connector on the back of the unit. To
obtain an unbalanced output signal, only the audio out plus terminal and the ground terminal are used.
The audio out minus terminal is not connected. When used in the unbalanced configuration, there will
be a loss of –6dB relative to the audio signal input at the corresponding fiber transceiver. See the
drawing above for proper orientation of the audio output wires. Please note that Audio Out on the RR-
0800 originated as Audio In on the MT-0800 or RT-0800 before going across the fiber. For optimum
performance the audio wires should be the shortest length practical.
