7.2 BALANCED WIRING TIPS
7.2.1 Phoenix terminal blocks
To make balanced connections, remove the terminal blocks from the rear of the DDRC-88A. Connect individual
wires from a shielded pair cable to each set of screw terminals as shown below. After all connections to the
terminal block are secure, firmly re-insert the terminal blocks.
7.2.2 XLR adapters
If connecting the DDRC-88A to equipment that uses XLR connectors, suitable cabling can be made by cutting
XLR-XLR or microphone cables in two. The two halves are then used for input and output, as shown here:
7.2.3 RCA adapters
In certain special cases, it can be helpful to connect a balanced input or output of the DDRC-88A to an
unbalanced (RCA) connection on the source or power amplifier. The connection scheme is shown below. Note
that the cable shield must be connected to the ‘−’ terminal on the DDRC-88A input, whereas on the output side,
the ‘−’ terminal is not connected.
