Appendix C – Paralleling Inputs
To parallel inputs between more than two enclosures:
Important: Signal cables B and D in FIG. 108 need to be approximately 3.0 in. (7.6 cm) long.
Signal cables C and E should be just long enough to reach from enclosure to enclosure.
1.
Fasten the first T-connector to signal cable A, which comes from the source device.

2.
Fasten one end of signal cable B to the first T-Connector.
Fasten the other end of signal cable B to the input on the first enclosure.
3.
Fasten one end of signal cable C to the first T-Connector.
Fasten the other end of signal cable C to an open end on the second T-Connector, per FIG. 108.
4.
Fasten signal cable D to the second T-Connector.
Fasten the other end of signal cable D to the corresponding connector on the second enclosure.
5.
Fasten signal cable E to the open end on the second T-Connector.
Fasten the other end of signal cable E to the corresponding connector on the last enclosure.
The source is ready to switch to outputs on all enclosures (for information on controlling parallel
inputs, see page 169).
