CABLE CONNECTIONS
Audio Cables
Always use correctly shielded audio cables when connecting to
the PC260 .
Balanced Input / Output Connections
(Recommended)
To minimize induced noise caused by audio cables and to
maximize the length of cables used, balanced connections are
strongly advised for both Inputs and Outputs . The XLR jacks
provided on the PC260 are configured as pin 1 ground, pin 2 hot
(+), pin 3 cold (-) . Cable shielding must be connected to pin 1 .
Un-balanced Input / Output Connections (Not
recommended)
Un-balanced connections can be made to the PC260, although
induced noise from cabling may be increased . Cables should also
be less than 15” (5m) in length . Unbalanced connections can be
6dB lower in level as well . To match the audio level obtained with
a balanced connection, it is necessary to tie pin 3 to ground at the
XLR connector . This may increase noise .
Digital Input AES/EBU Connection
This connection is wired like the audio analog connection, but we recommend the use of the proper threeconductor, 110-Ohm, twisted
pair cable, do not use a generic MIC cable .
USB Cable
To connect the computer you can use a Type A-B USB cables, this cable is readily available in any computer dealers .
PRONET Cable
Network connections between nodes are via rugged NEUTRIK NE8MC ethercon connectors; these are high quality connectors and
are compatible with standard RJ45 plugs . Node connections are made using standard RJ45 connectors and CAT5 cable . Long runs
should be solid core, but standard is fine . The implication is that stranded is more robust and less prone to breakage, it is therefore
suggested that solid should be used for install applications while stranded is better suited to rental applications . Termination of all
connectors at each END node is essential for the network to function correctly .
The table shows the standard straight-through convention for CAT5 patch cables . The straight-through cable uses the same connection
coding at both ends T568A-T568A or T568B-T568B, these are the most common cable used between network nodes . Bear in mind
though that only Pins 1, 2, 4, 5 are used to link the PRONET network devices .
Any CAT5 or CAT6 cable could be used, we recommend to use the pre-assembled cables with shield in combinantion with the optional
carrier NE8MC, reliable self-made cables require the use of a good crimping tool that usually is too much expensive . The CAT5 or CAT6
net cables are readily available in any computer dealers . The NEUTRIK NE8MC ethercon carrier is available from PROEL .
