DTP CrossPoint 4K Series Matrix Switchers • Installation 21
Extron recommends using the following practices to achieve full transmission distances up
to 330 feet (100 m) and reduce transmission errors.
• Use the following Extron XTP DTP 24 cables and connectors for the best performance:
• XTP DTP 24/1000 Non-Plenum 1000’ (305 m) spool 22-236-03
• XTP DTP 24P/1000 Plenum 1000’ (305 m) spool 22-235-03
• XTP DTP 24 Plug Package of 10 101-005-02
• If you are not using XTP DTP 24 cable, Extron recommends, at a minimum, using
24 AWG, solid conductor, STP cable with a minimum bandwidth of 400 MHz.
• Terminate cables with shielded connectors to the TIA/EIA-T568B standard as
straight-through (patch) cables only (see figure 17 on page 19).
• Limit the use of more than two pass-through points, which may include patch points,
punch down connectors, couplers, and power injectors. If these pass-through points
are required, use shielded couplers and punch down connectors.
NOTE: When using cable in bundles or conduits, consider the following:
• Do not exceed 40% fill capacity in conduits.
• Do not comb the cable for the first 65 feet (20 meters), where cables are
straightened, aligned, and secured in tight bundles.
• Loosely place cables and limit the use of tie wraps or hook-and-loop fasteners.
• Separate twisted pair cables from AC power cables.
Analog audio input connectors
See figure 18 to wire a connector for the appropriate input type. Connectors are included
with the switcher, but you must supply the audio cable. Use the supplied tie-wrap to strap
the cable to the extended tail of the connector.

NOTES:
• The length of exposed wires is important. The ideal length is 3/16 inch (5 mm).
• If the stripped section of wire is longer than 3/16 inch, the exposed wires may
touch, causing a short circuit.
• If the stripped section of wire is shorter than 3/16 inch, wires can be easily pulled
out even if tightly fastened by the captive screws.
• Do not tin the power supply leads before installing them in the connector. Tinned
wires are not as secure in the connector and could be pulled out.
An unbalanced stereo audio connector consists of a tip, ring,

and sleeve. An unbalanced mono audio connector consists of a
tip and sleeve. When you are making connections for the
switcher from existing audio cables, see the drawing at right to
identify the tip, ring, and sleeve parts of the connector. The ring,
tip, and sleeve wires are also shown on the captive screw audio
connector diagrams, figure 18, figure 19 on the next page, and figure 20 on the next page.
