Question

I'm upgrading sound equipment in a school.  I connected my SL32 Series III to a 16R for a meeting using a CAT5e wire that is run through walls and it worked great.  I tried that same connection today but using the SW5E and it would not connect.  Using a short CAT5E cable right at the switch worked but not when I used the 200' line that was installed when the building was built 10 years ago.  I knew the risk of using existing wiring which is why I tested (very successfully) point-to-point before purchasing more gear.

I'd appreciate any ideas you my have.
Thanks

Answer 1

You need to ensure all cabling is suitable for AVB audio.

Answer 2

If the installation is old, it might be done for 100Mbit and might only use half of the pairs compared to gigabit standard.

Best option would be to use a good cable tester like Fluke and check if everything is ok. If you can connect computers and get gigabit it should work but there is no guaranty.
