Appendix
Q: What are the maximum cable lengths allowed when using the NomadLink network?
A: NomadLink uses a daisy-chain topology to connect amplifiers and an NLB 60E in a network. Standard
RJ45-equipped Cat-5 cables are used throughout. The daisy chain may be made into a closed-loop by con-
necting a return cable to the NLB 60E from the last amplifier.
General rules of cable lengths:
▸
The maximum cable length in between any two devices may not exceed 300 meters / 980 feet.
▸
In a non-closed-loop daisy-chained subnet the maximum cable length is 400 meters / 1300 feet.
▸
In a closed-loop subnet the maximum cable length is 700 meters / 2300 feet.
Exceeding these limits may result in lost contact with the devices, or loss of phantom powering due to cable
resistance.
Q: How long can cable runs be on the Ethernet network connecting the NLB 60E to the PC?
A: On the Ethernet side, normal Ethernet cable limits apply. This is typically a maximum of 80 meters / 300 feet
between each device. Follow standard installation procedures for Ethernet. Distances beyond 100 meters may
require use of a repeater, a format converter, or optical cables.
Q: Why is the NomadLink network a closed-loop topology?
A: Technically speaking, the closed loop is optional. The purpose of closing the loop is primarily to provide a
secondary path to the amplifiers. If cables are broken or disconnected in either direction, all amplifiers still may
be addressed by the network.
Q: How can I be sure that no protection circuits or safety functions interfere with the output signal?
A: If no Clip or Warning LEDs on the front panel light up, you can be fully confident that the rated maximum
output power in the full frequency range is available for your speakers. No limiting or gain-reduction takes place
without a warning or fault indication.
