Rev: 01/05
St Model HUB18-DC
Engineered for Break-Out Harnesses
General
Each of 18 Hub channels consists of two 2-pin mini-Amp
input connector in parallel with an RJ-45 connector and 100-
style punch-down connector. Each channel carries a stereo
balanced audio pair, or balanced digital audio signal. Custom
length and configuration harness cables must be factory
ordered to interconnect the Hub to various consoles, audio
routers and engines or multi-channel Digital Audio
Workstations.
DC Power
If using any St "DC-Link" accessories, plug a
St +/- 15 volt power supply into the power supply
connector. Both Hub LED s will illuminate. Insert both
power jumpers and ground jumper only on only the circuits
that utilize a powered accessory (e.g. MatchJack, mic preamp,
etc.).
Grounding Information
RJ-45 connector shields may be isolated from each other or
optionally connected to each other or to the hub chassis by
inserting jumper by each connector.
To use the hub as a common ground point, insert a jumper
above any left-hand RJ-45 for any channel that you want to be
in common with the chassis ground. If you have a
St 15V power supply connected to the hub, to
connect a channel to the power supply shield, insert a jumper
above any right-hand RJ-45 of that channel.
