St Model HUB16-DC and HUB8-DC
Engineered for St and High-Speed Ethernet Connectivity
General
Each of 16 (or 8 if ordered in the
Ω
Hub model) Hub
channels consists of an RJ-45 input connector in parallel with
an output RJ-45 connector and a 110-style punch connector.
Each channel carries a stereo balanced audio pair, or
balanced digital audio signal, and an op/- 15 DC
voltage. Equipment cabling may also be punched down to
the inline 110 connector.
DC Power
If using any St "DC-Link" accessories, plug a
Stu/- 15 volt power supply into the power supply
connector. Both Hub LED s will illuminate. Insert both
power jumpers and the DC ground jumper on only the
circuits that utilize a powered accessory (e.g. MatchJack, mic
preamp, etc.).
Grounding Information
Cable and connector shields are contiguous from each
individual hub channel (input to output) but are normally
isolated from other channels.
To use the hub as a common ground point, insert the jumper
below each left-hand RJ-45 that you want common to the
chassis ground. If you have a St 15V power supply
connected to the hub, and JU-33 is jumpered, chassis ground,
electrical ground, and shield are common.

HUB8-DC
Rev: 01/05
Note:
All 3 of these
jumpers must be inserted
for any channel that is
powering a remote DC-
Link device (e.g.
St MatchJack
or Pre-Amp)
