StudioHub+ Model HUB16-DC and HUB8-DC

Engineered for StudioHub+ and High-Speed Ethernet Connectivity

Model HUB16 pictured

Also available as Ω hub 8 channel - model Hub8

Product Key
Name HUB16 / HUB8
Mount Hub (3 r.u.)

Channels 16 / 8

CAT-5 Pairs 4 (all)

Power Link yes

Connectors 2 RJ-45 & 110

Versions Full Hub/Half Hub/Board Only

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 optional +/- 15 DC
voltage. Equipment cabling may also be punched down to
the inline 110 connector.

DC Power

If using any StudioHub+ "DC-Link" accessories, plug a
StudioHub +/- 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 StudioHub+ 15V power supply
connected to the hub, and JU-33 is jumpered, chassis ground,
electrical ground, and shield are common.

StudioHub+ 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 100­style 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 StudioHub+ "DC-Link" accessories, plug a
StudioHub+ +/- 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
StudioHub+ 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.

Power & Ground Programming

Note: These connecters are in parallel

3 groups of + and ground connections are
available. Each group feeds 3 sets of 4 RJ­45 connectors.

To send DC to pin 8 of the RJ-45's in group 1
(RJ-45's 1-4), apply DC to screw terminal +1
or 110 connector pin +1. Then install jumper
JU2, JU4, JU5, JU6, or JU8 at each RJ-45
where DC needs to be present.

To send ground to pin 5 of the RJ-45's in
group 1 (RJ-45's 1-4), apply ground to screw
terminal -1 or 110 connector pin -1. Then,
install jumper JU1, JU3, JU5, or JU7 at each
RJ-45 where ground needs to be present.

Repeat (with appropriate screw terminal and
jumper numbers) for RJ-45 group 2 (RJ-45's
5-8) and group 3 (RJ-45 9-12)

Note that if the same DC voltage or ground
connection is needed between groups, the
DC or ground lead can be connected in
parallel at the lower screw terminals or the
110 connector.

Connect DC voltage and/or ground at this 110
block or screw terminal to apply ground or DC
voltage to these RJ-45 jumpers. (See below for
specific programming instructions).

StudioHub+ Model MINITIE12-4 & MINITIE24-4

Engineered for Inter-Studio Tie Lines

General
Mini Tie Hubs provide multi-pair inter-studio connectivity by
splaying out CAT-5 25 pair cable to individual RJ-45
connectors via a 50 pin RJ-21 mass connector. Mini Hubs are
designed to mount and fit where the capacity of full-size hubs
is not needed. Depending on the model selected, either 2 or
4 CAT-5 pairs are connected to each RJ-45 connector.
Double the density is achieved if only 2 pairs (4 wires) are
required to connect to each RJ-45. Generally, 2 pair is
sufficient to support StudioHub analog and digital audio
circuits. All 4 pairs (8 wires) are needed to support KVM and
other special multi-wire equipment circuits.

Mounting
Mini tie-line hubs are available in single units on small wall­mountable plates, or in double density on 1 r.u. rack mounts

Grounding Information.
RJ-45 connector shields are common on the mini tie hubs.

Two jumpers are provided that allow the unused CAT-5 25

th

pair to be connected to this common shield, as well as to the
hub chassis.

Each RJ-45 provides 4

wires of connectivity via
the CAT-5 25-pair cable

General

The StudioHub+ 44 position patch panel provides 22 stereo analog or digital outputs and inputs on
a 3 r.u. rack panel via RJ-45 connectors. Standard RJ-45 shielded or non-shielded straight-thru
patch cords of 18 or longer may be used to make patch connections.

Normalling

Front panel accessible normalling dip-switches establish a quarter normalled full-time
connection between the upper and lower output and input connectors so that signal in made without
the use of a patch-cord. Note that when the normalling function switch is on (up,) signal flow is not
interrupted by inserting a RJ-45 patch cord in either the upper or lower circuit connector.

Rear Panel Connectivity

44 Rear panel RJ-45 s are provided in parallel with the front panel connectors for plug-and-play
wiring ease to the panel. In addition, rear panel 110-style punch blocks are in-line for every circuit
to allow cabling access to every signal. Note that the panel passes 2 pairs (pins 1, 2, 3, &6) of the
CAT-5 cable, leaving pairs 3&4 unconnected. This makes the panel compatible for StudioHub+
analog and digital audio connectivity as well as certain Ethernet applications, but not CAT-5
circuits requiring other then pairs 1 & 2.

Grounding Information.

RJ-45 connector shields are isolated from each other but may be optionally connected in common
by inserting a jumper on the rear of the panel by each connector. A jumper is also provided to
connect the RJ-45 shield bus to the patch panel chassis ground.
