3.1.2 Output Connections
The IS-HUB4 utilizes standard Cat-5 (or Cat-5e) cable to send both sig-
nal and power to the nodes connected to its ports. Regular Cat-5 patch
cables may be used, purchased in standard lengths or cut and crimped
for the installation. If making your own cables, standard A or B patch
cable wiring can be used or straight through connections between pin
1-8 to pin 1-8 on either end.
Crossover cables or wiring cannot be
used.
Each port is capable of outputting a maximum of 20 total watts of pow-
er to the nodes daisy chained on that port.
CAUTION: Do not connect the Hub or Amp Nodes to any
other devices (such as a network router or switch). They
are not internet capable and will damage other devices.
The total power output of the IS-HUB4 is limited by the power rating of
the power supply which was purchased with the system and cannot
exceed 80 Watts.
Each IS-Hub4 port is capable of outputting a maximum of 20 watts of
speaker power. This 20 watts is available for the IS-AmpNode-10/
speakers daisy chained to the port.
If you would like to upgrade the chosen power supply, please contact
your local sales rep for details.
3.2 Node Installation
The IS-AmpNode-10 contains a single channel micro amplifier capable
of delivering up to 10 watts of power to a single speaker.
If you have purchased the IS-SP4 speakers as a part of your IntraSound
system, the amplifier can be secured into the top of the speaker. To
secure the amplifier node, place the node on top of the speaker insert-
ing the screws on the top of the speaker into the notches on the rear
of the amplifier. Twist the node clockwise and it will lock into place.
To secure the amplifier node to another type of speaker, Stewart Audio
recommends industrial strength Velcro for easily installation.
3 System Installation
CAUTION: Before installing your system, make sure that
you have read the Important Safety Precautions at the be-
ginning of this manual.
3.1. Hub Installation
Stewart Audio recommends that the unit is secured in some fashion to
prevent movement of the unit if one of the cables is pulled during in-
stallation of an amplifier node.
