Kurzweil HUB7, Manual, Page: 40 / 56

Using the HUB7
2-6
The fi rst HUB7 is near the KSP8 cluster and acts as a concentrator
while the second HUB7 is near the RSP8 and acts as a repeater
and power source (although both HUB7s must be plugged into
outlets). The advantage is that only one long cable is necessary
instead of several long cables. Note that in this case only KSP8
ports 1-6 on the concentrator hub may be used, since the repeater
hub uses port 7.
RSP8 power in all of these con fi gurations is controlled
automatically. If at least one KSP8 is powered, then the RSP8 will
also be powered. When all KSP8s are powered off (even if there is
only one), then the RSP8 will be powered off. The hubs are
always on however.
The RSP8 and HUB7s work together at power up to
automatically detect the connection pattern. There are no
con
fi guration switches or menus to worry about. Although hot
plugging of any of the cables is OK, if the connection pattern is
rearranged, you should cycle power so the system can adapt.
HUB7 Connecting Cables
The rules that apply to RSP8 connecting cables (see page 1-4) also
apply to HUB7 connecting cables, with two exceptions. Since
cables connecting to HUB7 inputs do not carry power, they may
be much longer and the wire gauge does not matter. Even the
smallest common wire gauge, #28, can handle the power
requirements for a 300 meter cable.
However, since it is usually impossible to tell which connector
pins form pairs in aftermarket cables, it is strongly suggested that
hub cables be ordered through dealers listed on the Kurzweil
Music Systems web site.
