SuperPro Series Installation Manual
Hub Installation:
Hubs install in the lower expansion bays. Four screws are used to secure the hub in place. The
Service Input Hub should usually be installed at the bottom of the installed hubs.
Hub Hookup:
Cable TV or Antenna is input on the port on the front of hub labeled “
CATV IN
“. Modulated signals
that come off of a modulator are input on one of the 4 input ports labeled “
Modulated Inputs”.
Modulated signals should be assigned to channels that have an open channel both above and
below the channel where you are modulating too.
Note: Never hook-up cables to coax hub from Satellite dish (LnB) to the receivers. There
is a DC voltage on those cables that can cause damage to the hub and to TV hooked up to
the hub.
Power is input directly into the hub using coaxial cable run to the provided 12V Transformer plugged
into a standard 110VAC outlet. Note: The coax hub will not work without the power.
Once the inputs are hooked up the output signals should be available to use. Outputs contain both
the incoming CATV/Antenna signal and any modulated signals you have fed into the modulated
inputs. Keep terminating resistors in place for all unused outputs.
To have the optimal picture you need to have between 0dBmV to +10dBmV at the plate location at
the room. Also be aware that just like you cannot have enough dBmV signal strength and have a
poor TV picture, you can also have too much dBmV signal strength and over power the TV tuners
and have poor TV picture.
You can use attenuators to bring the signal down to the range it should be. Most attenuators come
in –3dBmV, -6dBmV, -10dBmV, -12dBmV, -16dBmV, and -20dBmV. The attenuators are placed
between the incoming services if the service line dB range is too high. Or the attenuators can be
placed in the
individual TV
location where the
dBmV coming off
the plate is too
high. The antenna
and cable input
into the system
should be
between
+12dBmV to
+19dBmV to
optimize picture
quality.
When you are
using Antenna or
Cable TV and
modulated
signals, before
they go into the
coax hub both
signals need to be varied that they are within 5dBmV of each other. For example if your cable TV
coming from the street is +19dBmV the modulated signal going into the module should be between
