COMBINING SERVICE PROVIDERS SIGNALS OR ATSC WITH YOUR DEVICE
For Combining ATSC (Over the Air channels) you must find the frequencies that are used by your local
stations. This information can usually be found online by searching for, “(insert your local area) ATSC
frequency chart.” This will give you a nice table that shows all the Frequencies used in your area. Find
the ones that are not used and write those down. Set your device(s) to those unused frequencies. Test
using your Test TV.
Note: For installers, it is recommended but not required to use a Spectrum analyzer to see the
spectrum available to you to make the installation easier. This does not require an expensive unit to
do this. Any Spectrum tester to view the available frequencies will help you in the process.
For combining with a cable service provider, the same rules apply. You can contact the local service
provider of your basic cable to find the frequencies that they use and find the ones that are available
for you to use. If you wish to inject into a Digital Cable Converter box or STB (set-top box) most of the
time the service provider will include a channel you may broadcast onto or some providers require a
specific PID’s to be set which can be set in the ADVANCED MENU in order for the set top box to be
able to read the channel.
AUDIO ENCODING SETTINGS
The unit has three standards of Audio Encoding. Depending on your local and supported format per
TV you can set the following:
• AC3 – 2.1 Dolby Digital Audio US/Canada Standard for Broadcasting
• MPEG – MPEG 2 Layer II used in DVB-T EU Standard.
• ACC - Advanced Audio Coding or MPEG-4. Used in some ATSC broadcasts and ISDBT format.
Supported by Most TV’s worldwide.
If your HDMI source has Compressed Audio or Dolby Digital Enabled, it is recommended to set your
HDMI source to Stereo PCM or Uncompressed Audio to ensure you get a clean audio signal to your TV.
Double compression can cause a lot of audio skipping issues.
