QUESTIONS ABOUT THE DIFFERENT STANDARDS? -

Tuner Formats such as Digital ATSC or Digital QAM J.83B cable

WHAT IS THE ADVANCED MENU? –

The Advanced Menu allows adjustments of PSIP and other tweaks such as the Units RF strength.

Please look at page 12 for more info.

TRYING TO MIX SIGNAL WITH OTHER MODULATORS? –

Please ensure you don’t set our unit on the same frequency as your other modulators as well as

balancing the RF level. If you broadcast our unit on the same frequency as your other modulators it

will cancel each other out or cause unwanted results on your TV image such as two channels split on

one screen. Please see Page 13 for more info.

MIXING OVER THE AIR ATSC SIGNALS WITH OUR UNIT? –

Please see page 14 for more info.

NO AUDIO, OR POOR AUDIO? –

Please ensure your HDMI source audio is set to Stereo PCM or 2 Channel Audio. This is different for

every device. We want to ensure we feed uncompressed 2 channel audio, so the unit does not over

compress the audio which can lead to unwanted results over time. The unit will take care of the Dolby

Digital audio for you in QAM and ATSC standards.

TV WON’T PICK UP THE CHANNEL? –

Ensure you are using the correct Standard that is supported for your TV tuner. Refer to your TV spec

sheet for this information or the manual. If you have other Modulators or RF signals in your

distribution network, refer to pages 13-14.
