AUDIO VIDEO INPUTS:
Your unit has 4 independent channels / inputs, each with analog & digital connectors, you can select via software per
each of the channels:
HDMI Input : Connect your Digital audio/video with one single hdmi digital cable – this is the best quality solution
NOTE : you can use this port to input Dolby Pass Through stereo / 5.1 / 7.1
Component Input : Connect your RGB analog HD/SD video using the RED GREEN BLUE RCA
Composite Input : Connect your CVBS composite SD video using the RED RCA out of the RGB set
Closed Captioning Input : Connect your CVBS CC signal to the YELLOW RCA marked CC
Analog L/R Audio Input : Connect your L/R analog audio to the RED / WHITE RCA marked AUDIO
OPTICAL Digital audio ( option ) : Connect your TOSLink optical audio to the TOSLink optical ports
NOTE : you can use this port to input Dolby Pass Through stereo / 5.1 / 7.1, alternative to the HDMI
RF COAX OUTPUT:
Your unit has 1 RF Coax out port, F-TYPE
This output is already amplified and goes directly to your coax splitter box from where all the coax cables distributes to all
your TVs.
This output is already amplified and usually does not require additional external amplifiers
The level can be adjusted up to +45 db millivots
IMPORTANT : SHOULD YOU USE ESTERNAL COAX AMPLIFIERS, YOU MIGHT NEED TO REDUCE OUR POWER
OUT IN ORDER TO AVOID SIGNAL DISTORSION OF THESE AMPLIFIERS
The typical symptom is pixelisation or signal lost on the TV, please remove your amplifiers or reduce our power
out in single steps until the picture on your TVs is perfect.
Should you have a spectrum analyzer you can also adjust the levels through it for the perfection
Coax out : Connect to your distribution splitter to all the TVs. You can also connect directly to one TV without any risk,
also full power, as all the TVs supports +45dbmv input with no problem and have the agc automatic gain control
Coax In : Connect to an incoming coaxial feed with third party channels, as from cable operators, or your indoor/outdoor
antenna. The injected channels are mixed with the VECOAX channels and output mixed to the RF OUT connector.
NOTE : The insertion loss is 6 db TYP, as any passive combiner, so you will need to compensate the incoming signal of 6
dB to get the same original level you apply to the input. You can also add a coax amplifier before entering the Coax in.
IMPORTANT: Cable providers might have special signals on their coax. It is a common practice to inject our
coax output to the coax combiner, avoiding to pass-through our unit the cable operator coax feed and their
special signals, so we do not change their specific signal path.
IMPORTANT: Do your first tests on a simple test bench, connecting a test TV directly with a short piece of coax to
our RF COAX OUT, scanning for channels. Leave other channels feeds disconnected at first.
