DTV Converter Box
Analog Pass-Through Feature
If you receive over-the-air TV signals from a low-power TV
station that does not have to switch to "all digital" next year, you
will still be able to receive those analog signals after the Digital to
Analog Transition.
If you also receive TV signals from a full-power TV station
that will be switching to all digital, you need to consider what type
of converter box to buy. The converter box changes the digital signal
to an analog signal to view on your TV set.
If you want to be able to watch channels from both analog and
digital TV stations, you may want to buy a converter box that will allow the analog signal to pass through to your TV set.
If you do not purchase a converter box with an analog
pass-through feature, you may have to physically disconnect the box
every time you change from a digital channel to an analog channel.
RV Owners: A converter box with an analog pass-through is a great choice while traveling. It will allow you to receive TV signals from various TV stations wheather they are transmitting in analog or digital.
There is a way around having to disconnect the converter box every time you switch from a digital to an analog channel.
If you have sufficient signal from your antenna and your television has an audio/video input, you can use a DTV converter box without an analog pass-through. Here’s how:
Use a 2-way splitter to split the signal coming from your antenna. Connect the antenna to the input side of the 2-way splitter, connect your converter box to one of the outputs of the 2-way splitter. Connect the other output side of the 2-way splitter to the RF (antenna in) on your television. Next, connect the audio/video output from your converter box using an audio/video cable to the audio/video input of your television. To watch digital programming, switch your television to video input and change channels on your converter box. To watch analog programming, change the channels on the television set.
Another option is to use an A/B Switch instead of a 2-way splitter. The only difference is you will have to use the A/B Switch to switch the antenna signal from the converter box to the television every time you want to switch from a digital channel to an analog channel.
