Do I need Analog Pass-Through?

“If you purchase a digital-to-analog converter box to watch digital broadcasts on an analog TV and also wish to continue watching analog LPTV, Class A, or TV translator stations, you should purchase a converter box with “analog pass-through” capability, which allows analog broadcast signals to pass through the converter box to be tuned by your analog TV. NTIA’s TV Converter Box Coupon Program has certified converter box models that have analog pass-through capability.


You can find out which boxes have analog pass-through via our online comparison tool.
The NTIA will mail a list of current coupon-eligible converter boxes, noting with an asterisk those that have analog pass-through capability, to each household that receives converter box coupons. You can also check with your retailer to determine whether the converter box you are purchasing has analog pass-through capability.


If you purchase a digital-to-analog converter box without analog pass-through capability, you may have to connect an antenna switch or a signal “splitter” to bypass the box if you wish to view analog TV broadcasts. Check with the manufacturer of the digital-to-analog converter box and your retailer if you need instructions on how to connect the box to view broadcasts from both analog and digital stations.”
