What is HDMI Pass-Through?

Last Update date : 2017.10.24

HDMI Pass-Through passes video and audio signals from a High Definition (HD) source such as a Blu-ray player or a HD Set Top Box to a Home Theatre System (HTS) via a HDMI cable. The Home Theatre System plays the audio from the HD source through its own speakers and sends the unaltered video signal to a TV via a second HDMI cable.


A Home Theater System that supports HDMI pass-through will have one HDMI OUT port to send the HDMI signal to a TV, and at least one HDMI IN port to receive a HDMI signal from the connected external device.



Advantages of HDMI Pass-Through


●    It provides an easy, single cable method of sending HD audio formats such as Dolby True HD, DTS Master Audio, and 7.1 surround sound from an HD source to a Home Theater System. The only alternative method requires you to connect eight audio cables.


●    It sends HD audio formats in digital form. The eight audio cable connection method transmits only analog signals.


●    It passes the digital, 1080p video signal from the Blu-ray player or Set Top Box to the TV without altering the signal. You get top of the line video and audio formats, all in digital and high definition. 


NOTE: HDMI Pass-Through does not work with all devices. Before attempting to set up an HDMI Pass-Through connection, make sure the source of the signal such as a Blu-ray player or Set Top Box, supports HDMI pass through.

Below is a diagram of an HDMI Pass-Through connection:





For TV and Home Theatre System connection only (No STB, or TV Pass Through connection):


If your TV does not have HDMI Out, pass through can still be configured by using HDMI ARC (Audio Return Channel) port or an Optical Cable connected to the TV's Digital Audio Out port going to your HTS Digital Audio In port.


Do not forget to set your TV speakers to External.
