It isn’t quite as compressed as Dolby Digital. It is very uncommon with streaming media, though. The other is DTS, which is also a common audio format and is also found on most DVDs and Blu-rays.

There is Dolby Digital 5.1, which is a very common audio format, found on DVDs, Blu-rays, and most streaming media, and is a bit more heavily compressed. There are two main kinds of Bitstream signals. You can do this both via HDMI ARC and digital optical. Without that ability to decode the signal, a receiver will not be able to unpack and play a given Bitstream audio signal.Īt present, you must use a Bitstream signal if you wish to pass 5.1 audio through a TV. It also means that a receiver needs to have the ability to decode a particular Bitstream audio format to play it.

This delivery method makes for a smaller signal size, and so it is easier to send multiple channels of audio. With Bitstream, the audio signal (basically instructions telling the speakers what to do) is encoded (packaged) by the source device, and then sent to be decoded (unpacked) by the receiver, with the resulting information then telling the speakers what they are meant to play. This does reduce the quality somewhat, but it’s important to note that compressed audio still sounds very good – good enough that the average person is not going to hear much difference between it and uncompressed audio. The three most common are Bitstream formats called Dolby Digital and DTS, which are both compressed, and then PCM, which is uncompressed.īitstream audio is compressed, meaning information that is deemed less important to the sound is removed from the signal. There are several different kinds of audio encoding used to deliver surround sound in a video. The 5.1 audio signal is transmitted via the existing HDMI connection from the sources and into the TV and then sent by the TV down the audio output and to the receiver.ĭepending on the number of sources you have, and whether they all support the 5.1 signal types you want to use, this kind of setup can eliminate several extra cables, and without noticeable impact on sound quality. With 5.1 passthrough, instead of needing to connect a separate wire from each source to the AV receiver for the audio signal to make it to the receiver, a single audio connection is established between the TV and the receiver. In a typical setup, multiple source devices will be connected to the TV via HDMI, a cable which can transmit both video and audio. You also benefit from having a dedicated subwoofer, as that provides deeper bass than you would get from regular speakers. Plays deep bass.Īll six speakers receive and play their unique audio channel, and having five speakers in different places, each playing different sounds, adds a sense of space and direction to the audio that you would not get with stereo setup (2.0). Subwoofer: Should be placed on the floor to the side of the TV.

These are mostly for playing sound from action occurring to the side and rear of the camera’s point of view. To the sides: One speaker each to the left and right of the seating area. For the most part, these handle dialogue and the sound of onscreen action. In front: One speaker to the left of the TV, one in the center (either just above or just below the screen), one to the right. The speakers are ideally positioned as follows. ‘5.1’ is the typical surround sound setup, and involves five (5) ‘regular’ speakers, and one subwoofer (which is the ‘.1’ in '5.1'). Here are a couple of examples of home entertainment setups that take advantage of a TV's 5.1 audio output and passthrough.Īdditional information 5.1 surround sound setup In short, 5.1 passthrough is just an option that allows you to get surround sound for multiple source devices, with few cables. This image is an example of a 5.1 surround sound setup with a TV that doesn’t support passthrough. If you use the TV’s speakers, or just use a 2.0 (two speakers) or 2.1 (two speakers + one subwoofer) sound system, you don’t need to worry about 5.1 passthrough.Īnd keep in mind that 5.1 passthrough isn’t a necessity. Note that some TVs can only pass 5.1 through over a certain connection (either digital optical or HDMI ARC), and some can only pass through certain signal types (DTS or Dolby Digital), so make sure you pick a TV that supports both the connection and signal type you wish to use. At least one source device capable of outputting a 5.1 audio signal.A 5.1 speaker system with an HDMI ARC or digital optical input.5.1 passthrough is only useful when you have the following:
