spk said:so assuming that the dac is equal in quality i would convert at the receiver. I could be mistaken, but my impression is that analog signals, especially unbalanced, low level signals, are susceptible to noise whereas digital signals, especially optical, are not. So you want to keep your analog signal path as short as possible. HDMI ARC input - if your TV has this, leave it free for audio devices (such as sound bars and home cinema systems) if you can. Use one of the other HDMI inputs instead. Our TV connections wizard will show you exactly how to connect your system. How to connect PVRs and set-top boxes Cable length is a factor when it comes to sound clarity and interference. However, most users are not concerned about it because their AV receiver, soundbar, and TV are close.
There’s scope for eARC to deliver up to 32 channels of audio, including eight-channel, 24bit/192kHz uncompressed data streams at speeds of up to 38Mbps.This means that one can only access 5.1-channel surround audio. This is not something to pout over because it is satisfying by most standards. However, Optical audio doesn’t offer sound profiles such as 5.1.2 or 7.1, or 7.1.2. Moreover, Optical audio doesn’t support Dolby Digital Plus, TrueHD, or DTS HD.
SDI video connections are auto switching between standard definition SDI, 1.5G‑SDI, 3G‑SDI, 6G‑SDI and 12G‑SDI. SDI Video SamplingIn fact, the Sonos Ray soundbar only offers an optical connection, because it doesn’t support Dolby Digital Plus, Dolby True HD, or DTS:X either, so why use HDMI ARC? Yup, optical is still getting used in new products today. But if you want top-quality surround sound with future-proofing built-in, HDMI ARC or eARC is the way to go. Wait, ARC? eARC? Is there a difference? In conclusion, the OREI Audio Converter Extractor + ARC Support + SPDIF + 3.5mm Output HDA-925 is perfect for connecting a new 4K Smart TV with your old receiver to get excellent audio and video quality. However, you cannot connect this HDMI audio extractor to the HDMI ARC port on soundbars. If you are looking for an HDMI Audio Extractor with ARC, we highly recommend the OREI Audio Converter Extractor + ARC Support + SPDIF + 3.5mm Output HD-925.
The benefit of using an optical or co-axial cable is that the other devices connected to your TV, such as PVRs, TV streamers and games consoles, will use your home cinema system's speakers, rather than those on your TV. This will also be the case if you connect via the HDMI ARC port.Firstly, using this HDMI audio extractor, you can extract HDMI signal from the HDMI input and convert it to multichannel audio (SPDIF) or 2-channel analog stereo audio output.
They could easily update both to support full bandwidth, all formats but it's all about HDCP, which is a shame. Also, maybe Toshiba invented the original digital toslink connected but both are S/PDIF, which was created by Sony and Philips.(see below). For those of you using the optical connection, you’ll want to go one step further and choose either PCM or bitstream. Choose PCM if you have a two-channel soundbar, even if it does virtual, fake surround sound. And choose bitstream if you have a surround sound soundbar that decodes Dolby or DTS so that it gets a legit surround sound signal. In the case of HDMI audio extractors with audio outputs only, you can find extractors with analog stereo outs (AUX and RCA). If the audio extractors support surround-sound, you can find digital audio outputs too. Standard Automotive HDMI Cable: This cable type has the same capabilities as a standard HDMI cable, but is used to connect portable or in-car DVD players and other devices to in-car video displays. Extra shielding is provided to suppress interference from other car electrical systems and wiring. The HDMI ARC transmits better-quality audio when you are using a sound bar or AV receiver. It also enjoys the benefits of CEC technology that allows one to use one remote for all the devices connected to the HDMI ARC.
Bottom line
Since the TV is sending audio to the sound bar, you need to connect the sound bar to an output on your TV. In conclusion, the Tendak 4K x 2K HDMI to HDMI and Optical TOSLINK SPDIF + 3.5mm Stereo Audio Extractor Converter does exactly what it is supposed to do. It is reliable and worked perfectly for us. It provides crystal-clear audio and video. If your TV doesn't have HDMI ARC or a port marked HDMI output, then you'll need to use the digital audio output. This will either be an optical or co-axial port, so make sure your sound bar has the matching input.
Great Deal
