Can this be fed an optical input and output 5.1 without a computer, say from an optical port on a DVD or tv then fed into an amplified 5.1 system? A: "I don't believe so. As far as I can see, the USB port is the only power source." Q:So if I powered it...

I don't believe so. As far as I can see, the USB port is the only power source.

Yes it is. I have both an optical input and a USB input and I am able to switch between the two. Occasionally, I have to switch it off to get the signal light, but that's only happened a couple of times. I cannot answer as to how it responds if you have all 3 inputs in, as to whether it only selects the one that is "on".

It has an optical input. As long as your amplifier has an optical output, that is the best way to go.

There is NO USB input on this amplifier. There are 2 analog RCA inputs. You would need a separate DAC unit to go between this and your source component.

Yes, just hook the optical output of the tv into the dc-1. And make sure not to try and pass thru any 5.1 from the tv as this will result in silence thanks to the hdcp copy protection.

NOPE. A usb port, as far as I know, can only put our 2.5 watts max output. Which, for powering this amp would be hilariously insufficient and could also burn out your usb port if used at that power continuously. The wall-wart that comes with it is 24 watt and that's even far, faaarrrr too little. While a usb powered version of these amps would be nice (I can think of several uses), I highly doubt there's enough wattage there for this one.

Sorry, Mark, but I have not tried either. My perception is that you need an AMPLIFIED source of audio such as audio out from an amplifier or TV, but it's possible that your DVD player and/or Dish will have sufficient amplification to work fine. My recommendation is to call the manufacturer's support line and ask. The documentation is so good that I'll be surprised if they cannot give you a quick and authoritative answer--they really seem focused on keeping the user happy. I continue to be very, very pleased with my ZVOX 555. My wife and I love that we can actually hear and understand virtually 100% of the dialog from the satellite, local channels, and DVD, sooooo much better than playing it through our stereo amplifier/receiver. My only wish is for a little more bass. We're leaving in a few days for summer away from our home here in Florida, but when we return in the fall I plan to look into adding a subwoofer to the system to provide more bass. The ZVOX 555 has a subwoofer output and there are plenty of small subwoofers available, so I don't think getting a little more bass be an issue. Wish I had a more complete answer for you!

I bought the Bifrost for optical input from AppleTV. I don't know about USB and never checked for it because I wanted to run Toslink from ATV to Bifrost. It sounds great with that setup.

Yes, in this case, your TV output is the weakest link and is down-converting all of your content to 2.1. In order to get true 5.1, you'll need to connect each of your devices separately. I ran into this exact problem :(.

It has no 'amps' per se. This is a passive,not powered, hub so it will be able to source no more total current that the USB port that it is connected to.

i have plasma "optical out" and i have my receiver with 'RCA input only" with 5.1 Speaker out, do this adapter work to have 5.1 surround sound. My receiver is only RCA Input, and i want 5.1 out, NOT Stereo?.

Optical can not accept a 5.1 signal. It will downscale it to 2 channels. Your receiver will then split the signal to simulate 5.1 sound. You will need a HDMI cable in to get 5.1. Get an HDMI cable and hook it up like this PS3-->Receiver-->TelevisionLook for a reciever that can pass a 1080p signal.

I have not tested the optical or coaxial output since I only use the HDMI output. The audio input can be either optical or coaxial. I would conditionally assume that the optical output is active if the optical input is used. The same for coaxial. I would not assume without testing if the coaxial input will feed the optical output or the reverse. A note of caution. Every time you process your audio and video signal you increase the sync error between the audio and video data streams.

5.1 Surround Sound is a product of the A/V signal itself. You can get a AV Receiver and hook the signal to it and then come out of the audio system (AVR) HDMI to your TV, and since the signals are all digital, there will be no degradation of the quality. My girlfriend has an older 5.1 system that gets its audio information encoded from the video signal, and uses an older Composite (yellow) video signal to decode the audio information. You can even get the audio from an HDMI on some systems. Check with the system you are interested in...and then shop around for others. On the back there is one stereo headphone jack that you can use as a stereo analog signal to hook up to a regular stereo system/amp/etc. Here is what LG has to say about that TV: Daniel: Hello Joe Smith. Welcome to LG Electronics U.S.A. Support only. How may I provide you with excellent service today? Joe Smith: Hello - Joe Smith: Concerning the 47LA6200, does it support Surround Sound and if so, what port do you hook up a system to? Daniel: I would be happy to help you with that. Daniel: I would like to please place you on a brief hold while I research that for you, will that be alright? Joe Smith: YEs, thank you! Daniel: You are welcome. Daniel: Thank you for your patience while I researched that for you. Daniel: You can hook up a sound system on the optical port. Joe Smith: Does it support 5.1 Surround or just stereo? Daniel: It will support both. Joe Smith: Thanks...have a great day! Daniel: You are welcome! is there anything else I can assist you with today? Joe Smith: Nope, that's it. Love my LG TV! :-)

Cant exactly understand your question, if using without computer where do you take input signal from? This device has only VGA input (no rca input) One thing i can tell for sure: without usb power supply device doesn't work at all.

I assume you are looking to run the audio out from TV to an audio receiver or similar. The Audio Return Channel (ARC) running through the HDMI connector labeled for ARC appears to only support stereo (2 channel) audio. The original source should be irrelevant. I have a Sony 7.1 channel audio receiver hooked up and attempted to run all my sources (Verizon FIOS box, PS3, etc) directly into the TV and then have it forward the audio to the receiver via ARC in order to avoid having to use the HDMI video switching in the receiver. However I found that it took my 7.1 sources and only passed through 2 channels (L/R)!!! It's not clear whether the TV internals or the connection is limiting this, but if you dig into specs you'll see that the quality of audio that you'll get via ARC is dependent on what the device is built to send through and TVs often only support 2ch as their own built-in speakers are limited to this. With this TV however, you do have the option of using the optical audio out connector from the TV to receiver which does support 5.1. It does NOT support 7.1. Since I refuse to have two useless speakers I had to wire all sources back through the A/V receiver first and then a single HDMI out to the TV so the TV is not in the audio path at all. The drawback is less clean input source changing but I can live with that. The only exception is when the TV itself is the audio source for example when using the Apps like Skype, Amazon VoD, HBO Go, etc. For those I used the optical audio out from TV mentioned above which results in a good 5.1 to my audio system (I doubt the apps or their content really support 7.1 anyway). Sorry for the lengthy explanation, but as I learned there are a lot of details to this. If you only care about 5.1 and not 7.1, then I suggest you use the optical audio instead of ARC and then it should work fine at the very least for any HDMI input to the TV (I haven't tried any others).

It seems clear that this unit does not come with a power supply, but seems to have a standard barrel connector to accept an optional power supply. To use small external (2.5") drives I need to have an external power supply. Can someone post a link to a power supply that will supply at least 2 amps and is compatible with this 4-port Sabrent hub?
