Question: Will this unit convert any optical signal other than PCM?
Document: 1. I received this unit 5 days earlier than what I was told I would get it.2. This unit did just what it was suppose to do. It converted the optical signalto a digital signal for an rca hookup.3. I have only used it for several days and it has proven to work as it should sofar. Only time will really test this units' ability to hold up.
I am using this to take the optical output from my TV to convert to a coax digital signal to plug into the 2nd input on my DAC. It worked instantly the first time. No hiccups. No random disconnections. No heat buildup. Its been powered up basically a solid week and I intend on just leaving it powered up continuously. I havent measured power usage, but it cant be much at all. It is cool to the touch after days and days.
Did not work. Did not convert the signal. Not to mention it was not built of quality components. Do not recommend.
Thereasoning is that the only legal use of DD/DTS decoders is for playback oflicensed soundtracks from DVD movies. In your PC, a DVD player software mustdecode your DD/DTS soundtrack, NOT the soundcard. Therefore, as far as Iknow, there is no PCI type sound card which can AC3 signal from S/PDIFinput. Because of the above-mentioned licensing and copyright protections,this is not possible.But Striker7.1 can decode 2ch PCM signal input.
It does exactly what i want it to do which is to convert Digital Fiber Optical (Toslink) to Digital Coaxial (S/PDIF) ..once plugged never looked at it again for more than a year...
I needed this to use to convert the optical to digital coax from my Xbox 360 - works perfectly! Games are always better digital and LOUD!
I tried to convert the digital coax optical out from toshiba tv to digital optical in on sound bar. This converter did not work in sending sound from the tv to the sound bar.
Just plug it in.One cable, two cable, power and I was listening to great sound.As long as your system is configured correctly, this unit works great.I only needed a 3 FT Digital Audio Optical TOSLink Cable to go with it since I had a very long RCA digital cable that came with the speakers.
I need to convert optical output from my HTPC to the coaxial input on my receiver because I have used up its available optical input. This thing converts from the Toslink end to coaxial link end flawlessly. I can confirm receiving Dolby digital 5.1 and DTS sounds without any problem. There might be a slight delay in voice/video sync but it may be due to the media not the converter and it can be easily compensated by m HTPC software (XBMCBuntu).
It looks and feels like a cheap peace of junk, but it works awesome :) Low cost and does what it says, allowed me to hook up another optical port into my surround sound which only had a coax spot available, full signal and surround sound.
Answer: It should.  Mine worked with everything I put through it, including dolby digital 5.1, dts 5.1, and pcm 2.0.  Note that the input is the optical, output is coax.  I think a lot of people complaining it didn't work are trying to use it backwards.
