Question: Does it come with pwr supply
Document: Received item today. Power supply is defective and would not work. Tested with meter and no power. Sending back to Amazon.
Using this tiny adapter box, I am happy that it solved the audio problem.The adapter looks solid in a black metal box. It comes with its own power supply. The installation is very straightforward.
IT does the job but you have to work with your TV settings or else certain audio does not come through and there is a high pitch hummm
Purchased to connect my digital tv to a legacy amplifier. The function light didn't even come on when plugged in to power . Junk!
The item did not work on my TV it did not come with the cable to connect my TV and i had to go buy it. I have requested a refund. Let me know what needs to be done? I have already returned the item.
i got this item as a replacement for one i got before that was the wrong item. this did not come in a box, the unit had obviously been opened before, you could see that the screw had been removed and something was rattling around inside it. the unit did not work. so we were sent a returned item and charged as if it were new.
I needed this to be able to use my Turtle Beach X32 headset for my Xbox 360 on my Xbox One and it works just how I need it to. The audio quality is good and it is very easy to set up. It does not come with a optical audio cable so I had to purchase that separately.
I used this because I needed my Apple tv, which only has optical out, to connect to my old amplifier, which doesn't have that input. It comes with an adapter that plugs into the wall, but you can easily use a USB 5V adapter to supply power if that is more convenient.I don't care for 5.1 or 7.1 sound, so this is a perfect solution.
You are most likely to receive the product matching the review if order one that is FULFILLED BY AMAZON. This is because sellers will generally send in large quantities to the Amazon warehouse at one time.------------4/14 Seller: Century Accessory - Ordered by us. Bulk packaging bubble wrap. Includes Converter, Power Supply and Instructions. Tested fine.
I got this adapter so I could use my Turtle Beach P11's with my PS4 and have full audio quality until they add wireless support to the system. The P11's work for communicating to teammates and you can also get the audio to come through them without this adapter, but the audio was too quiet for me regarding game sound that way so I opted for this adapter instead, and it sounds much better.
Answer: Yes, it comes with an AC adapter.
