PROZORPROZOR DAC Converter 192kHz Digital to Analog Converter Digital Optical Toslink Coaxial to RCA L/R 3.5mm Analog Stereo Audio Converter Adapter with 1 m/3 ft Optical Cable for HDTV DVD PS3/4

Easy to connect. Works perfectly.

I needed this because I have a Samsung TV which has awful audio. I have a Bose home speaker which has Bluetooth, but there are lip-sync issues, so the only other supported option was to use the optical output from the TV, and use this converter box to go into the analog 'Aux In' connection on the Bose device.It works fine, but you'll have to set the TV to always output in 'PCM' mode, otherwise the audio will disappear when watching certain programs using a different encoding. The audio quality is pretty reasonable (you wouldn't expect top Hi-Fi from such an adapter, but it's certainly way better than listening through the built-in speaker inside most TVs).A slight issue is that the audio level is no longer adjustable from the TV remote control, but that's not a fault of the adapter.The adapter is well built, in a folded metal enclosure. The attached photo shows what is inside, for those curious about what integrated circuits are used.I liked that the device comes with an optical cable, and a power supply cable (USB Type A). Many TVs have a USB socket, so that can provide the power. Note that the product does not come with any analog audio cable. You'll have to purchase a phono (RCA) cable separately.

Seems to do a good job at converting digital to analogue. However, unable to adjust the volume using the TV sound output. This might be an issue with LG audio output.

Sound output is low compared to other sources when wired to my Denon M37 receiver. However, I had a headphone amplifier on hand, and the signal goes there First, then to the Denon. I now have variable gain. This sight drawback might not be due to this item. Could be th TV.

Got this little gizmo, because the CD player in my Panasonic SA-AKX52 hi fii had packed up. My choice was try and repair or replace the CD player, buy a separate player, for which I would need another electric socket or find a way to get my Sony BDPS4100 Smart 3D Blu-ray Disc Player to play through my non smart hi-fi so I could use that to listen to CDs.Problem was, my BD player, only had a digital coaxial output and my LG TV only had one SPDIF/Toslink digital output. My hi-fi had neither of these as inputs.I already had my Tivo box connected to my hi-fi by a scart multi connector, which also converted the audio, to standard stereo audio phono/RCA plugs, which then connected to the hi-fi.The blu ray player and TiVo were connected to the LG TV by HDMI leads.This little box solved and simplified, the whole mess.It comes with two leads one USB to DC barrel type connector cable and one optical (also known as SPDIF or Toslink) cable.What you do is plug the USB lead into a USB socket on your TV. (If your TV doesn't have one, you will have to get a separate one that plugs into the mains or use a USB socket from another device such as a play station, lap top etc.) The USB supplies the power (5 volts) to the unit. A red light will come on, telling you the unit is now receiving power.Then you plug the the SPDIF/Toslink lead into your TV and the other end into the Prozor DAC unit.. Then using two standard audio phono/RCA leads, connect the phono sockets on the unit, to the phono/RCA /Aux IN sockets on your hi-fi.(These phono/RCA leads DON'T come with the unit, you have to supply these yourself)That's it... Now any digital audio, that is coming into your TV from HDMI connectors or other inputs, will be output to the unit from your TV converted to analogue and sent to your non-digital hifi..Before, when I had my TiVo connected to the hi-fi by scart, when I used my blu ray player, I had to use my less than ideal TV speakers to listen to the audio on films, as the blu ray player had no scart or phono out sockets. Now I can use my hi-fi speakers if I want to.I am only using the SPDIF/Toslink socket on the unit, to connect to my TV and hence Blu Ray player and TiVo box, to my hi-fi. It also has a digital coaxial socket, so if I wished, I could connect my blu ray or any other device with a coaxial digital out socket, directly to the unit and hence to the non-smart analogue hi-fi if I wanted to.It has an autosense input selection, which prioritise the SPDIF/Toslink connectio, so this must be disabled/disconnected to use the digital coaxial one.Very pleased with this device. Unit itself, is sturdy and well made, leads are not particularly long (not an issue if you are plugging them both into the same TV) The SPDIF/Toslink lead, is maybe not the sturdiest I have ever seen but if you are not going to be plugging and unplugging it a lot, then that shouldn't be an issue.With digital leads, they either work or they don't, they are not like analogue leads where you sometimes get a bit of power through but not ALL of it. with digital leads you get ALL or NONE.These worked right away no problems whatsoever. Sound quality, seems very good. I played various sources, through the unit. CD, mp3s from USB stick, SD card, from USB converter,YouTube etc and they all worked. The levels seemed fairly consistent, going to the hi-fi and of course you control the main volume from that volume control, there is no volume control on the unit.All in all very pleased with this little device.

Works very well taking the optical sound output from a TV to an older amplifier as speaker system. Excellent value, solidly built. Very good service too.Recommended.

Was really looking forward to receiving this as was exactly what I needed to set-up a speaker to my LG TV with only Optical/TOS output for audio. Unfortunately once I had everything set-up and TV settings correcting adjusted etc I could not get any sound out whatsoever so went through every step of set/up, double checking everything one by one to try and figure out what the problem was. I even tried all recommended troubleshooting methods as per included manual. Was only when I replaced the included Optical cable with a brand new, more superior quality one did I finally get the volume to work!Be aware the included cable is very poor quality and you may be out extra costs needing to purchase a new one like I had to!

It seems that it should be ok with Samsung TV, but not for LG.One LG TV, you get one sound level and that's it: no way to adjust the sound coming out from the converter... unless you add another device of course... It would have been good that was put a bit clearer in the description.
