So Far So Good
on 16 January 2018
I needed to sort out a way to have stereo headphones connected (for hard of hearing wife) to my surround sound system while still having the main speakers on 5.1 audio. The easy way of using the output jack on the tv wouldn't work as the audio was fed directly from a Raspberry Pi (running KODI, with optical/coax adapter) to the receiver. This adapter looked like it could be the answer. The RPi adapter had both coax and optical outputs, so one was connected to the surround sound receiver, and one connected to this D to A adapter. A quick test using heaphones directly connected to the L/R line out RCA connectors using the supplied adapter cable and it worked almost perfectly, but not loud enough for my purpose. There is a tiny difference in the processing time between this device and my surround sound receiver, but not enough to cause a problem. I had the output set to 2.1 so the dialogue would be present on the L/R outputs. I tried with media having DTS and Dolby Digital audio tracks, and both worked perfectly. I added a 5m headphone lead and a home made headphone amplifier and hey presto all working LOUD and CLEAR! I intend to use the second optical input to take the output from a Humax Freeview PVR so she can have the tv sound on her headphones too. Not tried this yet but sure it will work as some of the files I was testing it with were recorded on the Humax. I got the RCA output version to make it easier to try with the output set to 5.1 and use only the centre channel to feed the headphones. This may be ok most of the time as it is mainly the dialogue that needs to be fed to the headphones, although sometimes speech does come from the sides on 5.1 audio. The front panel LEDs are green on the one I was sent. Brightness is not an issue as the unit is tucked away under a chest of drawers.
Can't comment on reliability yet.
The item arrived quickly, and safely packed. The parcel tracking gave me a map of where the driver was so I knew within minutes when it was going to arrive.
