Hi, I am new to the forum, first question.
I recently purchased an LG OLED C2 tv.
OLED65C2PUA. I am having difficulties in connecting our Vocopro karaoke system. Karaoke system VocoPro DA-8909RV is more powerful than my Sony STR-DN1030.
Tv has hdmi ports and 1 earc that is connected to my stereo av receiver. It also has an optical port and a couple usb ports.
Vocopro system has all red/white connections.
I tried using an optical cable out of tv to converter Box to red/white connection to karaoke system. I get no sound.
the Sony receiver does have a pre-out red/white connection but not sure if I can connect it to my karaoke system?
Any help would be useful.
Your Karaoke system is analog, and not digital. The pre-outs from you receiver are sub only. You can not use those to connect to the Karaoke system.
You should be able to get sound from the TV to the Karaoke, but not from the karaoke to the TV.
You need to turn on the optical output of your TV in the set up menu under audio settings. I don't know what converter you have, but I suspect it requires PCM. If that does not work, then set the audio out setting on the TV to Auto instead of PCM
What speakers are you using for Karaoke? For Karaoke you must use pro type PA speakers. You will blow up domestic speakers.
If you are connecting the TV to your receiver via ARC, there will be a problem, as you will have to keep going into the menu of the TV and into the Audio settings and switch it between HDMI and optical.
This is not going to be a handy system, but really awkward. The reason is that we are passed the analog sunset, and for reasons of digital rights management, there is a forcing of HDMI.
So the Karaoke unit is not much use, as from what I can find, it has no HDMI output port to connect it to a TV, which is now mandatory.
Just for future reference, it is a boat load of work to find out what equipment you have and what it is. None of us have the vast myriad of equipment available in out heads. So when requesting help, you need to link to the manuals and specifications of all the equipment you are using and connecting.
Equipment is now very complex, and I think you have equipment well beyond your level of understanding.
