HELP a newbie! adding MIC to HOME THEATER AVR with a amplifier/mixer

[Neogoro]

Hi everyone,

I am amazed at the existence of this forum. I am excited to share my virgin post for help.

I just moved into a house with a home theater, and it is setup with a A) SONY STR-DN1080 ARC out to the B) EPSON projector. Everything works.

In my previous house, I setup an entertainment center with a karaoke system that uses:
1) Digital Amplifier/Mixer that acts kind of like a receiver
2) UHF wireless MIC station
3) a Karaoke source computer that basically is a computer with Karaoke interface installed and songs stored

3) would HDMI into 1) and 2) would MIC into 1) and 1) would eARC out to the TV. Everything works.

----

I am trying to figure out how to setup this system in the new house. I tried multiple configurations but cannot get the wireless microphone to work. The video/audio is working from 3) (Karaoke source).

Configuration A
3) would go into 1) and 1) would output to A)open input like a SAT/CATV HDMI port.
Analogue Red/White cable would go from 3) output into 1) input, and then another R/W cable from 1) output to A) SAT/CATV Audio Input
2) would go into 1)

--> results in audio/video, but no microphone

Configuration B
3) would go into A) open input SAT/CAT HDMI port
Analogue Red/White cable would go from 3) output into 1) input, and then another R/W cable from 1) output to A) SAT/CATV Audio Input
2) would go into 1)

Attached are the pictures of the equipment A), 1), 2),and 3)

Audioholics gods please help!

Config A sounds like it should work but chances are that when using an HDMI input, the receiver is going to default to using audio from the HDMI cable. If the mic is only mixing to the stereo RCA line, you'd need to configure that input on the receiver to use the relevant 2 ch input you plugged in from the mixer.

If the mic is supposed to be mixing into the HDMI sound signal as well, then I'm not sure why you don't hear it. Possibly a setting on the mixer in that case. You wouldn't need the RCAs at all then.

Thanks dolynick. It’s great to hear you suggesting that I was in the right direction.

yes, I also thought it didn’t need RCA but because there was no sound I tried to see if that would work.

when I had the karaoke setup in the old house it didn’t need the RCA. Everything was HDMI ARC

I did notice on the A) AVR , the HDMI input ports some had a ( audio in) next to it and the one I used “SAT/CATV” didn’t . I will give that a try and also see if there’s any setting on the mixer I need to adjust…

And---- negative. Still doesn't work.

Have you tested the mic by itself?

At this point I would try connecting it just to an RCA input on the AVR (or any other basic amp and speaker setup) and make sure the mixer is receiving/outputting any mic audio at all.

You have three points of possible failure up that chain. Wireless mic not transmitting (batteries?). Wireless receiver not outputting and Mixer not passing an audible signal out from the Mic input (gain settings?).

Your original post says that configuration A results in audio/video but no mic. If you have both audio and video from the receiver then you can eliminate that as the problem, and as suggested, remove the RCA audio cable if it's not needed. If it's only the mic that is not working, then start with the source and work your way down. You need to confirm that the mic is connecting and you are getting audio out from the mic station. (Can the mic station be connected to an audio input on the Sony for testing?) Then make sure everything is working on the mixer.

Interesting gear. What is the model number of that mixer? Karaoke computer?
