  1. Hi there,

    I've just got a wireless USB mic to upgrade my PC karaoke set up, but i'm suffering from that old chestnut, mic sound out of one speaker only.

    My wired USB mics are audible through both speakers by default, as they appear to come through as mono (1 channel shown in properties). The wireless mic though, shows as 2 channel sound only, under advanced settings, suggesting the computer is converting it to a stereo input, thus one channel is empty.

    I've tried tweaking all settings, and lots of googling, and can't figure out how to get mic sound from right and left.

    Can anyone help please?

    Windows 7/Realtek HD audio/wireless mic receiver connected to PC rear panel via USB and pink mic socket/ amp audio cable from green line out jack to red and white dual input on amp.

  2. Try the USB receiver output connected directly to the amp, turn the volume down first. If you get the same result, try another 3,5mm to RCA cable.

  3. Thanks nic, i've already swapped the cable, and i like the amp idea, but i don't think it'll work on this one, as there's only a headphone jack?

  4. You have a mono mic plugged into a stereo jack?

  5. Ok, got the obvious out of the way, the cable is not the issue. BTW, that's a nice little amp. It has a 3.5mm input where you should be able to plug the mic in as you do with the pink input on the computer. More details on the mic itself would be helpful as well. Just guessing here, but I don't think you're supposed to have the mic plugged in the pink input. I think the audio goes through the USB port.

    It has to be what jagabo says, otherwise it would be a mono mix. AKA, two channel mono.

  7. This USB mic has a 3.5 Jack which the manual says to put in the pink input, but neither this nor any other input produce mono mix, which is my goal. It is a cracking little amp, and I hope you're right about that input nic!, I'll let you know.

    Pink jack is mono - stereo jack is required due of MIC - MIC have small amplifier that need to be powered - that's why stereo jack and 3 cables are required for Mono MIC, later mixer in sound chip will do Mono mixing (MIC on R + L) - in case of wireless MIC everything is possible even being Mono and using Left (or Right) channel only from 2 possible channels (i.e. MIC is wired to only one channel).

    I would go to advanced mixer setting and i will set above input "Balance" co mix correctly Mono to L+R.

  9. Bad news, the 3.5 socket on the amp produces only very quiet audio from the left speaker only.

    There has to be a way to create a mono mix of this signal!

    Thanks pandy, but could you clarify on what i need to do to the balance settings?

    Balance is used to adjust ratio (distribution of signal) between channels - so if you have signal only in left and you want signal mono (both channels), to redirect it to right you need to balance ratio in a way where 50% of signals stay in left and 50% is feed to the right channel.

    3.5 socket on amp may be like line in on the PC (blue jack) - this can be stereo signal without power line (pink jack have +5V DC power to supply MIC amplifier) - consider to use dynamic MIC (less popular than capacity - electret commonly used nowadays) .

    Just ordered this, from the reviews it should do what i need!
    Yes, if MIC doesn't need power supply.

    The low level was expected, but it does confirm that the 3.5mm mic output is a mono signal (as it should be and as Pandy explained). The only question then is how is it that Windows says it's a 2 channel mic? The only possible answer is some information is coming from the USB connection. If you have a mobile charger with a USB port try plugging the receiver in it instead of the computer's and leave the pink connector plugged in the PC. Also, was there any software or drivers with that mic (or were you instructed to download something)?

    I don't see how this will work, you can't use it on the mic output and if you plug it into the PC green connector and plug the 3.5mm to RCA cable into it, you will still only have sound out of the left side only. If you connect this y cable to the left RCA of the 3.5mm to RCA cable you will get sound out of both speakers. It's a quick and dirty fix and doesn't address the real issue. It would take a model number for the mic so we can stop guessing.

  13. Talking about guessing, I meant to mention that you should look at your karaoke software mic selection panel and see if you don't have another input other than from the Realtek sound card, it might say something about USB. If you do it's probably the 2 channel mic receiver outputting through USB; select that one and that will solve your problem.

  14. Thanks all, i'm gonna run with pandy's comment,

    Yes, if MIC doesn't need power supply.

    This mic has its own usb power source.
