Wireless Mics and preamp?

    (I'm posting this for a friend)...

    "I purchased a new VocoPro VHF-3300 wireless mics.


    Would like to connect it to my stereo system to to have a faux karaoke for our living room so that mu wife and I can practice a little singing together.

    The problem is of course the mics have 1/4” male plug and the stereo system has 1/8” female plugs.

    Will a pre-amp be the bridge that works between the mics to the stereo? For example I have an Audio Buddy pre-amp. Would that work?

    In other words, will I be able to connect mics (wireless system has two mics) into the pre-amp and then will I be able to connect pre-amp to the stereo system - if so what would the cable from the Pre-amp to the stereo need to be?

    The Audio Buddy features/specs are:
    2-channel mic/instrument preamp mic ins; 1/4” instrument ins; balanced 1/4” outs

    You should be able to do this without involving the Audio Buddy.

    Use a standard "insert cable" (stereo 1/4" plug to 2x mono 1/4" plugs) plus a stereo 1/4" jack socket to 1/8" stereo plug adaptor. Route the output of each radio microphone into the L and R channels of your stereo system. Switch the amp to "mono" if you want the two mics to come out of both speakers.

    It's likely that the audio levels will be just about OK without having to use attenuators, as most radio mic receivers (like this one) have output level controls on them that you can turn quite low.

    I have to warn you not to expect too much in the way of audio quality with this radio mic system.

    Well, would the pre-amp boost the mic signal level, thus improving the quality? Or would there be an issue with the pre-amp being connected to a stereo (i.e. could it damage the system)? Thanks.

    The wireless receiver takes the place of a pre-amp. The problem here is that the signal levels could be too large for your domestic stereo inputs and may need attenuation, but they will not need "boosting" through an additional pre-amp. There is no physical danger to the equipment from having levels too large - you may get distortion, and, if so, will have to consider fitting attenuators.

    The quality problem is with the radio mic system and does not have anything to do with output signal level.
