Weak audio static uc2-ub handheld

Feedback is caused by having the volume up too high or being too close to the speakers. Turn mic down a bit, feedback goes away.

Better speakers and mic will help.

This is often caused when an earth wire touches a channel wire, check all your connections, especially those to the cartridge.

Bose is proprietary. It could be electronic parts that are called capacitors.

Pioneer deh 15 ub does not have intial setup option and my music plays bass and hardly and vocals at a low state.I need it to say rear rear

Make sure the switch is set to "mic/line" and not "guitar"
Your input level will be set by the "input L" or "input R" knob, depending on which side you are using. Start with them all the way down and then sing into the mic, turning them up until you get a signal about halfway up the bar in Cubase. That should give you plenty of headroom for clean vocals.
It may be difficult to get a good sound if you have one of those cheap mics that has a "1/4" jack instead of a 3-pin XLR jack. You might want to go to your local music/pro audio store and invest in a "condenser" microphone, which is good for vocals in the studio.

Is your wireless router near the computer, it can cause itermodulation in your sound card. Cell phones will do the same thing.

Since you didn't list the brand name or model - I can only give some generic help.

The problem sounds like a "sound profile" mismatch on a system that has some sort of surround audio speaker set up. One example of a mismatch is (there are plenty of other, too): Your itouch has only a left and right (stereo) output and you might have the system trying provide some sort of dolby digital effect (theater, adventure movie, etc.) applied to it. Since it is lacking the expected input signal (center, rear left & right) - some audio info is lost.

Solution: Nothing is broken - you just need to cycle through the sound profiles on the system to locate the the one that restores the lost audio signals. Note which one is currently selected before starting - so you can return to it when done. You'll have to change the sound profile whenever selecting the itouch sound source.

If this is too generic - reply with your shelf system manufacturer's name and model number. Then we can dig deeper.

I hope this was helpful!

Here is some very general info, however for more detailed info, I need more information on what your using it for. Speechs, Play, Vocals, Bands? Inside or Outside venue?

For Vocals you should have no problems with a Wireless Handheld SM58, they work over a large range, however still have a limit. Make sure the receivers are always close enough to the mics to hold a reliable connection.

Wireless Lapel Mics (Clip-on) are more troublesome, as they are generally consenser mics which are more susceptible to feedback. You also need to place them somewhere in range of the person's mouth, whist avoiding placing somewhere where you will get alot of fabric movement whist moving around, or you will hear that very loudly FOH. You also need to deal with body-packs and wires.

Leturn mics are generally easier to deal with than Lapel, however again are Condenser and more feedback prone.

I would reccomend the SM58 where possible, as it is much easier to work with, and you are more likely to get a better sound with less work.

Check and make sure you hook up the speaker wires correctly to the stereo, they are color coded. This unit does not have manual equalizer settings.
