There are no power singers on this forum - NONE! I see lots of power singers on America's Got Talent and BGT, but not on the Sythzone.

I've used both the TC Helicon Harmony-M and the VH2 on my S-950. When properly tuned, the VH2 worked equally as well, no drop outs for someone that does not use the pull-away effect (proximity effect), and utilizes vocal control instead. It really doesn't make a bit of difference if you use a headset mic or handheld mic. I have achieved equal results with both types of mics. Keep in mind that if you use the proximity effect, you pull the mic out of effective signal range, which would, obviously produce dropouts with any vocal processor. They all, including the best TC Helicon, need adequate signal strength in order to process the signal. Maybe the gain on the TC is set higher by default than the VH2, but the VH2 can be set to any level you wish. However, when the gain is increased, so is the possibility of feedback.

I know several performers that use the proximity effect, but none are what I consider power singers. This is not to say they are not good singers, but when they attempt to hit notes that are obviously out of their vocal range, they tend to pull that mic away and hope that no-one notices they cannot hit that particular note.

Vocal control takes a bit more concentration and training. I learned it many years ago when I was a newscaster for a local radio station. You had to be able to place emphasis on certain words of a news story while maintaining the same audio level. Under these circumstances, the proximity effective would be totally useless.

Just my .02 cents worth,
