HI,

I am looking for a dual RECHARGEABLE VHF MIC SYSTEM--I want to sing and play piano at home -like a 50ft distance max-

The 9V battery changes are a pain and cords are too messy - I presently have the SAMSON 5h Battery unit system.

I have been noticing several of them and most sites do not show specs, so it is impossible to compare , other than by price -- WHAT IS THE MOST IMPORTANT SPEC THAT i SHOULD BE LOOKING FOR and do you have any recs --

I would be satisfied with a DUAL as above with equivalent specs to the SAMSON 5H

I see some for less than $100 , but I Think I have to pay a little more -- ANY help would really be appreciated.

Thanks,,,,,Ralph

My Email is rep@cox.net --Is there a way to find my settings and make some changes ? The faq said go to PROFILE , or preferences , but I cant find it

I'm confused as to why you're looking for a dual mic system. If you're planing to mic your piano with a single wireless vocal mic, I'll stop you right there and warn you that you'll not be happy with the result.

As far as rechargeable wireless mics, unfortunately you're going to find that those systems are made by the cheaper manufacturers. About the best out there in that market, IMO, would be Vocopro. I'm not sure why you specified VHF over UHF but their VHF-3300 would fit the bill based on what you've described.

As far as what you're looking for in microphones, there's a couple things. First and foremost you're looking at frequency response. The wider the range the better and while you don't want a totally flat response you don't want to see any huge spikes at a particular frequency. Another thing that can be very helpful (and is a signature characteristic of the Shure SM58) is proximity effect. Basically what this means is as the sound source comes closer to the mic, the low-end (around 250Hz) comes in a little stronger. It helps make the mic sound a little warmer.

With Wireless microphones another key, and this is a characteristic not a spec, is the companding that is used. In wireless, there is not enough bandwidth to carry the entire dynamic range of the microphone so the signal is companded. Basically it is compressed by the transmitter (reducing the dynamic range) and then expanded at the receiver to try and recover that dynamic range. Unfortunately some quality is lost in this process and this is where better manufactured mics really shine. The only way to really measure this is to listen to the microphones side-by-side and see which one performs better.

OK so that's probably more than you were asking for but I hope it was helpful.

Re: Rechargeable Vhf Cordless Microphone Info

Hi DJ Tony --
I very much appreciate your very helpful reply--Is there a way that I can get a notice of a reply by email --?

MY purpose is to mike my piano with one mike and another for my voice --I could even use a second mike for the piano ( I have a Wireless samson 5h for that ).
picked VHF over UHF as the distance is relatively short and INTEFERENCE is no problem in my area .

I do understand that wired is better,but because of area and furniture, I have to go cordless-

It is kind of difficult to understand specs , let alone even find them on the internet --

I did manage to learn that a major key in the specs might be the SIGNAL/NOISE ratio with the higher db the better- My samson is 100db and it sound s fairly good , so I think I should get at least that ---Do you think that this is a good guide?
base on price and your rec , the VOCOPRO vhf 3300 sounds pretty good , but I can't find any specs on the net -- Not even the S/N which I believe is most important --- I called several sellers and no one knows wht the S/N is --

The 2000AUDIO has the unit that I'm looking for , but the S/N ratio is only 70 and the pris only $70 , so I am suspicious.

Do you know how I can find the S/N of the VCP 3300 or is it just good whatever it is -?

I also appreciate your comment about testing the unit first , but It seems that I have to buy it first via the net ----

Once again , thanks for the info and I would appreciate your opinion on the S/N.

Thank You ,,,,,,Ralph
