why collar mic of 9v , do not play sound, if it is put near the collar

[jraju]

I have bought a leading company wireless collar mike with set and it plays fine, if i hold the mic in front of my mouth.
But , when i put it in my collar side or in the buttone hole of the shirt, it did cnot capture the sound .
is there anything , i miss while setting the amplifier cum player , and the mike receiver.
what would have been the cause and what is the solution

If you are getting absolutely no sound at all (which is what your post says) then it is probably a broken wire or bad connector. If you are still getting some sound, but it is very faint, then there are other solutions.

Hi, i said , that if i hold the mike in front of my mouth as normal mic, then there is no problem .
but being a collar mike , i asked this query , why it did not capture the sound when i place the collar mic in collar
There is a receiver attached to the mic of the amplifier speaker, and the receiver set is a mike with a receiver box.
should i change the volume or any other control to get it work
Normally, i saw people holding the collar mic in their shirt buttons down under speaks and the sound is coming
why my mic is not picking up is the query

What brand and model? Some types of mike are like this by design so they don't pick up ambient background sound, especially in noisy environments.

You still did not answer what I asked: are you getting no sound whatsoever when the mic is attached to your collar? If you still get sound, but it is weak, then you have a fairly insensitive mic and need to turn up the transmitter gain.

Hi, dark , the brand name is Ahuja awm520vl
Hi, john, Yes i do not get the sound, when it is placed on my collar , but good sound when i hole it near my mouth.
what is transmitter gain.
i have the max in vollume , not total maximum, as it gives screech sound, in the mic in amplifier speaker.
i have the max in the receiver box attached to the amplilfier speaker.
i have fair volume about 60 percent , in the receiver box attached to the collar mike.
i have placed the mic jack in the mic/ts. There is another jack , mic2.
i have given all the particular

If no sound at all, then it is possible you have some sort of noise gating or squelch control which gates the device on and off depending on the amount of input volume. This is quite common for dictation recording equipment, but I've not seen it on any sort of portable lavalier microphone. If I am correct, then you should be able to hear the mic cut in and out as you talk into it, at close range, and start with a normal voice, but then get quieter and quieter until you are talking in a whisper.

The reviews on that Microphone are not too good. Lots of complaints just like yours.

I looked at an unboxing video and also found a brochure for a similar mic in the same product line. The only things I can suggest are:

1. Make sure the battery in the transmitter is truly fresh. Weak batteries can cause all sorts of problems.

2. Make sure the antenna on the receiver is fully extended and perfectly vertical. This is really important on these types of cheap wireless mics.

3. Play around with both the receiver and transmitter volume controls. Try all four combinations of low and high on both of these knobs.
