I just know the basics about audio and am looking at Audio-Technica's selection of wireless lav systems. On the B&H site, they have 6 AT wireless systems for the same price. I was wondering what the difference between them is and why they all cost the same.

Here are the mics: http://www.bhphotovideo.com/bnh/controller/home?A=search&Q=&b=81&mnp=0.0&mxp=0.0&shs=&ci=9450&ac=&Submit.x=19&Submit.y=5&Submit=Go


Basically, the differences between them are this:

T- Transmitter
R- Receiver
M- Microphone

(1)
T- ATW-R100x
R- ATW-T101x
M- MT830cT5

(2)
T- ATW-R100x
R- ATW-T101x
M- MT831cT5

(3)
T- ATWT101
R- ATWR100
M- No Microphone
(728.125 to 740.500 MHz)

(4)
T- ATWT101X
R- ATWR100X
M- No Microphone
(656.125 to 668.500 MHz)

(5)
T- ATWT101
R- ATWR100
M- MT830cT5

(6)
T- ATWT101
R- ATWR100
M- AT831cT5



Is there a difference between the ATWT101 and the ATWT101X? Are the systems that don't include mics higher quality?

Sorry if these are total n00b questions. Audio is definitely not my field.

Thanks in advance,

Thanks, Bill! I noticed that a few hours after posting my original question. Still one other question, though:

The packages without mics have the exact same specs on B&H as the ones that do include mics. Why is there no price difference?

I'm hoping to buy one of these when I get my paycheque so if anyone had some insight into this, that would be awesome. If not, I'll try giving AT a call. As of right now, I'm leaning toward the package that comes with the MT831 mic.

Thanks in advance for any help,
