Wireless Tapping Risk (security) & Signal Strength: XD-V30L

Hi, I'm going to buy XD-V30L, and have 2 important questions.

I am going to use it in a conferece or in a lecture room.

Therefore I would not want to have my talk "tapped" and/or "listened to" by a third-person's set of same XD-V30L.


(Question 1)

Suppose my transmitter & receiver are working properly in a pairing condition on the Channel-1.

Can a third-person's receiver (another set of XD-V30L), if set on the same Channel-1, catch my signal and listen to (or tap) my talk?

-- Put simply, Can two reveivers catch and listen to the single same transmitter?


(Question 2)

If the answer for the question 1 is YES, I need to set the singnal power of my transmitter as lower as possible in order to avoid being tapped somewhere else.

What tips would you kindly advise?

-- eg. adjust the signal power (how?), take off the antenna (possible?), cover the transmitter all over with a certain material, use weaker batteries, etc.


Thank you very much for your kind attention.

    #1 Yes

     

    #2 You could cover the antenna but it would be very tricky.  You'd be better off to use XD-V70 and switch it to "low power" mode (not possible on V30)

      Thank you.

      Will you answer 3 follow-up questions?

       

      1) Is the signal of V70 (set at the low power mode) weaker than V30?

      The signal of V70 is originally three times as stronger as V30, I understand.


      2) Does line6 offer a product that satisfies my needs -- to have a secured wireless connection valid ONLY between one transmitter & one receiver?

      You once answered in the forum titled "about Digital microphone.."(thred #59227), you answered that the signal is encrypted with channel hopping.

      But if someone uses another receiver of the same model and tap the conversation, the encryption does not mean anything, I'm afraid...


      3) My practical concern is then how I can attenuate the singnal power of V30.

      Do you have any ideas to try?


      Thank you.

        1) The output of both the V70 and V30 transmitters is 10 mW.  Switching to low power mode in the V70 backs it down by 5dB which gives you about 3.6 mW

         

        2) No ... what you are asking for is an encrypted signal that you can generate a single key.  That will put you in the $2k-3K range for available products.

         

        3)  Practically, no ... you will not be able to affect the output.  The simplest and lowest cost solution would be to go with V70.

         

         

        At least with XD-V digital wireless the only thing that can pick you up is another XD-V receiver.  With other systems and simple scanner can find you.

      ... and probably use something other than the default channel 1 (not really a major obstacle if someone is intentionally listening in, but ought to minimize accidental overlap).
