    The power Output is 10Mw (whatever that means (I guess mW is what they meant), which is lower than the 50mW in the original post. In my head that means a weaker signal, but I guess we'll have to wait until someone tests it.

    The audio technica sounds great, but it is also way more expensive.

    @arum

    It all looks them same, just with highly inflated prices.

  • arumarum

    Super old topic, but the dslrfilmnoob found what looks like a newer version of this and other people may be interested. No sound quality test, but after listening to the quality of the system tested by Ty Ford, I am really curious about this kind of technology.

    power on the plug is 2,85V. should work with those cheap 1.5-10V electred lavaliers on ebay. Buying now... I'll get back if it works

  • Vitaliy_KiselevVitaliy_Kiselev

    Btw, Rowa seems to be back

    Case is different now.

    @DirkVoorhoeve

    I think that you need some battery power for them.

    I used noname lavalier and panasonic stereo lavalier, both are not good (using ROWA).

    Interesting idea cn be to use small dynamic cardioid mikes.

  • DirkVoorhoeveDirkVoorhoeve

    @Vitaliy_Kiselev could you maybe tell me which ones you use as both my DPA and the newly bought Sennheiser ME4 are electred mics and both don't work...

  • Vitaliy_KiselevVitaliy_Kiselev

    mic input does only have very little power on it, so it doesn't work with my DPA. @Vitaliy_Kiselev which lavalier mic do you use?

    It can be the problem.

    I used only electred mikes with it, ones without their own power.

  • archp2008archp2008

    As for me I decided on ordering a Zoom H1 recorder and a $20 lav to connect to it. I came to the conclusion that the quality of the audio was more important and I wanted to avoid the limitations of the built-in recorder of my T2i. If I had had $1000 plus to invest, a top quality wireless unit would have definitely been considered. I doubt if anyone who reads this thread now will order this particular unit.

  • DirkVoorhoeveDirkVoorhoeve

    just been using it a bit more:

    • I found that the automatic channel selection doesnt work well but had a very good reception when I set both the transmitter and receiver to manual;
    • The line input of the transmitter can't take a normal line (-10 dBV) output. It has to be attenuated a bit to work;
    • Both the transmitter and the receiver work about 3 hours on one battery (it is about 1 bar per hour on the battery indicators). The nice thing is that you can charge the battery inside of the receiver with USB from your battery pinch, so you can exchange batteries every three hours.
    • The two internal mics are not that good. Maybe nice for spying but not for recording. Also very sensitive to wind-noise.

    mic input does only have very little power on it, so it doesn't work with my DPA. @Vitaliy_Kiselev which lavalier mic do you use?

  • archp2008archp2008

    I'm wondering if fabioc concurs with Vitaliy that these units may not be worth getting.

  • Vitaliy_KiselevVitaliy_Kiselev

    @disneytoy

    Very bad idea, as Wi-Fi is power hungry, dropounts friendly and made for completely different things.

    Really good idea must be multiple channels digital transmitter and reciever, so receiver can choose channels without dropped data. But such thing is not easy to develop. And this market is really tiny.

  • disneytoydisneytoy

    With super cheap and small wifi chips, wouldn't it be easy for someone to make a wifi based wireless mic? And you could choose to record on an Ipad, Iphone, Notebook or a wifi enabled Zoom?

    @archp2008

    DX.com is site of DealExtreme, that this dxebay shit site is I have no idea.

    So, if you want to get this stuff, use some known site.

  • archp2008archp2008

    Its easy to misunderstand when we are not talking to people face to face and when some of us share different languages. I would have been very hesitant to order from that "DX" Ebay site. My guess is it's probably some kind of hacked site or scam.

  • RamboRambo

    Looks very suspicious to me trading off the ebay name and logo...hehe. Actually, sticks out a mile :-)

  • Vitaliy_KiselevVitaliy_Kiselev

    @archp2008

    No, under site owner I mean that dxebay.com look suspicious :-)

  • archp2008archp2008

    Sorry, Vitaliy I didn't know you were the site owner. I just hit upon the thread for the first time and replied at once. I thought you were just one of a group of participants in this specific thread, except that you knew more about this particular system and were going to say more about it. Later I looked around the site and noticed that you were the top poster. Great site. Great idea. I don't have a lot of money to spend on a microphone system. With no review, it doesn't look like this one is going to be on my short list, more likely a wired stereo lavaliere.

  • Vitaliy_KiselevVitaliy_Kiselev

    @archp2008

    Yes, of course.

    It is just good to understand who is owner of this site.

  • archp2008archp2008

    Can't tell if this is the same system or not? http://www.dxebay.com/10quot-lcd-24ghz-50mw-stereo-wireless-microphone-system-transmitter-receiver-set-for-camera-p-54370.html

  • archp2008archp2008

    They are available elsewhere at higher prices including from Gadgetinfinity in Hong Kong on Ebay. It's too bad that more sellers including Dealextreme don't work out a more comprehensive review system where buyers could write in about their personal experience with specific products such as Newegg and Amazon do now. A Dealextreme representative told me they expect more of the Rowa systems within the next week or so. No way to know whether or not the price will be as low as originally, though.

  • peternappeternap

    @archp2008 I was looking at them too but they are sold out. I'm sure Vitaliy will give his opinion when he has time.

  • archp2008archp2008

    Hi Vitaliy. Thanks for the reply. It was a loud cry but not intended to be obnoxious, I hope. I was planning to purchase one of those Rowa systems for my T2i but couldn't find a single review out there, so you seem to be my only hope. I notice now that you aren't recommending it but I was anticipating more experimentation with recording as you mentioned this past spring.

  • Vitaliy_KiselevVitaliy_Kiselev

    What's up Vitaliy?

    Any specific reason of this loud cry?
