No comments since May 22nd. What's up Vitaliy?

I've been using the internal mics recently on an interview (there was no wifi there at all), i'll post it as soon as it gets edited.

It could be interesting.
How is the level? As I don't hear much in the headphones in Mid, and later it is noisy.

But they are extremely (!!) hard to get off, in fact, i think it's impossible!.

I think that you need to glue some small thing (like bump) to them, so you'll have thing to hold, after this it'll be easy.

just up the Mic_vol on the receiver?

Yep.

Is it on both channels then, or one only?

As I remember, on both.

Some initial opinion.

Good things.

• This thing looks like next gen budget solution. Due to high contrast oled screens and
• Very easy to setup. You leave reciever at autoscan, and set channel at transmitter. It locks almost instantly.
• Has build in mikes both or transmitter and reciever. Two mikes on transmitter and one on reciever.
• Mike on reciever is facing you. So, ideally you can make interview using only this thing.
• Mike on reciever can be mixed with remote signal.
• Looks like it is really digital (I mean transmission), as I see no noise induced by transmussion.
• Big advantage that it is stereo transmitter.

All below is preliminary due to 5 minute test using one mike (and build in mikes) and two headphones only. I used Panasonic stereo electret mike.

Problems:

• Do not like battery covers, as they are very hard to get off by hand and placed weirdly.
• To hear mike sound in headphones clearly you need to push mic boost to high and volume almost to max.
  It requires more experiments and I'll make recording to external source to check levels.
• Such pushing result in noise. Not good. Looks like almost perfect white noise. It looks like noise source are mic preamps.

So, for now I am not recommending getting it.

Hello, Vitaly. Did you received the microphone?

I'm curious about your review. I found this micro in Dealextreme a few days ago and, well, I'm thinking to buy one.

Good day Vitaliy, Have you received the parcel finally? What is your opinion about ROWA wireless system?

Is the mic coming from China to Russia on the back of a camel ? Its amazing how much time DX is taking for a country that shares a border with China.

I ordered one too, made a login here just to update with infos as soon I got it. I think it's promissing, but I dont believe it comes with a lav mic, so, any recommendation for me?

@Gethinc

Nope. Not yet.

I've discounted the use of wireless before seeing this - either too expensive or potentially too crap. My limited experience with lav mics dates from 15 years ago, if a half decent mic is $50-100 its still in my price range. If they're more like $300, I may just wait a wee while.

any suggestions for lavelier mics to go with this?

There are more digital wireless broadcast systems, like ZaxCom, AudioLTD or other $ 2000 + solutions. But these are in the 400-900 MHz range, meant for broadcast wireless systems. As are the Shure PGXD system and the Lectrosonics systems.

Those - 10x more expensive - systems are not in the 2,4 GHz Bluetooth, Wifi (and microwave!) frequency range, like the Rowa and Line 6 systems. This frequency is very crowded and also more directional-sensitive.

I guess sound quality of these Rowa's will be good, and it looks like you can power them with 5V from your rig, and there is a separate headphones out as well as line out (volume adjustable to GH2 input levels?). So at first sight this looks very good for a set that costs less then $ 200.

So it could be a great alternative for those expensive TxRx sets or even the current $500/600 Sennheiser sets. At this price, the real interesting thing is if the wireless reception is good enough for avarage use. Do you know if those Line 6 owners use their system at run&gun location work, or only fixed positions? Both are 2.4 GHz digital diversity systems so I guess they'll hold up the same? It would be interesting, as I am looking for an extra set as well.

If I understand correct the cheaper 400-900 MHz systems like Sennheiser G3, Sony U1 and Audio Technica 1800 are not digital? Did anyone test the (also cheap!) Samson Airline Micro system?

Its analog over a 2.4GHz spectrum. Lectrosonics is the only with with a digital transmission. They conver the analog signal to digital before sending it out and decode it on the other end,

Can you tell me source of your information?
None of the specifications say this. Their home page has "complete digital wireless stereo microphone system"
Same on the cases "digital wireless system". Looking at 86db SNR and 80db stereo separation it also looks like digital specs. Of course it can be not entirely true, we'll see :-)

Lectrosonics is the only with with a digital transmission.

It is also wrong. As Line 6 systems exist for years that are very advanched digital systems working in same 2.4GHz range.

I would be curious about the reviews. ALL the cheap wireless mics I tried sucked so far. Transmission is not digital. Its analog over a 2.4GHz spectrum. Lectrosonics is the only with with a digital transmission. They conver the analog signal to digital before sending it out and decode it on the other end,
