OT: wireless relay for medium-HiFi stereo

A friend of mine plays in a couple of pub bands, and I'm making some you-tube type videos for him from live performances. I've been taking audio from the line out of his mixing desk and recording it on a small Tascam recorder (I've had to make up a little attenuator to match the levels, but otherwise no problem).



But it would be easier if I had the recorder at my filming position, and it is not usually practicable to run wires across a pub.



I thought it would be easy to find a reasonably priced audio streaming system. Don't need much range so Bluetooth should be OK, although I recognise that WiFi might be better. Ideally a battery powered transmitter that will take two channels at "line" levels, and a similar battery receiver. Latency shouldn't be a big issue as I need to synch the audio and video anyway. I don't want to pay "professional" kit prices, I suppose I might go up to £100, but given that the Tascam DR05 was under £100, I can't help thinking I should be able to do it cheaper.



I've been Googling but so far am struggling to find something which looks quite right.



Comments, suggestions, recommendations most welcome.


Doesn't have to be digital, of course: could be UHF as used for older wireless mikes.

If you're filming stuff, a decent radio mic will always find uses. A TX pack one that can also take line level?

No idea if it's suitable, but Amazon seem to have D-Link DCH-M225 Wi-Fi Audio Extender for under 17 quid. Not sure it is stereo.

I would have suggested a radio mic as well. I have a 2 channel AKG setup here that I used to use with guitar and mic. I'm probably never going to use it again and don't know whether the frequency it uses is legal since all the recent changes.

Think the ones which were 'licence free' still are OK.

Wireless headphones? Tx should be OK, though may have trouble finding a battery powered one but a pack of the right voltage and suitable lead/connector sorts that. The Rx really nneds to be a stand alone box with headphone socket rather than built into a set of headphones. Bit of ashot in the dark buying a set built in with the idea of extracting the electronics and fitting into another box.

I'd not like trusting a wireless approach, so I'd want a backup recording a t the desk, which means hardware that can record unattended.

OK that might be a suitable transmitter, but what about a receiver.

Radio mikes all seem to be mono, so I'd need two transmitters. Also, it goes a bit against the grain to have to attenuate a line output down to microphone voltages.

Not important enough to need a backup. And the point is, with the recorder in front of me I can watch the signal meters, and/or monitor via headphones. Also check that I'm not running out of battery or memory.

That's a *really* good thought. My wife bought me a cheap one years ago thinking it was the sort of gadget that I'd like, but in fact it became superseded by iPods and smartphones. The transmitter turns out to be a battery one and to have RCA inputs as well as 3.5 mm.

Turns out to be operating on the 100 MHz band and to have a "Radio" option. ATM I can get radio stations but can't persuade the phones to listen to the transmitter (still worth playing with).

I suspect that VHF ones may pick up too much interference around the power amps.

Are you really getting meaningful stereo out of a stage mixer? If so, I'd ask why they'd bother. ;-)

The radio mics I used to use accepted a line input in a rather more sophisticated way than just attenuating the mic input. But I've no knowledge of the budget end of the market.

Something like this?

Two should work together, one sending and the other receiving.

I have one for trying to link the caravan TV to the bluetooth speakers. Not got that running yet (first one had a firmware issue so supplier replaced it and left me the old one) but I did test the partly functional one and that worked fine as a receiver plumbed into a DAC port on the amplifier. Transmitting from an Android tablet.

Battery powered, charged via micro USB, so a Power Bank could give extended life.

I'd have said it was pretty normal. They use an amplifier/speaker stack each side of the stage with vocals centred and guitar and bass biassed towards the physical location. When they play with a drummer he normally sits in the middle, unamplified.

Thanks! I knew there ought to be something out there. Actually ordered a pair of these instead:

£3 cheaper by sacrificing the optical.

OK. To me, it would be more important to get a half decent balance anywhere in the hall than to play with stereo.
