looking for a cheap audio wifi transmitter

j_andrews OP: The audio should be good enough for that. No offense, but the Behringers are highly likely inferior to the transmitter and receiver. Distance I am not sure. These are good for about 100" (line of sight/without walls). You can get ones with longer range for more $ (of course), and into the tens of thousands for ones used in stadiums and arenas! The nice thing with these units is that they have both XLR and 1/4 to hook up to the mixer. You can just get 2 cheap 1/4 to RCA adapter plugs to go from the output of the receiver to the input to the MAC, since the MAC doesn’t have XLR (balanced inputs). Amazon.com: Hosa GPR-101 RCA to 1/4 inch TS Adaptors (2 pieces), Black, Tablet : Automotive

I hope everyone has fun!

Great suggestions 

thank you 

this is for a NYE event hosted by two venues , next door to each other … building are connected and owned by same owner .

We intend to have a DJ in one and hopefully stream to the other with reasonable fidelity .

FYI the stereo in one is a Mac 4200 receiver with 4 Klipsch Heresey speakers 

the other restaurant has a more pedestrian but fine system of a crown amp and Behringer passive speakers 

I don’t know how far the mixer will be from the receiver, the quality of sound that would be acceptable, the features you’re after or what "budget" means to you. You’ll need a transmitter and a receiver similar to these. As with any audio gear, usually the better the specs and audio quality the larger the price tag. The units in the links below should suffice and are affordable enough for your purpose and application. I hope this gives you a general direction...

One of these from Audio Engine would probably work, but there are others that may be even cheaper.
