Feature:
The features are pretty much meat and potatos. You can run 1 0r 2 speakers mono or stereo, so you have flexibility. The secret is to run your output mono and split the signal so left goes into the unit and right goes to your direct connect speakers. Adjust your direct connect speakers to a lower volume to compensate for the level cut on the braodcast of the unit.

Quality:
A little more durability for the transmitter would be good,. but as long as you take care of it,. you'll be fine. I carry mine in a padded case. The receivers are great.

Value:
The price could be a little lower in my opinion, but for the times I have used these and needed them, they are soooo worth the money. I have been hired as a DJ for a few events because of my ability to run wireless remote speakers in addition to the mains.

Desirability:
Looking at the unit you may not think too much, but once you have used it when it needed, you'll appreciate the unit that much more. Dont discount the non-digital version either. It works just as well.

Sound:
The sound is fine as long as you are not too far (within 100 feet is great) and dont have interferrence issues. I have run into situations where there was noise from a battery back-up emergency lighting system, but if you use common sencse in the set up you can avoid potential problems. The levels drop a bit compared to a direct connect, but you can easily compensate. Again, use common sense in the set up and test before hand.

Ease of Use:
Once again, its easy to use,. just test out the relationship of sound levels between hard connect and the broadcast level. You'll need to have a strong signal going into the Phonic transmitter. MAKE SURE YOU USE THE CORRECT POWER ADAPTER!! The transmitter and receivers use different power.

Support:
Never needed support from either the manufacturer or zzounds for this product.

Overall:
I have been very happy with the product. I would replace it if anything happened. I have used other products, and this does the job just as well, with an easier set up. I like the service it allows me to provide for some weddings and DJ gigs. What I like least is the VU level difference. You need a much hotter signal going into the transmitter than what you would normally run to a powered speaker. YOU HAVE TO GO DIRECTLY FROM YOUR MIXER/PLAYER to get an adequate signal level. If you go from the mixer to the speaker and chain back to the unti the level will not be enough to get a signal. Thats the biggest downfall of the unit, but again, testing ahead of time and using common sense in your setup will take care of that for you.
