Review: Set to 230V BEFORE you power up - A quality product but BE CAREFUL !!! The unit crazily ships set to 115V and not 230V. The note that comes with warns of this but it’s written in terrible English. You could damage the unit. Seller. You’re operating in Europe - set these by default to 230V. Dont be lazy
Review: Great value for money and works as described. - Great value for money and works as described. The only way this amp could be better is if the automatic signal sensing switched the amp on at a slightly lower volume but that is a very minor thing.

## Questions & Answers

**Q: can I select more than one zone at a time also do I need separate volume controls at each zone**
A: This is actually one of two parts,  think of this as the power for each zone.  The zone and source audio controls should be run through separate multi audio controller.  For a better understanding the latest is the Nuvo line by Legrand. build several houses and restaurants running amazing audio on this multi channel amp.  Clients love it so far.   Just watch out for the eco friendly  auto shutoff.  If there is no audio signal it shuts down goes red on the amps,   It comes back on when audio signal is turned up/on and does take a  5-19 second warm up to bring sound up, then you get blue-lights and all is good.

**Q: Can I connect another amplifier to this one to power one more room? I believe the term is daisy chaining.**
A: I did not do it that way. Instead I used Sonos products with 3 of these amps to power about 40 speakers, two separate Pioneer amps, TV's, FM radio, laptop computer, and a Bose CD player. It worked out great for me. Before I bought the amps I contacted customer service at Dayton. They were really knowledgeable and helpful. I suggest doing that with any specific question. These are great amps and I highly recommend them.

**Q: Will this drive 16 speakers @ 8 ohms?  Forgive my ignorance but I am confused if 12 channels means 24 speakers (12 pairs) or just 12 speakers (6 pairs**
A: 12 channels = 12 speakers.  Two channels per zone, there are six zones.  Don't let the 40 watts fool you, it is more than enough power for ceiling/wall speakers to get loud.

**Q: can I power 5 different rooms each with its own volume controller?**
A: Yes.  However the position on the rear of the unit and their small size makes them better suited for initial trim and adjustments rather than constant altering.  I controlled 6 rooms with mine and the volume was always handled from the smartphone that was AirPlaying to that room.

### ⭐⭐⭐⭐⭐ Review
*by R***N on 24 February 2011*

Have two of these hooked up to 12 stereo zones in the house. Each zone is switchable from two inputs or a direct line in. Very flexible solution. I have 4 sonos zone players hooked up to two of these and it gives us 12 rooms of audio for a fraction of the cost. I am not an audiophile but they sound good to me! Update after 3 years: We have had these for three years now. Both units still work without any problems. FWIW, I have had these connected to a z-wave outlet for the past three years. This allows us to turn on the entire system (which is located in the attic) from the smartphone and control the music and the volume from the sonos. I have not even physically touched the units in more than two years - they just sit in the attic working fine and doing their job. Press the button, play the music, the z-wave automatically turns them off if we forget. I still have the 24 channels (12 rooms) divided into four zones, each with a Sonos "connect" (were called Z90s when I bought them). I would add more zones but the price of the connects make it a luxury I have just never been able to justify. If I were to do this today, I would probably put a set of airport express units on this (one can buy 7 express units for the price of two connects) and with iradio it offers much of the same functionality but would give you many more individually controlled zones. In any case, the Dayton units continue to work with no drama, no intervention, and no problems. Update after Five Years - okay I am upgrading to five stars: All good. No problems so far, they still work just as well as they did in 2011 when I first installed them. Admittedly, we do not run these a much as many people will, but still, five problem-free years. Props to Dayton (and Sonos, which is also problem-free after five years with regular software upgrades to keep the system and the app up to speed with the latest services). Five years of problem-free service deserves five stars.
