Hi. I m on my way to construct an house and I would like to install speakers in the Ceilings and outdoor speakers.

I have found an amplifier Named Dayton Audio MA1260 Multi-Zone 12 Channel Amplifier 60WPC. My intention is to connect one Beosound core to each of the 6 stereo zones that this amplifier provides. Is there anyone hare that has experience regarding the Dayton amplifier? Would it be possible to get a god RCA stereo out signal from the Core? Would it also be possible to get an trigger signal from the Core? The amplifier I could handle 3-30v trigger signals.

The Powerlink connector delivers a 5V trigger signal. 

I have quickly read the manual and my only concern is that you can trigger the amplifier and not each speaker group.

Would it be possible to bundle up and connect the trigger signals from the different zones until the single trigger input. Meaning that if one zone or more is active it will start the amplifier. Maybe put diodes on each trigger cable to avoid short circuit?

It has an auto-on/off option too.

Thanks for input MM. I believe that function will be enough.

This amplifier looks promising. Hope that it is as good as it looks to be. The weight is almost 20kg so it must at least be something in it... Only need 6 Core now... I believe I will start with just 3 or 4 since it’s possible to feed the zones also from the two bus lines then I can use the same Core for several Zones and later add more Core if needed. Smile

Just out of interest why would you not look at the BeoAmp 16 and use B&O amplification for the BS Cores? It works a treat and only takes up 1U in an AV rack. You can bridge multiple outputs to one BS Core as well.

Here’s one on a rack below the Cores.

Thanks for input. I could not see how to bridge the incoming RCA signal at the beoamp 16. Is it easy to do with a switch? Is there any installation manual out there? I cant find anyone...

Hi

There is a stereo mode and a BTL bridge mode. Your local dealer will be able to send you info. Otherwise I am based in Ealing

Greetings. I couldn't expand the picture enough to understand everything beneath the cores and amplifier. What else does that system do? It seams quite compact for the service offered.

Hello

This is a Mid Atlantic 21U 20” deep rack on castor base.

Shelf 1 & 2 BeoSound Core x 5, one of which is product integrated to a BV14 55. Below the BeoAmp 16 there is a 1U blank to give the Neo Pulse 8 4x4 matrix some air to breath. Then there’s a 4K Panasonic BD player and 4K Apple TV. Sky HD, soon to become Sky Q. Unifi Router and 24 port POE switch. Lastly a few blank plates for future expansion.

Thanks for your interest.

Of course I would have suggested that too.

I just thought the price difference was important to the op.

If not, then that is the way to go....it is designed for such cases.

What I could see so far is that the Dayton amplifier is much more flexible regarding settings than the BeoAmp 16 and I really like the two RCA Bus connection that is has. The Dayton amp also seems to give more power than the BeoAmp where each channel of the BeoAmp only has 25w (400w/16) meanwhile the Dayton gives 65-89w per channel.

Here are the specs of the BeoAmp 16 detailing power outputs per setting. I hope this is useful.

What does the BeoAmp 16 cost?

I'm afraid I'm recovering from the BeoVirus. Sad

You’re welcome, there’s obviously a price difference between the two items and it looks like what you’re interested in is quite a good option. Pop some Celestial BOC82 at the front end with the BeoSound Core for B&O multiroom and you’ll have a good system. As a B&O dealer I have to be biased towards the BeoAmp 16 Wink

Beovirus victim, it's gotten to be too much to list!

Hi Jeff

The BeoAmp 16 is £2600 for 8 stereo zones (£325 per zone) compared to a BeoAmp 2 for one zone at £695. A BeoLink Passive used to be £550 so the BeoAmp 16 is good value in those terms.

Thanks! I think the AudioSource is a bit over $600 US by comparison. Last time I had anything to do with such an installation was multiple channels to drive speakers on a military training range, where we were using multichannel Crown Class D amps with 70volt transformers. So I am interested in what various options cost for home use now. The Crowns were pricey but they stood up to abuse well.

Hi. Found an other amplifier that looks interesting. Dayton Audio DAX66 with matrix audio function.

This one has 6 zones and is possible to control each zone with RS-232 commands.

Do you think it will be possible to send custom strings from BLGW to it?

Then maybe it maybe could be an ultimate amp to use for external speakers and ceiling speakers etc?

Not sure why would you need to connect a BLGW and add more complexity when the BS Core is your source controlled seamlessly via the B&O music app? As a B&O dealer we use either BeoAmp2 or BeoAmp16 for multiroom passive indoor and outdoor speakers all of the time. We rack mount and hideaway all of the hardware, it just works Big Smile

You are correct. As more complexity as worse in the long run... It will be Cores together with an amplifier and control by the app.
