Marants SR7002 Zone 2 - how many speakers?

[Pelican170]

Hello,

I am curious how many pairs of in ceiling speakers my receiver will potentially be able to run by using its zone 2 to a speaker selector with volume control? I am moving into a house that has 4 pairs or speakers in other rooms (bedroom, bathroom, kitchen and outside patio).

I feel like it should be fine since it seems ceiling speakers are lower in wattage than home theater speakers but still curious on input.

Thanks.

do you have the manual for your receiver? it would depend on the ohm rating of the speakers as to the probable load the receivers amp will see. this is moot of course if your zone 2 is not powered but has pre-outs for zone 2.

of course, i'd say check your manual so determine what the receiver can safely do as well as determine the rating of the speakers that exist. your talking about 8 speakers total, volume control or not, it might be too much for the "pair" of speaker outputs from the receivers amp if all speakers happen to be running.

best of luck to you, keep us posted.

The Short answer to your question is one pair.

The longer answer would be dependant on a lot of factors.
First up is you mention a speaker selector are you talking about a switch that allows you to choose one other room at a time (example you can either listen in the bedroom OR outside.)? If so then you should be fine. However if the selector is actually a splitter that will split the signal (example you can listen BOTH in the bedroom AND Outside) then the answer becomes more complicated. It will come down as Solardad says to Resistance measured in Ohms. When you split a signal like that you would effectively be running the speakers in Serial which would Reduce the resistance for each pair of speakers in the line. if you have like 4 pairs of speakers you would be driving like .5 Ohms resistance which would likely cause your receiver to catch fire or at least servearly overheat probably damaging your receiver.
So don't do that.

You can work around that by using an amplifier for each pair of speakers and splitting the signal comming out of a pre-amp out instead of the powered 5-way binding posts on your receiver. you could then run the split signal to Multiple line in ports on the AMP and power each speaker with its own amp ch.

If it were me I would buy an inexpensive 7.1 ch receiver and run it in all ch stereo mode with your marantz powering the the forth pair seperately.

Hope that helps.

Hey thanks.

The manual does not tell you anything about the power rating but the speaker selector does impedance matching, so im not worried about the ohms...

I think your receiver is 110 Watts/Ch

Yes, you are correct. But it doesnt say how many pairs you can run vs. the ohms and all those details.

Either way, I was able to get an additional amp for those ceiling speakers and a speaker selector, so no worries.

Thanks.
