Except living room , none of the speakers are working

hallo Friends, need your help.

I recently moved in to my new home where the previous owner had recievers and in-wall speakers in every room including pateo.
But the number of wires from the outlet was total 8
1 set means combination of red and blue wires.
1) 1 set of wire for main stereo.
2) 2 set of wires for front speakers
3) 2 set of wires for 3 rear speakers ( only 2 working)
4) all the other wires are combined into 2 set of wires ( but only one pair of speakers from one room)

Other room speakers are not working.Even Base in-wall speaker not working.

I have onkyo 9.2 . What i need to get soound from them .

I am sure the previous owner had them working. But they dont respond to my text . They are bit shy

...sounds like you need to have a professional in there.
There are ways that you can troubleshoot all of the wires yourself.
Must be done...
One wire at a time.
One speaker at a time.

as @Espo77 said, a pro help would be best. However if they do not reply, here is how you do it yourself, one wire at a time.

1. I do not understand the main stereo wires and then front speaker and rear speakers. Are you saying that there are 2 areas for listening, one area for 2 channel music and then one area for home theater?

2. For the 2 sets of wires and one pair of speakers, do you have a second set of speakers outside that you missed? That would be a zone 2 or 3 setup. If not, then maybe there is a volume knob somewhere in the home that you missed?

Ok, first get a friend, some duct tape, a permanent marker and a 9 volt battery. Have someone sit in front of speaker #1 and put the 9v battery on each of the wires until that speaker vibrates. Tape that speaker wire and mark it appropriately. Do that for all of the rest of the speaker wires until you have all of them labeled.

satyajit,

To rephrase:

The previous owner took his electronics,
but left the in-wall speakers.

In the living room, 5 speakers work:
front (right & left), rear (right & left),
and the "1 set of wire for main stereo" -- the center channel. Two other speakers do not work: the "base" (subwoofer?) and the third "rear" speaker.

In the other rooms, none of the speakers work.

So: The 5-channel surround theater speakers all work. The subwoofer doesn't. Zone 2 and Zone 3 (as eriksells recognized them) don't work. Does that correctly describe your issue ?

1)
Can you take the cover off a Zone 2/3 speaker to see what's inside ?

2)
Crutchfield lists 7 in-wall subwoofers. All are "passive" (needing a sub amp that is NOT in the wall). All have 8 Ohm or 4 Ohm impedance.

With that in mind, I would _guess_ your in-wall subwoofer is also an 8 Ohm passive speaker.
You'll need a sub amp between your Onkyo AVR's pre-out and the subwoofer.

How could you verify this? I imagine you could temporarily connect the Onkyo's right channel to the subwoofer, but I've never done that.

3)
In the living room, is the non-working third rear speaker merely another one of the Zone 2/3 speakers that don't work?

satyajit,

1)
"one pair of speakers from one room"
Maybe the two combined sets of wires are stereo Zone 2 Left & Right, not independent Zone 2 and Zone 3.

2)
How are the wires physically combined?
Are they soldered? Bolted to a copper bar?
Screwed into a big wire nut?

Would it be easy to separate one red/blue pair from the rest, to identify its speaker(s) ?

I am so lucky to get so much detailed response from learned members of the forum.

I realized one thing.


My living room main speaker, 2 front and 2 rear speakers are working and sound Loud.

All other room speakers and the base , looks like combined into 2 set of wires from the wall. They sound low. They are actually working , but after making the volume controller in each room highest, it sounded faint.

Do i need some kind of amplifier or something.

satyajit,

Yes. You could use the AVR's stereo Zone 2 pre-outs in two different ways:

STEREO AMPLIFIER
This is certainly what the previous owner did.
Connecting four 8-Ohm speakers in parallel would present a 2-Ohm load to the amplifier. (Could this damage the amplifier?)

STEREO AMPLIFIER + SPEAKER SWITCH
You could separate all the wires from the two combined bundles, and connect them to a speaker selector switch.

"Geoff the grey geek" describes three different kinds of speaker selector switches. They are all intended "to keep the total impedance safe for your amplifier".

Thanks a lot for the help. I feel like i am almost there with your guidance to finally listen to all the speakers.

But frankly i did not understand what i should buy.

I have zone 2 and zone 3 . But in wonder the wires are all combined together and all i get is 2 set of wires from the wall.

Can you please explain a bit and also suggest me links from amazon/any other sites.

satyajit,

1)
I believe the previous owner connected the other rooms in the simplest possible way: as stereo Zone 2. (I still don't understand "base".)



How powerful does the stereo amp have to be ?

Pretend for a moment that you can use the AVR for comparison. You can hear a low, faint sound. If you want the sound to be 4 times louder, you need 100 times more watts. That's crazy -- so the AVR can't help you. (I doubt it can drive a 2 Ohm load.)

Many car stereo amplifiers claim to be "stable" under a 2 Ohm load.

This amplifier offers 675 Watts per channel at 2 Ohms. (There must be other stable amplifiers. This is simply the first one I found.)

https://www.accessories4less.com/mak...pen-box/1.html

2)
One brand of volume control has "impedance magnification" to protect the amplifier. On the volume control (under the cover plate) there's a switch to adjust that feature. Is there anything interesting under your cover plates ?

Take a 9 volt battery. Momentarily rub the two speaker wires to two ends of the battery. The speaker that the wires are connected to will make some noise. That way you can figure out which wire set is connected to which speaker.

Hope it helps.

satyajit,

Inexpensive switches would allow you to use almost any normal stereo amplifier.
You wouldn't need an exotic 2-Ohm stable amp.


There's a "protection on/off button", so
this is a series-resistor type switch.

https://www.amazon.com/Improved-Sele...-1-spons&psc=1



This claims "selectable impedance magnification", so it's an Impedance Matching Transformer type switch.

https://www.amazon.com/Niles-SSVC-4-...iles+ss&sr=8-1


I didn't look for a series-parallel type switch.

satyajit,

Maybe you already have something better than a speaker selector switch.


This PDF claims "M&STM impedance-matching volume controls eliminate the need for speaker selector boxes or other impedance matching equipment." It lists a 6-step "Volume Control Operation" set-up procedure.

https://www.nortekcontrol.com/pdf/manuals/IM1.pdf

Perhaps your volume controls are like these.


Please consider this plan for the "other room" speakers:

With everything off, connect the AVR's
Zone 2 Left speaker output to one of the
bundles of wires, leaving the other bundle
disconnected.

Follow the "Volume Control Operation"
set-up procedure. (This seems to require
2 people.)

What might the person in the "other room" hear?

Nothing at all. Maybe I'm just wrong
about stereo. Maybe this "other room"
is part of Zone 3, and is not connected.

Soft sounds from both speakers.
Certainly I'm wrong about stereo.
This "other room" is part of a
monophonic Zone 2.

Soft sounds from just one speaker.
This "other room" is indeed part of a
stereo Zone 2.

A disappointed remark from the living
room. The AVR turned itself off (to
protect itself from the load). Maybe
you don't have "impedance matching"
volume controls. Maybe some of them
are mis-adjusted, and show the wrong
impedance to the amplifier.

What will you get out of this work ?

You can label the two bundles of wires
as Left & Right (or Zone 2 & Zone 3 if
I'm wrong about stereo). That's a big
chunk of mapping and troubleshooting
your cables.

If the sounds are loud enough, you might
be able to estimate how much power
your stereo amp will need.
Otherwise, your next troubleshooting step
would be to look at a volume control. (I
hope it has two transformers.)

You'll still need a stereo amplifier.

satyajit,

We've been doing a bunch of guessing.
A little bit of fact could help a lot.

Please examine one of your in-wall volume controls. I expect it will have 2 transformers and connections for 8 wires.



It should have 2 jumpers (or a switch) to configure the volume control.





How were the settings labeled ?
Which setting did the jumpers choose?

Is the maximum wattage written on the switch? (A manufacturer or part number would be nice ....)

You could use a tone generator to test the wires. If those are all good then pull every speaker and test them individually.
