I have a Denon 884 receiver and I have a pair of in cealing speakers with a impeadience matching volume control. When I have one source playing I hear the other for zone 2. For example when I am watching a DVD with surround sound on zone 1 I can also hear (not at the same volume) the tuner which is playing on zone 2. I think that it donsn't have enought power but the place I bought it from said that I could even hook up 6 speakers thought out the house. I cannot even turn the volume on the receiver up for zone 2 all the way, otherwise the when I go in the room where the volume controll unit is and turn it up the receiver turns off. Do I need to get a separte amp? Why do I hear zone 1 and 2 bleading together and interfearing with eachother?
Thanks

I don't believe an HT receiver is designed to work with an external volume control like that. I could be wrong, but either way it is overloading the receiver and forcing it to shut itself down for its own protection.

the volume controll should not be turned all the way up for zone 2. i have seen many people try this, leave the zone 2 volume all the way up and use the impedence matching volume controll to turn it down in the zone 2 room, with yamaha and denon receivers and it always has the same result, amplifier shuts down.

you should turn the zone 2 volume to a level where you will actually listen at and then use the impedence matching volume controll in the zone 2 room to go down from there. the denon definately has enough power to run any in ceiling speakers and too much power for most which is more likely the problem.

as for your other problem, i have never come across this, it may need to be serviced.

I turned the receiver to where it dosn't turn off but the when the volume controll is all the way up it still dosn't sound loud. I want my in ceiling speakers to be loud. As far as the bleading goes I cannot figure it out. Why does the in ceiling speakers not get loud enought. It probably would but I cannot turn the receiver zone2 up all the way because the receiver goes off.

i would assume with the IM volume control you are driving the amp much harder than you tink. Connect the speaers without the VC. I believe the Yahamas will attenuate the volume. Should make your speakers sound MUCH better. I would however NEVER connect in this fashion. ALWAYS use a separate amp.

before buying a second amp consider getting a second reciever for the same money. Seperate tuner, easy to use and never a problem

First, getting this type of speaker loud may not really be possible. Volume is subjective, so I don't really know what you mean by loud, but this really isn't the design for loud playing.

Next, you probably either have some wires crossed somewhere or the receiver has internal damage. Or both.

Is it just radio that is bleeding through, or any source?

Pulled up the PDF manual on this unit, and it has a line that states:

IF another pre-main (integrated) amplifier is connected, the ZONE2 jacks can be used to play a different program source in ZONE2 at the same time.

Meaning? Yes, you really should get another amp/pre-amp for the second zone. Using the on board surround sound back amp just isn't a good way to get where you want.

And, for what it's worth, you don't really need a IM volume control in this case. It certainly won't hurt, but it's not needed.

No clue about the sound leakage.

Speakers won't play loud enough. How much power does that amp have? Let's say you DO hook up eight speakers throughout the house. When you do, you have to set the impedance matching volume controls to x8, because x6 is not available. Every time you do a x2, you lower the possible sound level by 3 dB. x8 = 2x2x2, so it lowers the sound level by 9 dB. If your amp has 50 watts, then each room will get 50 watts less 9 dB, which is 6.25 watts per room. This is why they might not play loud enough.

I had a problem with amp shutdown because of the second zone on a Denon 3803, and I talked to Denon about it. In the conversation, it came out that they really did not intend for the second zone amp to run more than one pair of speakers. It is not designed for that. In particular, the amps cannot run with a low impedance at very low frequencies.

Impedance matching volume controls have almost zero impedance at zero Hertz, in other words at DC. Measure one with a meter. Around 100 Hz, they are up to snuff. In between, the impedance rises from zero to around 8 ohms (4 ohms for some of them).

If the amp you are using cannot handle loads below 4 ohms at very low frequencies, this type of control can cause the receiver to shut down. If there is no signal at those frequencies, it might not matter. (Some amps check for impedance when they start up, and will not connect to an impedance that is too low. Some just shut down when too much current flows.)

The Denons seem like they could be used for multiroom setups with impedance matching volume controls, but that flaw can come into play. I have used them for several such situations with no problem, but blown one receiver in another system.

If you MUST do this, use a variation of a Zobel to maintain impedance at low frequencies. That kept my problem amp from blowing out, and the tech at Denon thought it would be a good idea, although it had not occurred to her before.
A good answer is easier with a clear question giving the make and model of everything.

What preamp do you think that I should get just to get enought power? I am not trying to buy a really expensive apm just one to get it enought power?

Get a stereo receiver for under $200. Whatever brand you like. Onkyo still makes a halfway decent stereo receiver for fairly cheap.

I don't really want to have to get a sterio amp because I have my tivo connected to my denon receiver and I play music throught the tivo and make the zone 2 play tivo for the music. Isn't there a way to give the denon power or the speakers power thorough another type of amp?

A Receiver is an amp.... It just has a Tuner in it also.....

WHile I strongly dissagree with the comments about a receiver being better or just as good as a dedicated power amp... THey work just fine. A Speakercraft BB50 wil loutperform any receiver under $600 for sound quality and even volume levels in most cases.

Ty, do you have an older stereo like a McKintosh lying around collecting dust? Find something you can abuse a little bit, usea line in, and CRANK IT UP baby.

I do have a couple of amps laying around but how would you huck up the old amp to the denon? Are you saying that the old amp would give the denon more power, or are you saying that I should hook up the in ceiling speakers directly to the old amp?
Thanks guys
