Question about Yamaha NS-A60X Main / Stereo Speaker

1 Answer

I just purchased a yamaha RX-V767 receiver. I have a polk surround sound speaker system 5.1 that have an impededance of 8 ohms. The receiver has an impedece adjustment knob on it. would it be safe to adjust the speaker impedence on the receiver to 6 ohms without causing damage to the 8 ohm polk surround system. I am going to purchase some floor speakers that have an impedence of 6 ohm. would this be safe for all speakers. and would it maintain the high level of sound

No, you don't want to do that. The Ohm output on the amplifier must match the speakers. Run 8 Ohm speakers on 8 Ohm and run all your speakers on the same impedance (Ohms). Your gonna burn your amplifier up if you run different impedances.

    Actually, since you have an adjustable knob for impedance just set the knob at 8 Ohms (If the is the highest rated speaker) and you will be fine. Do this and you will be fine.

Hi. You can always use a Receiver with an output impedance that is lower than the speakers input impedance.Problems arise when you try to use a Receiver with a higher output impedance than the Speakers input impedance.

Just a question, not a problem yet. I do not have speakers for my RX-V665 and do not know what to get. My mid and rear speakers will be mounted in the ceiling (a suspended ceiling) I am worried about...


Why does impedance concern you? This receiver can be configured for loads as low as 6 ohms. The front speakers can be 4 ohms if you use a single pair.

It's all explained on page 106.

This receiver should be able to drive most quality speaker systems. Anything from ub/satellite sets to 6-matched speakers plus a sub will work. It seems you have a choice already made for surrounds. Whatever yoy choose, you have to balance performance, aesthetics and price. The Yamaha is probably not a limitation. Get what you can afford and place to your satisfaction.

Pushing 4 ohm speaker systems


Officially this receiver supports only 6 and 8 ohm speakers. But for surround speakers it should not do any harm, because they are not played at full volume. But be sure to set yamaha for 6 ohm speakers.
Using only 4 ohm speakers makes the amplifier work more hard and produce more heat, that's why you can't use it at high volume.

Can I mix 6 and 8 ohm speakers?


I would not suggest mixing. Use either 6 or 8 only but i highly suggest not mixing unless it gives the option to set a certain input for a certain Ohm. If you mix your either going to mess up a speaker or the receiver itself.

Sounds like a poor grounding issue between the units OR maybe they're not as compatible as the Mfg's say.

Could be a bad HDMI cable also. Most are made in the land of Nanking

Setting up a Yamaha RX-V690 home theater system


you almost have the exact same situation i am in. i have the same receiver, and going to purchase a panasonic 50" (th50px75u). i think what i will be doing is running a hdmi from my hd cable box to my tv, and installing an audio cable (red/white) from my tv to the receiver. i believe there is an audio input below the hdmi insert. i have polk audio, but theyare about 10 years old, they sound great, but just too large....and may be purchasing a harman kardon system. which models do you have from polk? i have the rt16's, cs350ls center, and fx/500 rears. let me know what you have come up with as well...as it has been a while since you posted this.

cheers,
sean
