The Pioneer VSX-520-K & VSX-820-K Receiver Thread

[Blu Titan]

Pioneer just released the VSX-520-K & VSX-820-K Receivers. Even at the entry level, all 2010 pioneer receivers feature HDMI 1.4 (3D), and internal decoding of
high definition audio formats.

Hey guys, i'm a newbie when it comes to this tech stuff... anyway I just purchased a vsx- 820 along with some budget speakers which are Yamaha NS-SP1800BL 5.1 which i've heard some good things about...

question is the speakers are rated as 6 ohm and i was wondering if they are compatible with my Pioneer vsx 820? any feed back would be much appreciated thanks

I am also not very familiar with buying new receivers and using my existing speakers. How does the ohms thing work? I saw that my rear receiver is 4ohms and it said something about being between 6-16 ohms for guaranteed speaker impedance. I am confused. Will my speakers not work with this system or something? Thanks!

OK, your receiver can operate with all speakers that are rated between 6 and 16 Ohms.

Now, is there a switch somewhere in your receiver that says: 4/8 Ohm?
If yes, select 8 Ohm.
If no, you're good to go.

That's it, that simple!

* People buying that type of Pioneer receiver don't have Electrostatic type of speakers in the first place, so...
They have speakers that can be usually easily driven by this receiver.
And most speakers that are rated at 8 Ohms will most likely dip a little lower at certain frequencies (or not), perhaps 6 or even 4.5 Ohms.
But that is normal of all loudspeakers made in the world for the last 2,000 years?

Very seldom the loudspeakers that are impedance consistent across the entire audio range. Those are usually very expensive and are more the exeption than the norm.

>>> Average Impedance of ALL the speakers ever made is 6.8755775 Ohms (It can vary from less than 1 Ohm to over 60 Ohms+).
>>> And average Sensitivity of all those speakers is 86.9998785 dB (In-room).

Soooooooo, receiver's manufacturers aim for those averages when making their products (receivers), in order to match up with those true average ratings from those speakers.
