The 4-ohm setting limits the amplifier's output. That's it.
I will watch the video later since I am at work I have someone next to me that I'll bother lol!

For now by great risk I mean damaging the speakers or avr.

For example if my speakers are 8ohms and I leave the impedance at 8ohms will I limit the output that way or will I limit the output by setting the impedance to 4ohms using 8ohm speakers?

Do as grubavs just said above; the Speaker Impedance setting @ 6 Ohms ... That's the best, for your speakers impedance, and even if they would be all 4 Ohm rated speakers, like mine. ...I always kept that setting @ 6ohms. ...Your 805 loves that selection best, and your speakers too, and finally your ears and your room's overall dynamics.

If you try the 4 Ohms selection, you'll have less current, less power (RMS watts) in your speakers...less juice...less swings between macro and micro dynamics, and you want all the "swings" you can get.

But to answer specifically:

You will limit the 805's (any amp's) output by selecting any lower speaker impedance setting... that's what a lower setting does.

Ok thank you I will leave it at 6 ohms. Now for learning purposes if you try 4 ohms that puts a limit regardless of what ohm your speakers have? I always thought if you have 4 ohm speakers you do 4 ohm setting on avr and so on.

How come some speakers are rated at 4 ohms if you are to leave the impedance at 8ohms?

Page 45; the settings are 6 Ohms and 4 Ohms. There are NO 8 Ohms setting.

- 6 Ohms setting: For all speakers, with all the receiver's current. ....Best for all, and all for best.
- 4 Ohms setting: It shouldn't be there, it's more for ultra hi-end electrostatic loudspeakers that dip into 1 Ohm or less. ...Then it might save the receiver.

I only mentioned to make a point; 99.9999% of all people who own a receiver like the Onkyo 805 will set the Speaker Impedance setting to 6 Ohms.
And if you have speakers that go lower than 3 Ohm across most of the audio range (20Hz-20kHz), then you simply don't use a receiver with those, you buy CITADEL mono power amps, with 2,000 watts minimum into 1 Ohm speaker impedance. ...Roughly $500,000 each. ...And weighting 650 pounds each.

Anyway, the Onkyo 805 you can get for twenty bucks now, and it's good with ALL NORMAL speakers (4 to 8 Ohms rating). ...And with the switch selected @ 6 Ohms.

<<<>>> Experiment, try @ both settings, but! ...if you do you'll have to rerun Audyssey MultEQ XT. ...Each time you switch (page 45 in your manual). ...I think.
...If you listen with Audyssey engaged, of course.
You won't damage anything.

I gave up teaching because it is so unrewarding, so I repeat... read this link... it'll take you less time than it takes me to write these posts and you will be correctly educated. Watch the video section at your leasure:

I see now. I will just leave it at 6hms like before. Thanks!

Are the new onkyos more powerful than the 805?

The 3030, maybe. ...But then maybe not.
The 805 is a true solid THX Ultra2 certified legend when it comes to real power into 2 channels, 5 channels, and 7 channels all running simultaneously.
...A real powerhouse of a receiver, and @ the street prices they were a tremendous value.

...The power, the glory, and then the abso!ute decadence...heat and HDMI board's failures. ...2007, 2008, 2009, 2010, 2011, 2012, 2013 models...all.
Many are still running strong (with fans on top) and many went caput (still with fans on top).

That is the exact reason I can't give up my 805. The power is just unreal.

The 805 (51 lbs) has 7 internal amps and weights 2.5 pounds more than the 3030 (48.5 lbs) which has 11 internal amps and has the lower THX Select2 Plus certification.
The 805 is more powerful, I am certain, from real measurements. ...And the 805 is incredible into 4 Ohm loads in stereo....extremely powerful for a receiver @ that low price point.
...It's called "current". ...And four Toshiba transistors (2 pairs) per each channel. ...I remember some folks who paid $450 (USD) for it back then, street on sale, brand new.

In 50 years from now, a mint 805 might be worth $5,000 ? ...Maybe not, perhaps $2,200 (twice its original MSRP). ...The legend, the classic vintage in mint condition.

I was lucky enough to get the 805 from Ebay about two years ago for around $225 with the remote and mic. The original owner used it for his dedicated theater and was in mint condition no scratches or nothing. No hdmi issues either but yes I have two fans of top. You can fry eggs without them.

I know some audiophiles with audio gear worth in the six digits, but they only paid with four digits...hi-end audio gear from yesterday...second-hand audio gear. ...It's not the money for the gear you paid and possess, it's the music you listen to. ...And the films you watch.

The 805 is still keeping this thread/music/cinema dream alive.

Mine is still frying eggs! Whit all its power

My '91 MR-2 Turbo was one of those classic vintage things... a real eye-opener for an unsuspecting passenger when at 65 MPH I down-shifted to 3rd and jammed the pedal! 105 MPH in about 4 seconds! Screamin'

it seemed like 4- seconds, anyway

SR805 with Panasonic TC-58AX800U 4K UHD TV - Audio problem

I've got a Panasonic TC-58AX800U TV I'm trying to use with my SR805. When using the TV's built-in Apps (Netflix for instance) I can't get any audio out of the 805. Otherwise, all other connections to the receiver have no problem with audio going through the receiver (Cable box, Blu Ray, Apple TV).

Panasonic support is telling me it might be that the receiver does not support the digital signal from the TV. I've tried multiple input connection configurations. I'm using HDMI 1.3 cables.

Does anyone know if this receiver should be able to accept digital audio from this TV?

Do you have audio wires going from the TV's audio outputs to the 805?
