Onkyo 805 setup

Gizmo99

I just bought the Onkyo 805 and I have some questions, maybe other 805 owners can chime in.

1) With my Yamaha 1800, I was able to set my FXI3 / FXIA4 to "small", therefore no base goes to those speakers (I think). Whats the equivalent setting on the Onkyo 805?

2) With my Yamaha 1800, it was able to detect the bass crossover which allowed me to turn up the cross over on my sub to max. On the onkyo 805, it doesnt seem like its able to set the cross over on the LFE. What cross over should I set on my SUB?

Thanks in Advance

1. Its more advanced than large/small, you can set your xover at 40-50-60-70-80-90Hz for center, fronts, surrounds and rear surrounds.

2. In speaker setup(2.2), scroll down an you can set LPF for the LFE at 80-90-100-120.

Are those crossover settings specific to the set of speakers I have? Do you have the same setup?

thanks

The FXi3 has a spec down to 50Hz
The FXiA4 also lists 50Hz as lower limit

Both have a -3db lower limit spec of 60Hz

If this helps ... so 60Hz might be a good number, or you might want to just tack on 10Hz and call it 70Hz as a good xover point for those surround/rears

Your LSi15's -3d lower limit is 30Hz

Thanks Wizzy.

Whats the difference between "Direct Mode" and "Multi CH" on the 805?

wizzy

Got me on that one ... have you checked the manual?

It won't hurt the speakers if you set the crossover frequency lower then your speakers can handle right? For example, the RTi8's do down to 30Hz so if I select Full Band it'll possibly send signals lower then 30Hz to it.

I know you won't hear anything and I'm almost certain it won't do anything to the speakers but I want to make sure first.

Theoretically, no.

But - something to think about. The xover occurs in the pre-amp section of the receiver. If you xover at 30Hz or 40Hz, the amp never has to bother putting out those frequencies below 30/40

The lower end frequencies take more power. So, when you are making the amp push those frequencies out, you effectively make the amp work a little harder (assuming your source has those low frequencies)

So, you get less power from the amp before clipping starts to occur. At lower volumes, your amp produces more heat.

If you cut out the frequencies you won't get from the speakers anyway, you have more power for the high lowend, midrange and high end.

Also, some may say that if your speakers aren't worried about producing those lower frequencies, the midrange frequencies might just be "cleaner"

Rike255

That makes sense. All good reasons to use it. My 805 unfortunately doesn't have a 40Hz crossover setting though so I'll have to set it at 40 instead I guess.

Thanks wizzy!

wizzy

Sure.

Don't be scared to experiment with not using the xover. It's possible you may find it just sounds better letting the fronts produce the lower frequencies - depending on how well your sub does it's job, and blends in.

gizmodo99 good purchase. hope u dont mind if i hyjack ur thread. i did my own thread but only got one response. i just bought a svs sb12+ to go with my stuff. i ran audessy. it still kept all my fronts at full band which doesnt allow me to set crossovers. LFE is at 80 and i have double bass mgmt on. i was expected to be wowed but i wasnt. i felt like some ancillary sounds were louder but did not "feel" anything. any thoughts. i watched dh4 and transformers.

Did you set the low pass frequency filter to something?

If you are referring to the SVS, you always turn it off or push it as high as possible if you are using bass controls.


As for X-over frequencies, I would use this ROT: 1 octave above the -10 dB point or 80 Hz, whichever is lower. For RTi8's, this would put it at 60Hz and 80Hz for the rest. Remember, being a ROT, it's just a good starting point. I certainly wouldn't recommend putting the X-over at the -3dB point though, especially if you have a good sub....

Direct mode usually means 2channel & multi channel means just that.

But when I use Direct Mode, I am hearing sound from not just 2 front but the sourrounds too.

Are you playing a two channel source? As I understand "direct mode", it plays the dat it receives with no processing (Such as matrixing of channels, effects, sometimes your x-overs and speaker distances, all depending on the version)

I think that's Pure audio.

Direct mode: In this mode, audio from the input source is output directly with minimal processing, providing high-fidelity reproduction. All of the source’s audio channels are output as they are.

Well, there you go then!

cfrizz

You know I sometimes wish there was some standardization with this gear. Everyone gives out the same names for things but means totally different applications!

Gives me a colossal headache.:(

Gizmo99

Thanks, should have looked at that manual
