then what could be my problem here ... my unit keep short me ... do I need to ground the unit .. or something else is wrong ......

yo djdyks,

I dont think you will be able to reuse the sub directly to the 861. The preout SW will output the decoded raw sound signal from the sound source. By any means I dont think the preout SW signal will have much driving current to drive the sw.

If you connect it to the surround / surround back output, the subwoofer will be playing 1 of the surround signal/rear surround signal. However, SW should be designed to reproduce lower freq signals, but the surround channel will contain either the full signal (all freq - if you set your speaker to large), or signals that is higher than your crossover freq (if you set your speaker to small).

If you've done YPAO on your 861, it should detect the connections / speaker configuration for you. Without the subwoofer detected on your setup, i believe the 861 will set the LFE/bass out (SET MENU>>MANUAL SETUP>>BASIC MENU>>SPEAKER SET>>LFE/BASE OUT) to FRONT, where the FRONT will try to output the LFE signal, and Low-frequency signal (signals where your speakers is set to small - redirect the signals below crossover to the FRONT).

That's well said Kiam. But only set your speakers to large if it can handle frequencly as low as 30Hz. If not, it could hurt the speakers.

If you connect to other than the sub pre-out, what your sub is receiving is only the frequencies intended for the original speakers, and usually these channels won't go as low. And most importantly, you'll not hear anythng from the dedicated LFE track in movies (the .1 in the 5.1 channels).

As most receivers only have subwoofer pre-outs, the subwoofer must be active, meaning it has a built-in amp. It can never drive a passive subwoofer by it's own.

Djdyks, does you mini hi-fi got line in? If yes, you can use it as an amp for your sub. Connect the pre-out to the line in, and the subwoofer to the hi-fi as usual. Turn it on and select the line-in input. Run the auto-calibration again at the 861 again.

This is temporary solution, my advise is to get an active subwoofer quick.

I experienced the same thing, not only "short" by my AVR but also my DVD player since I stack my AVR on top of my DVD player due to limited space. Have you try to plug your unit to other power plug in your house by using longer power extension? You can try that first cause previously I experienced the same thing on my PC but when plug to other power plug then it was OK. Think might be due to the connection inside the power plug on the wall which didn't ground properly.

makes lots of sense, will try it when i reach home tonight .. if not i'll feel over energetic everytime .. kena short ..

about setting speakers to large .. and small .. hmmm i better check my configurations .. I just hantam only ..

Anyone can guide step by step important things to check with my yammy avr?
What i did was only set impedance to 6ohms and then run YPAO.
*I'm a lazy kind of person ..

Ever wonder why some electrical appliances comes with 3-pin and plug and some got 2-pin plug ?
The 3rd pin is for ground connection ... u can either connect a 'ground' to other elec. appliance with 3pin plug ...
Actually it is using your body to discharge to ground ...
I remember my Yamaha 861 got a small part at the rear panel purposely for ground connection ... check it out

Actually you can refer to your user guide, think there do guide u how to set it to default. However, I set my front to large and both center and rear to small as what it is then run the YPAO. Sound was OK but I haven't set it again after bought my Sub, will set it again when free so that the setting consider the Sub as well. I used all default setting since I'm not too expert in all those setting but sound was OK for me

Added on August 28, 2008, 12:08 pmOh OK djdyks, if u didn't mention I also didn't notice about those small part at the rear panel purposely for ground connection. I'll check it out but how do you connect from the small part at the rear panel of your AVR to the ground? Izit just connect a wire from there to another 3-pin electrical appliance? Or can I just connect the wire to the TV rack which was make from metal? Thanks ya

wonderful .. but the dvdp leh? only 2pin plug wo.

Even you have big speakers, always advisable to set them to small if you have a sub. Let the sub handle all the low signal below the cutover freq. The sub meant to do just that. In layman term, your speakers dont have to work hard for those low freq and will let them handle the above freq more efficiently.

* your speakers considered "big" if the driver is at least 6.5 inch or bigger and not bcoz the enclosure can't fit in you car

Even if the driver is 6.5" but if it can't handle frequencies as low as 30Hz, I still recommend to set is as small so you can crossover the low frequencies to the sub. When set to large, all the frequency range will be fed to the speakers. This is most important while listening to stereo music (if you use subwoofer, not pure direct).

For 5.1 source, the low frequencies (maybe <80Hz according to THX standards) have already been discretely channeled to the LFE (.1) track by in the studio's mixing room. But you can still set the AVR to crossover low frequencies from the small speakers if the speakers' low frequency roll off is high (maybe 120Hz).

If the lows of ur speakers differs too much...time to upgrade amp that can handle each channel discretely

I am. Tomorrow night I should be able do bass management for each speakers. But that can't be discussed in a Yamaha thread.

I'm so jeles...

Need help. If price is not an issue, which should I get? Yamaha 3800 or Onkyo 805?

Learn yourself to forget. Jealousy can lead to hate, hate can lead to greed. The shadow of the dark side, that is.

Yamaha Z11

Only comparing those 2 models cause I can get it about the same price. Can someone help me out here

Why so serious?

3800 and 805 are not in the same league even though they're in the same price range. 3800's match is 875.

Go for audition with same set of speakers. If I were to choose between those 2 (if I like both sounds), I would still choose 805 because of small extra features it has.

Oh,now I understand. Thought if I set my front speakers as small then it will need to work harder OK,in that case I'll set it to small and run the YPAO again. Ohya arremie, may I know how do I ground the AVR? Cause always get electrical shock by the AVR and DVD player. Is it possible if I just connect the AVR to the metal make TV rack?

Your rack made of metal, alrite ... but is it touching the ground DIRECTLY and without any bushing or rubbers? If it is, then ok ...
Any metal body part of the DVD player can be routed to connect to other electrical appliances which comes with 3-pin plug ...
Or guys can try wearing slippers or anything to avoid contact with the ground and try 'touching' your elec. app. and test whether it works ? It'll prove whether my idea works
NO WARRANTY for my suggestion ... take your own risk

Hahahaha, OK djdyks I'll try on your suggestion and see how la...Ya, my TV rack make of metal but think there is rubbers at the bottom of it. However, I can try on it see whether it help or not. Thanks ya djdyks.
