    Audssey set up and Speaker settings using Onyko Receiver TX NR809

    Just purchased a Onyko TX NR809 receiver. This is my first receiver using Audyssey. What do you put the mike on for audyssey set up? I do not have a tripod. Should it be placed on the seat in the listening position or on the floor? The manual just states to position the the mike in the listening position. Also, for speaker settings, the receiver does not let you set it at full band without a sub. Should i set it at the frenquency response of my speakers? My speakers are, Dynaudio Focus 140's on sound anchor 3 post stands, center channel is Dynaudio Focus cc200 on top of the tv, Sony KD34xbr960, rears are Mirage OMRS2, no sub yet, working on that. One last question regarding impedance settings for center and rears. My center is 4 ohm and rears are 8ohm. The receiver has two settings, 4 or 6 ohms, what should the receiver be set at? I am using my Plinus 9200integrated for the fronts, no problem their.

    Thanks

    This sounds like a good Ray or Andrew question.

    If you do not have a tripod I would put the microphone on the back cushion of your primary listening/viewing position to start. This will ensure the mic is relatively close to ear height for your measurements. When your receiver asks you to move the mic to the second, third and further positions be sure to make moves of less than 1 foot each time. So, position two should be no less than one foot away from your primary position. Just make sure you mirror your movements right and left. So if you're one foot to the right for position 2 then position 3 needs to be one foot to the left of the primary or first position.

    Since you do not have a subwoofer set the speakers to as close to full-range as possible -this may be 40Hz on your receiver, though there should be a full-range setting. Just know that once you get a sub you'll have to repeat the Audyssey process. I would, at that point, set the speakers' crossover to 80Hz (THX) since you're using bookshelf speakers.

    I would look the impedance question up in your receiver's manual since each receiver is different. Some suggest putting 8-Ohm speakers with the receiver set to 6 Ohms where as others recommend 4. Your manual should answer this question for you best.

    Hey Brian. In regards to the receiver settings, it is generally better to match the receiver with the lowest impedance speaker in the set, which is 4 ohms in your case. Basically the amp will allow more current to pass to the speakers in a 4 ohm setting, but unless you are turning up the volume to very high levels the impedance setting is not as pertinent. At moderate levels the impedance of the speaker will fluctuate with frequency of the signal being played. Thus the actual impedance will likely be higher than 4 ohms most of the time. You could play with that setting and listen to the differences, you won't hurt anything unless the volume is very high.

    Nice insight Matt, thanks.

    Matt/Andrew thanks, that helps. I do not listen at very high volumes but loud enough to enjoy.
