New TX-NR626 installed on Nov. 4, 2013
Speaker setup is 5.1 without a Woofer, in speaker setup manual mode, selected Front Normal, No Woofer, and surround, No back surround.
When setting up the calibrations for the speakers, all emit the signal from the correct speaker, I.E. I can see the visual on the screen, and hear the
calibration level from the highlighted speaker. I set the speakers to a relative level based on the distance to the speaker in use. Distances were also set.
Low freq cutoff was specified for each at about 50-80 hz.
So all of the speakers are wired up correctly, and respond properly in the manual setup. Speakers are the Bose 301 series II Front and surround, Center is a home brew 8" woofer and tweeter with cross over, no issues with speakers. again no woofer.
Tried to run the Audyssey setup.
Plugged in the Microphone, heard an internal click of the receiver, screen display comes up with the instructions. Set the mic on a tripod at the listening distance and height.
Tried running the Setup in the simple mode first
Receiver starts the routine by chirping the Front left speaker, does this three times, each time the level of the volume output of the speaker was increased
after the third attempt, display comes up with Error..( if I recall correct, data fields were empty) Tried the setup several times.
Tried running the advance mode, eg the multi position calibration... same results..error after the left speaker goes thru the three levels then show no data and
routine ask try again/cancel. same results.
Rebooted/reset receiver... Same results.
Checked to see if Firmware update was needed. updated the firmware to 1040-7110-0000-0201 successful.
Tried Audyssey again... same issue....no go...reset/rebooted...same issue no go... unplugged receiver overnight...retried audyssey.. no go.
Microphone label on box says ACM1HB...3.5mm silver plug with knurled 1/4" rubber band on plug
Have I perhaps missed something in the setup menu's or perhaps a bad microphone/cable?
Not sure how the rx is designed to detect the microphone, via the plug insert only or perhaps a check of continuity via the microphone ckt.? My guess is a switch action on the female jack when the 3.5mm plug is inserted.
Resistance of the microphone checks as 1.1k with high quality digital ohm meter. So microphone is at least not open ckt. Not sure what the value should read, nor if the mic works. I do not have anything that would substitute for the supplied unit.
Any suggestions appreciated.
It appears at this point in time the other functions of the AVR appear to work properly.
Thanks in advance for any suggestions
