Nakamichi receiver av-2

Hi, do you mean you need the AV tuner/processor unit? If so I have a Nakamichi Soundspace 12 one for sale, in perfect working order. Let me know.

I can't find a manual either. Can I assume you really mean the sound is muted for EVERY source, not just tuner and CD?

I'd guess it's either MUTED or a Tape Monitor is active. Turn the volume down, select FM as the source, tune a station and use it as your test source. Look around for indicators that give a clue.

NEVER troubleshoot anything with the volume control turned way up. You'll blow up or damage the speakers and your hearing right after you discover and correct the misplaced control.

I could find only little information about this receiver, but it seems that is supports only 4.0 Dolby Pro Logic.

Hi,\

Its an issue with the tone switch activate and reactivate it to get back to normal volume on both speakers, and would suggest you to clean the switch with WD40 and it should resolve the issue

This may sound silly, but make sure that the tape monitor switch is not turned on. If it is not, let me know and we'll look elsewhere.

Nice Receiver!
>In your surround sound settings make sure the levels are set correctly and the distance from your listing point to the furtherest
speakers are set to accommodate the levels etc.
>How many speakers 5.1, 6.1, or 7.1 (1meaning subwoofer)
>Pro-Logic supports 5.1 but not sure about 6 or 7
>Pro-Logic II does support all
>Make sure you are hear the sound from all sometimes the sound is really faint if you are in surround mode

Thank You and good luck

HAI,IT'S A SMALL PROBLEM ANY DRY SOLD INLEFT AUDIO SECTION

I don't know the design of this reciever, and do not have any schematics or engineering information to know the design.

This is a general comment:
In many of these recievers at this level they don't have very good muting designed in to their system. When switching sources, the audio is not being muted.

This is a theory of why the noise is not on the main speakers, but present on the sub woofer. Because the switching noise is of very low frequency, this is why the sub woofer is making noise. The main speakers lack the low frequency sensitivity that the sub woofer has. This is one way of looking at it. It is also possible that there is muting for the main speakers, and none for the sub woofer.

If the reciever does have muting in to its design that is supposed to mute when switching modes, then there is an obvious defect. When a source is switched, or a mode is changed, the output would mute for the duration of the switching interval. This is usually for a period of about 100 ms.

Your best bet is to contact the service rep for nakamichi and ask the question there.

I have serviced many recievers made by other manufactures. The higher end models all had muting in their design. This way, the output was muted when the source was changed, and when the reciever was turned off or on.

could be the speaker, try connecting another speaker and cable and see if it improves. If the problem is still there and you've checked all the settings insuring that its not turned down, then could be an internal problem with the receiver.
Hope this helps a little at least.
