Could have got itself in a 'logic knot' . Try a complete reset ( i.e. switch off at mains , connect speakers first , switch on after a good 30secs. 'off' period and go through the initial settig-up procedure as given in the handbook.
Good luck.

How do you connect a Nakamichi surround sound system to my Phillips tv model 42PF7220A/37


I'm confused. The message header shows a problem with a Yamaha RX-V995 receiver.

As for connecting a Nakamichi (or any surround system) to a TV - the only connection would be the Monitor output (video connection) to an appropriate video input of your TV.

If it is a Nakamichi, it is a little older and probly predates the invention of HDMI cables. My guess is you will either use the S video output or Composite video output to the TV's input with similar connections.

This allows you to route whatever video sources you have connected to the Nakamichi to the TV.

No audio from Nakamichi av-10 receiver. Checked all connections and speaker buttons. Even headphones don't provide any audio


There is a protection circuit in that unit. It has a relay that is either dirty or has detected a fault that might or might not be there.

I have the nakamichi re 1. One of the speakers is playing much lower than the other. This is consistent with the headphones also. Any ideas? Thank you


Does this problem happen on only one input, or on all inputs?

Either way, the problem is in the preamp circuitry as it happens with the headphones & speakers. Unfortunately this would be a repair for a professional.

Got a Nakamichi AV-2 receiver at a garage sale, no manual however. Can I use it to power a 5.1 surround system for home theatre?


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

Trying to hook up 2 Hi Fi speakers to a reciever


Red left to Red left speaker
Black left to Black left speaker

then repeat for right speaker

turn on amp play somthing quite to start, check all is working. To check speakers are in phase play a bit louder and stand exactly in middle, bass should be defined and central, it helps to close eyes and listen. If not central and defined change over Red and Black on one side only then listen again with the same test.

Start flat with eq section adjust as you like when listening to something you know and like.

After all is working ok then make it louder.

Sorted!

Nakamichi AV10. Re: left channel softer than the right one.


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

Nakamichi AV-10 loud thud from subwoofer


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.

Nakamichi AV-10 very little sound on the center speaker


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.

Nakamichi receiver AV500


Did you make sure your Speaker A or B switch is pushed in? This happened to me a few times where I thought the receiver was broke, but someone had accidentally turned of the speaker A switch...
