Question about Technics SA-DX940

6 Answers

Problem with subwoofer and one off the speakers.

I bought the Technics Receiver SA-DX940 about four years ago. I have used only about eight times. When I used it before, the sub woofer sound wasn't coming on. I have tried everything I knew without opening the system and it could not be resolved.Couple of days ago the sound on the right speaker stopped coming. It is more or less a new receiver because I don't use it much. I don't know what to do. Does anyone has an idea of what should be done?

    What is IC, and do I have to open the system? The right speaker stopped coming out also.

First of all, tried to use another set of subwoofer.

If the sound is comming from both speakers, either connection is not correct /weakened or there is an issue with that particular sub woofer. You need to replace it.

If the sound is not comming from 2nd speaker on the other set, issue is with system ( Which seems to be a rare case )..

Do rate the solution.


Thanks for using Fixya.

Hi, Does it have warranty?
Try switching speakers connections to check if the problem is with the speaker or the unit.
Check if the speakers were compatible with the unit. I mean the ohms and watts ratings.

First off all remove all connections and connect it once again to check it is not due to loose connection .
Secondly in receiver test all speaker is working if it doesnot indicate your speaker . Mostly hardware fault . Need to open the speaker to check which component is burnt .

Hi

Kindly check the wiring on the back of the system. Also try to swap the speakers just to check the speakers.

HOW CAN I CONNECT A MIXER TO A TECHNICS SA-DX940 AV


I used the manual downloaded from http://www.manuals365.com/technics/sadx940.html

Try using the final stereo output of the mixer as the input to the CD or Tape or VCR inputs.and use the switches on the fromt of the DX940 as necessary.
The specificatios state input sensitivity is 27 mY so your mixer needs a low output..
No reason it shouldn't work.

I moved and cannot find manuel for sa-dx940 need instruction on how to reconnet wire to t.v. and speaker


The Technics SA-DX940 is made by Panasonic. The manua as a PDF is available here: http://service.us.panasonic.com/OPERMANPDF/SADX940.PDF . The directions for connecting the speakers start on page 14. The connection to the TV is on page 10. To use the SA-DX940 as just external speakers for your TV, connect either the digital audio out from the TV (if it has one) or the RCA audio out from the TV to the matching TV audio in on the SA-DX940.

I hope this helps.

Ratnesh, I have this same receiver and the fan only comes on at certain volume levels. Unfortunately I now live in an apartment and can very rarely listen to it that loud. I had the same problem for a little while until I thought about moving the receiver to the lowest shelf with nothing on top of it. This seems to have worked so far although it does still get quite warm. Good luck!

overload, usually means that is overloaded. i've had the receiver for about 4 or 5 years now and never had problems with it. It was sitting ontop on my tv for those 4 or 5 years, and i haver noticed it untill just recently, (when i bought a new tv and i had to get a stand for it, and i had to stick the receiver in it)that is runs very hot, very quickly; Maybe that is the problem you are having now, that the thins is older and maight be able to handle it as it id b4. Maybe you made some changes to your set up: new speakers, etc.
