This allows you to select the correct amplifier output impedance for the particular speakers you have connected, Proper selection insures the best efficiency, response and prevents potential damage to speakers or the amplifier, Refer to page 17 of this manual:

The very FIRST thing to check is to make certain ALL of your speakers have an IMPEDENCE of 8 OHMS. Virtually all speakers of even modest quality will include this specification on a label on the back of the speaker. You CANNOT run more than (2) TWO speakers with 4 OHMs impedence on ANY amplifier (technical discussion too long!) [NOTE: Even though fused, your receiver has internal overload protection systems to prevent permanent damage. However, you cannot re-set these systems yourself. Your dealer or authorized service center must do this.] But, before you take it in for service, there is one more "test": check for shorted and/or mis-connected/disconnected speaker cables/wires. Visually inspect connections at the receiver and speakers first. You might find something obvious! If everything looks okay, then disconnect ALL of the speakers; and reconnect and test them one at a time (at relatively low volume.) For example, reconnect the left front speaker, test the system; THEN add the right front, test the system,and so on, ADDING one more speaker each time - FIRST MAKING SURE EACH OF THEM HAS AN IMPEDENCE OF AT LEAST 8 OHMS! IF there is a short (or bad speaker) this will help isolate it. Hopefully one of these "fixes" will work for you. GOOD LUCK!

over load means your speakers and its cable----please check it for bad cable or bad speaker------try to insert speaker one by one and test each time to investigate the bad one.--------if every thing is ok and you keep good ventilation around your receiver (no blocking of ventilation holes)and you still have a problem your protection circuit in your receiver needs to be checked by service technician

SOURCE: technics sa-ax730 won't play a&b speakers at same time.

Low imp probably means "Low Impedance". You've got either too many speakers hooked up in parallel on the same binding posts or spring contacts or the single sets of speakers on A & B are low impedance to begin with (i.e. 4ohms).

When you switch between A, B, and A + B, the last setting just puts B in parallel anyway.

Too low an impedance means higher current and the receiver may not be capable of handling it. Check your owner's manual for recommended speaker impedances.

If you test with a single set of speakers, switching the actual cables from A to B should work (even at a nominal 4ohms). If that's the case then you will need a different set or sets or speakers to hook up to B. If it doesn't work at all and still says "low imp", test with a known higher impedance speaker (i.e. ~8ohms).

If none of that works, you're on your own.

Good luck in any case.

How should I connect my Technics SA-AX730 receiver to my Panasonic TC-40A420U that uses HDMI?


I assume the Panasonic is a TV. I have never heard of green audio outputs. Audio outputs should be red and white (for RCA plugs). There are adapters available that convert the yellow, red and white component outputs to HDMI. You can get them at GameStop (I bought one recently to connect a game system for my daughter). If you have a TV converter box from your cable or satellite provider you might be able to connect the audio out on the cable box to your Technics receiver and run a HDMI to the TV (be sure to turn off the TV's internal speakers through the TV's menu) for video.

Technics sa-ax730 won't play a&b speakers at same time.


This is similar to protect mode in that the amp has detected a short in the output and has shutdown to prevent damage. Without seeing the unit, I'm a bit hesatant to suggest repair tips. At this point, I would suggest you get a detailed estimate from a local shop. We should be able to guide you through the actual repair once the results are posted here.

I have a Technics SA-AX610 receiver that says overload .


From the manual pg 27....... "The protection circuitry has functioned because the positive and negative speaker connection wires are "shorted," speaker systems with an impedance less than the indicated rated impedance of this unit are used or under severe use, such as loud volume, excessive power and in an excessively hot environment."

Video Problem


You most likely have either bad connections from the jacks to the main PC board or the video switching chip has an internal problem. Try resoldering all of the input jacks first and update this with your results.

Your speakers are way tp powerful you should only use speakers just over what the amp is rated at the most and check your impedance is not lower then 6 ohms and turn the bass to half way i am using 60 watt bookcase psb speakers and they work just fine and they pound no problem
