No output from R surround speaker in Harman Kardon AVR 210

When running the tone test there is a very faint trace of sound from the R surround. I boosted the output to +10 dB (on the R surround) and there was a slightly louder but distorted tone but it really couldn't be heard unless you had your ear right against the speaker. This was the same situation for every mode and source.

Possibly unrelated to this is an audible hum from the unit when it is first turned on for about a minute. I presume something is warming up, but I imagine that either way, the hum shouldn't be there.

The amp that runs the R surround speaker is or has went out in the main amp! also switch speakers around to make sure that one is not blown!

Connecting 4 ohm speakers


I don't think it has anything to do with the impedance. The amp and speakers are well in the allowed limits. The only time this is a problem is if you connect an amp with a greater impedance then the speakers.
This sounds like something to do with the HK 990. It could have a fault on it. You could try listening with headphones if the HK 990 has a socket for them. If they have low sound, there's an electrical fault in the power amp of the HK 990.

I have a Harman Kardon AVI 200 ii, when i turn it on it turns on like 3secs and then it automatically it turns off, why is that?


It is going into protect mode. You may have shorted speaker wires, you may have an internal short in a capacitor either in the filter section, or those on the output.

It runs so hot why?


Possibly lack of ventilation or excessive volume through difficult speaker loads.

See page 6.

IMPORTANT: When connecting two pairs of speakers, determine the impedance of each pair

by looking on the back of the speakers, in your owner's manual, or by contacting your dealer or manufacturer.

You can listen to two pairs of speakers at the same time ONLY if the impedance of EACH speaker is NOT LESS THAN 8 Ohms.

WARNING: Do not play sets of speakers simultaneously except as recommended above.
Amplifier may overheat.

I own my harman kardon 620 amplifier for about 8 years. Now the sound from the speakers comes on and off intermittently. I have connected and disconnected all the cables to the speakers but it still has...


The problem is in the audio circuitry, there are bad solder joints on the board that need to be addressed, from your description it is a intermittent issue with the sound. Since this a high end unit I recommend a top audio technician to work on your amplifier, and I suggest not using the system until it is repaired because the risk to the audio output parts getting damaged is high and they are pricey.

I don't have any instructions so i don't know how to hook up my speakers and the t.v for surround sound i have a carver avr 100


You should be able to online to the manufacturer of your products and download manuals. However, I will try to help.

Connect the sound output cables from your DVD player including, left/right(white/red) as well as the Coax output/input if your DVD and your Carver each have this feature for enhanced sound on certain DVDs, and connect to the matching DVD inputs on your Carver.

Then, connect your DVD video output either by use of your RGB(RED/GREEN/BLUE cables or an S Video cable to your the matching video inputs on your t.v.

On the back of your Carver, you will find outputs for left and right speakers, connect to the left and right speakers with proper wire. Make sure that the 2 conductor wire is connected with the same side(polarity) on all speakers for the best sound quality.

You will also find rear channel left and right outputs on your amp, connect those to your rear right and left speakers.

Connect the center channel speaker to the center channel speaker output on your amp.

If your Amp has a sub-woofer output and you have a subwoofer, make the connections on that as well.

Test all of the speakers with a feature that many amps have on the menu using your remote, simply called test. if all speakers are connected correctly you will be able to hear each one as they are individually tested by the amp. Hope this helps out.

I have Harmon Kardon AVR 25 ii receivers and I have attached it to Bose 701 front speakers and three other Bose surround speakers and an subwoofer. All the speakers work except for right speaker, I need...


To locate the problem...a) Cable
Test if right cable is ok, by interchanging the rt/left cables.

b) Test Bose right speaker
Connect the Bose right speaker to HK's left channel. Works? Then Bose right speaker is ok.

c) Test HK's right output by connecting the left Bose speaker to HK's right output.
Does not work?
