Sound quality change


One of my speaker wires came loose and made contact with the other while running. It popped and went dead. I turned the HK amp off repaired the wire, turned on the amp and crossed my fingers.I've got pretty good sound but it seems to lack the incredible headroom and midrange it had before. Is this a problem with the speakers or my amp and what can I do about it?

Re: Sound quality change

Let me see if I am understanding this.Somehow one chanel of your HK amp was shorted ,But only for an instant.When the wires touched we are hoping that the protection circuitry shut down the HK amplifier . Here are some things you can check:

  1. First and most likely thing: is there any chance that you reversed the speaker leads and now the speaker is playing out of phase from the rest of the system.
  2. You can check and see if it is the speaker or the amp by putting one of the other speakers in the system in that same spot, but make sure that speaker is in phase as well.
  3. Run the channel you think you may have damaged through one of the good speakers that you know is not damaged.
If you set two speakers together, while they are playing they should be beating in and out at the same time. If a speaker is out of phase while one goes in the one that is out of phase will go out and vice versa.

If you still have not narrowed down the problem, there might be a problem with the amplifier itself. For future reference, if I have an amp and speakers that I like, I will put a small fuse right at the point where the wire comes out of the amp: put it on the +(hot) wire. If you have any more questions feel free to ask or myself.

If this helps you with your problem, please let us know.

Hk990 left channel dead

It is unlikely that your have a damaged amplifier. You may have something switched wrong. In your owner's manual, you will find a procedure that says' "Return to factory defaults, or just reset". If that doesn't resolve your issue, or you need more assistance, or would like to inquire about a repair, please visit my website at You may contact me there. BTW, I worked at HK. Thank you.

Hi guys. Having a problem with my NAD T163 Surround Sound Decoder. Popping in front left and right speakers when changing audio selection. Works well other than that. Please give me some suggestions w

Could be DC voltage on the speaker output line, but this will generally keep your receiver audio output turned off completely. Could be a bad muting transistor or microprocessor IC(computer within your NAD). If you are interested in having your NAD repaired, please visit my website at may contact me there. Thank you..

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.

How are you? For HK990,How to do bi-wiring connection of the speakers? thanks

Sabve your money - it's BUY-wiring.

Bi-wiring does nothing but make you use twice as much speaker wire for the same electrical effect. Bi-amping assumes there are deficiencies in your electronics that must be worked around, again by using more speaker wire and separate amps.

Do some reading on the web about "bi-wiring".

I use an azur intregrated amp 540A and a Azur Pre amp 640P. When first power up, The amp makes a popping sound and the volume turns down. Some times it can pop 2 or 3 times within a few minutes. Then it...

I've never repaired one of these but I have an amp at home that makes a intermittent static "popping" noise that i'm going to put down to a dirty volume pot (control) that needs cleaning. I will also have to change some of the electro capacitors that have dried up inside which cause "shot noise". With the right lubricant (electrical contact cleaner, nothing else) you could take to lid off and spray a small 1 second blast into the hole of the pot and any other balance or tone control yourself but I would take it to the electronics repairer to get the capacitors checked over.
My theory only
Good Luck!

Big POP from speakers when powering on.

look for any cold solder or component terminal lose contacts at the solder side of the P.C.B. particularly at the tone control preamplifier stages and power amp stages, if you find some lose contacts re-solder might solve your problem...
"WARNING" avoid short solders...

Fender Vibro King Pilot light out??

Hi superleaddud

MOst probable, is that an output tube went west(decrease in vol), and in turn popped the fuse(pilotlight went out). It is always a decent first bet that this is what has happened. You get generally 6 months out of a set out output tubes if you use the amp often, and at gig levels every week. I would first check and replace the fuse, and then the output tubes. GT 6L6GE are factory for that amp, and always a fair bet to use the same to replace them. If you cant extend to the budget for the GT's, then Russian made (Sovtek) Electro Harmonix make a decent quality tube that sound good in guitar amps. . Always replace them as a pair, and buy them gain matched. Get the Grove Tubes from a music store, and the Electro Harmonix from an amp repair specialist. Happy to answer any question you may have about the problem. Cheers. A FixYa rating is a great reward for my assistance to you.
