I have HK AVR-120 receiver/amp and TS-5 surround speaker system. Second time now, resistors on amp audio board (front channels) have burned out. Amp is in open air with good venting. Never turn above 50% of max power. Have checked and have no shorts in speakers or speaker wire. Believe amp and speakers match at 8 ohm - still checking. Can't find ohm listing on any of the speakers. Will check amp when it comes back from the repair shop today. What would cause resistors on audio board in amp to fail?
I appreciate any suggestions.

On my yamaha 375 receiver if I connect digital or hdmi it disables the balance/bass treble etc but they work with anolog don't know if yours might be the same just abit strang if anolog doing it aswell
Front panel button engaged for 5 or 7 channel operation? Also check front panel rear surround speakers button is engaged. Should get you back to 7.1 unless you have changed the rear surround speaker setup for a 2nd zone, also be sure you have a 7.1 DSP setting enabled.
Most HK av receivers have pre amp out,power amp in with metal jumpers connecting them for the main or front channels. that would be the best place to hook up the EQ on a AV receiver. If your receiver doesn't have pre out, power in jacks , you can use tape monitor .record out playback in. The tape monitor option is best for stereo use , as the active EQ will charge all speakers in tape mode, possibly damaging other speakers.I run my 901 s with a seperate pre-amp,power-amp hooked up to my Denon AV receiver that way i can run in surround w/standard speakers
Offhand should work more than OK. Even if the 520 is only pushing 75watts per channel, you have 2 X for the front KSB-2.1 (left & right) plus another 75 for the Polk Audio center in addition to 250watts built-in amp of the Velodyne CT-150. What would be better is another pair of KSB-2.1 or comparable for the surround (another 2 X 75 and widening the separation).
Good luck and Thank you for using FixYa. Happy Holidays.
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: MOST HK equipment have internal overload protection systems to prevent permanent damage. However, you cannot re-set these systems yourself. Your dealer or authorized HK service center must do this.]
But, before you take this beast 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 left 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.
HK is among the best equipment money can buy, and their equipment is pretty much "bullet proof!" Hopefully one of these "fixes" will work for you. GOOD LUCK!
