To be honest it sounds as though your volume control needs a clean, try to find some switch cleaner (servisol or similar) remove the casing and spray into the volume control from behind the face plate as apposed to from the front. Rotate the volume all the way back and forth several times to clean the tracks, I have used deodorant in the past to achieve the same result but as this will leave a residue, probably not recommended as a permanent fix. Obviously do these actions with the amp switched off, otherwise you will at the very least annoy your neighbours with the loud volume.
Hi, Yes you should make adjustments.KEF makes very good products, however if you don't handle this you will have to replace or service it. 1 If the woofer is very close to you, relocate it further away. The reason being is that the lower the frequency the larger the wave form. The lowest waveforms will become louder. 2 Adjust the high frequency cut off to be at 80Hz. This should eliminate boom. Higher Sub frequency tend to muddy the sound. 3 The sub should have a subtle effect in music. So the relationship between it and the speakers it augments the sound of should be seamless. 4 If you are playing Rap or Reggie music and you like to play it loud. Add another sub into the system and locate it NEXT TO the KEF Sub. In this fashion the two subs will reinforce each other's energy. They will "couple" thus multiplying their energy considerably. Hope this helps, Best Regards, Mark
Looks like your volume control switch is not working on the left side, you can check it by tapping the knob on the volume control and sound will come out on left side.
The only way to get the sound again is to replace the volume control or pull out the volume control and open it up to clean the contacts in it.
Check the input cables from the source you are playing at both ends. Sounds like an input problem, not a speaker problem. Twist the RCA connectors as you push them in to make sure the connection is good.
I ran into the same issue with an AVR 7000 after it had been shipped to me. I took the cover of and found that the left and right amplifiers have a separate power plug into them. when I plugged to "bad" side back in everything worked great.
Harman kardon amplifire are known for that.specially AVR 7000
but sometimes this comes from poor wiring and using a wire that will not conduct better sound. Remember your wiring is very important.you may think your wiring is currect, better to double check. even if your connection is ok and the wire you are using are not better to produce quality sound you will not get sound from every speaker.
WAT BRAND SPEAKER AND RECEIVER?POSSIBLE OHM ISSUE?WAT IS THE IMPEDENCE ON THE AMP AND CENTER SPEAKER,.HAVE YOU TRIED RUNNING A 6?8 CHANNEL CONFIG?FOR EX.USING YOUR SOUND CARD THROUGH THE PREAMP AS A DSP. WHE PLAYED IN SHOP HE USESD CD? U USING SAME CONNECTION FROM THE SAME INPUY? OR IF LISTEN ING TO RADIO. SOMETIMES THE SINGNSAL IS NOT IN A DIGITAL FORMAT SO THE PPR LOGII C CANT PRODUCE IT.IT WOULD BE PLAYED ANALOGICLY.MEAN NO CENTER.
