I have been using my amp for only two weeks and last night it just decided that the range of the remote (one that came with receiver) is only extending out one inch. All the receiver functions on remote work well when I hold the remote no more than an inch from receiver's sensor. All the obvious has been accomplished batteries, cleaning lens etc. The funny part is the other programmed components (DVD, TV) on the remote work fine from distances of 15 feet. I am hoping it's the remote and not the receiver. Any suggestions?

check your amplifier output speaker impedance requirements.. example: 8 ohms...build a speaker 8 ohms in parallel or series connection.. check the impedance using ohmeter ..you must reach the required impedance..
use 1 cell battery to check if you speakers are in-phase...if one speaker did not ..reverse connection and check again ...to give the good sound...hope you understand my english..:)
HI , just found your post . I also have just picked up a denon DAP-2500 pre and 2 POA 4400 amps with klipsch belles, having same probs with power balance i followed some helpfull advise and deoxidized all rca jacks speaker terminals ect. also i opened the pre amp and cleand it even though it was fairly clean, i used cleaner on all switches and volume controll's . WOW I could hear it nice and clean . Next i will clean the amps. hope this works for you as this is great equpment well worth saving.
You have a bad amplifier section and your unit will need to be repaired by a technician. I would disconnect the speakers to prevent possible damage. In some cases components in line with the transistors will be bad in the amplifier also. There is no way to tell without electrically testing the unit in shop. Estimated repair cost would be in the 60 to 80 dollar range depending on the number of parts that are bad and the labor rate in your area.
Did you replace all tubes preamp and power amp? Just a clarification I assumed so. Some common problems with amps in general are after time the effects loop relay can be going bad. This happened on my 5150. I eventually replaced the relay and all was fine but until I did I used a patch cable to go from send to return. Unfortunately this amp employs the use of opamps in its signal path for the EQ. You may also what to check these. First try the effects loop patch to see if that works for you. Since the problem is intermittent it sounds like that is the problem. If you need any other help let me know, I have pretty good experience troubleshooting/building tube amps.
i had the same ploblem with my amp then i found out i didnt have a good enough ground. Make sure you groung it to your weel well or some part of the frame. Or you mite be running with a fuse thats pushing to much power i use a 100a fuse 5 gage power cord to power my 1200w xplode and my 2 12" kicker comps. Or if your using two diff kind of subs then you amp is confused in why your asking for 500w on one side and 600w on the other this will also make your amp light come on.
I've worked on similar units. Things I'd check first : Dust in the unit. Weak solder connections /crusty debris stuff on the input jacks or output terminals Any flex cables soldered in tend to be a problem on peavey amps I resolder all those contacts. Checking the amp w/o a load IS NOT a good suggestion. What style output connections are you using? 1/4 inch, binding post, or Neutrik style?
You can use the amp stand alone. The remote connection turns the power amp on and off. I would connect it to +ve12v via a switch on the control panel of the boat. Turn on the switch when you want to use the amp. Good luck and happy punting!
