One channel of my Qsc rmx 2450 power amplifier keeps cliping

Check your connection, and make sure it is not dirty, overheating will cause it to cut out.

All off, except The "Clip Limiter" Those should be on for your speaker protection.

Hello,

A common issue with the QSC RMX series amp is faulty volume pots, so i would recommend go this way first of all, let me know a bit more to improve help.

Disconnect speakers. With NO input, if clip light remains on, take in for repair as there is an internal failure. If reducing the gain and loudness keeps the clip off, then you are probably driving the amp too hard. This is common problem when the user "thinks" they need it louder but the amp speaker combination will not deliver louder. At this point, both the amp and the speakers are at risk of permanent damage requiring repair.

CLIP: red, to the left of each Gain control.

Normal indication: illuminates whenever the amplifier is driven beyond full power. The LED's brightness indicates the amount of distortion. Distortion that causes only brief flashing may not be audible.

During muting, the indicator fully illuminates. This occurs during normal "On-Off" muting.

Abnormal indication:

•Bright red illumination while the amp is being used indicates either thermal muting or a shorted output.

•If the amplifier overheats, the fan will run at full speed, and operation should resume within one minute. Allow the fan to run, and make sure the amplifier ventilation is adequate.

•A shorted or overloaded output circuit will cause excessive Clip flashing and possible overheating.

•If distortion is audible without a Clip indication, the problem is either before or after the amplifier. Check for damaged speakers or overloaded signal source. The amplifier Gain control should be in the upper half of its range to prevent input overload.

hi,
its with me. if u need the same contact me on my mail.

Hi.

Check speaker wiring. An amp final channel usually blows because of excessive draw from speakers. This often happens because one of the speaker is shorted inside or because of a wiring problem.
Also ensure that speakers are responding to specifications. Speakers that are out of the amp Ohms range will do the same thing in a while.

Naturally you can also blow an amp final by pumping volume to the max for a while. The transistors or the STK ICs in the final section will overheat and blow.

Sounds like an output going bad. Try to get some electronic contact cleaner and spraying on the circuit board. If its corroded this will help clean the circuit..

Got asilimar problemwit a behringer europower pmh 3000.

The Right channel began to crack up and drizzle now it seems completely dead.
Changed the cables both of input and seapkers , still the problem stays the same. Any suggestion before brigning for a month at the repair shop? And get out with a 200-400$ bill ?

i have a pyle pro 1000 watt max 2 channel mono and 2 channel stereo and when i get that thing loud the little red light cums on basically what i mean is that the amp on channel one is cooked i myself i wouldn't even use it y cause more damage
