Equipment being used.
TLAH Pro 8 ohms x 2
T48 15LF loaded
QSC RMX1850 DCX2494
BEHRINGER Mixer
15 band EQ
The amp clips constantly and cuts out intermittently at high volume with singers and keyboard in a church setting even though the mixer is not clipping. If the mixer is turned down to prevent the amp from clipping the overall volume will be too low. Any ideas as to how to solve this problem?
Power amp cutting out. Why?
Re: Power amp cutting out. Why?
There could be a short in one of the speaker cables or cabs?

Re: Power amp cutting out. Why?
Without clipping the output of the mixer, your output gain from it could well be to high for your amp and clip it.
Could still be asking to much of your setup. I dont know how big the church is, but the 300w into your titan might not be enough to fill a big room.

Also, if you increased the output and input gains on the DCX in order to balance the TLAH's with the T48, set them all back to 0 and use the limiter on the TLAH output channel to balance instead. This also frees up the CPU somewhat in the DCX. As does removing any EQ and using your 15 band for that job.
50V @ 10 ohms = 250W, so 300 should be ample. I can't see a church wanting a T48 at war volume, but if there is only one and the church is large, I can see your point.Bas Gooiker wrote:Could still be asking to much of your setup.

99% of the time, things that aren't already being done aren't being done because they don't work. The other 1% is split evenly between fools and geniuses.

Which side is clipping and cutting out? I assume you are using one channel of the RMX1850 for tops and one for subs?CT wrote:Equipment being used.

Re: Power amp cutting out. Why?
The side. running the tops is clipping. After looking at the setup closely it appears that I was driving the amp inputs with too much levels from the EQ.Zarunning ngock wrote:Which side is clipping and cutting out?

Re: Power amp cutting out. Why?
I discovered that on my Crown XTi1000, when I clip my sub output, the top output distorts through my top speakers. The top channel is not clipping. Weird. I have no idea if the sub is distorting, the Titan doesn't sound any different and I don't expect any of the noises to be able to come through the folds.

Re: Power amp cutting out. Why?
Probably the power supply is hitting its limits, and that reduces headroom in the other channel as well.Gauss wrote:I discovered that on my Crown XTi1000, when I clip my sub output, the top output distorts through my top speakers.

Re: Power amp cutting out. Why?
Did you check the wiring on the Tlah? The resistance load of the array?
