I just purchased a Caliber 22 power amp.
I have a guitar USB interface what is connected to my laptops USB port and I am using a software to play with various effects.
When I plug the instrument cable into the Calibre 22 input coming from the output of the USB guitar interface the Caliber 22 cuts out immediately. If I plug the guitar straight into the Caliber input it works fine, but on bigger volume it cuts out. I am using a 100watt 8 ohm speaker cabinet.
Could anybody advise me what could be the solution to connect the USB interface to the power amp? I have two USB guitar interfaces and the same thing happens with both of them, when I connect them to the power amp immediately cuts the sound off. I was trying to put the volume down to zero on both interfaces, but the same thing happens every time the Calibre 22 cuts out.
I suppose it has some kind of overload protection but I can not imagine that the outgoing signal wold be so huge from the USB interface.
I do not want to play with it because I might stuff it up.
Any help would be appreciated.
Hi, I bought a magnum 44 and tested it with four different cabs, 2 are 8ohm and other two 16ohm.
With 16ohm cabs no problem at any volume, but with both 8ohm cabs when I put it loud it goes in cutoff protection.
Tested with guitar only and preamped as well, same thing appen just at higher volume.
I don’t know if mine is defected, I guess yes otherwise is a big problem to work with 16ohm cabs only.
