Trs good amp made in United States (not like the XLS series made in ...)
In turn the bridg knob Track 2 ZrO! is not marked so ...
XLR connector plate (crown or house) can be easily added in front rear.
Be careful to leave space on the flight case if cots home!
Components "solid" (capacitors and transformer philips wide strip of copper!
Long life if: all the ignition knob 0 / stop and 4 ohms in Stereo mini (8 ohms in Bridge) I have not tried the method parrallle but I think careful!
