1Power LED — Lights when the PA 250 is on.

2Level control — Adjusts the amount of compensation for amplitude losses caused by cable resistance.

3Peaking control — Adjusts frequency compensation. It is similar

to the sharpness control on a television. It compensates for the effect of capacitance of long cables. Use the symbol at the left as a guide for adjusting the control.
