Power LED —
Lights when the PA 250 is on.

Level control —
Adjusts the amount of compensation for
amplitude losses caused by cable resistance.
3
Peaking 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.
