1

Power LED —

Lights when the PA 250 is on.

2

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.
