1. powDR swITcH & INDICATOR. Electrically speaking (as oppos€d to politically or financially) this conlrols the
power
to rh€ ME 60 (as opposed to the people). The yellow LED Iights any time this switch is closed and power has, in fact, actuallv
flowed into the ME 60.
2. FTLTER LEVEL CONTROLS. These stide controls set rhe individual levels for each ofthe consianrQ filters. Th€ir range is
+t2dB, and the grounded center-derent design ensures individual filters are offand bypassed when positioned to their centers
3. LO CUT FILTER CONTROL. Sets th€ comer frequency (-3dB point) for the low cut filter (high past. Adjustable ftom
10Hz to 250H2.
