Power indicator.
In case the backlit Edit display isn’t enough assurance, this yellow indicator glows anytime adequate power is
applied to the SRM 66, alerting you to its

Internal 80 Hz High Pass Filters
Each Output of the SRM 66 features an internally switchable 80 Hz highpass filter. These filters roll off low frequencies. This
is useful in small sound reinforcement systems or for use with constant voltage line transformers. These switches are shipped
from the factory in the OUT position. If you wish to enable any or all of the filters for each Output, it will be necessary to
remove the unit’s top cover before installation. Locate the switches near the center of the board, as shown below. S2 = Output 1,
S4 = Output 2, S6 = Output 3, S8 = Output 4, S10 = Output 5, and S12 = Output 6.
