This shows if the amplifier has been correctly powered up and if any faults are pre-

sent.

ver frequency is set at 100Hz or below, this feature is designed to filter all mid to
high frequencies that only FULL RANGE speakers should produce. NOTE: Failure to
do so could result in speaker damage.

Set the crossover switch 2 to HP and turn this control to 65Hz or above when using

speakers smaller than 6”, this feature is designed to filter all low bass frequencies
that only SUBWOOFERS should produce. NOTE: Failure to do so could result in
speaker damage.
