Amplifier Troubleshooting
System Protection
Each Evolution One amplifier has a built-in DC monitor that continuously moni-
tors the audio signal at the input, as well as other sophisticated protection cir-
cuits that monitor other areas of the topology, in order to safeguard the amplifier.
This circuitry constantly evaluates the operation of the amplifiers and provides
protection against potentially damaging DC input or output and short circuits.
Regulator operation is also continuously monitored to ensure constant voltage to
the output stage. These protective systems are designed to prevent damage to
Evolution One amplifiers or loudspeakers caused by other defective components,
faulty wiring, system mishandling, or amplifier failure.
