TRIDENT PROTECTION CIRCUITRY

Your Human Reign Unleashed amplifier is protected against both overheating

and short circuits by means of main power fuses and the following circuits:

Speaker Output Protection

Ground Fault Differential

Smart Power Supply Thermal Rollback & Thermal Protection Circuit

NOTE: If you experience blown main power supply fuses, it is likely that the amplifier is seeing a dead short, either in the speaker wire or in the speaker itself. Rectify the problem before blowing multiple fuses!

DO NOT increase values beyond the original fuse value! Doing so will void your warranty and may damage your amplifier
