AC cord 

The Relentless amplifier is fitted with threaded terminals for its power connections, rather than the 
IEC connector found on almost all other power amplifiers. Your amplifier has been shipped with 
the appropriate power cord for the voltage and socket available in your region/country. We strongly 
recommend you have a licensed electrician connect your power cable, to ensure the connections are 
correct. 

Incorrect power connections will void your warranty and can damage your amplifier.

To connect the power cable, remove the two screws on the plastic cover that protects the AC cable 
terminal connections. Remove the nut on the amp’s positive terminal, place the spade ring of the 
positive (+) conductor of the cable over the terminal, then replace the nut. Tighten the nut firmly but 
gently with a 3/4-inch socket wrench. Use of excessive force on the socket wrench could damage the 
terminal. Repeat the process for the negative (-) and ground conductors, then replace the plastic cover 
and tighten the two screws down to secure it.
