RKB-650 Six Channel Power Ampliﬁer NOTE: You can remove the feet from the bottom of the ampliﬁer if necessary for clearance in the rack. Save the feet and hardware for future use.

English 9 Circuit Breaker A 16 amp circuit breaker on the rear panel protects the amplifier’s electrical circuity. Generally, the circuit breaker will only open under a fault condition which results in excessive current draw. To reset the circuit breaker, press the button. Should it repeatedly open, contact your authorized Rotel dealer for troubleshooting assistance.

RKB-650 Six Channel Power Ampliﬁer Speakers The RKB-650 has three groups of speaker connectors, one for each pair of ampliﬁer channels. Speaker Selection The nominal impedance of the loudspeaker(s) connected to the RKB-650 should be a minimum of 4 ohms. When driving multiple pairs of speakers connected in parallel, the effective impedance the ampliﬁer sees is cut in half. For example, when driving two pair of 8 ohm speakers, the ampliﬁer sees a 4 ohm load.
