What is the difference between Model 301's parallel and series output configuration?

The Model 301 monoblock power amplifier can be configured for the best possible interface with any reasonable loudspeaker load or design. Two configuration options are available: parallel and series. The parallel configuration provides high current capability, while the series configuration yields high voltage capability.

  • The parallel output configuration provides superior current capability, low output impedance, and greater damping factor into low-to-medium impedance loudspeaker loads. This configuration is designed for dynamic loudspeakers that have a nominal impedance rating ranging from 2 ohms to 8 ohms, ribbon based loudspeakers, and select electrostatics or hybrid loudspeakers.
  • The series output configuration provides superior voltage capability and high output impedance into high impedance loudspeaker loads. This configuration is designed for dynamic loudspeakers that have a nominal impedance rating greater than 8 ohms but not higher than 16 Ohms, select subwoofer systems, and select electrostatic or hybrid loudspeakers.

If you are unsure of the type or specifications of your loudspeaker system, it is highly recommended that you contact your speaker dealer or the manufacturer of the loudspeaker prior to making any amplifier connections. This will allow you to select the optimal connections prior to power being applied to the system. If you are still unsure of the proper output configuration for Model 301, please contact your Jeff Rowland Design Group dealer.
