Parallel Connection Instructions
The Model 12 Mono Power Amplifier provides 200 watts of audio output power, sufficient to drive nearly any loudspeaker. In a few instances, there may be a need for more output current in order to drive a very low impedance or current demanding loudspeaker. The Model 12 Mono Power Amplifier offers a unique solution for owners of the Model 12 who feel that they need more power or would like to increase the sound quality of their audio system: parallel connection of multiple amplifiers. Operating multiple pairs of Jeff Rowland Design Group Model 12 Mono Power Amplifiers in parallel will improve sound quality and:
∙Provide greater current output capability to increase the amount of amperage available at any given time to meet loudspeaker current demands. Assuming that a loudspeaker will draw large amounts of current for a particular output level, the amplifiers will have no problem delivering what is asked of them.
∙Parallel configuration of the amplifiers means that a greater number of output devices are used. As the number of output devices is increased, the portion of the audio signal that each device is responsible for passing is decreased, meaning that each device has less work to do. This results in better sound quality.
A greater number of Model 12 Mono Power Amplifiers can be paralleled for increased current capabilities and sound quality. In situations and systems where parallel connection of amplifiers is desired, an additional balanced interconnect and an output jumper will have to be obtained to connect the inputs and outputs of each amplifier. These jumpers should be sourced from the manufacturer of your loudspeaker cables. To ensure that the cables have been properly constructed and will provide optimal performance, please contact your loudspeaker cable dealer or manufacturer about having a set of jumpers manufactured to the specifications of Jeff Rowland Design Group. We will gladly provide the instructions or a pattern for any necessary cables.
