ENGLISH Connection Examples ■ Full-range Connection Each speaker features three input/parallel connectors - two 1/4" phone jacks and one Neutrik NL4MP connector. Use either a phone jack or the Neutrik connector to receive input from your sound system/power amplifier. One of the spare connectors can be used to parallel-connect an additional speaker (keeping in mind the impedance considerations mentioned below).

Two parallel-connected 8-ohm speakers have a total impedance of 4 ohms, which is the minimum that should be connected to one amplifier output channel. The R112/R112C, R115/R115C, R12M/R12MC, R15M/R15MC and R118W/R118WC are 8-ohm speakers, and two of these can safely be paralleled on one output. The R215/R215C, however, has an impedance of 4 ohms and should not be parallel-connected with another R215/ R215C or any other model. 4
