Connecting the Speakers
■ Phone Plug Wiring
Phone plugs for connection to the phone jack inputs should be wired as
shown to the right. Be sure to use proper speaker cable — NOT shielded
instrument or line cable — for all speaker connections.
■ Neutrik Speakon NL4FC Plug Wiring
If you will be using the Neutrik connectors for speaker input,
wire the plugs as shown to the right. Be sure to use proper speaker
cable — NOT shielded instrument or line cable — for all speaker
connections.
■ Full-range Connection
Each speaker (except for the C112VA/ C115VA) features four input/parallel connectors—two 1/4” phone jacks and
two Neutrik Speakon NL4MP connectors. Use either a phone jack or a Speakon 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).
Impedance Considerations
When connecting speakers in parallel be sure to check the rated load impedance of the power amplifier. Most power
amplifiers are capable of safely driving speakers with minimum impedance of 8 ohms or 4 ohms. A pair of paral-
lel-connected 8-ohm speakers have a total impedance of 4 ohms. Two 8-ohm speakers can safely be paralleled on one
output. 4-ohm speakers, however, should not be parallel-connected with other speakers. These models can be con-
nected in parallel, however, if you are using a power amplifier that can safely drive load impedances of 2 ohms or
lower. Check your speaker impedance on page 7.
