Connections

Normal Connection

The LF-3215 has barrier strip screw termi- nals for connection. The terminals accept up to #10 AWG (5.3mm2) stranded loud- speaker wiring. Use the largest wire size and shortest wire length possible for the application. Observe the polarity markings and keep polarity consistent throughout the system for best performance.

Parallel Connection of Second LF-3215

The terminals marker SPK2 may be used to connect another LF-3215 in parallel. Con- nect the wires as shown in the illustration, at right. Note: If the LF-3215’s internal wir- ing has been modified in any way, this may not function. If this is the case, remove the terminal cup and verify the presence of the factory yellow jumper and blue jumper wires; remedy as required or have the loudspeaker serviced.

Individual Transducer Connection (requires modification)

The transducers are wired in parallel inside the enclosure. If individual trans- ducer connection is required, remove the terminal cup and remove the yellow and the blue jumper wires that are connected between the SPK1 and SPK2 terminals. Replace the terminal cup and mark the enclosure with a note of the modification.

Normal Connection Example:

Amplifier capable of driving 4 ohm loads

Parallel Connection Example:

Amplifier capable of driving 2 ohm loads

Individual Transducer

Connection Example:

CAUTION! Requires removal of terminal cup and removing both the yellow and the blue jumper wires that connect the SPK1 and SPK2 terminals.
