Wiring of SpeakOn connectors:
|
| SpeakOn connectors find their application in, mostly, more-way speaker systems. The biggest manufacturer of these connectors is Neutrik. This manufacturer also developed a "standard" which is abided by most (not all) speaker manufacturers. This standard is as follows: |
| Recommended wiring: General: |
"+": in phase (high)
"-": ground (out of phase, low)
Lower numbers for lower frequencies |
| AMPLIFIERS: |
| Stereo ("Hi-fi"): |
One (1) socket NL4MP |
| left channel: pin 1+/1- |
| right channel: pin 2+/2- |
Power ("PA"):
"A" Socket (left):
"B" Socket (right):
"M" Socket (middle): |
Three (3) sockets NL4MP |
| Channel A (channel 1): Pin 1+/1- |
| Channel B (channel 2): pin 1+/1- |
| Channel A: pin 1+/1- |
| Channel B: pin 2+/2- (same as HiFi-Stereo) |
| Bi-Amp: |
One (1) socket NL4MP |
| LF: pin 1+/1- |
| HF: pin 2+/2- |
| CABLES: |
| Stereo ("Hi-fi"): |
4 conductor cable, connector NL4FC at amplifiers end, split into two pairs and terminations at Speakers end as requested |
| left channel: pin 1+/1- |
| right channel: pin 2+/2- |
| Power ("PA"): |
| Standard: |
one two conductor cable for each channel with NL4FC on both ends, wired to pins 1+/1- |
| Bridged Mono: |
Special cable, 2 conductors with NL4FC's on amplifier end, wired to pin 1+/2+, other end depending on application |
| Bi-Amp: |
Two standard cables on one 4 conductor with NL4FC on both ends |
|
| SPEAKER SYSTEMS: |
| Full range systems: |
|
NL4MP (-R), pin 1+/1-. Positive signal to pin 1+ produces positive waveform from driver(s) (moves cone outwardly). |
| Sub-Woofer: |
|
NL4MP (-R), pin 2+/2- |
|
| Note: We haven't been able to locate the recommended wiring for 8-pin SpeakOn connectors. Most probably the rules of the NL-4 connectors apply here also. |
