This version of NL4MP (4-pole Speakon panel mount, in D size) differs, in that you get screw terminals on the rear.
This, of course, makes the total depth a little greater.
If you’re front mounting, allow 30mm at the rear. Should you be rear mounting, you’ll need to leave areound 35mm.
NL4MP-ST is a 4 pole chassis connector, black D-size flange.
Countersunk thru holes, screw termination.
This chassis connector is not airtight.
The speakON panel mount connectors are the standard chassis connectors for loudspeaker / amplifier interconnections. They feature a unique metal locking system, making contact only once fully locked. The speakON receptacles are robust, versatile and easy to terminate.
