Details

Extron NF 4C LP-3 Package (part number 42-337-33) — a three-speaker kit built around one PoE-powered NF 4C P LP plus two passive NF 4C S LP units.

Three ceiling positions, one network drop. The powered speaker receives Dante or AES67 audio and PoE on the same RJ-45 connection, then feeds the two passive units from its 8 ohm captive-screw outputs. Because the internal amplifier has four channels and a 4x4 mix matrix ahead of it, each of the three speakers can be given its own source, gain, filtering and delay. With PoE++ 802.3bt available the system holds 94 dB SPL at one metre; on plain 802.3af it settles at 88 dB.

Key Capabilities

Three-speaker ceiling zone with no amplifier rack and no additional network drops.
Independent DSP per output: gain, filters, dynamics and delay, fed by a 4x4 mix matrix.
Powered unit consumes at most 40.3 W on PoE++, 27.1 W on PoE+, 14.7 W on PoE.
Dante and AES67 transport, 24-bit uncompressed at 44.1, 48, 88.2 or 96 kHz.
4 in paper-cone drivers with 135° conical coverage across 1 kHz to 4 kHz.
Plenum-rated UL94V-0 enclosures, magnetic grilles, V-rails and C-rings included.

Where It Is Used

Mid-size meeting rooms, training rooms, classrooms and lobby areas where three ceiling positions give even coverage. The networked architecture suits campus and multi-building deployments managed centrally through Dante Domain Manager.
