Details

Extron NF 4C LP-4 Package (part number 42-337-43) — the fully loaded kit: one PoE-powered NF 4C P LP driving three passive NF 4C S LP speakers.

This is the largest configuration the powered speaker supports, and it uses every one of the amplifier's four channels. Audio and power still arrive on one RJ-45 connection. Loading all four positions costs some headroom, so the PoE class matters more here than in the smaller kits: 87 dB SPL at one metre on 802.3af, 89 dB on 802.3at and 93 dB on 802.3bt, using default DSP filters. Specifying a PoE++ switch port is the straightforward way to keep the full output available.

Key Capabilities

Four ceiling speakers powered and fed from a single network connection.
4x4 mix matrix lets any Dante input reach any of the four amplifier outputs.
Per-output DSP covers gain, filters, dynamics and delay for room tuning.
Amplifier is Class D, 20 Hz to 20 kHz ±1 dB into an 8 ohm minimum load.
4 in paper-cone drivers, 135° conical coverage, 106 Hz to 20 kHz range.
Remote status monitoring and control through an Extron IPCP Pro xi control processor.

Where It Is Used

Larger classrooms, lecture rooms, boardrooms and open areas that need four ceiling positions for even coverage. Voice-lift and program-audio duties are both handled, and the whole zone remains addressable from the network for monitoring.
