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.\u003c\/p\u003e\n\n\u003ch3\u003eKey Capabilities\u003c\/h3\u003e\n\u003cul\u003e\n  \u003cli\u003eFour ceiling speakers powered and fed from a single network connection.\u003c\/li\u003e\n  \u003cli\u003e4x4 mix matrix lets any Dante input reach any of the four amplifier outputs.\u003c\/li\u003e\n  \u003cli\u003ePer-output DSP covers gain, filters, dynamics and delay for room tuning.\u003c\/li\u003e\n  \u003cli\u003eAmplifier is Class D, 20 Hz to 20 kHz ±1 dB into an 8 ohm minimum load.\u003c\/li\u003e\n  \u003cli\u003e4 in paper-cone drivers, 135° conical coverage, 106 Hz to 20 kHz range.\u003c\/li\u003e\n  \u003cli\u003eRemote status monitoring and control through an Extron IPCP Pro xi control processor.\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhere It Is Used\u003c\/h3\u003e\n\u003cp\u003eLarger classrooms, lecture rooms, boardrooms and open areas that need four ceiling positions for even coverage.
