Each of its four channels delivers 400 watts and can be independently set to drive 8 ohm, 4 ohm, 70V, or 100V loads, so one chassis can feed a distributed ceiling speaker zone and a low impedance subwoofer at the same time. Audio arrives over the Dante network or through balanced analog line inputs, and an integrated 12x16 mix matrix handles gain, filtering, dynamics, and delay before amplification. For integrators standardizing on networked audio, this Dante enabled amplifier consolidates DSP, routing, and amplification into one 1U device with AES67 interoperability.\u003c\/p\u003e\n\n\u003ch2\u003eProduct Description\u003c\/h2\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/ne_60203501_der7101nrr_dv23.jpg?v=1787774619\" alt=\"Extron NetPA U 4004 FX four channel Dante power amplifier with DSP, front and rear view\"\u003e\u003c\/p\u003e\n\u003cp\u003eCommercial AV system designers deploying a four channel Dante amplifier usually face a tradeoff between channel count, load type, and rack depth. The NetPA U 4004 FX removes that tradeoff by making output mode and power allocation software configurable per channel. Total power within each adjacent channel pair is shared, so a single channel can be driven to 800 watts when the paired channel needs less, matching the amplifier to actual zone loading rather than a fixed nameplate rating. A software configurable high pass filter, defaulted to 80 Hz with a 12 dB per octave rolloff, protects speaker transformer cores in 70V and 100V constant voltage modes.\u003c\/p\u003e\n\u003cp\u003eThe onboard 12x16 mix matrix routes any analog or Dante input to any amplifier output, Dante output, or analog line output, with the post-DSP line outputs processed separately from the amplifier outputs so downstream amplifiers can receive their own delay and level settings. Dante transport runs 8 channels in and 8 channels out at 24-bit\/48 kHz with Dante Domain Manager and AES67 support, and the two Gigabit LAN ports can be merged for single cable operation or split to keep control traffic off the audio VLAN. PoE on the LAN\/AT 1 port keeps DSP, Dante routing, and analog line I\/O alive if mains power is lost, and lets the unit be configured on the bench before installation.\u003c\/p\u003e\n\u003cp\u003e\u003cimg src=\"https:\/\/cdn.shopify.com\/s\/files\/1\/0603\/7982\/4364\/files\/ne_60203501_der0201nrr_dv23.jpg?v=1787774618\" alt=\"Extron NetPA U 4004 FX rear panel with speaker outputs, line I\/O, and dual LAN ports\"\u003e\u003c\/p\u003e\n\u003cp\u003eInstallation-side details matter in dense equipment racks, and this network power amplifier is built for them. Front-to-rear variable speed fan cooling means no empty rack units are required above or below the chassis, and front plus rear rack mounting hardware ships in the box for racks from 15.48 to 26.13 inches deep. Power factor correction and ultra low inrush current allow multiple NetPA Ultra FX units to be energized simultaneously without a power sequencer. InstaWake auto-standby drops the amplifier to standby after 25 minutes of inactivity and returns it to full power in under 50 milliseconds on signal detection, fast enough that program audio is not clipped at the head. Control integration is handled over IP or RS-232 with Extron SIS commands, two digital input ports, two digital output ports, and an internal web interface for logging and hardware configuration.\u003c\/p\u003e\n\u003cp\u003eIf your deployment does not require networked audio, the \u003ca href=\"https:\/\/creationnetworks.net\/products\/extron-xpa-u-4004-fx-four-channel-configurable-output-audio-power-amplifier-400-watts-per-channel\"\u003eExtron XPA U 4004 FX\u003c\/a\u003e offers the same four channel configurable output architecture with analog inputs only.

Output mode is selectable per channel. Any of the four channels can be independently configured for 8 ohm, 4 ohm, 70V, or 100V operation, which allows a single NetPA U 4004 FX to feed a constant voltage ceiling speaker zone and a low impedance subwoofer from the same chassis.\u003c\/p\u003e\n\u003ch3\u003eHow does power sharing between channel pairs work in a system design?\u003c\/h3\u003e\n\u003cp\u003eTotal power is shared within each adjacent channel pair, with 800 watts available per pair. If one zone in a pair requires more headroom than the other, the amplifier can be configured to deliver up to 800 watts to that single channel. Size zone loading against the pair budget rather than treating all four channels as fixed 400 watt outputs.\u003c\/p\u003e\n\u003ch3\u003eWhat is required to get audio onto the amplifier over Dante?\u003c\/h3\u003e\n\u003cp\u003eA Dante-enabled source device and Dante Controller software to make the subscriptions. The NetPA U 4004 FX receives 8 Dante channels and transmits 8, and supports Dante Domain Manager and AES67 for interoperability with third-party network audio devices. In an Extron-based system it pairs directly with a Dante-equipped matrix processor such as the \u003ca href=\"https:\/\/creationnetworks.net\/products\/extron-dmp-128-plus-at-12x8-prodsp-processor-w-dante\"\u003eDMP 128 Plus AT\u003c\/a\u003e or the \u003ca href=\"https:\/\/creationnetworks.net\/products\/extron-dmp-64-plus-c-at-6x4-digital-matrix-processor-w-aec-and-dante\"\u003eDMP 64 Plus C AT\u003c\/a\u003e.\u003c\/p\u003e\n\u003ch3\u003eHow should the two LAN ports be configured on a corporate network?\u003c\/h3\u003e\n\u003cp\u003eThe dual Gigabit ports are configurable. They can be merged so Dante audio and control traffic share a single cable drop, or split so Dante audio sits on a dedicated audio VLAN while control traffic reaches the AV control system on a separate network. The unit supports IEEE 802.1X, HTTPS, SSH, and SFTP, which typically satisfies IT security requirements for a device placed on an enterprise LAN.\u003c\/p\u003e\n\u003ch3\u003eDoes this amplifier need empty rack units above it for ventilation?\u003c\/h3\u003e\n\u003cp\u003eNo. The chassis uses front-to-rear variable speed fan cooling rather than convection, so no ventilation spacing is required and units can be stacked contiguously. The 1U full rack width enclosure includes both front and rear rack mounting brackets, and the rear ears accommodate rack depths from 15.48 to 26.13 inches. Washable, replaceable foam air filters are used, with replacements available as the Extron AFK 100 10-pack.\u003c\/p\u003e\n\u003ch3\u003eDo multiple units require a power sequencer?\u003c\/h3\u003e\n\u003cp\u003eNo. The NetPA Ultra FX design uses ultra low inrush current at power up and includes power factor correction, so multiple amplifiers can be energized simultaneously without overloading the branch circuit or introducing harmonic content onto the AC line. This removes a sequencer from the rack bill of materials on multi-amplifier installations.\u003c\/p\u003e\n\u003ch3\u003eHow is the amplifier controlled and monitored from an AV control system?\u003c\/h3\u003e\n\u003cp\u003eControl and status monitoring are available over IP or RS-232 using Extron Simple Instruction Set commands. Two digital input ports and two digital output ports allow the amplifier to respond to external triggers such as preset recall, and an internal web interface exposes hardware configuration plus plain-language CSV event logs for remote diagnostics. Configuration is performed in Extron DSP Configurator Pro.\u003c\/p\u003e\n\u003ch3\u003eWhat warranty and support coverage applies?\u003c\/h3\u003e\n\u003cp\u003eExtron covers the NetPA U 4004 FX with a 3 year parts and labor warranty, and the internal Extron Everlast power supply carries a separate 7 year parts and labor warranty.
