Details

Extron NetPA U 4004 FX (part number 60-2035-01) — a four-channel, fan-cooled Dante power amplifier with software-configurable output modes.

Each of the four channels in this 1U, full-rack chassis can be set independently to 4 ohm, 8 ohm, 70V, or 100V operation, and adjacent channel pairs can share power to deliver up to 800 watts on one output when a zone needs more headroom than the standard 400 watts per channel. Dual Gigabit Dante/AES-67 ports bring in up to 8 channels of network audio, while variable-speed fan cooling lets the amplifier handle sustained high-power operation that a convection-only chassis could not.

Key Capabilities

400 W per channel across 4 channels, or 800 W when pairing channels for shared power
Independently configurable per-channel output: 4 ohm, 8 ohm, 70V, or 100V
Dual Gigabit Dante/AES-67 network ports carrying 8 Rx / 8 Tx audio channels
Variable-speed fan cooling rated for full-rack, high-power duty cycles
PoE-powered DSP/controller stays live even without AC present
Extron DSP Configurator Pro, SIS, and internal web page control options

Where It Is Used

The mixed-impedance, configurable-per-channel design fits venues that combine direct-drive stage or AV-zone speakers with 70V/100V paging on the same rack — houses of worship, auditoriums, ballrooms, and large conference centers where a single amplifier needs to flex between zone types.
