Details

Extron XPA U 4004 FX (part number 60-2034-01) — a four-channel Class D power amplifier that drives 8 ohm, 4 ohm, 70 V and 100 V loads from a single 1U rack frame.

Most multi-zone rooms mix load types: low-impedance speakers over a conference table, a constant-voltage line feeding overhead speakers down a corridor. This amplifier handles both without outboard transformers. Each of its four outputs is rated 400 W with every channel working, and when one channel in a pair carries the load alone it can reach 800 W — headroom for a zone that needs more than its neighbors.

Key Capabilities

Four amplifier channels rated 400 W each with every channel driven, into 4 or 8 ohm, 70 V or 100 V loads (1 kHz, 0.2% THD).
Up to 800 W from one channel of a pair when the partner channel is not carrying load.
Audio performance of 20 Hz to 20 kHz ±1 dB, 100 dB unweighted signal-to-noise, and 0.1% THD+Noise measured 3 dB below clipping.
A switch-selectable 80 Hz high pass filter with 12 dB per octave rolloff for 70 V and 100 V operation.
Four 3-pin 3.5 mm captive screw inputs at +4 dBu nominal, plus a 2-pole control port for contact-closure standby.
Protection covering clip limiting, thermal events, short circuits and DC at the output, with LED indication.

Where It Is Used

Divisible ballrooms, lecture halls, houses of worship, hospital and clinic paging systems, retail floors and transport concourses — anywhere one rack space has to feed several speaker zones that do not share the same impedance or distribution voltage. Rear rack ears accommodate rails set 15.48 to 26.13 inches apart.
