Bridged, it produces a single 800 W channel into 8 ohms — the same figure Extron quotes for the subwoofer's continuous program handling, so the pairing is deliberate rather than approximate. Left unbridged it gives two 400 W channels into 4 ohms or 200 W into 8 ohms, useful when one subwoofer per side is planned. The amplifier occupies a single rack unit and runs without a fan.\u003c\/p\u003e\n\u003ch3\u003eKey Capabilities\u003c\/h3\u003e\n\u003cul\u003e\n\u003cli\u003eSF 10C SUB: 25 Hz to 160 Hz from a 10 in waterproof-coated paper cone driver.\u003c\/li\u003e\n\u003cli\u003eXPA 4002: two channels at 400 W into 4 ohms or 200 W into 8 ohms.\u003c\/li\u003e\n\u003cli\u003eBridged mode produces one 800 W channel into 8 ohms.\u003c\/li\u003e\n\u003cli\u003e1U full rack width amplifier, convection cooled, 9 lbs (4 kg).\u003c\/li\u003e\n\u003cli\u003e100 dB signal-to-noise ratio, 0.1% THD+N, patented CDRS ripple suppression.\u003c\/li\u003e\n\u003cli\u003eEcofficient Level 3: 30 W or less at idle, under 1 W in standby.\u003c\/li\u003e\n\u003c\/ul\u003e\n\u003ch3\u003eWhere It Is Used\u003c\/h3\u003e\n\u003cp\u003ePresentation theatres, worship spaces, boardrooms and fitness areas where the low end has to carry real energy and the subwoofer must remain concealed above the ceiling.
