The DW-S9000 is a two-channel Class D power amplifier delivering 2 × 4,500 W into 8 Ω, or 13,500 W bridged, from a 1.5U chassis weighing 14 kg. It is the channel-count that matters here: two channels, each with the current capability to drive a large flown array hang or a bank of high-power subwoofers, rather than four channels sharing one supply.
