19" rackmount 2U power amplifiers with dual fan cooling and class H architecture for safe, reliable power delivery. Balanced inputs via XLR sockets, speaker outputs on 2 SPK connectors or 4mm binding posts. High power output stable down to 2 Ohms load per side can also be bridged mono to 4 Ohms. Switchable ground lift, bridge mode and clip limiter.Power supply[tab]230Vac, 50Hz (IEC)[br]Controls[tab]Level channel 1, level channel 2, ground, mode, clip limiter[br]Input impedance[tab]20k ohms[br]Frequency response[tab]5Hz - 50kHz[br]Total harmonic distortion[tab]0.05%[br]Slew rate[tab]40V/us[br]Damping factor[tab]>400[br]Protection[tab]Short-circuit, overload, D.C. and thermal protect[br]Dimensions[tab]482 x 453 x 88mm (2U)Power rms @ 2 Ohms[tab]2 x 1800W[br]Power rms @ 4 Ohms[tab]2 x 1350W[br]Power rms @ 8 Ohms[tab]2 x 800W[br]Power rms bridge @ 4 Ohms[tab]2900W[br]Power rms bridge @ 8 Ohms[tab]2300W[br]Weight[tab]26kg[br]Fuse[tab]F15A (6 x 32mm)[br]Amplifier : construction[tab]Class-H
