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: 230Vac, 50Hz (IEC)vbCrLfControls: Level channel 1, level channel 2, ground, mode, clip limitervbCrLfInput impedance: 20k ohmsvbCrLfFrequency response: 5Hz - 50kHzvbCrLfTotal harmonic distortion: 0.05%vbCrLfSlew rate: 40V/usvbCrLfDamping factor: >400vbCrLfProtection: Short-circuit, overload, D.C. and thermal protectvbCrLfDimensions: 482 x 453 x 88mm (2U)Power rms @ 2 Ohms: 2 x 1800WvbCrLfPower rms @ 4 Ohms: 2 x 1350WvbCrLfPower rms @ 8 Ohms: 2 x 800WvbCrLfPower rms bridge @ 4 Ohms: 2900WvbCrLfPower rms bridge @ 8 Ohms: 2300WvbCrLfWeight: 26kgvbCrLfFuse: F15A (6 x 32mm)vbCrLfAmplifier : construction: Class-H
