The iKON iK42 is an advanced 4 channel power amplifier which combines very high power density with superb audio performance, state of the art DSP and network control. A dedicated controller amplifier for Martin Audio Wavefront Precision line arrays and XE Series stage Monitors, the iK42 can also provide multi channel amplification across the Martin Audio loudspeaker range. The iK42 can deliver a full 5000 watts per channel into 2 ohms with all channels driven while remaining highly efficient. Its high efficiency reduces the energy drawn from the mains supply and ensures the power reserves needed to deliver superb sound under arduous live conditions. Ethernet is used for system remote control and monitoring via Martin Audio’s VU-NET software application, while a userfriendly front panel interface allows full local control of all features. Dante digital audio network inputs are also provided for digital audio distribution and control. 96kHz DSP is fully integrated into the iK42 to provide a multitude of features, including LIR linear phase crossover filters which have lower latency than FIR filters. The iK42 employs comprehensive protection functions to maintain safe operating conditions of both the amplifier and the loudspeakers driven including a sophisticated loudspeaker limiter suite which incorporates peak, RMS and excursion limiting, as well as multiband limiting for passive 2 way systems
