The iKON iK41 is an advanced 4 channel power amplifier which combines high power density with superb audio performance, state of the art DSP and network control. A dedicated controller amplifier for Martin Audio WPM line arrays, TORUS 8, and selected other systems, the iK41 can also provide multi channel amplification for select Martin Audio loudspeakers. iK41 can deliver a full 1500 watts per channel into 4O and 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 user friendly front panel interface allows full local control of all features. Dante digital audio network inputs are also provided for digital audio distribution and control. Powerful DSP is fully integrated into the iK41 to provide a multitude of features that ensure maximum performance of select loudspeaker systems. It also provides up to 1000 FIR filter taps @ 48kHz on each output channel, which is essential to implement DISPLAY’s wide bandwidth optimisation process in WPM line array systems. The iK41 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
