Martin Audio IK81-DANTE, 8-ch Power Amp with 4x8 96kHz DSP. 8x 1250w @ 2/4/8Ω

The iK81 can deliver a full 1250 watts per channel into 2, 4, or 8 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 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 iK81 to provide a multitude of features. It also provides up to 1000 FIR filter taps @ 48kHz on each output channel, which is essential to implement DISPLAY’s wide bandwidth optimization process in the WPM line array. The iK81 employs comprehensive protection functions to maintain safe operating conditions of both the amplifier and the loudspeakers driven — including a sophisticated loudspeaker limiter suite that incorporates peak, RMS, and excursion limiting, as well as multiband limiting for passive 2-way systems.
