iKon iK81 8 Channel Class D Amplifier 8x1250W @4Ω 2U

The iKON iK81 is an advanced 8-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 the Martin Audio Wavefront Precision WPM line array, the iK81 can also provide multi-channel amplification across the Martin Audio loudspeaker range.

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.

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 optimisation 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 which incorporates peak, RMS and excursion limiting, as well as multiband limiting for passive 2-way systems.

Due to the global shortage in ‘Brooklyn II’ Dante network cards, IKON amplifiers and the DX4.0 controller will no longer as standard have these network cards integrated, therefore this item does NOT include DANTE, please contact our sales team on 01525 850085 for more info on the DANTE version.
