iKON iK81

Eight-channel 10,000W Class D Power Performance Amplifier

Martin Audio iKON iK81 | High Power, Eight-Channel Class D Amplifier
Where to Buy or Rent

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.

Features

  • Eight channels of efficient Class D amplification
  • Very high power density in 2U rack height
  • 10,000 Watts total power output
  • High performance 96kHz DSP on all inputs and outputs (48kHz on outputs when implementing FIR filters)
  • Switch mode power supply
  • Global mains operation, 85V to 240V auto-sensing
  • Intuitive, user-friendly, front panel interface
  • Analogue, AES3 and Dante™ digital audio network inputs
  • Ethernet network for system control and monitoring via Martin Audio VU-NET™ software application
  • Comprehensive protection and monitoring functions

Applications

  • Dedicated controller amplifier for the WPM, O-Line, XE300, TORUS 8 and FlexPoint systems.
  • Versatile multi-channel amplification for Martin Audio loudspeaker systems

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.

Martin Audio iKON iK81 | High Power, Eight-Channel Class D Amplifier

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 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.
