A four-channel 20,000 W Class D power amplifier in a 2U rackmount chassis, representing Martin Audio's highest-output iKON amplifier platform for driving large-format passive loudspeaker systems. Delivering 5,000 W per channel into 2 Ω and 10,000 W bridged per channel pair, it combines extraordinary power density with 96 kHz DSP on every input and output, making it the natural pairing for SXH218 subwoofers and Wavefront Precision arrays in large-scale touring and fixed installations.

Each output channel provides up to 1,000 FIR filter taps at 48 kHz and a full loudspeaker limiter suite — peak, RMS, excursion, and multiband limiting. Inputs span analogue XLR, AES3 digital, and Dante (AES67-compatible) via RJ45, with four Neutrik Speakon NL4 outputs. VU-NET Ethernet control and monitoring enables real-time supervision across entire multi-amplifier systems. Audio performance is identical to the iK41: 7 Hz to 30 kHz frequency response, THD below 0.05%, and dynamic range exceeding 113 dBA.

• 4 channels; 5,000 W per channel into 2 Ω; 3,000 W per channel into 4 Ω
• Bridged output: 10,000 W per channel pair @ 4 Ω; total system power 20,000 W
• Inputs: 4 × analogue XLR, AES3 digital XLR, 4-channel Dante (RJ45, AES67)
• Outputs: 4 × Neutrik Speakon NL4; frequency response 7 Hz – 30 kHz; THD <0.05%
• VU-NET Ethernet control & monitoring; 2U rackmount; dimensions 482 × 88 × 441 mm; weight 12.5 kg

The go-to drive amplifier for large-format Martin Audio systems in major touring productions, festival main stages, large houses of worship, performing arts centres, broadcast facilities, and high-demand corporate AV installations.
