The K2 DSP+AESOP can be software upgraded to become a K3 DSP+AESOP, making it a safe investment that grows with loudspeaker systems without the need for replacing the amp hardware. With much more behind the front panel than meets the eye, the unit still takes only a single space in a 19” rack and weighs only 8 kg/17.7 lb, all a result of efficiency exceeding 85%. A fully integrated state-of-the-art DSP yields extensive system management functionality. IIR/FIR filters, safety features like TruePower™ limiting and LiveImpedance™, as well as the convenient Active DampingControl™ are intuitively manageable with the free PC software Armonía Pro Audio Suite™. The AESOP interface provides four standard Ethernet ports, plus adding hub functionality for two AES3 digital audio streams equivalent to 4 analog signal channels over the same RJ45, allowing for a redundant ring architecture too.

  • Green Audio Power®: more amplifier output power from the AC mains power distribution due to >85% efficiency
  • Outstanding performance and operational safety
  • Excellent sonic quality by design, including amp clip limiters and patented ripple cancellation network
  • Proven reliability, yet downloadable log file of all functional fault events with time-related trace
  • Numerous amp/system/venue parameters can be configured, locked, and monitored; i.e. AC mains voltage/current draw to protect from breaker tripping
  • Top-grade DSP with high dynamic range and extensive feature set
  • Separate input/output EQ’s with numerous filters of various types up to 48 dB/oct (IIR), linear phase (FIR), and hybrid (FIR+IIR)
  • Sophisticated limiter system comprising peak, RMS voltage, RMS current, and TruePower™ limiting
  • Speaker wire compensation with Active DampingControl™
  • LiveImpedance™ load monitoring with regular musical signal
  • Plug & play communication and redundancy for control and digital audio:
  • Fully digitally controlled amplifier providing feedback of all status information
  • 4-port AESOP Ethernet/AES3 interface allowing daisy-chaining and redundant ring architecture
  • Fully manageable via Armonía Pro Audio Suite™ software, intuitive system setup and maintenance, control and monitoring
  • AES3 digital audio distribution over Cat-5e cable: two streams equaling four analog channels, low latency, glitchless fallback to analog backup signal
  • Mono-bridgeable amplifier channels; switch for linking analog signal inputs
  • AC inrush current limiting; channel output voltage limiting
  • Digital gain attenuator for gain/sensitivity selection
  • Front panel interactive LCD display for local access and configuration
  • Front panel SmartCard reader/writer for firmware updates and preset storage
