2x 2800W@2Ω, 2x 2600W@4Ω, 2x 1400W@8Ω, 8kg AES3/RS485 serial port
 

The most versatile model due to an attractive mix of features, size and output power, making the K3 an outstanding value. It is built on same technologies as every other K Series model, and indeed, the K3 produces the same great sound quality, no matter what type of loudspeaker it is connected to.

In use worldwide by leading touring and event sound companies, K Series is preferred among the top ranking system designers, sound engineers, and system techs on the road for making their lives easier, giving them reliable premier-grade power and headroom in the smallest possible package size.

Fully digitally controlled and with a serial PC communication port as standard, the K3 is also available with KDSP board and KAESOP Ethernet/AES3 interface: the K3 DSP+AESOPamounts to a fully integrated, highly sophisticated yet easy to use power source including state-of-the-art sound shaping and system management capabilities, remotely controllable via Powersoft's Armonía Pro Audio Suite™ (Interface available for MediaMatrix, Crestron, AMX, Q-SYS control and monitoring systems).

Power supply

  • Advanced switch-mode worldwide operating power supply technology for high performance and compact size
  • Power Factor Correction PFC for extremely low mains consumption and extremely wide mains operating range
  • Low Inrush Limiting reduces AC inrush current, removing the need for expensive power sequencers

Protections
Fully protected circuit design with:

  • Ac protection: shut down power supply when AC mains voltage is outside operating range
  • Clip limiter: prevents severely clipped waveforms from reaching loudspeakers, while still maintaining full peak power output
  • DC protection: protects against infrasonic signal at the outputs
  • VHF protections: protects the loudspeakers against non audible, strong, non musical high frequency signals
  • Short circuit protection: protects the amplifier from short circuit or other stressful events for the output circuits with automatic protection reset
  • Long term limiter: protects the loudspeaker against steady long term rms (non audio) signals reducing maximum output
  • Thermal protection: output stages operating temperature up to 80 °C (176 °F)
  • Temperature controlled continous variable speed fan, front to back airflow
  • Temperature forecast with LCD traced historical behaviour

General

  • Fixed frequency switchmode output stage for high grade sound accuracy
  • Compact size - all models only 1 RU for reduced rack cost and space
  • Light weight - for easier racking and shipping: 8 - 12 kg (17.6 - 26.5 lbs) according to configuration
  • Combo XLR/6.3mm jack Neutrik input connectors with link capability
  • AES3 digital input*

Settings

  • LCD matrix interactive display
  • Comprehensive-user friendly front panel display menu
  • Built-in defeatable clip limiters for each channel
  • Digital gain-attenuator control
  • Defeatable gate selection for each channel
  • User selectable gain/sensitivity
  • User selectable maximum output power for each channel
  • User selectable maximum mains current draw
  • Lockable set-up by user selectable access key code
  • Built in remote control via the RS-485 interface provides full diagnostic, operational setting and system monitoring

Monitoring

  • Hardware monitor available for fast local diagnostic
  • Load impedance measurement / display for each channel
  • Output power measurements / display for each channel
  • Mains voltage and current measurements / display
  • Downloadable log file of functional fault events with time related trace
  • Smart Card settings, parameters and upgrades functionality

Digital Signal Processing*

  • Analog Devices SHARC® DSP architecture
  • AD/DA converter: dual 24bit @ 96 kHz Tandem® architecture, 127 dB dynamic range, per channel
  • Input/output independent equalizers per channel providing PEQ, raised cosine, shelving IIR filters as well as custom output FIR filters
  • Delay up to 1 s for time alignment
  • Active DampingControl™ for cable compensation
  • Power limiter (TruePower™, RMS voltage, RMS current) + Peak Limiter
