Overview

The K6 fills an important space in modern tour sound amplification, yet it does not use up much room in its single rack space chassis. Absolutely stable with 2Ω loads, it fits subs in smaller systems as well as lows and mids in larger setups. More power is available if needed: Per Step-up card a K6 can be upgraded to become a K8, making it a safe investment – more power without replacing the entire amplifier.

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.

Features

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 a 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 continuous variable speed fan, front to back airflow
  • Temperature forecast with LCD traced historical behavior

General

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

Settings

  • LCD matrix interactive display
  • Comprehensive-user friendly front panel display menu

  • 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
