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 2 Ohm 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.
Fully digitally controlled and with a serial PC communication port as standard, the K6 is also available with KDSP board and KAESOP Ethernet/AES3 interface: the K6 DSP+AESOP amounts 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 ArmoniaPlus (Interface available for MediaMatrix, Crestron, AMX, Q-SYS control and monitoring systems).
Like all K Series models, the K6 is designed for, and absolutely stable with, 2 Ohm loads. Hence, with multiple speakers/drivers in parallel, a single K6 is well capable of powering e.g. a major section of a medium-sized line array, or a number of full-range speakers, effectively reducing the number of amps needed for powering a specific system.
The K6 can be software upgraded to become a K8, and even a K10, making it a safe investment that grows with loudspeaker systems without the need for replacing the amp hardware. This fact reveals the otherwise hidden power density deriving from unique Powersoft technologies despite running off a single mains phase, while fitting into a single 19" rack unit and weighing only 12 kg/26.5 lb, all a result of efficiency exceeding 85%.
Better still, the K6 can be equipped, at the factory or anytime later, with an optional state-of-the-art DSP board for extensive sound 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 Armonia Pro Audio Suite via the standard RS485 communication port.
