Powersoft Digam K10 2-Channel High Performance Power Amplifier

About Powersoft K10
The K10 is nothing short of power with 12,000 W from a single rack space chassis. Capable of driving subwoofers and large-scale FOH systems equally well, numerous touring sound reinforcement systems are built around racks exclusively utilizing K10’s for all frequency bands, benefitting greatly from maximum flexibility. Operation with 2 Ohm loads is not only safely possible but recommended, reducing the number of amplifiers required in a system.

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 K10 is also available with KDSP board and KAESOP Ethernet/AES3 interface: the K10 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).

For medium to large sound systems, the K10 is the most versatile amplifier within the K Series. Equally useful for most subwoofers as well as high-power fullrange systems, it is ideal as the one amplifier model powering entire systems, resulting in uniform, identical, and ultra-compact amp racks serving any configuration and purpose.

Due to remarkably high efficiency exceeding 85%, the vast power density paired with unique Powersoft technologies warrants top performance despite running off a single mains phase, while occupying only a single 19″ rack unit and weighing a mere 12 kg/26.5 lb. Like all K Series models, the K10 is designed for, and absolutely stable with, 2 Ohm loads, further reducing the number of amps required to power a specific system.

Better still, the K10 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.

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 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 Degree C (176 Degree F)
• Temperature controlled continuous variable speed fan, front to back airflow
• Temperature forecast with LCD traced historical behaviour
