About the Powersoft K Series
The Powersoft K Series comprises six 2-channel high-performance power amplifiers positioned as the flagship of Powersoft's pro audio range. Models span the K2, K3, K6, K8, K10 and K20, delivering power ratings from 2 x 2400 W/ch at 4 ohms to 2 x 9000 W/ch at 2 ohms, all within a 1RU chassis weighing 12 kg. A fixed-frequency switchmode output stage underpins sound accuracy and efficiency across the range. Inputs are handled by Combo XLR/6.3 mm Neutrik connectors with link capability, while DSP-equipped variants also carry an AES3 digital input. The 1RU form factor reduces rack space and shipping costs across all configurations.

The Powersoft K Series is a range of six 2-channel high-performance power amplifiers, positioned as the flagship of Powersoft's pro audio technologies. All six models share a 1RU chassis and a fixed-frequency switchmode output stage designed for sound accuracy and efficiency. Despite fitting into a single rack unit, the amplifiers cover power ratings from 2 x 2400 W/ch up to 2 x 9000 W/ch, with a weight of 12 kg across configurations.
Who makes the K Series and where does it sit within Powersoft's range?
Powersoft is an Italian professional audio manufacturer specialising in high-efficiency power amplifiers for live sound and installed audio applications.

The K Series uses Combo XLR/6.3 mm jack Neutrik connectors with link capability as standard inputs across all models.
