STEG QK200.4

The STEG QK200.4 is a powerful 4-channel high-end amplifier from the QK series that impresses with high-quality Class AB technology, precise sound reproduction, and high output power. Thanks to its high-quality MOSFET amplifier technology, it is particularly well-suited for demanding car audio systems where sound quality, dynamics, and power reserves are paramount.

With 4 × 200 watts RMS at 4 ohms and 4 × 300 watts RMS at 2 ohms, the QK200.4 delivers ample power for high-quality speaker systems. In bridge mode, up to 2 × 600 watts RMS at 4 ohms are available, allowing even high-power subwoofers to be driven.

The built-in, flexibly adjustable high-pass and low-pass filters, each with a slope of 12 dB/octave, allow for precise adaptation to different speaker configurations. Thanks to the switchable frequency ranges, the amplifier is suitable for both classic front-and-rear systems and active multi-way systems.
