STEG K4.01

The STEG K4.01 from the renowned K-Competition series is a high-quality 4-channel power amplifier featuring Class A/B technology, designed specifically for demanding car audio applications. With its precise sound reproduction, powerful output stage, and microprocessor-controlled electronics, it provides the ideal foundation for high-quality speaker systems and sophisticated sound installations.

With an output power of 4 × 95 watts RMS at 4 ohms or 4 × 155 watts RMS at 2 ohms, the K4.01 offers ample power reserves for high-performance front and rear systems. In bridge mode, up to 2 × 310 watts RMS at 4 ohms is available.

The integrated multimode crossover enables various filter configurations, such as high-pass, low-pass, band-pass, and full-range. Thanks to dual-filter technology with 12- or 24-dB slope and optionally available AQXM2 crossover modules, the power amplifier can be flexibly tuned to various speaker configurations.

Reliable operation is ensured by the stabilized power supply, the microprocessor-controlled protection system, and the intelligent INTELLISPEED forced cooling system. The STEGLink interface also provides advanced control and configuration options.
