The K1.2500 is a 1-channel amplifier from STEG, characterized by intelligent functions and high technology. This amplifier incorporates numerous protection systems that guarantee safe performance. These include checking for output short circuits, monitoring the direct current on the speaker wires, and overseeing temperature rise and supply voltage. Also significant is the Intelligent Fan Control "INTELLISPEED". The system reacts immediately to any malfunction and allows for immediate reporting of any issues through special software. Thus, the K1.2500 is a model that impresses with advanced technology and the highest safety.

Protection System of the STEG K Class-D Series:
"It integrates various protection systems to control the following functions:"

• short-circuit output
• Direct current at the ends of the speakers
• Increase temperature
• Temporarily mute in the ignition
• Supply voltage outside the permissible range
• Intelligent "INTELLISPEED" fan control
• Asymmetrical power supply between the two connections

The numerous "sensors" of the circuit send a continuous stream of data that is processed at very high speed. The protection system reacts immediately, intervenes accordingly, and reports any malfunctions via the LEDs on the control panel. The other protection system is managed by the modulator, which monitors the circuit in the output stage.
