The NIKO 1.7000 from STEG is a state-of-the-art 2-channel amplifier designed for the most demanding SPL challenges. It features a stabilized power supply of up to 10 volts, processed by 24 MOSFETs with 160 A, capable of handling currents of up to 4000 A at the input and loads of up to 0.5 ohms at the output. This amplifier offers extensive protection systems to ensure functional reliability and longevity even under the most intense conditions. Notable are the protection circuits for temperature and short-circuit output, as well as the intelligent fan control "INTELLISPEED". The NIKO 1.7000 combines power with precise control to deliver the best performance in its class.

Protection System of the STEG D Series: 
The NIKO 1,7000 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.
