Particularly noteworthy is the ability to increase power at lower ohm values, providing ambitious users with flexibility in application.

Welche Funktionen bieten die Multimode-Frequenzweichen des K4.02?

The K4.02 from Steg is equipped with advanced multimode crossovers that can be flexibly configured as high-pass (HP), low-pass (LP), band-pass (BP), and FLAT. The integrated dual-filter technology allows for precise adjustment to acoustic preferences with slope steepness of 12 or 24 dB and variable Q factors of 0.7 or 1. Additionally, 56 AQXM2 frequency modules are available in the range of 22 to 8500 Hz, enabling extraordinary fine-tuning of the sound profile to meet various musical requirements.

Was macht das INTELLISPEED Luftzwang-Kühlsystem des K4.02 besonders?

The INTELLISPEED air pressure cooling system of the K4.02 by Steg dynamically controls the internal temperature of the amplifier. This technology is based on adjusting the air circulation to the power demand, ensuring constant cooling of the system. This reduces the risk of overheating even under high audiophile loads and ensures trouble-free, long-term operation. This feature is particularly advantageous in compact installation conditions, where constant temperatures can significantly affect sound quality.

Wie verhält sich der K4.02 unter verschiedenen Eingangsspannungen?

The input voltage of the K4.02 from Steg is equipped with great flexibility. The input sensitivity ranges from 0.2 to 5 volts, which supports a variety of sources at different output levels. Additionally, the power supply is stabilized up to 11 volts, ensuring a constant power supply and optimized signal transmission. This voltage stabilization minimizes distortions and ensures that the amplifier delivers stable sound performance even during voltage drops in vehicle operation.

Wie funktioniert das Mikroprozessor-gesteuerte Systemmanagement des K4.02?

The K4.02 amplifier from Steg is equipped with a microprocessor-controlled system management that takes over the control and monitoring of internal processes.
