QUALITY:

DESIGN In compliance with absolute quality criteria, the K competition idea is realized. Total harmonic balance achieved with meticulous care of every detail. Even the smallest part is conceived and built to best fulfill its function.

PREMIUM MATERIALS Structure and end fairings made entirely of aluminum, finely worked and treated. The printed circuit is constructed with materials that meet military standards and professional standards, reinforced with gold-plated copper bars to handle the very high currents involved.

COMPONENTS High quality and precision, MOSFETs selected one by one, solid terminal blocks machined from solid material that accept large cables and passive components with very low tolerance.

DESIGN Forms designed by function, elegant and sophisticated lines. Designed to dissipate heat quickly, they integrate INTELLISPEED fans located in the hottest spots, whose speed varies proportionally to temperature.

SOUND Output stage and preamplifier as a synthesis of STEG know-how. Exclusive circuitry such as G.R.I.P.S. (which eliminates any external interference), Straight-In (reduced signal path) and the new audiophile drivers entirely with discrete components, the heart of the Beautiful Sound K competition.

ENERGY:
K competition, the name of these new electronics. represents the commitment made by STEG in creating amplifiers designed, in addition to sound, for competitions and for S.P.L. The power available, the high current and the impressive dynamics are among the characteristics guaranteed by a project that spared nothing. The massive use of extremely powerful semiconductors, the distribution of power across various transformers in parallel (in the photo, the K2.04 equipped with 4 transformers and 4 inductors) and the use of an extremely effective heat dissipation system guarantee all the energy and reliability needed to continuously drive any type of load, down to 1 ohm.
SERIALPOWER is an exclusive series connection mode of the outputs, reserved for stereophonic models, allows summing the power of two units as if they were a single amplifier.

FUNCTIONALITY:

The numerous functions present on the input panel constitute the SMMS system (STEG MULTIWAY MODULAR SYSTEM). Dual LP and HP filters separated and independent - High-pass, Low-pass, Band-pass, Flat configurations - Selectable slope 12/24 dB - BY-PASS output - Q of the filter 0.7/1.2 - Dual frequency adjustment technology with 4-step Switch or AQXM2 Modules. SMMS allows the creation of sophisticated multiway systems (3,4,5,6 ways and more, according to installation needs), avoiding the use of expensive and noisy external cross-overs that seriously degrade the sound. On the cover, an example of a complete Front/Rear/Sub multiamplified six-way system, built using exclusively the SMMS functions integrated in the K amplifiers.

CONTROL AND COMMUNICATION:
K competition amplifiers incorporate an innovative system for managing service operations and monitoring operating status. Compared to common analog techniques, every supervision function of the operational state is performed by a Microprocessor, also entrusted with managing new and important functions related to Communication. By continuously analyzing the circuitry, the STEG digital system protects the amplifier from malfunctions, monitoring the power supply condition, the ground connection, short circuits and the presence of direct current on the outputs, as well as power-on/power-off transients and the thermal condition of the power devices (regulating the flow of cold air). If necessary, it intervenes with muting (Muting) or, in extreme cases, with complete amplifier shutdown, safeguarding the electronics and connected devices. Every protection event is identified by the LEDs in the control panel and, above all, recorded in detail in the integrated memory, as happens with the "black box" of airplanes.

PERSONAL COMPUTER: to store data, offers K competition new possibilities for use. STEG has created a Hardware/Software kit that, through the STEGLINK connection, allows communication between the amplifiers and the Personal Computer.


MY STEG MANAGER is the program that interacts with the integrated microprocessor, drawing from its memory the information stored during operation. Thanks to a simple and intuitive graphical interface, MY STEG MANAGER displays the amplifier status in real time on the monitor, reporting fundamental operating parameters such as: power supply and remote voltage, operating temperatures (right and left side of the heatsink), fan activity and, above all, detailed condition of the protections. The user, analyzing the information, is able to quickly determine the cause of any anomalies.

In addition to the instantaneous amplifier condition, MY STEG MANAGER can display the history of protection events. From one of the menus, you access a section that collects operational details and that graphically summarizes the data related to the last 14 protection interventions. The program, reading data from the amplifier, faithfully reports temperatures, voltages and type of intervention, showing an analysis of the trend curves that is accurate and useful, both in the overall verification of the audio system and in the search for installation errors.

MY STEG MANAGER provides for the connection of an HUB accessory designed to manage high-level implementations and professional competition systems, thanks to which it is possible to connect up to 10 K competition amplifiers to the PC. Read yes, but also write. The software in fact also allows you to record your details and those of the installer in a protected area of the memory. The data entered will be combined with the digital serial number (entered during production) generating a digital signature that makes each amplifier unique, uncounterfeit and always recognizable, regardless of tampering or theft.
