QUALITY:

DESIGN In compliance with absolute quality criteria, the K competition idea is realized. Total harmony achieved with meticulous care of every detail. Even the smallest part is designed and built to best satisfy its own function.

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

COMPONENTS High quality and precision, MOSFETs selected one by one, solid terminal blocks obtained from the solid 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 placed in the hottest points, the speed of which varies proportionally with temperature.

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

POWER:
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 the S.P.L. The available power, the high current and the impressive dynamics are among the characteristics guaranteed by a design that spared nothing. The massive use of extremely powerful semiconductors, the distribution of power over several transformers in parallel (in the photo, the K2.04 equipped with 4 transformers and 4 inductors) and the use of an extremely effective dissipating system guarantee all the energy and reliability necessary 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 you to add 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 separate and independent LP and HP filters - High-pass, Low-pass, Band-pass, Flat Configurations - Selectable slope 12/24 dB - BY-PASS output - Filter Q 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 heavily degrade the sound. On the cover, an example of a complete Fronte/Retro/Sub multiamplified six-way system, built using exclusively the SMMS functions integrated in the K amplifiers.

CONTROL AND COMMUNICATION: MICROPROCESSOR
K competition amplifiers incorporate an innovative system for managing service operations and monitoring operation. Compared to common analog techniques, every function of monitoring the operating state is performed by a Microprocessor, also responsible for managing new and important functions related to Communication. Continuously analyzing the circuit, the STEG digital system protects the amplifier from malfunctions, controlling the power supply status, ground connection, short circuits and the presence of direct current on the outputs, as well as power-on/power-off bumps and the thermal state of the power devices (by regulating the flow of cold air). If necessary, it intervenes with muting or, in extreme cases, with total shutdown of the amplifier, safeguarding the electronics and connected devices. Each protection event is identified by the LEDs on the control panel and, most importantly, recorded in detail in the integrated memory, as happens with the "black box" of aircraft.

PERSONAL COMPUTER: store data, offers K competition new possibilities of 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 information from its memory that was stored during operation. Thanks to a simple and intuitive graphical interface, MY STEG MANAGER shows on the monitor the status of the amplifier in real time, 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 condition of the amplifier, 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 relating to the last 14 protection interventions. The program, reading the data from the amplifier, faithfully reports temperatures, voltages and type of intervention, showing an analysis of accurate and useful trend curves, both in the overall verification of the audio system and in the search for installation errors.

MY STEG MANAGER provides for the connection of a HUB accessory designed to manage high-level implementations and professional competition systems, through 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 personal information and that of the installer in a protected area of the memory. The entered data will join the digital serial number (entered during production) generating a digital signature that makes each amplifier unique, unforgeable and always recognizable, regardless of tampering or theft.
