Description

DELTA8.4-DSP Audio AmplifierThe DELTA8.4-DSP amplifier is a high-performance four-channel power amplifier with a built-in DSP loudspeaker management. The integration of Hoellstern's proprietary DSP controller gives the DELTA8.4-DSP amplifier extra benefits over traditional solutions with separate components. Due to the precise and comprehensive Hoellstern® loudspeaker libraries the DELTA8.4-DSP amplifier offers additional benefits as a loudspeaker brand independent solution with a decisive advantage over conventional system components.With their four individual audio inputs and four individual  audio outputs Hoellstern® amplifiers are perctly suited for all applications. The high sound quality, the extraordinary flexibility and the great overall quality are lasting guarantors for a future-proof investment which will amortise quickly and make the daily routine of professional sound technicians a lot easier. Hoellstern amplifiers are system.

The Hardware

Since its market launch in 01/2004, the Hoellstern® amplifier platform has been a trend-setting pioneer in the professional sound industry. It's not for nothing that competitors have been trying for years to emulate the technical properties of Hoellstern® amplifiers. With our no-compromise design and an equally uncompromising component selection we combine huge output powers with a high efficiency in a compact four-channel construction. Output currents of up to 37 Apeak and voltages of up to 145 Vpeak add to the load independent, strikingly audiophile and neutral sound: a synonym for Hoellstern® amplifiers. Double output power with halved impedance provides stress-free limiter settings and gives the sound technician at the console a feeling of ultimate control over a PA system.  Setting new standards, all Hoellstern® amplifiers have an active power factor correction (PFC) circuit integrated into their super performance switching power supply. Together with the intelligent software-controlled power management (iCVP®- intelligent Constant Voltage Power),this technology allows huge output powers and a safe operation at surprisingly small mains fusings with 16 A (class B circuit breaker). The broad AC mains input voltage range ensures constant high output powers even with AC mains fluctuations and AC mains frequency variations. For a longterm stressless and maintenance-free operation in rough environments, the electronic modules have been sealed against soil and humidity. A dependable cold start temperature of minus 40 °C documents the high quality standard of Hoellstern® amplifiers. In the event of failure, sophisticated protection circuits (LIMIT / LF / HF / TEMP) with intelligent software algorithms will gently limit the hardware without cutting out abruptly. Their high efficiency, relatively moderate heat generation, low heatsink temperatures and outstanding overall quality of workmanship are reflected in high reliability and a long service life.

The DSP Controller

To meet the high demands of Hoellstern® amplifiers, the internal DSP controller is a proprietary development by Hoellstern®. Supported by free programmability of Konfigurator2™ and the extensive manufacturer-independent Hoellstern® loudspeaker library (Konfigurator1™ and Konfigurator2™), the 56-bit DSP controller which is fully integrated into the Hoellstern® amplifiers forms  a comprehensive loudspeaker management system. Its contemporary pioneering role makes the Hoellstern® loudspeaker library a true innovation for the professional PA industry. Four individual audio inputs, an extremely short latency of 0.2 ms (7 cm sound path distance, QuasiAnalog™), a high 56-bit DSP computing power and the Hoellstern® DSPSoftEngine™ architecture allow the successful emulation of all external  controllers and DSP power amplifiers currently available onthe market. With 300 DSP memory locations there will always be enough configuration options on hand. Integrated into the amplifiers, the Hoellstern® DSP controller constitutes a manufacturer-independent system solution which allows to handle very economically the most diverse sound reinforcement applications on the highest level.The DSP controller provides all the required elements: Classic IIR filters and FIR filtering plus combinations thereof.  As a novelty the DSP architecture, the DSP resources and the DSP signal flow which are best suited for the individual application and loudspeaker library, are selected over the Hoellstern® DSPSoftEngine™ per drag and drop for each DSP memory location. The Hoellstern® DSPSoftEngine™ technology greatly increases your flexibility and provides the perfect solution for every possible sound reinforcement task. The eight digital delay blocks always work separately from the selected DSP architecture. Even with extreme audio signals sophisticated TrueRMS limiters and peak limiters guarantee that the loudspeakers are driven in a safe and reliable way. According to the selected DSP architecture the signal limiters function in an anticipatory manner (Hoellstern® ForecastLimiter™) which produces a pleasant listening effect with high levels. Thanks to the internal DSP controller solution and the Hoellstern® loudspeaker library, an integrative system electronics may be used for all loudspeakers and sound reinforcement applications: the Hoellstern® amplifiers.
