Delta 8.4-DSP - Amplificatore 4x4 DSP - 4 x 1300 W @ 8 ohm

HIGH Performance Digital Amplifier -  
Hoellstern-Delta 8.4_lowHoellstern-delta-rear low    The HardwareSince 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 two-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 10 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. 
DELTA 8.4 Audio AmplifierThe DELTA 8.4 amplifier is a high-performance two-channel power amplifier.    With their two individual audio inputs and two 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.
