[. . . ] Due to their sonic purity and extreme reliability, EV amplifiers have become established in top concert sound and professional installation projects worldwide. PRECISION SERIES COMPACT AMPLIFIERS HI-EFFICIENCY IN A LIGHT & COMPACT FORMAT For more than 10 years, EV's Precision Series Linear Amplifiers including the flagship P3000, have proven themselves with their outstanding audio performance and reliability in many demanding audio applications. In this tradition we are introducing the new Precision Series Compact amplifiers, which offer our proven Precision Series performance and reliability in a new compact, lightweight format. This is made possible by incorporating a highly efficient Class-H design, which results in substantially less heat being generated. [. . . ] This allows the overall size of the amplifier to be reduced substantially without sacrificing performance or reliability. HOW IT WORKS - INNOVATIVE ENGINEERING make the voltage switching totally transparent to the user. This is where EV's amplifier engineering excellence makes the difference over other so-called "Class-H" designs. The audio performance of the Precision Series Compact amplifiers speaks for itself. They truly set the new standard in Class-H amplifiers and meet the expectations we set the original Precision series models. In EV's Class H design, rather than supplying the voltage for the maximum output power permanently, the permanent voltage rail is designed to cover the average music signal. If dynamic peaks require a higher output voltage, the voltage rail is switched to the maximum. This process saves nearly 50% of the power consumption in a conventional design and results in a dramatic reduction in heat output. The real test in a successful Class-H design is to UNIQUE PERFORMANCE · Four models ranging from 2 x 600 W to 2 x 1600 W · Legendary EV's Precision Series sound · 30% Dynamic Headroom · Class H-Design for less heat dissipation · Very light and compact format UNMATCHED RELIABILITY · High precision detent front controls · Dynamic audio limiter · Robust construction & reliable design, made in Germany · Unique protection package including Back-EMF protection A conventional amplifier design has nearly double the power consumption and requires double the power dissipation over EV's Class-H Design of equivalent output power. The Precision Series Compact amplifier runs much cooler even under adverse conditions. The THD of the amplifier is limited to a maximum of 1% for signals up to +21dBu. 40 kHz (±1 dB) 20 k > 300 35 V/µs 107 dB 35 V/µs 107 dB 30 V/µs 105. 5 dB 25 V/µs 103. 5 dB 240 V, 230 V, 220 V, 120 V or 100 V ; 50 . . . 60 Hz (factory configured) 820 W 660 W 500 W 600 W Audio Limiters, High Temperature, DC, HF, Back-EMF, Peak Current Limiters, Inrush Current Limiters, Turn-On delay Front to Rear, 3-stage Fans 483 mm x 88. 1 mm x 368. 8 mm (19" x 3. 5" x 15. 22") 8. 15 kg (17. 96 lbs) 16 kg (35. 2 lbs) 15 kg (33 lbs) 13. 5 kg (30. 8 lbs) Rear-Rack Mount Kit 18" (D) 112933 Americas USA: Canada: Latin America: Telex Communications Inc. 12000 Portland Ave South, Burnsville, MN 55337, USA Phone: 1-800-392-3497, Fax: 1-800-955-6831 Phone: 1-866-505-5551, Fax: 1-866-336-8467 Phone: 1-952-887-5532, Fax: 1-952-736-4212 Europe, Africa & Middle-East Germany: France: UK: EVI Audio GmbH · Hirschberger Ring 45, D 94315, Straubing, Germany · Phone: +49 9421-706 0, Fax: +49 9421-706 265 EVI Audio France S.
