[. . . ] But many are not aware that Electro-Voice® also has more than 50 years of expertise in the design and manufacture of high performance professional power amplifiers. EV's unwavering commitment to become the PRECISION SERIES COMPACT AMPLIFIERS HI-EFFICIENCY IN A LIGHT & COMPACT FORMAT EV's Precision SeriesTM Linear Amplifiers - including the legendary flagship P3000 - established EV amplifiers' reputation for outstanding audio performance and reliability in demanding audio applications throughout the 1990s. [. . . ] The Precision SeriesTM Compact Amplifier line now offers the same performance and reliability level in a new compact, lightweight format. This is made possible by incorporating a highly efficient Class-H design, which results in substantially less heat generation. This allows a substantial reduction in the overall size of the amplifier without sacrificing performance or reliability. HOW IT WORKS - INNOVATIVE ENGINEERING Class-H design is the ability to 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. Ultimately, EV Precision SeriesTM Compact Amplifiers set the new standard in Class-H design, whilst meeting the high expectations EV set for the original Precision SeriesTM models. Take a listen: The audio performance speaks for itself. Rather than supplying the voltage for the maximum output power permanently, in EV's Class H design 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.
