The loudspeaker can withstand contin uous voltages up to 275 volts and allows any combination of voltage to GND (neutral-line-gro und or line-line-gr[...]

CHAPTER 2: POWER REQUIREMENTS 12 ■ Burst Current — The maximum rms current during a period of around one second. The Burst Current is used as a rating for magnetic breakers. It is also used fo r cal- culating the peak voltage dr op in long AC cable runs according to t he following formula: V pk (drop) = I pk x R (cable total) The Burst Current [...]

13 CHAPTER 3: AMPLIFICATION AND AUDIO The Acheron Designer’ s low- and high-frequency drivers are powered by an ex tremely efficient onboar d two-channel, Class-D amplifier that uses minimal AC power when idle. Internal signal processing includes a complex crossover , fre- quency and phase correction, and limiters that prevent driver overexcursio[...]
