SYMMETRICAL HIFI POWER AMPLIFIER

DESCRIPTION

Characteristic Summary : power amplifier mosfet complementary symmetrical hifi complete with very height output
power and good dynamic, because real delay of the way in level of end exploited for
compensation of frequency to be obtained absolute stability

Output Power : 140 watt at 8 ohm each chanel / 180 watt maximum at 8 ohm
180 watt at 4 ohm each chanel / 250 watt maximum at 4 ohm

Distortion : less than 0,01 % at 140 watt and 8 ohm / at 180 watt and 4 ohm

Input Sensitivity : 1 volt-ef for 130 watt at 8 ohm

Input Impedance : 25 Kilo-ohm

Frequency Characteristic : 4 - 50000 Hz (with source resistance 600 ohm)
