Audio - Main page. Amplifier kits in Sound & Vision. Marchand Electronics PM2 and PM22 Power Amplifier Modules. 75 Watt RMS into 8 Ohm. Complementary Darlington output stage. Integrated Circuit driver circuit. Over-current and over-temperature protection. Class A or class B operation. These conservatively rated power amplifier modules will deliver a clean, low distortion 50 Watt of power to any 8 Ohm loudspeaker.The amplifiers are rated to drive reactive loads with a phase angle of up to 45 degree at full output voltage.The amplifiers make use of an integrated circuit driver chip and two complimentary darlington power transistors that are mounted directly on the heavy-duty heat sink for the output transistors. Specifications:Frequency response: 5Hz-50KHz +/- 1dBTHD at 1KHz: better than 0.01%; Voltage gain: 20 dB (10x), non inverting;Input impedance: PM2: 100 KOhm, AC coupled.
