PM 6181

8in, 2out shuttle
PM 6181 is an audio analyzer designed specifically for sound and vibration testing.
8-channel analog signal input with optional IEPE constant current source exciter enabled or disabled for conditioning IEPE-powered sensors such as microphones, accelerometers, etc. 2-channels of analog signal output, which can be directly routed out or connected to the amplifier base plate and output, and then realize the high-power load drive such as artificial mouth and speaker.
The product has rich channel resources and excellent indicators, which can meet the acoustic test of the consumer electronics industry, the automobile industry, and the white goods industry.
