PM 6680

  • 4in, 2out，balance & unbalance

  • The PM 6680 is a high-end audio analyzer specifically designed for acoustic testing.


    It features 4-channel analog signal input, with the option to choose between direct line output or connecting to an IEPE constant current source exciter for conditioning microphones, artificial ears, accelerometers, and other IEPE-powered sensors.


    It also offers 2-channel analog signal output, with the flexibility to select direct line output or to connect to an amplifier for output, thereby enabling the driving of artificial mouths, speakers, and other high-power loads.


    This product boasts abundant channel resources and excellent specifications, capable of meeting the mass production acoustic testing needs for consumer products, assisting engineers in creating better products.
