Noise Canceller Current Acoustic Anti-Jammer Isolator Coupler HM-2

1. HM-2 is a tinnitus eliminator, designed to eliminate 60hz AC signals caused by ground .2. These ground act as radio antennas, breaking and by coupling a 1:1 transformer, thereby the bond of group, so that signal line cannot capture and noise of in first place.3. It is also designed to convert unbalanced wires into balanced wires.4. : Frequency response: 20Hz-20KHz, distortion: 0.005% at 1kHz, crosstalk: equal -97dB, output impedance: 8.7 kHz5.
