The LN2MIC-ZOOMH4N from Sescom is a problem solving cable for users of HDSLRs who are using a Zoom H4N or Zoom H1 as a secondary audio recording source. Many professional DSLR cameras have unbalanced stereo microphone level audio inputs on a mini TRS 3.5mm jack. The Samson Zoom H4N or H1 output line level audio signals. This cable provides the proper microphone levels and preserves the delicate connector contacts inside the camera, allowing users to go directly from the audio recorder into the camera.
The cable features a -25dB L Pad attenuator on both audio channels to reduce the prosumer line level output (-10dBV) to the cameras microphone input level. The cable is designed with the proper impedances to assure maximum voltage transfer and low noise operation. The cable shield is isolated on the camera end to prevent shield noise from directly coupling into the camera connector ground. All resistors values are 1% metal film to assure similar voltage attenuation between the stereo inputs and cable ends are labeled for proper connection.
