Sescom's specialty cable solves interface problems with Panasonic DSLR cameras when integrating a Zoom H4 or similar audio recorder. The Panasonic Lumix GH2 and Lumix GH1 DSLR cameras utilize an unbalanced stereo mic level audio input on a mini TRS 2.5mm jack. Manufacturers do this to save valuable space in the camera interface. With the age of professional pocket recorders that can produce very high quality sound, such as the the Sony PCMD50 or a Samson Zoom H4N, came devices that output different line level audio signals. To avoid using klunky XLR type attenuators that can produce heavy strain on the cameras mic input connector, these little cables will provide the proper mic levels and preserve the delicate connector contacts inside your expensive camera.
