What is the difference between the powered and the non powered microphone units?
The two styles of mics are used in different ways. Generally speaking, the battery box is generally for both the LINE IN and MIC IN and all of the non powered mics are for the MIC IN inputs of your recorder. All of the non powered Stereo and Mono mic units are designed to be plugged into a recorders MIC IN jack because they use the voltage from your recorder in order to operate. Most manufactures call this the “powered input.” Our non battery mics work with recording equipment that gives 1.5 to 10 volts to the mic input. However, the less voltage supplied by the recorder, the less dynamic range you will get. This rule includes most other “stealthy” type mics offered on the net. Check your owner’s manual for your recorder’s specifications. The Powered Battery Box Stereo mic units enable one to use the LINE IN input instead of MIC IN because it supplies 9 volts to the mic elements. Using a battery box is recommended by experienced live music tapers for the clarity gained in loud situatio
