Ever need to record an important telephone conversation?

The TP-6 makes phone recording a snap, acting as a multipurpose earphone/telephone pickup. Just plug the TP-6 jack into the "MIC" jack of your recorder, and put the earphone side into your ear. When speaking on the telephone, the TP-6 will capture both sides of the conversation for recording by your voice recorder.

Note 1: The TP-6 is designed for land-line telephones (not cellular or wireless digital phones). Using the TP-6 with cellular phones will create unwanted background noise.

Note 2: When used with the DM-10\DM-20, select Monaural Input in the Menu for selection EXT. INPUT. The TP-6 also includes a 3.5mm adapter, so you can use it on both 2.5mm and 3.5mm microphone jack plugs.
