The Mic-Line Pro allows you to connect a line-level audio source with 1/4 inch connector to the iPhone/iPad/iPod or other compatible device for quality recording. This adapter is NOT for recording from microphones. Use this adapter to record from headphone jacks, audio output jacks or from mixers and soundboards that have line-level outputs. The headset connections only have a mono mic input so, although you can connect a stereo signal, it will only record in mono. This adapter incorporates a built-in attenuator which reduces the line level signal down to a mic-level signal suitable for input for recording. This adapter works with mono or stereo 1/4 inch output Jacks.

How it Works: Plug the adapter into the iPhone (or other device) headset jack and then the plug the 1/4" plug into a line-level output on your equipment . The iPhone will recognize that an external mic is connected and turn its internal mic off allowing you to record using the external audio source. This adapter works with all audio/video recording apps and other functions just as the internal mic would.


Question: Will this adapter work with a stereo audio source?

Answer: The combined headset jack on the iPhone and other devices only has a mono mic input so you cannot record in stereo. Most recording apps split the mono signal into both left/right channels when recording so the audio will play back in both ears. There is a new stereo microphone product available which will allow for stereo recording using the docking connector; this is currently the only option available for stereo recording, Tascam IM2 stereo mic.

Q: Why do I need a different adapter for a microphone?

A: The iPhone headset mic input is a mic-level input. The mic-level signal is much lower than a line-level signal which is used in audio outputs. This adapter has a built-in attenuator which reduces line-level signals down to mic-level signal strength. If you connect a mic to this adapter the signal would be reduced to a point that you would not be able to hear it in a recording. Use the MIC versions of this adapter for recording from microphones.

Q: Can I connect a cable with a different style connector if I use an adapter?

A: Yes, you can use an adapter to convert from a 1/4 inch output or XLR, ect.
