Q: Will this adapter work with a stereo mic ?
A:Q: Why is an external phantom power supply required for condenser mics that do not have batteries?
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
All condenser microphones require power to operate. Some condenser mics supply that power from batteries and some require phantom power from the device they are plugged into. Since the iPhone cannot supply the required phantom power, a portable phantom power supply must be used for these types of microphones.Q: Can I connect a microphone with a different style connector if I use an adapter?
Yes, You can use adapters to connect microphones with 3.5mm or 1/4 inch connectors.
