iPhone 4 with Shure SM58 External Microphone

Visit the articles section on Life is a Prayer.com for more information - In this video, I demonstrate using the iPhone 4 with an external Shure SM58 dynamic microphone, through my iMac (using a Griffin iMic to get the mic into the computer). I'm using a KVConnection adapter to get the line-level output of the iMac down to a usable input on the iPhone.

why the background noise? the mac itself?

@krzemianpl - I think I had to turn up the level on this recording due to the fact that I was speaking more quietly than usual.

Good sound... Are you familiar with the DigiDesign Mbox? That's what I have my mics plugged into.. Could I plug the headphone jack on that into my iPhone to record better quality audio when I'm shooting video at home? Do you know how I would do this? Basically, how do you run an audio line in into the iPhone for video recording?

[geerlingguy]

@setYourselfFreelance - I've used an mbox before - basically, you need a different adapter (for line-level audio) from KV Connection - find more information on my lifeisaprayer-dot-com articles, under audio/video stuff.

@geerlingguy Why couldn't I just plug the headphone out on the Mbox into the line in on the iPhone? As long as the level wasn't too high.....

[geerlingguy]

@elliottsongs - Unfortunately, there are two problems:

1. There is an impedance mismatch between the line-level (or headphone-level) output on your Mbox and the iPhone.

2. The pins on the TRRS connector on the iPhone are not the same as the pins for a simple headphone-to-headphone (TRS) cable.

The easiest solution is to simply buy the KVConnection cable.

Thank you for all theses great videos, they're really helpful. I have a Samson hand held mic and I'm using the KV connection that also lets you plug in headphones, but I can't get rid of the hiss. How are you able to do this?

@archstlmedia Thanks...looks like a pretty cool little app.. Too bad it doesn't do video, but I guess I could use it to get the input signal right before shooting video in the native app

@setYourselfFreelance - You can do this in the FiRe app, but not in any other iPhone app I'm aware of. You're limited to making level adjustments before the iPhone, for the most part.

@geerlingguy Got it...thanks! Then, one other question...how do you get the level right going into the iPhone? Is there a way to set the input sensitivity on the iPhone?
