The small DC power jack by the XL1 mic jack is 5 volts with a rather limited current capacity. Not suitable for phantom powering a mic, it is intended to power the Canon mics. Also the ground return for the DC from the jack is through the mic ground. Intended that way to prevent short circuits if someone stick in a pin, small nail, etc..

So the small power jack is for output correct, 5Volts. So can I plug a standard mono mini plug with a mono mike attached into the cannon jack and not worry about the small power jack?

Thanks,

Dan O'Bannon

Yes. It will work as long as the mic is self-powered (i.e., does not require pahntom power of bias from the recorder).

Be aware tha plugging in a mono mic will result in sound on the left channel and a silent right channel. However, if the mic connector is a stereo mini-phone plug with balanced output (as from some wireless mic receivers), the sound will be on left and right channels, and the channels will be 180 out of phase.

Thanks Don.

Could you briefly explain what 180 out of phase means, dosen't sound like a good thing.

Thanks again, Dan O'Bannon

Means that the sound in the left channel is equal in magnitude but opposite in sign to the sound in the right channel.

If added together (as when recording to the mono (linear) track on a VHS tape, you end up with with a net result of no or very low level sound on the mono track. If played through a stero system, the audio may not have a properly centered, stable stereo image.

Thanks Don, would it be considered "stereo" if I used a mono shotgun mike for the right channel and a seperate mono shotgun mike for the left channel using the ma100?

I do like the feal of the canon onboard stero mike but it just dosen't give a clean sound.

Thanks for your time, Dan O'Bannon

Depnds on how the mics are positioned relative to the sound field you are recording, and the 'stereo' effect you are trying to achieve.

FWIW: I use a pair of wireless mics through a MA-100 to record band performances in stereo.

There are a numbr of options for stereo recording with a pair of mono mics. The Shure website has some information on this. Note that shotgun mics provide a very narrow acceptance pattern, so they may not be a good choice for many situations.

Thanks Don you've been very helpful.

One more thing if you don't mind, what would be a good mike choice for recording bands live, say in a coffee shop situation? Or maybe you could direct me to a website that gives mike choices for different situations. I will check the shure website.

Thanks, Dan O'Bannon

Best mic depends on details of the setup, the band, number of performers, instruments, and how much control you the over mic placement, if you have a mixer, ertc.

If they are using a sound board, best sound maybe to get a feed from the sound board. At least yo get best sound interms of the mixer operators taste.

If you can only use one mic on a stand, consider a single point stereo mic such as the AT-825 or AT-822. Ther are other single popoint stereo mics at similar price points as well ans higher and lower prices.

If a very loud band, consider using something like the SM58 or Beta58A. They are rugged, not prone to overload from high sound levels, and the cardoid pattern will provide rejection to the rear to tone down audience noise..
