MA-100 XLR audio adapter questions

Carl Walters · February 9th, 2005, 01:40 PM

Help,

I have recently purchased the MA 100 xlr adapter from ebay, but unfortunately it does not have the bracket for adding the battery or radio mic. Does anyone know where I could obtain one, or does anyone have any photos of one so I can make one myself.
Also do you know the part number.
Thanks in anticipation.

I could be wrong, but isn't it only the MA200 that has that dual charger?

Carl Walters · February 9th, 2005, 02:03 PM

Yes the 200 does have the dual charger but the 100 does have an bracket fitting. There are some screw holes built in. When I purchased it the description included "sorry but i don't have the bracket" or words to that effect.

Ow okay, sorry.

Good luck! Maybe you could keep searching on ebay or do a request on the Private Classifieds boards here, maybe someone of the forum here has one for you.

Carl Walters · February 10th, 2005, 07:52 AM

Mathieu,
no problem, thanks anyway, as they say you learn somethiong new everyday.

++maybe someone of the forum here has one for you.++

That would be nice.

Try Canon's national parts to order one.

You can see the MA-100 bracket in the second photo (MA-100 mentioned in the caption) at: http://www.dvinfo.net/canon/articles/article80.php

(Note: the velcor is not part of the standard MA-100.)

Carl Walters · February 11th, 2005, 11:02 AM

Thanks for that, I'll get in touch with them if I don't get any offers on the classified forum.

Can I use the BEC AT100 Mounting Box for Mounting Audio Technica U100 - Wireless Receiver on the ma-100? Will it bolt on to the existing holes on the bracket? I don't want to use velcro.
If it does work, where can I purchase it? B & H has been out of stock of this item for a very long time.
Thanks in advance for your help.

Rene Rodriguez · March 8th, 2005, 10:12 PM

I want to use this on my ma-100.

I tapped into the church sound system a few weeks past using a mini adapter to Audio 1 with a Y splitter to L-R. (audio was set to Mic). I got a constant harmonic about 60% up on the audio indicator............a few weeks before that, I used another facilities sound system and had no problem with audio using the same rig and settings. Anyway, I just got the MA-100 yesterday and was wondering if I can connect to fixed sound systems using XLR connections from sound systems or am I limited to using microphones only? Or should I set Audio 1 to "Line" when tapping into a fixed sound system? OR, should I get the BenchTek DXA-6 to use with both mic's and fixed sound systems? Help would be greatly appreciated.

Lynn Earl McDow · October 28th, 2005, 07:49 PM

I am a newbe , so I so not know is this will help or not . I run the sound system for a church and we do some video taping. I have not had the problem you had. I use balanced XLR cables coming out of the mixer into a 31 band EQ. Then XLR cables form the EQ to a bench tek. The Beach Tek is sec at line. With headphones on the DV Camcorder, I wuse th EQ to sut out AC- heater sound, hiss, and other sounds.

Don Palomaki · October 29th, 2005, 06:00 AM

The MA-100/200 is designed for mic level inputs. If you feed it a line level signal, it will be overloaded, and it will clip and distort. Also, it is a transformerless design, so it does not provide the same level of isolation from the source found with transformer-based designs.

If all you have is line level source, then use a 30 dB pad (an attenuator) availabel from most places that sell profesional sound gear.

Many mixers have tape output jacks that provide a nominal -10 dB output level via RCA jacks. You should be able to connect them directly to the XL1 Audio 1 or Audio 2 inputs.

The noise issue you describe sounds like a possible ground loop. More likely if you are using the A/C power adapter with the XL1, but still possible if using battery depending on the circumstances and connections you have at the venu.

An item that might help is to use an "Audio system ground loop isolator," available from Radio Shack."

Rich Herrin · October 29th, 2005, 03:57 PM

I appreciate both replies. I'm going back to the church tomorrow for the sole purpose of doing a test and try and isolate the problem. Every tid-bit of info helps a video / audio novice learn. Thanks again.

Rich Herrin · November 2nd, 2005, 07:15 PM

Maybe someone can clarify why the MA-100 has a DC connection! I can't find any info on Canon's site, there's nothing in the spec's or the flimsy little instruction sheet that comes with the unit. Wondering is driving me nuts. The only value I can figure, is that it possibly adds a little ump to the microphone to compensate for line loss. HELP and THANKs
