What? You've been having audio problems with your Sanyo Xacti HD 1000, 1010, and 2000? Well so was I. I contacted Sanyo's customer support line. The woman on the line was what some would refer to as a "bitch". She had probably been there two days, and didn't know what the heck I was talking about. She was no help, and was pissed that I had the Sanyo HD200o which is not available in the US at this time. She claimed that the HD 1010 and the HD 2000 were so different that audio problems with one would not work for the other. Well, she was wrong. Without help from Sanyo, I figured it out myself. So, to Sanyo's US support crew, "Bite my butt."
Here is what my audio sounded like with a Mono Mic through the 3.5mm-2.5mm stereo adapter:
Wow, that sounds horrible doesn't it. So, what is the problem? Most consumer cameras with a mic input have 3.5mm (mini plug) input. Well, the Sanyo Xacti has a 2.5mm input.
The adapter that comes with is only stereo. The Sanyo seems to use joint stereo encoding, thus giving you a distorted garbled sound. So, what is the solution?
This little jewel from Radio Shack allowed my mono Mics to work, and stopped me from sending this great HD camcorder back.
I bet tons of folks have had this problem when using a mon0 mic. I was using an Azden WMS-Pro Wireless mic. I used it wireless as well as just plugging it into the camera. It sounded fine after I converted the sound to mono while editing. Hope this helps.
