Will audio drift out of sync with my video camera?
Any two devices (audio & video) that are not being run from a common clock source will be out of "sync" with each other over time. Generally, this won't be apparent with short clips but will occur with longer form projects.
One common solution that seems to come up in forums where this issue arises are a couple of programs by a company called Singular Software: http://www.singularsoftware.com/index.html (DualEyes and PluralEyes)
A couple of articles that cover this subject.http://forums.dpreview.com/forums/thread/3052717http://philipbloom.net/2010/01/23/is/
If absolute lock is required for long periods of time, you can use our HS-P82 recorder resolved to video sync along with the camera.
I hear a noise when plugging my lavalier microphone into the DR-40's XLR jack.
The DR-40's microphone input circuitry is specifically designed for use with truly balanced microphones only."Quasi-balanced" mics or unbalanced mics using adaptors will introduce noise.
You might consider researching balanced lavalier mics by Audio-Technica, Sanken, TRAM, Lectrosonic & SONY (among others).
I hear a clicking noise when recording with one microphone on the DR-40
When recording with only one microphone, set the recording mode to MONO to properly terminate the input.
Why are recordings cut off and a new recording started when they reach 2GB in size?
Because of the FAT format system employed, a single file cannot exceed 2GB. All time computations are based on the maximum file size selected in the REC SETTINGS menu, not the actual SD card capacity.However, that does not mean you cannot use the full capacity of a card larger than 2GB.If the 2GB file limit is reached, a new file is created and then the unit continues the recording.
To see the available capacity based on the actual card size being used, go to the second tab of the INFORMATION page from the MENU options.
What batteries do you recommend for TASCAM handheld recorders?
The longest battery life figures in our tests were obtained using the following batteries:
Panasonic EVOLTA AA
Sanyo eneloop rechargeable AA
How loud is the speaker on TASCAM handheld recorders?
The speaker volume may be considered low.This is because the speaker is only there to confirm that a recording was made. It was not meant to be the main monitor source. That should be done via headphones or you can also output audio to a small powered speaker system.
When recording with a microphone, I hear "helicopter noise," a rhythmic noise in the recording.
The DR-40 is only designed to work with balanced microphones. Do not use an unbalanced microphone with the DR-40.
Which SD or Compact Flash cards do you recommend?
Unfortunately, we do not have the ability to test every company's new media card that gets released. The media cards that we do test can often be found in your product's downloads tab. Over time, these specific cards may become unavailable. At that time, it would be best to contact the CF/SD card manufacturer directly and have them suggest the model with the most similar specifications that is currently available which remains within the maximum capacity limit.
Some manufacturers' U.S. websites are listed below.
