[DECtalk] Best way to record sound from a DECtalk Express

[Piotr Machacz]

A very brief explanation is that A line-in input is a more powerful, louder signal, while a microphone is a lot lower and needs to be amplified by the device. So when you use a patch cable (which just has a typical 3.5MM headphone jack type connector on both ends) and hook it up to a sound card or recorder which normally expects microphones to be plugged in, that line signal gets further amplified which is why it distorts.

You may just be able to turn this off. If your recorder has an option in its menus to change the input from microphone to line-in, use it. It might also just be a matter of turning down the recording level far enough, which is how it works on my Zoom H1.

Same goes for computers. Older ones had a separate jack for line-in and microphone. Now the jacks are usually software controlled and can just be changed to what you need. In the case of Realtek for example when you plug something into the mic/line input it opens a dialog asking what you want to use.

Hi,

What is the difference between line-in, and mic-in?
Also, I live in Denmark, so I'm not sure I can buy from those sites. It
doesn't mater for me wether it is sterio or mono. I can always convert it to
mono, if it's sterio.

Make sure you are using a LINE-IN and not a MIC-IN on the recording 
device. The DECTalk output level is far to high for a MIC-IN input and 
the result will be noisy and distorted.

If all you have is a MIC-IN, radio shack makes an "attenuating dubbing 
cord" which will work (but is only mono, doesn't really matter because 
the DECTalk output is really mono - it is wired so that it will work OK 
with a mono or stereo plug) .. I think it is part number 42-2152 .. 
amazon has sellers that carry it.
