SOS, I can not make use of this microphone on my laptop ??? I searched everywhere tutorials, in vain. I want to sign books and tales for visually impaired. Call for "PROS" good advice to a granny very annoyed .My son is far away and I despair of making a purchase that I can not use it. A friend managed to connect once, but for recording ?????? Thank you in advance Dan PS Very good material and more! But is it a mixer?
