Question in regards to hook up

1032 Views 1 Reply 2 Participants Last post by  brucek
In the cable hook up thread this is stated :

"A microphone input on the soundcard is not suitable (many laptops only have mic-in)."
I am trying to keep cost down and not purchase an external soundcard so help me answer...........

Why is this? please help me understand......thanks

Why is this?
There are several reasons.

SPL meters (such as the Radio Shack meter) output a line-level voltage signal. The microphone input jack offers high gain since actual microphone signals are quite low in relation to a line level signal.

This extra gain at the mic inputs front end usually results in increased noise.

Mic inputs usually enjoy a very limited bandwidth that is designed to comply with a narrow voice frequency range that a cheap microphone would supply. The port often supplies a 5 volts bias signal also.

You require a line-in to use REW.
