Re: [RTTY] Sound Card Comparison (Soundmax On MoBo, Turtle Beach Santa Cruz, and M-Audio Revolution)

[Jerry Pixton <jpixton@shentel.net>]

Bob,

Thanks for pictures. I had been sitting here this morning wondering - if 
both the Audigy LS and the Turtle Beach have the same limitations ie no 
mute on mike why not go work 24 bits? But Bob points out I have to compare 
the 16 bit modes on both card.

Now if I can figure out how to switch my microphone to two radios with out 
using the Sound card, I could get two Turtle Beachs. Maybe that is what I 
can use the on-board Soundmax for????

Time to experiment
