on this b11178 real quick, i loaded some testones into nuendo. 60, 300, and 1K, square and sine, and sent them at a low(er) level into the primary, and then the secondary back in, out of a MOTU and back into a MOTU, no loading or anything like that, i'd imagine source Z is real low and load Z is real high. cant find specs on the MOTU anywhere, not real ones with specified Z's.
so anyway, I was getting about 5.3db of step up, and this is with the nuendo meters... all test tones gave about the same measurements. so i probably botched something.... perhaps i need the 26ga, although I figured the gauge shouldnt affect the turns ratio.
anyway, probably my counting ;]
also, is there a better test bed for this, should i terminate either end or anything?
also, i tried out audiotester, from http://www.audiotester.de/, but i had a real hard time calibrating it with my motu 2408... maybe need a 'regular' sound card?
but i just burned some test tones to cd and borrowed a boombox, so i'm going to give it a shot with that and the scope to see what the deal is.... should work until i get a function gen somewhere.
