A85F & A95UF - maximum signal levels?

FAQ #1993 Updated October 14, 2008

Question:

Do the A85F & A95(U)F convert a 1/4", unbalanced signal into a XLR, balanced signal so that the noise cancellation of an XLR line is utilized or do they simply take the two lines of a 1/4" & use only two pins of a XLR acting as an adaptor? I need to find something (that's not in the thousands of dollars range) that can convert unbalanced to balanced & back again so that i don't get massive amounts of cross talk and ground noise from my (unfortunate) long run of numerouse cables. Would either of these work?

Answer:

The A85F and the A95UF do contain transformers that convert an unbalanced, high impedance signal to a balanced, low impedance signal (and vice versa). But either device is designed to only handle microphone level signals [less than 0.1 volts (-20dBV)].

If you need to balance line level signals (great than 0.1 volts), consider the use of the Shure A15BT or contact: http://www.jensen-transformers.com/
