I wanted to ask a quick suggestion about an audio transformer such as
<http://www.murata-ps.com/data/magnetics/kmp_da100.pdf>

(I find it hard finding them, generally speaking)
to be used on both the home automation audio system (simple decoupling
from a PC audioboard to TPA0172 TI I2C-controlled audio amplifier, high
impedance, nothing special)
and the FMI device (1-4KHz circa @600ohm, as described some time ago).

They should work fine enough; I am just wondering how the 3 different
kind of impedance will impact my requirement... also considering that
only the 1.00 - 1.59mH seems to be available...)

thank you !
