signal to the Hi-Z input of a sound card.
It's important to remember: a high-impedance
signal can be passively split if you connect only
high-impedance inputs.
You can split a low-impedance signal, such as the
output from a preamp, e.g. the Lehle Sunday
Driver or the output from a sound card, to a
tube amp with a high-impedance input and the
low-impedance input of a power amp. Since the
signal to be split is a low-impedance one, you
can connect low-impedance and high-impedance
inputs behind this if you wish - there won't be any
problems!
What is not possible:
Audible sound losses will occur if you use long ca-
ble routings from the passive guitar to the splitter
and from the splitter to the amps. The total cable
lengths to the splitter and to the amps should
generally not be more than 10m. Your individual
taste will ultimately decide, however.
Splitting your high-impedance instrument signal to
a low-impedance input, such as the line input of
a mixing desk, for example, and to a high-imped-
ance input on a tube amplifier using the Lehle
6
P-Split II will result in the high-impedance input
being attenuated by the low-impedance input of
the mixing desk. The signal will become signifi-
cantly quieter and will totally lose presence.
Solution: these problems can be effectively
eliminated by connecting a preamp or a buffer,
which will convert the high-impedance to a low-
impedance signal, in the signal path. The Lehle
Sunday Driver, for example, can be used here.
