pedance inputs have input impedances
of around 600 Ω to 10 kΩ.
WHAT IS POSSIBLE
The LEHLE P-SPLIT III can be used to split
the signal from an electric guitar or elec-
tric bass with passive magnetic pickups to
two amplifiers, each of which has high-
impedance inputs. Please use the short-
est, best-quality possible cables for this
purpose. You will hear the 100% original
signal on both amps.
Instead of an amplifier, you can also split
the signal to the Hi-Z input of a sound
card.
It’s important to remember: a high-im-
pedance 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 II or the out-
put 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 cable routings from the passive gui-
tar to the splitter and from the splitter to
the amps. The sum of all cable lengths to
the splitter and to the amps should gener-
ally not be more than 10m.
Your individual taste will ultimately de-
cide, however.
Splitting your high-impedance instrument
signal to a low-impedance input, such as
the line input of a mixing desk, for exam-
ple, and to a high-impedance input on
a tube amplifier using the LEHLE P-SPLIT
III will result in the high-impedance input
being attenuated by the low-impedance
input of the mixing desk. The signal will
become significantly quieter and will lose
presence.
Solution: these problems can be effec-
tively 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 II, for exam-
ple, can be used here.
