LEHLE P-ISO XLR TRS
- Isolator, Reamplification box and problem solver
- Absolutely no signal loss or hum
- High-impedance LEHLE TRANSFORMER HZ
- Suitable for balanced or unbalanced signals
- Passive – no need for a power supply
The LEHLE P-ISO XLR TRS combines passive isolation with the highest possible signal fidelity.
Its
applications range from isolation and eliminating hum, to balancing and
reamplification in recording applications along with any signal routing
that requires a clean signal free from noise.
At its core is the
high-end LEHLE TRANSFORMER HZ, which galvanically isolates the signal,
eliminating any possibility of ground loops. The LEHLE TRANSFORMER HZ
was specially designed for use with high-impedance signals but also
processes low-impedance signals with uncompromising sound quality.
The
classic application for the LEHLE P-ISO XLR TRS is as a reamplification
box to eliminate hum noise and unbalancing of the signal. Frequently
background noise caused by ground loops occurs when two grounded
electronic devices are connected to each other.
The LEHLE P-ISO XLR
TRS provides a simple, but extremely effective remedy when installed
between the two units. By using the isolator, the devices are
galvanically isolated and background noise becomes a thing of the past.
Thanks
to its ability to use it in both directions and the choice of balanced
or unbalanced processing, the LEHLE P-ISO XLR TRS is eminently suitable
for many signal types and in numerous situations.
And just in case
you are looking for a power connection: the LEHLE P-ISO XLR TRS performs
all its functions without any need for a power supply. And due to its
optimised size and low weight, it fits easily below your pedalboard or
in any pocket.

The protective earth conductor and the ground connection of the audio signal create a loop which will pick up external interference generated, for example, by coils. Such interference will impair the signal. The LEHLE TRANSFORMER HZ transformer included in the LEHLE P-ISO galvanically isolates the ground connection. The hum loop is thus broken at this point.
