RCA Level Input - Output
Commonly used to solve noise problems in car audio systems.When utilizing the L.O.C.PRO™ LPGL-2 for RCA
input/output connect the male and female adapters to the LPGL-2. These can be reversed if connecting at the radio
or the amplier. Most applications will not require connection of the ground wires. If noise is still present, on a clean
grounding point, try temporarily connecting one ground at a time. Then alternating between the two and nally
connecting both. Test the system and permanently make the connections with the best sounding conguration.
Mount the LPGL-2 using wire ties, screws or double tape.

3.5mm Audio to 3.5mm Audio
Commonly used when using a Smartphone as a 3.5mm audio input and noise enters phone through the phone
charger. When utilizing the L.O.C.PRO
™
LPGL-2 for 3.5mm input/output disconnect the original 3.5mm cable and
connect it to the input of LPGL-2. Then connect the included 3.5mm output cable to the original input point and the
output from the LPGL-2. Most applications will not require connection of the ground wires. If noise is still present,
on a clean grounding point try temporally connecting one ground at a time, alternating between the two and nally
connecting both. Test the system and permanently make the connections with the best sounding scenario.
