A Line Isolator Designed for Stage and Studio Constraints
The PLI-02 is a professional line isolation box designed to be placed between audio devices connected to mains power, when facing common issues such as hum, ground noise, or interference caused by ground loops. In a live environment where multiple devices share different power supplies, or in the studio when multiple racks and interfaces coexist, this type of isolator becomes a simple and effective tool to stabilize a system. Its 2-channel format allows intervention on a stereo pair or two independent lines without multiplying boxes.
Who It's For and Its Uses
The PLI-02 is aimed at musicians, sound technicians, studio engineers, and anyone needing to secure an audio chain without changing the overall routing. It is particularly relevant if you connect a mixer, an interface, a player, a processor, or any audio device likely to generate noise when connected to other equipment powered from the mains. It can also be useful when you need to adapt an unbalanced output to a balanced connection to better handle long cable runs and the electrical environment of a stage.

Questions frequently asked
Does the Palmer PLI 02 Pro eliminate ground loop hum?
The line isolation is designed to reduce hum, ground noise, and interference caused by ground loops between mains-powered devices. A ground lift switch allows selection of the quietest configuration.
Can a stereo keyboard be connected to this isolator?
The 2 channels allow processing a stereo keyboard output in a single unit. Each channel has a combined Neutrik input and a male XLR output.
6.35 mm jack input and XLR output: is this compatible?
An unbalanced source connected via a 6.35 mm jack can be routed to a balanced male XLR output. The unit provides unbalanced to balanced conversion.
What signal level does the PLI 02 Pro accept?
The maximum accepted level reaches +20 dBu at fixed gain. This value corresponds to use with stage or studio audio equipment.
Can it isolate two independent mono lines?
Each channel can be used separately for two mono connections. The combined XLR/6.35 mm jack inputs facilitate connection of sources with different connectors. Both outputs are male XLR format.
