LI 05

Balanced or unbalanced? That’s not a problem with the BALUN/PLI05. BALUN stands for balanced-unbalanced. This means that because the PLI05 uses TRS (stereo) jack sockets, both the input and output can be operated balanced or unbalanced. The PLI05 is the PLI02’s little sister. Both speakers can be used to convert from balanced to unbalanced. Both speakers include line isolation transformers for galvanic isolation. They are connected between mains-operated audio devices to prevent ground loop hum. The PLI02 is designed for using XLR connectors and built for low impedances (600 ohm). In contrast, the use of jack sockets means that the PLI05 is better suited to higher impedances. It can be operated in the broad range of 600 ohm to over 10 kilo ohm. However, in order to minimise level loss, the input impedance should not be lower than the output impedance.
