PLI-04 Media DI-Box for PC and Laptop
PLI-04 Media DI-Box for PC and Laptop
With the new PRO MEDIA DI PLI-04, Palmer introduces a DI-box produced with the discerning needs of the computer-age media in mind. Using this uncomplicated method, personal computers and other consumer equipment with unbalanced outputs (including 1/8" stereo headphone jacks) can be converted to balanced, in order to facilitate a presentation over a professional PA system.

The PLI-04 accommodates all the common input types: TRS jacks accepting mono or stereo plugs, RCA phono sockets and a 3.5mm stereo jack input for use with the headphone output of a laptop, iPod or similar device. The outputs are conventional transformer balanced XLR sockets, as used in professional PA systems, guaranteeing an electrically decoupled signal, a prerequisite to ensure noise-free operation.

One other special feature which should not be forgotten! Although the PLI-04 is primarily a stereo unit, it can be switched to mono with the two stereo signals summed and fed to both XLR outputs.

The PLI-04 manifests a mechanically robust unit combined with outstanding technical specifications, adding to the list of high quality products the Professional community has come to expect from Palmer Pro Audio Tools.
