Palmer - Media DI-Box for PC and Laptop

PRO MEDIA DI/ PLI-04. 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 can be converted to balanced, in order to carry out, e.g., 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 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 that have come to be expected from Palmer.
