In the installation sector, classic XLR-plug connectors are frequently impractical because for one thing they have to be soldered on site and for another they also require substantial space in the depth dimension. Thus the connectors know in technical jargon as Phoenix clamps are encountered much more often. The connection is pluggable on the one hand and the connections are screwed and not soldered. With the PRM-PHOENIX, Palmer is providing a 19" 1 U unit that is equipped with various high-quality transformers and solves ground loops and signal splitting problems. Same features as LINE SPLIT, but transformers optimized for MIC level and impedance. Moreover, a resistance matrix for signal decoupling is included.
