Shure SCM268 Mixer

Six Reasons the SCM268 Is The Right Choice: Transformer. Transformer. Transformer. Transformer. Transformer. Transformer. Great Value The competitively-priced SCM268 microphone mixer features six transformers inside: four transformer balanced XLR microphone-level inputs, one transformer balanced XLR mic/line output, and one internal low stray field, toroidal power transformer. Many Benefits, Little Space All those audio transformers provide protection from RF interference, prevent ground loops, and make the SCM268 exceptionally quiet. The internal toroidal power transformer means you no longer have to deal with that annoying "wall wart." Add to this a rugged half-rack chassis -- with exceptionally solid rack mounting hardware -- and the SCM268 will easily fit into the widest range of smaller applications.,
