The system accepts inputs from both XLR and 1/4" connection points, and outputs to male balanced XLR jacks. LED indicators for Power, Link, and Data notify you as to the unit's present usage, making it clear whether or not the SRX818SP is on, linked to other speakers via the network, or sending/receiving information to/from other points of access.
