EV- Innovation
The plug-in card system is a unique feature of the EV-Innovation family of 
loudspeakers.  This simple device (EVI-AC) allows diagnostic access to 
the transducers and protection circuitry inside the enclosure WITHOUT 
requiring any disassembly or disconnections beyond simple removal and 
replacement of the plug-in passive/bi-amp switch card.  The EVI-AC 
works with all EVA, EVF and EVH two-way and low-frequency systems 
with plug-in card.
