Electro-Voice EVI-AC EV Innovation Access Card

Reduce service time and minimize downtime with the Electro-Voice EVI-AC Access Card, a plug-in loudspeaker test board designed for fast, non-invasive diagnostics. This Electro-Voice smart card gives AV integrators and field technicians direct access to transducers and internal protection circuitry without disassembling the enclosure. The EVI-AC (manufacturer part number EVI-AC) is compatible with EV-Innovation (EV-I) series two-way loudspeakers and supports typical DCR measurements used to verify driver health and circuit integrity.

Installed in seconds, the compact test board simplifies troubleshooting for AV, security, surveillance and monitoring deployments — from house-of-worship sound systems to corporate conferencing and public-address installations. By avoiding cable disconnects and internal access, it preserves factory seals and reduces the risk of damage during maintenance. Use the Electro-Voice EVI-AC to speed field diagnostics, confirm transducer continuity, and validate protection-circuit operation with repeatable results. Ideal for integrators, service teams and systems technicians responsible for audio performance and security audio monitoring. Add the EVI-AC Access Card to your toolkit to streamline maintenance and improve uptime.
