AuviTran AVNF49-ES + Nexo NXAmp

Unique monitoring features

EtherSound connected NXAmps can provide important information about its internal parameters for the system, such as:

Impedance over a specific threshold for each channel

Impedance under a specific threshold for each channel

Temperature limit overrun for each channel

The combination NXAmps + AVNF49-ES provides unique supervision features about the amplification system

NXAmps are also equipped with GPIs and GPOs, and can communicate through that for actions
