Analog RCA and digital TOSLINK to balanced analog audio. The module could be powered over the bus, or if connected directly to a power supply, it adds both power and audio to the EAS-bus.
The EAS-TX-DA converts digital audio (TOSLINK) or unbalanced analog audio (RCA) to balanced analog audio and sends it over the EAS-bus.

The EAS-TX-DA is typically used in one of two ways:
Looking at the illustration above, you’ll see that both power and audio gets connected to the EAS-TX-DA, for it all to melt together into one EAS-bus. You don’t have to connect a power supply, but then a power source needs to be provided elsewhere alone the same EAS-bus.
From here, the EAS-bus has everything it needs, so this unit alone with an amplifier and some speakers can be a system by themselves.
The module is expecting line-level signals. If the incoming signal is on the low side, you might want to consider gaining it up a bit. Use the following dipswitch settings to obtain the desired level of boost:
To utilize the 0-volt instant mute trigger, it’s a simple matter or shorting the two pins inside the Phoenix connector. There should be corresponding 0-volt interfaces on the 3rd party fire alarm system, so it will be a basic one-to-one connection between the Phoenix connector and the alarm unit.
