The CP43ARP allows you to connect an APM PA console to the front, while the phoenix connector on the rear allows you to route the signal to the next PA console or breakout box. 

It can provide 20V power to the APM console and is also equipped with 2 jumpers to terminate the audio or data bus. One advantage that the ARP version has over the ARJ version is that it also offers a built-in repeater. This repeater extends the maximum distance from 300m to 600m. This device is also fully compatible with bTicino installation materials.
