Taking control to the next level, the ALPS-3 broadcast audio processor features full remote-control via both GPI and Internet (IP). For situations where audio parameters need to be changed on a regular basis, fully-flexible scheduling software is provided. All processing parameters can be remotely altered by automation systems to reflect changes in broadcast content.

Part Number: ALPS-3 (USB & RS232, front panel control + IP, scheduling, GPI, 99 pre-sets)
