Item Part Number:



The PG32-AES device offers four principal ports for connection and transport of a total of 32 AES/EBU digital audio channels, ie 64 mono channels. The 4 x DSub25 ports with eight channels can be assigned as AES/EBU inputs or AES/EBU outputs in groups of four. The PG32-AES can be used as an interface to all microphone pre-amps with AES3 outputs. It serves as I/O to the converter devices to PG-Audio FX devices or via SANE to PG-Audio TP devices. Using ProGrid microphone preamps, the PG32-AES enables direct gain control of the preamps from most digital consoles, including Yamaha, DiGiCo, Soundcraft, Studer, Lawo or SSL digital consoles. Devices include dual power supplies with automatic switchover.
