SPON NAS-8504B IP PAGING ADAPTER
Features
SPON™ NAS-8504B multi-zone IP paging adapter provides a stereo line output (dual RCA jacks) to a traditional analog amplifier, thereby offering a seamless bridge from IP audio to a legacy analog voice paging/public address system. The line output on the paging adapter can be directly connected to the line input of any 100V constant-voltage analog amplifier with input impedence between 600Ohm to 10kOhm, meaning this device is compatible with most analog amplifiers in the market.
