Our broadcast paging module is the heart of each GAI-TRONICS’ Tower Broadcast product. This series device receives the broadcast audio via 600 Ohm telephone pair, RF frequency, or both, and provides high-efficiency amplification for speaker broadcasts. Note: The 10458-102 is ordered as part of a 234SBA Stanchion Broadcast Assembly or 234SBM Stanchion Broadcast Module. It should be ordered separately only for spare part purposes.
