GTBC Aiphone GT Audio Bus Controller
The GTBC is the audio bus controller for Aiphone GT Series multi-tenant intercom systems. It operates from a 24 V DC PS-2420 series supply with 900 mA consumption, common single-pair cabling and a fire-retardant ABS plastic housing.
It is used in the riser or control equipment side of a GT system to support audio bus distribution between entrances and tenant stations. The controller keeps the system audio path organised within the GT bus architecture.
