School Sound Amp Processor The TERRA-SAP is a networkable processor equipped with 2 channels amplifier x 20 Watt. It also acts as an audio hub for local connected devices such as mic/line inputs, USB interface for message / music storage and playback, and the connection with audio-visual devices such as projectors as well as logic input / outputs.

Local volume control and audio input selection can be managed using RAC5 or RAC8 source selector & volume control remote. In case of an emergency, press the supervised EVAC button on Terra-SAP in order to alert the central monitoring station to respond to an incident.

The TerraManager Graphical User Interface (GUI) software brings all together by facilitating full control, paging, intercom, messaging, recording, streaming, audio routing, device I/O monitoring, and bell scheduling with the greatest ease. Communication between administrative staff and classrooms can be quickly established whether it is a district wide school intercom, campus paging, messaging/BGM distribution on multiple stores, and so on.
