In Wall Audio Power Amplifier


In Wall Audio Power Amplifier

UP1812A module is Class D power amplifier with volume control on the front panel, connecting with CSP transceivers and receiving the audio signal from pair B and C of UTP RJ-45. When the volume control is set to minimum, the UP1812A will go to standby mode. The output and power in terminal is designed at the back panel, and allows to connect with 4 Ohm or 8 Ohm loudspeaker.
UP1812A module could be powered from a 24VDC power supply by using the rear panel terminal block, or powered from the connected CSP transceiver module.

The power also could be provided to all the connected modules by Pair D of UTP CAT5 cable.
