The EXP3x is an 8-channel analog output & DSP Expansion Unit for the HAL1x expansion bus. It adds full support for eight zones of distributed background music and paging, including 2 RAD ports, 6 DR ports and all of the required digital signal processing. The EXP3x provides power to the RADs and DRs while HAL provides a conduit of control. As soon as the EXP3x is connected, its audio outputs, RAD and DR ports become visible and available for configuration from within the Halogen software.
As with all the HAL1x Expansion Units, the EXP3x connects to HAL via a shielded CAT 5e with a cable length maximum of 100 metres (300 feet).
