EXP1 Device (Discontinued)

The EXP1 is an Expansion Unit available for the legacy HAL1 expansion bus. It adds 8 RAD ports to your HAL System (providing a maximum of 16 additional input and 16 additional output channels. The EXP1 provides power to the RADs while HAL provides a conduit of control. As soon as the EXP1 is connected, its RAD ports become visible and available for configuration from within the Halogen software.

The EXP1 connects to HAL1 via a FireWire cable, which has a maximum length of 15 feet. If you need more RAD ports than are available on the HAL1 device, adding an EXP1 is the solution.

tip: If the additional RAD ports are needed for only temporary channel increases (for example, increasing the number of microphones in a room for a one-time panel discussion), you may want to consider other options such as the AM1 or AM2.
