The EXP5x is an Expansion Unit available for the HAL expansion bus. It provides twelve universal analog inputs. Each input supports Balanced Line, Line-Plus, Dynamic Mic or Condenser Mic. The EXP5x also provides four DR ports for Source Selection, Level Control or Toggle/Command functions. In addition, the EXP5x provides power to the DRs while HAL provides a conduit of control. As soon as the EXP5x is connected, its audio inputs and DR ports become visible and available for configuration from within the Halogen software.
As with all the HAL Expansion Units, the EXP5x connects to HAL via a shielded CAT 5e cable which has a cable length maximum of 100 meters (300 feet).
note: The Expansion Bus is a daisy-chain topology supporting up to 32 expansion devices. See HAL1x Expansion Units for details on latency, cable type and cable length.
Universal inputs allow the device to cover a wide range of applications including distributed background music and paging, room combine and auto-mixing. The EXP5x is a cost effective alternative to RAD devices in instances where greater input capacity is required and/or where only analog wiring exists. All Digital Signal Processing typically required to support twelve Mic/Line inputs is provided by fixed processing blocks in the EXP5x as shown below:
