EXP2x Device

The EXP2x is a Dante Expansion Unit for the HAL1x expansion bus. Each EXP2x adds 32 Dante Receive and 32 Dante Transmit audio channels to your HAL System at up to 96 kHz sample rates. The EXP2x provides automatic sample rate conversion for easy integration to the 48 kHz world of HAL audio with a Dante network at 44.1, 48, 88.2, or 96 kHz. Like all Dante devices, the Dante Receiver and Transmitter pair must be set to the same sample rate and latency within Dante Controller in order to subscribe or connect to each others’ audio. As soon as the EXP2x is connected, its Dante channels become available for use from within the Halogen software.

EXP2x Basics & Rane’s Dante set up philosophy

The EXP2x also provides two Dante Network jacks: Primary and Secondary. Using Dante Controller software, you can configure the Secondary connection to operate in Switch or Redundant mode. When in switch mode, the secondary port works in parallel with the primary. In redundant mode the secondary port is a fail-over connection to the Dante secondary network, which is a physically separate network from the Primary Dante network.

note: Unlike other expansion devices, names and most settings of the EXP2x are read-only in Halogen software. Configure EXP2x device name, audio channel names, audio routing, secondary Ethernet port mode, latency, and other settings using Dante Controller software, available from Audinate. When connected these read-only settings can be viewed from the EXP2x hardware dialog.

As with all the HAL1x Expansion Units, the EXP2x connects to HAL via a shielded CAT 5e (or better) with 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.
