The EXP2x is an input/output expander that enables the HAL1x to send 32 and receive 32 audio channels from other Dante™ devices.
A HAL1x Multiprocessor supports 16 in x 16 out audio, with 8 in x 8 out on balanced analog connections, and another 8 in x 8 out through RADs.
The EXP1x adds eight RAD ports to a HAL1x via the Expansion Bus. The EXP1x requires a HAL1x to operate.
The EXP3x is an 8-channel analog output & DSP expander for the HAL1x (required for operation).
The EXP5x is a 12 Mic/Line/Line-Plus input & DSP expander for the HAL1x. It also supplies four DR ports, useful for adding source selection and/or volume control remote controls.
The Rane EXP7x Expander for the HAL1x provides eight channels of full-featured, drag and drop Acoustic Echo Cancellation (AEC). Each channel of AEC can be added to any HAL1x system input and route to any Halogen DSP block, including the gain-sharing automixer, manual mixer, regular Room Combine block, or Conference Room Combine block.
