The significantly enhanced HAL1x Expansion Bus ships in the new EXP1x, EXP3x & EXP5x in April 2013. The new Bus supports daisy-chaining any combination of up to 32 EXPs, allows 512 x 512 audio channels, permits EXPs to be 100 meters (328 feet) apart, and supports unmanaged gigabit media converters (fiber) if EXPs need to be miles apart. This allows spreading HAL system audio and control I/O between distant equipment rooms in conference centers, campuses, classrooms, hotels, malls, arenas, sports centers, water parks, among others.
No Ethernet switches required. Just dedicated shielded CAT 5e or better cables or fiber, daisy-chained between EXPs. Yes, daisy-chained.
The EXP3x Output Expander feeds audio into 8 zones, including 6 control DR remotes and distant RAD audio I/O such as jacks for the band or DJ to plug in. Daisy-chaining 32 EXP3x devices to a single HAL1x supports 256 background music and paging zones.
A single EXP5x Input & DSP Expander handles conference rooms needing ten auto-mixed mics, two line sources, and four DR control remotes. A stack of EXP5x devices with one HAL1x can tackle a couple dozen such rooms. Up to 32 EXP5x devices provides several dozen small rooms needing a few mics, a line or two, and a remote control each.
