Details
Controls: Card-based modular configuration (no dedicated front-panel mix controls; mixing happens at each Mixer unit)
I/O: Analog Input Card: 8 balanced inputs on DB-25 female (DA-88 pinout) per card; Digital Input Cards: Dante, ADAT, AES/EBU, Waves SoundGrid, or MADI (16-32 ch depending on protocol); HBUS In/Out (RJ45) for daisy-chaining Hubs; 8-pin RJ45 x8 per network card to Mixers
Notes: device_class judgment call: classified as Stagebox / Expander per field guidance ("a hub/distributor/snake or I/O expander"); this is the rackmount, card-based hub half of the two-part Hear Back PRO system (Mixer classed separately as Personal Monitoring). dsp=false because the Hub itself does not mix, it routes/distributes; per-user mixing occurs in each Mixer. Latency figures from manufacturer: analog-in to analog-out 0.248ms, digital-in to analog-out 0.092ms, digital-in to digital-out 0.0452ms (all @192kHz).

Price not published by manufacturer; left blank rather than use conflicting/uncertain third-party bare-mainframe listings. country_of_manufacture=USA per manufacturer background info, not explicit on this page.
