Hear Technologies OCTOHBH Hear Back OCTO Hub
The modular Hub consists of four card slots, which can be populated with any configuration of input and/or output cards to fit your exact needs. Each Hub has the ability to supply signal and power to as many as 32 Mixers (8 per Network Card), each over a single standard CAT6* cable. With the built-in HBUS In/ Out ports, multiple Hubs can be daisy-chained together, allowing for truly unlimited system expansion.
Key Features
- Allows 32 channel digital input cards (e.g., Dante, Waves, MADI)
- Up to 32 input channels per Hub
- Multiple Hubs daisy-chain for up to 128 input channels
- Mix and match input types (ex. Dante and Analog)
- Six user-selectable sample rates indicated by LEDs: 44.1kHz, 48kHz, 88.2kHz, 96kHz, 176.4kHz and 192kHz
- Analog, Dante and AES/EBU goes up to 192kHz
- ADAT – goes up to 48kHz (SMUX not supported; ex. ADAT will down sample from 192kHz to 48kHz)
- Waves – goes up to 96kHz
- Less than .25 milliseconds total system delay (latency) from analog input to output
- 16 RGB LEDs intuitively display signal/peak levels for channel metering
- Standard CAT5e/6 cabling delivers power and signals to Mixers
- Daisy-chain via HBus for very large systems
- 1 RU chassis
- Modular I/O card-slot configurable mainframe
- Gigabit Ethernet network fabric
- 48V Power Over Ethernet supply
