This is the user manual for Yamaha ACU16-C/NHB32-C. It introduces the features and usage methods of the device.
This document serves as an addendum and update to the original Owner's Manual for the Yamaha ACU16-C and NHB32-C system. It details changes and corrections resulting from a system software upgrade to version 1.10, specifically regarding CobraNet latency settings and channel distribution limits. The text also corrects previous information concerning cable lengths, system requirements for the NetworkAmp Manager software, and redundancy configurations for primary and secondary ports.
| Maximum CobraNet channels (8 units) | 256 channels |
|---|---|
| Maximum AES/EBU channels (8 units) | 256 channels |
| Maximum cable length (Ethernet) | 100 m |
| Maximum cable length (Multimode fiber) | 2 km |
| Minimum rack ventilation gap | 1U (4.5cm) |
| Minimum fan airflow | 1.6m³/min |
| Minimum fan static pressure | 5mmH₂O |
The latency setting can now be selected from three choices: 5.33 ms, 2.67 ms, or 1.33 ms.
No, all CobraNet devices in a single network must have the same latency setting to communicate correctly.
The system automatically switches to the secondary port, though the audio signal will be momentarily interrupted.
Up to eight NHB32-Cs can be used on a single CobraNet network.
