32 System Examples 4 System Examples ACU16-C Power Amp Control System This example shows how up to 32 Yamaha PCxxxxN series power amplifiers can be connected to a single ACU16-C for remote control and monitoring via NetworkAmp Manager.
33 ACU16-C/NHB32-C CobraNet Audio Distribution System This example shows how multiple AES/EBU channels can be distributed over long distances (up to 200 meters with 100Base-TX Ethernet cabling) to multiple power amplifiers. The NHB32-Cs handle AES/EBU to CobraNet conversion, while the ACU16-Cs handle CobraNet to analog conversion. Power amplifier control and monitoring can be performed on either PC.
34 System Examples MIDI Over CobraNet This example shows how MIDI mode, which is set in NetworkAmp Manager, can transmit MIDI Program Change and Control Change messages from one NHB32-C to another over CobraNet’s Serial Bridge feature. In this example, MIDI data from a Yamaha DME32 Digital Mixing Engine is fed through to a Yamaha DM2000 Digital Production Console. While MIDI mode is active, neither Amp Control data nor AD824 data can be transmitted. ex. Yamaha DME32 ex.
35 CobraNet Primary & Secondary These two examples show how the CobraNet PRIMARY and SECONDARY ports can be used to build redundancy into systems. In the first example, if a primary connection fails, the system automatically switches to secondary and operation continues uninterrupted. However, if the switching hub fails, the entire system stops working.
36 Troubleshooting Troubleshooting Unit Symptom Cannot power up? Cannot establish a connection with NetworkAmp Manager? Advice Make sure that the power cord is connected to a suitable AC wall outlet. Also make sure that the other end of the power cord is connected to the unit’s AC IN correctly. Use the supplied retaining clamp to ensure that the power cord cannot be disconnected inadvertently. Make sure that the POWER switch is set to the ON position.
System Errors ACU16-C NHB32-C NetworkAmp Manager Symptom Advice NetworkAmp Manager cannot control and monitor all power amps? Make sure that all power amps are powered up. Make sure that each power amp is assigned an exclusive amp ID. Check the RS-485 cable connection between each power amp. If a cable is not connected properly, or a cable is faulty, power amps further down the line will not be detected.
