Introduction

The Yamaha NetworkAmp Manager software is for controlling and monitoring Yamaha PCxxxxN series power ampliﬁers, the ACU16-C Amp Control Unit, and the NHB32-C Network Hub and Bridge. It runs on standard Windows PCs and can be connected to an ACU16-C or NHB32-C by using either USB or RS-232C. Multiple ACU16-Cs and NHB32-Cs can be managed from a single PC running NetworkAmp Manager, which can be connected to any ACU16-C or NHB32-C on the CobraNet network.

NetworkAmp Manager can record log ﬁles listing various operations and warnings (e.g., output shorts, overheating) for troubleshooting analysis after a performance.

Several PCs running NetworkAmp Manager can be connected to the CobraNet network, offering simultaneous control and monitoring from several locations within a venue.

NetworkAmp Manager can control and manage the following:

Up to 512 Yamaha PCxxxxN series power ampliﬁers (32 amps per ACU16-C)

Up to 4,096 ampliﬁer channels (8 channels per ampliﬁer)

Up to 16 ACU16-Cs

Up to 8 NHB32-Cs

What is CobraNet?

CobraNet is technology developed by Peak Audio (Cirrus Logic, USA) that transmits uncompressed digital audio signals in realtime over a fast Ethernet cable. It can carry up to 64 channels in each direction or 128 channels total for both directions (64 channels total for both directions in a network that uses a repeater hub). (However, the number of channels is limited by conditions such as the performance of your equipment and on the type of audio signal.)

Tr ansmission of up to 100 meters is possible with Category 5 metal cable, or up to 2 km with multi-mode optical ﬁber cable.

A CobraNet network can carry digital audio at sampling frequencies of 48 kHz or 96 kHz and 16/20/24 bit resolutions, but the ACU16-C/NHB32-C support the 48 kHz sampling frequency at 20/24 bit resolutions. A ﬁxed latency is added to the audio data each time it passes through a CobraNet network. You can select this latency from 5.33 ms / 2.67 ms /

1.33 ms.

A CobraNet network can carry audio over an existing Fast Ethernet network to which other devices such as computers and printers are already connected, but we strongly recommend that you set up a dedicated network for CobraNet.

In a CobraNet network, digital audio is distributed in packets called “bundles.” Each bundle contains between three and eight channels of audio, depending on conditions such as the bit depth and latency.

Bundles are assigned a number in the range of 0 through 65,279. Bundles can be transmitted either as “multicast bundles” which occupy more network bandwidth but allow audio to be distributed to multiple devices simultaneously, or as “unicast bundles” which use less network bandwidth but can distribute audio to only a single device. The number assigned to the bundle determines which of these two types it is. Number 0 indicates a null setting that disables transmission or reception of bundles, numbers 1 through 255 indicate multicast bundles, and numbers 256 through 65,279 indicate unicast bundles. The ACU16-C/NHB32-C support bundle numbers 0 through 16,383.

The ACU16-C can accept up to four input bundles simultaneously, and the NHB32-C can use four input bundles and four output bundles simultaneously. However if you set the latency to 1.33 ms, the number of bundles usable on the NHB32-C will be a maximum of four (total for input and output).

A CobraNet network also provides a Serial Bridge feature that allows serial data to be transmitted over the network. The ACU16-C and NHB32-C normally use the Serial Bridge to transmit amp control data, but you can also use COM mode or MIDI mode to send other data between two NHB32-C units via the Serial Bridge.

A glossary of CobraNet, NetworkAmp Manager, ACU16-C, and NHB32-C related terms is provided in this manual (see page 39). A wealth of information about CobraNet, with sections especially for designers and installers, is available on the Peak Audio Web site at

http://www.peakaudio.com. If you are designing a CobraNet network, we strongly recom-

mend that you visit this Web site and study the information available in order to take full advantage of the CobraNet technology. Peak Audio also provide a list of Ethernet devices that have been tested with CobraNet, including switching hubs and media converters.

NetworkAmp Manager—Owner’s Manual

Using Multiple PCs

Several PCs running NetworkAmp Manager can be connected to the CobraNet network, offering simultaneous control and monitoring from several locations within a venue.

Up to 16 channels of real-time data (e.g., level meter information) can be transmitted across the network simultaneously. When operating NetworkAmp Manager on several PCs simultaneously, operation of the meter displays on the following pages may be interrupted:

•Amp pages

•Channel Detail page

•Group View page

When one of the above pages is selected, any other PCs displaying one of these pages will automatically switch to its Network page and display the same information. For example, if PC #1 is displaying the Amp 00–07 page, and PC #2 is displaying the Amp 24–31 page, if the Amp 08–15 page is selected on PC #1, PC #2 will switch to its Network page and display the same information. PCs that are not displaying one of the above pages do nothing.

7 Getting Started

2 Getting Started

Installing NetworkAmp Manager

System requirements and installation instructions for NetworkAmp Manager can be found in the printed ACU16-C/NHB32-C Owner’s Manual.

Starting NetworkAmp Manager

To start NetworkAmp Manager, double-click the NetworkAmp Manager icon. If a startup project has been speciﬁed on the General Setup dialog box (see page 8), that project is opened. Otherwise, the Open dialog box appears and you can select the project you want to open. NetworkAmp Manager can also be started by double-clicking a project ﬁle. In either case, the following dialog box appears.

Disconnect from network: Start NetworkAmp Manager but do not connect to the

network.

Connect to network: Start NetworkAmp Manager and connect to the network, getting

the settings of all devices on the network and updating the project settings accordingly.

Connect & send to network: Start NetworkAmp Manager, connect to the network,

and send the project settings to all devices on the network, updating them accordingly.

Caution: Don’t transmit any audio data until all networked devices (ACU16-C, NHB32-C, and power ampliﬁers) have been turned on, the power ampliﬁer’s REMOTE indicators are on, and the system has stabilized (about 10 seconds). Doing so may produce loud noises.

Note: If you change any settings on the Windows Display control panel, NetworkAmp Manager’s windows may not display properly. In this case, you should reset the Display control panel settings to their defaults.

Quitting NetworkAmp Manager

To quit NetworkAmp Manager, choose Exit from the File menu, or click the main window’s Close button. A conﬁrmation message appears. Click Yes to quit. Click No to cancel.

If there are no unsaved changes, NetworkAmp Manager quits. If there are unsaved changes, a dialog box asking if you want to save the changes before quitting appears. Click Yes to save the changes and quit. Click No to quit without saving the changes.
