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

NetworkAmp Manager—Owner’s Manual

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.)

Transmission 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 transmit-

ted 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 multi-

cast 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 trans-

mitted 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 sec-

tions 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.

Using Multiple PCs 6

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 simul-

taneously, 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.

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.

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 Man-

ager’s windows may not display properly. In this case, you should reset the Display control

panel settings to their defaults.

Conﬁguring NetworkAmp Manager

The General Setup dialog box is used to conﬁgure NetworkAmp Manager. To open the

General Setup dialog box, choose General Setup from the Option menu.

PC I/F for amp control: These options are used to specify the MIDI interface Net-

workAmp Manager should use to communicate with the connected ACU16-C/NHB32-C.

The options available depends on what MIDI drivers you have installed on your PC.Choose

the Yamaha CBX Driver (for use with serial ports) or Yamaha USB Driver (for use with USB

ports). See the ACU16-C/NHB32-C Owner’s Manual for information on installing these

drivers.

Control error caution: When this option is selected, a message is displayed in the Log

window when a parameter is adjusted on another PC or an ACU16-C or NHB32-C.

Default project: These options determine how NetworkAmp Manager behaves when it’s

started. When “None” is selected, the project open dialog box appears automatically and

you can select a project ﬁle manually. When the “Speciﬁed project” option is selected, the

speciﬁed project is opened automatically. Click the Browse button to select the project ﬁle

to be opened automatically. If you enter the ﬁlename manually, be sure to include the full

path (e.g., C:\My Documents\NetworkAmp Manager\My Project.apj).
