    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.

  • Page 5: What Is Cobranet

    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.)

  • Page 6: Using Multiple Pcs

    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.

    NHB Pages 4 NHB Pages This chapter explains the NHB pages, which can be selected while an NHB32-C is selected in the network tree. Devices on a CobraNet network transmit and receive audio data by matching bundle num- bers. Matching the bundle number on the transmitting and receiving devices is analogous to making a physical cable connection between two devices.
  • Page 16 intensify the restrictions on Ethernet’s packet delivery times, and therefore reduce the max- imum number of switches that can be used. For details, refer to the Peak Audio website (http://www.peakaudio.com). Note: If the latency is 1.33 ms, the number of bundles that can be handled by this single device on a CobraNet network will be limited to a total of four bundles for transmission and reception.

  • Page 17: Patch Page

    NHB Pages Patch Page This page is used to assign AES/EBU inputs and outputs to individual CobraNet channels and to store and recall assignment patches. Before making any assignments, you must spec- ify the bundles that contain the CobraNet channels you want to patch (see AES/EBU inputs and outputs are assigned to CobraNet channels on two 32 x 32 grids, one for inputs, one for outputs.

    AES/EBU In to CobraNet: channels. CobraNet to AES/EBU Out: outputs. Store/Recall: These buttons are used to store and recall patches. A patch consists of all AES/EBU input and output to CobraNet channel assignments. There are 100 patch mem- ories. Patch #0 is a read-only memory containing initial assignments, with each AES/EBU input and output assigned to the correspondingly numbered CobraNet input and output.

    ACU Pages 5 ACU Pages This chapter explains the ACU pages, which can be selected while an ACU16-C is selected in the network tree. Devices on a CobraNet network transmit and receive audio data by matching bundle num- bers. Matching the bundle number on the transmitting and receiving devices is analogous to making a physical cable connection between two devices.

    Note: If two or more latencies exist within a CobraNet network, there is a danger that the devices may become unable to communicate correctly with each other. You must make the same latency setting for all devices in a single network. Note: If you are unable to change the latency, refer to Troubleshooting (see Patch Page This page is used to assign individual CobraNet channels to ACU16-C analog outputs.

  • Page 21: Amp Pages

    ACU Pages Amp Pages The Amp pages are used to control and monitor power amplifiers. There are four Amp pages: Amp 00–07, Amp 08–15, Amp 16–23, and Amp 24–31. Each page can display the channels of up to eight power amplifiers. Power amplifi- ers can have 2, 4, 6, or 8 channels.

  • Page 22: Channel Detail Page

    Channel Detail Page The Channel Detail page offers a detailed view of each channel. It can be opened by clicking the Channel Detail tab while an ACU16-C is selected in the network tree, or by clicking a power amplifier channel icon in the network tree. PROTECT indicator Channel select:...
  • Page 23 ACU Pages Mode indicator: REO, PARALLEL, or BRIDGE. ATT fader: This fader attenuates the channel’s input signal. The numerical value below the fader is the current attenuation setting in dB. Attenuation can also be set by clicking the Up and Down arrow buttons, or by entering a value from the keyboard. Phase button: Reversed.

  • Page 24: Threshold Page

    Threshold Page This page is used to specify the wattage, temperature, and the minimum and maximum load impedance thresholds at which you want NetworkAmp Manager to issue a warning. The thresholds can be set individually for each power amplifier channel. Warnings are dis- played in the Log window and recorded in the log file.

  • Page 25: Other Functions

    Other Functions 6 Other Functions Logging Events NetworkAmp Manager compares the threshold values set on the ACU Threshold page (see page 24) with the amp’s operating status and issues a warning if a value is exceeded. Warn- ings are displayed in the Log window (see CSV format text files that can be opened by any text editor, word processor, or spreadsheet.
  • Page 26 Logging Events There are five types of event: Warning, Online/Offline Status, Power Switch, Error, and Net- work Mode. These are explained below. 1 Warning Event This type of event occurs when a specified threshold is exceeded (see page 24).

  • Page 31: Using Com & Midi Modes

    Other Functions Using COM & MIDI Modes CobraNet’s Serial Bridge feature allows serial data to be transmitted over the network. Nor- mally, the ACU16-C and NHB32-C use the Serial Bridge to transmit amp control data. However, it can be used to transmit MIDI data (Program Change and Control Change) or AD824 head amp control data between any two NHB32-Cs on the network.

    Glossary Glossary This glossary contains terms relevant to NetworkAmp Manager, the ACU16-C, and NHB32-C. 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 network, we strongly recommend that you visit this Web site and study the information available in order to take full advantage of the CobraNet technology.

  • Page 41 The structure of a network. Common network topologies include The devices on a CobraNet network that are wordclock slaves. Performers A basic network hub that retransmits all incoming data to all of its output The type of connector used to connect 10Base-T, 100Base-T, and CobraNet supports a single sampling rate of 48 kHz.
  • Page 42 Glossary Unicast bundle: CobraNet bundles 256~65,279 are unicast bundles. (However since the ACU16-C/NHB32-C support only bundle numbers 0~16,383, they can only use unicast bundles 256~16,383.) In other words, these are transmitted only if the two devices are set to transmit and receive that specific bundle. Unicast bundles only allow point-to-point con- nections and as such are far more bandwidth efficient than multicast bundles.
