Configuration Settings Tab Parameters
The easiest way to configure Nyquist appliances is to obtain configuration settings from the Nyquist server by selecting Get Configuration From Server. However, you can manually configure an appliance through the appliance’s Web UI when Standalone Operation is enabled (see"Standalone Operation Configuration Settings").
To view or modify the Nyquist appliance configuration:
1 On the appliance Web UI’s main page, select Configuration Settings.
2 View the settings as described in Table 5 for normal configuration, or modify the settings as described in"Standalone Operation Configuration Settings" for Standalone Operation configuration.
3 If changes were made (Standalone Operation only), click the Save Configuration Settings and/or Save Multicast Addresses buttons to save your changes.
The following table describes the Configuration Settings tab settings when Standalone Operation is not enabled for this device:
Get Configuration from Server | Retrieves configuration settings (i.e., web username, server, and local port) from the TFTP server specified in the Network Settings (see"Network Settings Tab Parameters"). |
Web Username | Displays the username of the current user. |
Emergency-All-Call | Identifies the IP address, port number, cut level (volume), and station list used for emergency all-call pages. |
All-Call | Identifies the IP address, port number, cut level (volume), and station list used for all-call pages. |
Audio Distribution | Identifies the IP address, port number, cut level (volume), and station list used for audio distribution. |
Multicast # | Identifies the IP address, port number, cut level (volume), and station list used for the multicast audio stream of one (or more) zones. |
The Configuration Settings tab also displays following information for each Device Station attached to the amplifier:
Port Number | Shows the output port of the amplifier, where 1 = A, 2 = B, 3 = C, and 4 = D. |
Port Type | Shows the device type to which the port connects. |
Account ID | Shows the SIP account (IP address) associated with the device preceded by the extension of the device associated with this port. |
Local Port | Shows the port used for SIP. |
Username | Shows the username or extension for the station associated with the port. |
Standalone Operation Configuration Settings
The following table describes the Configuration Settings tab settings when Standalone Operation is enabled for this device:
Device Type | Displays the type of this device. |
Device Name | Provide a name for this device. |
Web Username | Provide a web username for this appliance. |
Web Password | Provide a web password for logging into the appliance. |
Web Confirm Password | Re-enter the password used to log into the appliance. |
Time Zone | Select the time zone in which the device resides. |
Prioritize Line Input | If a channel simultaneously receives input signals from both a network input and a line input, “Yes” means line input is used, “No” means network input is used. Yes or No |
Channel A/B/C/D Load Impedance | Specify the impedance load of the connected speaker(s). Low (typically 4-16 ohms) or High (typically 1000+ ohms) |
Channel A/B/C/D Output Power | Controls the output power to the speaker. This can be a value from -6 to +6 dB. |
Enable SIP Calls | Enables this device to receive one-way SIP calls, wherein only the caller can be heard (such as announcements). If enabled, a number of SIP-related configuration settings are displayed. Yes or No |
SIP Server Addressa | Specify the IP address of the SIP Registration Server with which the device will register. |
SIP Network Porta | Specify the IP port on which to communicate with the SIP Registration Server (typically 5060). |
SIP Codecsa | Displays a read-only list of codecs allowed on SIP sessions. |
SIP Extensiona | Specify the SIP extension corresponding to Channel A, B, C, or D. The extension, along with the IP address, is used to specify the URI used to place a SIP call to this extension: sip:<extension>@<local_ip_address> |
SIP Usernamea | Specify the SIP username used to register Channel A, B, C, or D with the SIP server. |
SIP Passworda | Specify the SIP registration password used to register Channel A, B, C, or D with the SIP server. |
Cut Levela | Specify the intercom volume to be used for SIP calls over Channel A, B, C, or D. This can be a value from -42 and 0 dB. The default value is -20 dB. Note: To modify, click on the value, adjust the slider on the popup using the cursor keys or mouse, and click the check box button. |
The following parameters appear for each Multicast Address configured for this device.
Multicast IP Address | Specifies the multicast IP address on which to receive audio streams. |
Multicast Port Number | Specifies the multicast port on which to receive audio streams. |
Codec | Specifies the codec to be used when decoding audio. Select one of the following values: G711 u-law Intercom quality A narrowband audio codec that provides toll-quality audio at 64 kbps. The u-law version is primarily used in North America and Japan. G711 a-law Intercom quality A narrowband audio codec that provides toll-quality audio at 64 kbps. The a-law version is primarily used in most countries outside of North America and Japan. G722 Tone and paging quality A wideband audio codec operating at 48, 56, and 64 kbps. OPUS Music quality An audio codec format designed for speech and general audio, supporting low latency, constant and variable bitrate encoding (6 to 510 kbps), and five sampling rates (from 8 to 48 kHz). |
Channels | Channel(s) on which the audio streams will be output. One or more of the following values: Channel A Channel B Channel C Channel D |
Cut Level (dB) | Specifies the cut level for the audio stream. This can be a value from -70 to 0 dB. The default value is -20 dB. Note: To modify, click on the value, adjust the slider on the popup using the cursor keys or mouse, and click the check box button. Tip: To fine tune the level per channel, adjust the levels on the DSP mixing board interface. |
Note: A maximum of 24 multicast entries is supported. |
Note: Multicast Addresses should be ordered by priority, highest priority first. If multiple streams are active on the same channel simultaneously, the one with the highest priority will be played. Set the Sorting switch to Enabled and drag entries using the 4-way arrow symbols to drag entries up and down to rearrange the priorities. |
