Loudness Configuration Tab The Loudness Configuration tab allows you to make settings which will determine how Loudness is to be calculated on the Loudness Meter. This tab is shown in Figure 4-8. Figure 4–8: Loudness Configuration Tab AUDIO-2-PLUS The following settings can be made on this tab: 1.
7. Loudness Window: This may be set to Momentary, Short, or one of 22 values, ranging from one second to two hours. 8. Monitoring Mode: a. Manual: Touch the Manual button to enable Manual Mode. This allows you to measure the loudness of a specific program or segment of a program, such as a commercial. In this mode, the Start and Stop button on the Loudness Meter screen can be manually used to begin and end a loudness measurement interval. The reading for that interval is then held on the Loudness Meter. b.
Cancel to discard them. Preset Management Presets are monitoring configurations that can be composed of channels from multiple sources and displayed on the meters in any order. Presets should be set up to allow operators to quickly shift between setups for monitoring. The Preset Management screen contains selections of all of the details for a Preset, and is largely arranged in a matrix format connecting input channels to monitoring channels. The screen is shown in Figure 4-10.
for an SFP module that is inserted, its monitoring inputs will also be muted. Refer to the Licenses section in this chapter to install software licenses. 2. System Clock Reference: There must be a system clock reference for monitoring to take place. Select a reference from the pull down list. The best choice is a stable, always present clock source locked to house sync. Second to that, use the selected input as the clock. Generally speaking, Internal is not the best choice. 3.
of the Cluster changes for the 16 channels, click Reset All. 7. Speaker Assign: Speaker assignments are made automatically when a cluster is set. However, it can be that in an actual signal, the channel assignments may be different than what the automatic assignment assumes. A speaker assignment adjustment is provided for each channel, should you need to override the automatic settings. It is important to accurately assign the function of each channel so that the Loudness calculations will be accurate.
10. The Output Routing tab is shown in Figure 4-12 when the OPT-OUTPUTROUTING capability was not purchased and licensed. This tab shows how signals from the inputs are routed to the outputs. It allows you to view, but not change this default routing. Figure 4-12: Default Output Routing However, if the OPT-OUTPUT-ROUTING license is installed, this tab allows you to determine exactly which input channels are routed to which outputs. It then appears as shown in Figure 4-13.
Figure 4-13: Output Routing Preset Tab 11. When you have finished creating a Preset or making changes to a Preset, either click the Save button to save the Preset, click the Save & Apply button to save the Preset and make it the current Preset, or click the Reset button to discard the changes just made. These selections are shown in Figure 4-13.
Dolby Presets Dolby Presets are useful for customers who want to simultaneously monitor both Dolby decoded channels and other inputs or want to have an auto-zoom to monitor a certain pair that is known to be carrying Dolby encoded audio. Creating a Dolby Preset is in many ways very similar to creating any other Preset. Refer to the Preset Input Routing section of this chapter. Figure 4-14 shows a Dolby Preset being created.
Output Routing The Output Routing licensed feature (OPT-OUTPUT-ROUTING) allows channels to be routed or combined and routed in custom ways to various destination outputs. Output Routing is applied to: 1. Signals monitored using "Input Source select" from the Front Panel, 2. Presets that have been created to apply the Output Routing. Any change to the routing will affect the Presets that have "Apply Output Routing" selected. For example, multiple channels of a 7.
1. Speaker/Headphone: Selected inputs will be sent to the left and right speakers. The default routing is set as per the Speaker Assignment, left channels are sent to the left speaker and right channels are sent to Right speaker. 2. Analog XLR: Selected inputs will be mixed to the left and right channels and played through the two Analog XLR Outputs. 3. AES/Pair-1: Selected inputs will be mixed to the left and right channels and played through the AES Pair 1 Output. 4.
matrix is automatically set to the speaker mix and the checkboxes are grayed out indicating that you may not change them with a Free Mix assignment. Output Options The optional settings in this section allow for customization. 1. Speaker Mix: This option selects whether an output has the Speaker Mix or a Free Mix as set in the Routing Input section. The Speaker/Headphone output is always in the Speaker Mix. 2. Solo/Mute: This setting determines whether or not the outputs are affected by solos and mutes.
3. AES Pairs 1 through 4: The first 8 channels appear on these outputs in numeric order. They are pre-fade, so they are unaffected by the Volume and Balance knobs or headphone insertion. They are also unaffected by the solo/mute selections on the Audio Meter screen. 4. AoIP Pairs 9 and 10: These outputs follow the same configuration as the internal speakers. They are controlled by the Volume and Balance knobs and are muted whenever a headphone is inserted into the Headphone jack.
How do I make the XLR outputs follow the Audio Meter screen solos & mutes while the AES Pair-1 does not? Make the settings shown in the Solo / Mute column: The setting shown above determines that outputs will follow the Audio Meter screen solos & mutes for the XLR outputs because the checkbox is checked. It is not checked for the AES outputs, so they will not be affected by the solo & mute choices. This feature requires the optional OPT-OUTPUT-ROUTING output routing license.
How do I route only specific monitored channels to the Analog XLR outputs? When the optional OPT-OUTPUT-ROUTING license is purchased, you may route specific channels as shown below. Here Audio Meter channels 9, 11, 13, and 15 are routed to the left analog XLR output and Audio Meter channels 10, 12, 14, and 16 are routed to the right analog XLR output. Unchecked channels are not routed. Make sure the Speaker Mix selection is turned off to enable this selection.
the audio will appear on the Analog XLR outputs (for amplified external speakers). Make sure that the Speaker Mix checkbox selection is unchecked for Analog/XLR. How do I ensure that the outputs are automatically muted when the Headphone jack is inserted? When the optional OPT-OUTPUT-ROUTING license is purchased, in the Global Output Routing configuration, if the Mute on Headphone Insertion checkbox is ON then the outputs get automatically muted when a headphone is inserted into the Headphone jack.
How do I ensure that my outputs are pre-faded but follow the solo-mutes on the web interface? This will allow us to monitor only the unmuted/solo Audio Meter channels on amplified stereo speakers connected to the Analog XLR’s. In the Output Routing setting, for the Analog XLR outputs, keep the Volume Control checkbox unchecked and the Solo/Mute checkbox checked. This ensures that the Volume Control is not applied to the outputs, while the Solos/Mutes are.
Once all the units are discovered you may either copy the presets that are currently created on the Master unit or can use an external preset file that you want to copy to any or all of the Target units. Note that any and all of the Presets that may already be contained in each Target unit will be erased by copying the new Presets.

APPENDIX B: Dante Network Setup Introduction Installing the iAM-AUDIO-2 PLUS into an existing and functioning Dante network is virtually plug and play. The iAM rear panel AoIP jack supports 1Gb/s and 100Mb/s Ethernet devices in Dante Audio over IP network configurations. The AoIP option on the iAM-AUDIO-2 PLUS supports Hitless and has 2 RJ-45 interfaces, a primary interface and a secondary interface. Additionally, an SFP slot is provided to receive the AoIP signal using network fiber SFPs.
What is in the iAM-AUDIO-2 PLUS for Dante? The Audinate® Brooklyn II board automatically recognizes DanteTM networks when installed, will alert other devices of its presence and configuration, and will configure its AoIP address per DHCP or local link protocols. There is no need to set a static address for the iAM-AUDIO-2 PLUS Dante port, so no address entry method is provided in the iAM-AUDIO-2 PLUS for Dante network setup.
DanteTM Device Setup The iAM-AUDIO-2 PLUS’s default Dante Device Name is “Wohler- …” followed by the last 6 digits of the Dante port MAC address, as shown in Figure B-3. This name can be changed by the Dante Controller to appear that way on the network, but that will not change the iAM-AUDIO-2 PLUS unit name appearing on GUI pages and iAM-AUDIO-2 PLUS Remote Metering or Discovery pages.
through the Device View menus. Some changes may require remote rebooting of the Brooklyn II card to take effect, temporarily interrupting audio and publishing the new information to the network. Important: Only 44.1 kHz and 48 kHz audio sample rates are currently supported by the iAM-AUDIO-2 PLUS. The Brooklyn II card would accept a Dante Controller command to operate at other rates, without giving an indication it will not be implemented.
AES67 The iAM-AUDIO-2 PLUS Brooklyn II can be configured for AES67 operation. AES67 operation with Dante is limited to eight or less receive and transmit channels at 48 kHz sample rates. 24 bit linear (L24) encoding and 1 msec packet time are fixed default transmit parameters. 16 bit (L16) or 24 bit (L24) encoding and 125/250/333/100 µsec packet times can be received. The Device View - AES67 Config menu enables/disables AES67.
Figure B–7: Device View - Network Config Page 90
The channels to be multicast are selected in the File menu-Create Multicast Flows window shown in Figure B-8. Figure B–8: Multicast Device Lock Audinate recently added a feature whereby a remote controller can send a command to lock Dante network device configurations. The iAM-AUDIO-2 PLUS does not implement the Device Lock command at this time.
Dante Firmware Upgrades Wohler iAM-AUDIO-2 PLUS monitors ship with current Brooklyn II firmware as of the option installation date. The version information is found in the Dante Controller Device View-Status page. iAM software/firmware is tested with the latest Dante code release. Therefore it is strongly recommended that iAM-AUDIO-2 PLUS and Dante software/ firmware be updated at the same time to ensure compatibility and support of the latest features.
APPENDIX D: Ravenna (ZMAN) Setup Introduction Installing the iAM-AUDIO-2 PLUS into an existing and functioning Ravenna network using the Merging ZMAN Card is virtually plug and play. The iAM rear panel AoIP jack supports 1Gb/s and 100Mb/s Ethernet devices in Ravenna Audio over IP network configurations. iAM-AUDIO-2 PLUS channel source selections are made by choosing Input Type ‘AoIP’ in the Configuration-Configure Presets page regardless of which AoIP option is installed.

Merging Ravenna configuration page. Also, the ICON of the card will appear in the main part of the Aneman screen. Double Clicking on the ICON also will load the Configuration screen. For browser access, the URL is .x/advanced/index.html. This brings up the Merging Ravenna configuration page. Each tab is explained in the following sections. Getting Started | General Settings This tab is shown in the following figure.
Getting Started | PTP This tab is shown in the following figure. This configuration page refers to how your Ravenna network is synchronized to clocks. Figure D-2: Getting Started | PTP The elements of this tab are as follows: 1. Global Settings: The default value for PTP a. Domain: For the Merging Ravenna card this value is 0. b. DSCP: 46 for PTP AES67 or 48 for PTP Ravenna. 2. Master: To modify the PTP setting, you must first check the "Manual" checkbox. a. Priority: 1 is the main priority value. b.
a. Lock: This shows if the device is locked to PTP (Locked -Locking Unlocked) b. Master: This is true or false for the current device. c. GMID: This is the current GrandMasterID (PTP Master) d. Delta (ns): This is the time delta between the device and the PTP master. 4. Graph: The graph is only active for slave devices and shows the device delta against Master PTP clock. 5. PTP Priority Value: a. 1 is the highest priority, 255 the lowest one. b.
9. Codec: The possible bit rate values are L24, L16, DSD64, DSD64_32, DSD128, DSD128_32, and DSD256. Note that these values are sampling rate dependent. 10.Frame size (samples): This the frame size of the current source. 11.DSCP: The audio DSCP should be set to 34 for RTP AES67 or 46 for RTP Ravenna. 12.RefClk PTP traceable: This feature is useful when you want to connect a stream through Internet (for example with two PTP Masters (GPS) at each location).
7. Ignore RefClk GMID - accept source locked to any PTP master: This feature is useful when you want to connect a stream through Internet (for example with two PTP Masters (GPS) at each location. This allows making of connections with devices locked to different traceable PTP Masters. See RefClk PTP traceable on the Session Sources tab. 8. Channels: Channel count: The drop-down menu allows selection of specific channel range if the number of channels is smaller than 8. Getting Started | Session Info 1.
Getting Started | Ins/Outs This tab allows you to change the name of the specific Inputs and/or Outputs. Figure D-5: Getting Started | Ins/Outs Getting Started | I/O Router This page allows remapping of incoming channels to different internal channel assignments. For example, Stream channel 1 can be remapped to Merging card Channel 0, and so on.
Operation: Connecting Remote Source to Local Sink This instruction assumes another Ravenna device is active on the network and sourcing a multicast stream. The Merging Configuration section for Session Sink controls how to configure the card to receive the stream and provide it to the iAM interface for display on meters and speakers, etc. The iAM-AUDIO-2 PLUS must be set to receive AOIP from the Source Select Front Panel menu or a browser iAMAUDIO-2 PLUS GUI.
Figure D-7: Session Sinks Tab To avoid confusion if monitoring more than one Flow, especially if the various source Flows have overlapping channel numbers, use the matrix to direct Flows to higher channel ranges. For example, for monitoring 2 SDI sources (four 8 channel Flows), assign two flows to 1-8 and 9-16 and the next SDI signal to 17-24 and 2532. Touch the iAM-AUDIO-2 PLUS AOIP selection menu to select the proper range to monitor, up to 57-64.
ZMAN Session Sources If the ZMAN card is to Source Flows, use the Session Sources tab. Refer to Figure D-8. The procedure is similar to defining Sinks with the additional step to provide the Flow a name to appear on other units in the network. Select the channel range with a maximum of 8 channels per Flow. Figure D-8: Session Sources Tab ZMAN Updating The Zman card is pre-initialized with the correct Wohler firmware load. In case of future upgrades, use the following steps: 1.
