How Do I Set Up for External Surround Sound? If a studio or other monitoring environment contains a surround sound system, it may be advantageous to connect the monitored sound from the AMP2-16V Series monitor to this system. Up to six pairs (12 channels) of analog or AES outputs are available for this use.
Page 34
5. Analog output cards have only 8 outputs. In order to present clusters with more than 8 channels, you must have two analog output cards installed in the system. Use the Output Group Select control to determine which analog output card carries the first 8 channels. Set the other card to carry the remaining channels.
How Do I Configure a Stereo Downmix for My External Surround Sound? First, make sure you have set up your external surround sound system. (See the previous page.) This function is available ONLY for clusters with 8 or fewer channels. Stereo Downmix is a hot key function, so it is set up in one of the Hot Key Configuration Menus.

Whenever you make menu changes and then exit to the Main Screen without saving into a preset, a yellow warning flag will appear in the header of the main screen to remind you to save the changes you make. How Do I Quickly Recall Presets from the Main Screen? While presets can always be recalled from the Recall Preset control on the Configuration Selection Menu, pressing Recall Preset hot keys on the Main...
How Do I Set Up a SuperPair to Monitor Intercom or Other Sources? A SuperPair is a 9th audio input pair that you can monitor along with the normally monitored audio channels. It can be any input pair. This special pair can be heard in the speakers or outputs, but is not metered on the Main Screen.
How Do I Set Up a SuperPair Volume Control? A SuperPair is a 9th audio input pair that can be heard along with the normally monitored audio channels. You can reconfigure the front panel Balance control to become a SuperPair Volume control, that will work independently of the main front panel Volume control.
How Do I Mix Any Input(s) to Any Output(s)? Any of the input channels can be mixed to any of the AES or analog outputs. The mixer controls for each AES or analog output are in the Analog or AES Output Card Configuration Menu and on the 3G SDI I/O Configuration Menu: Main Screen Configuration Selection...
How Do I Adjust Mixer Levels from the Main Screen? Any of the input channels can be mixed to any of the AES or analog outputs. Although mix levels can be set in the output configuration menus of each output card, hot keys can be used to allow you to adjust mix levels from the Main Screen.
How do I Show Mixer Output Levels on the Level Meters? If you have not done so already, you first need to set up a free mix in the output card. Please refer to How Do I Mix Any Input(s) to Any Output(s)? in this chapter and set up the needed output mix.
3. Now is also a good time to use the Channel Function control to designate the function of the channels in that pair. 4. Press the Set Clusters control to proceed to the Cluster Configuration Screen. On that screen, use the Select Cluster control, following by the Edit Cluster Label control to name the output meter pair.
How Do I Set the Clock Source? All inputs to the AMP2-16V must be synchronized to the same clock. By default, the system will automatically select a logical clock source, such as the 3G/HD/SD-SDI card in the lowest numbered slot. However, you can also set the clock source to any AES input pair or to the Reference Genlock Input.
How Do I Terminate/Unterminate AES Inputs? AES signals should have one and only one termination. This termination should physically be at the last destination of an AES coax cable. If the AMP2-16V is the last connection in a series of AES connection, then its terminations should be turned on.
How Do I Lock Entry to the Menus? In some installations, it may be advantageous to lock access to the menu system. The AMP2-16V is equipped with the ability to set a simple menu access lock. Navigate to the screen: Select Menu Lock Screen Combination Main Screen Configuration Selection...
5. When you leave the menu system and return to the Main Screen, the menu system is automatically locked again. How Do I Find Software Version Information? Occasionally, when speaking with a customer service representative, it is necessary to locate the software versions of the software in the AMP2-16V. This is simply a screen that can be called up.
CHAPTER 4: Features and Screens Introduction This chapter describes the screens and major features of the AMP2-16V Series monitors. Main Screen The AMP2-16V includes two high resolution LCD screens. This makes it easy to view video, metadata, and meters from a greater range of positions. The content of each screen is fully configurable.
Simultaneous Multi-Format Monitoring The AMP2-16V can monitor 16 channels of 3G/HD/SD-SDI, AES, analog, or optical inputs in any combination on the same level meter screen. It does not need to switch between different input port types to display them simultaneously on the meters, or to monitor them audibly.

Audio Processor Cards While the AMP2-16V comes standard with a dual input 3G/HD/SD- SDI card, it can be outfitted with up to five optional cards of various types so that it can be customized for your particular installation. 1. Dual Input 3G/HD/SD-SDI Card: This card has two selectable 3G/ HD/SD- SDI inputs, one reclocked or re-embedded 3G/HD/SD-SDI output of the selected input, and eight de-embedded AES outputs on two HD-15 connectors from the selected input.
Genlock Input To ensure the best performance, the AMP2-16V includes a Genlock input to keep all of the inputs synchronized. Note that if the Genlock input is not used, by default the AMP2-16V will automatically locate a clock source from the input cards starting with the lowest-numbered card slot.
optical input is equipped with a sample rate converter so that its clocking may be independent from the clocking of all of the other inputs. Refer to How Do I Select the Inputs I Want to Hear in the Speakers? in Chapter 3 for details.
Dolby E Line Position Display As part of the Status Data Screen, the AMP2-16V will display the line position of each Dolby E bitstream contained in a 3G/HD/SD-SDI signal, relative to the guard band. This may be shown for any or all Dolby E bitstreams simultaneously on the same screen.
Page 69
A Dolby bitstream may also be decoded and output through an optional AES Output Card or an Analog I/O Card completely independently of other monitoring. Refer to How Do I Mix Any Input(s) to Any Output(s)? in Chapter 3 for details. The Dolby Zoom feature allows you to view the Dolby metadata and the level meters simultaneously while also monitoring the Dolby audio pairs in the front panel speakers.
a) Rotate the knob to the right (clockwise) to select soloing (blue) or to the left (counterclockwise) to select muting (red). b) Press the knob to deactivate or activate the solo or mute. c) Rotate the knob one “click” at a time to select one or the other of the channels in the pair to solo or mute.
Phase Monitoring Not only can the phase relationship of any pair be monitored, but the phase between any arbitrary non-adjacent channels or pairs can also be monitored. Phase monitoring between adjacent pairs is controlled in the Monitor Mixer Configuration Menu. Arbitrary phase monitoring between any non-adjacent channels can also be set up in the Arbitrary Phase Measurement Menu.
CHAPTER 5: Menu List Introduction This chapter provides an in-depth description of all the menus and all their respective options and functions. Note: The menus are listed alphabetically for easy reference.

It provides an interface to: 1) Manage connections with ease a) Display discovered devices and streams b) Connect streams from network to local destinations c) Start, stop and monitor stream health/status 2) Enable local Brooklyn II™...
Routing to the AMP2-16V The AMP2-16V is set up by Wohler to be used as a slave rather than a master within the Dante network. Other devices, or software such as Dante Controller, are expected to be responsible for most device configurations and all audio routing.
What is in the AMP2-16V for Dante The Audinate Brooklyn II board automatically recognizes Dante networks when installed, will alert other devices of its presence and configuration, and will configure its AoIP address per DHCP or local link protocols. DHCP works best and is recommended.
Dante Device Setup The AMP2-16V’s default Dante Device Name is “BKLYN-II- …” followed by the last 6 digits of the Dante port MAC address. This name can be changed by the Dante Controller to appear that way on the network. Figure A-4: Dante Device Name Dante Device Name Figure A-5: Device Name Change...
Important: Only 48kHz audio sample rates are currently supported by the AMP2-16V. Default rate is 48kHz, which can only be changed via network reconfiguration such as Dante Controller. Connected devices must be set to the same rate. Dante Clock Selection While the Brooklyn’s internal clock is highly accurate, the AMP2-16V does not have provisions for external audio sync clocks or GPS time sources.
AES67 The AMP2-16V Brooklyn II can be configured to support multicast AES67 operation. Session Announcement Protocol (SAP) should be used. AES67 operation with Dante is limited to eight or less receive channels at a 48 kHz sample rate. 16 bit (L16) or 24 bit (L24) encoding and 125/250/333/100 usec packet times can be received.
Figure A-8: IP Address Settings The channels to be multicast are selected in the Dante Controller File menu-Create Multicast Flows window. Figure A-9: Multicast Channel Selection Device Lock There a feature whereby a remote controller can send a command to lock Dante network device configurations.

It should have its own 1Gbps router. However, at least one computer must be connected to the Ravenna network to perform configuration. Set the Ethernet IP address of the Ravenna option into the "eth1" line on the Device Configuration page. The address must be on the same subnet as the other devices on the Ravenna network.
Controller Cloud The Cloud page shows any Ravenna devices on the given network, including any Wohler devices with the Ravenna option installed. After the configuration described in the previous section, the devices you have set up should now appear on the Controller Cloud page.
Sync The Sync page allows you to program parameters relating to Precision Time Protocol (PTP) based time synchronization of network clocks of your BACH AES67 devices. For each of the devices you set up, you may check its associated Sync page.
Source Streams The Source provides in-depth information on source streams that are transmitting (sourcing) Ravenna signals from devices on the network. Check the Source tab of the source card web page. At lease one source much be turned on. Figure B-6 shows a Source page with six sources turned on. The status of each source should be green.
Stream Destinations The Destination page provides in-depth information on your destination devices that are receiving Ravenna signals on the network. Clicking the Advanced button provides additional options. Note: The Destinations must be set to ON. An AMP2-16V should have (at most) two destinations - TDM.0 and TDM.1. Figure B–7: BACH Controller Stream Destinations In the event that the Patch tab will not allow you to route to TDM.0 or TDM.1, use this tab to delete all sources routed to those destinations by clicking on the trash...
Patch Panel The Patch page enables routing of connections between listener and talker channels for devices on the network. The highlighted green square indicates a routing connection between a source or talker (left) and a destination or listener (bottom). The Web GUI will allow selection of channels to monitor from among the listeners (bottom).
