CHAPTER 1: Installation Introduction Overview The iAM-MIX intelligent adaptable monitors are 1RU multichannel multisource audio monitors with multiple standard copper connections and multiple SFP module options facilitating high density coax and optical fiber connections. They feature direct integration capability with Evertz, Tally, and Grass Valley routers for channel name synchronization. The iAM-MIX may also accept Audio over IP signals via an Ethernet connector.
Important: By design, this monitor will only plug into a three-prong outlet for your safety. If the plug does not fit into the outlet, contact an electrician to replace the obsolete outlet. 7. Protect the power cord from being walked on or pinched, particularly at plug connection source on the equipment and at the socket. 8. Use only the attachments/accessories specified by the manufacturer. 9. Unplug the equipment during lightning storms or when unused for long periods of time. 10.
Heat Dissipation The ambient temperature inside the mounting enclosure should not exceed 40° Celsius (104° Fahrenheit). Adjacent devices can be rack mounted (or stacked) in proximity to the unit if this temperature is not exceeded. Otherwise, allow a 1RU (1.75”/44.45mm) space above and below the unit for air circulation. Important : Heat generated by the class D power amplifiers, power supplies, and other components is vented by slots in the sides and back of the unit.
Compliance FCC This equipment has been tested and found to comply with the limits for a Class A digital device, pursuant to part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference when the equipment is operated in a commercial environment. This equipment generates, uses, and can radiate radio frequency energy and, if not installed and used in accordance with the instruction manual, may cause harmful interference to radio communications.
CHAPTER 2: Local Operation Startup The iAM-MIX-8 and iAM-MIX-16 units (and their variants) take about a minute to become operational after power is applied. During that time, several status messages are shown spanning the displays on the front panel. Front Panel The iAM-MIX-8 front panel is shown in Figure 2-1. The iAM-MIX-16 front panel is shown in Figure 2-2.

CHAPTER 4: Using the iAM-MIX Web GUI The iAM-MIX Web GUI allows you to customize the monitor’s configuration to suit your needs. The default Presets configure the channels of each source in a consecutive fashion. If the default configuration of the iAM-MIX suits your needs and you prefer to use it that way, then you do not need to use the iAM-MIX Web GUI.
Figure 4–1: Host IP Settings Close the control panel and reboot the host computer after making an IP address change to be sure the change takes effect. Either reconnect to the installed network or continue with this direct connection to access the iAMMIX Web GUI. Network Connection When connected to a network, the iAM-MIX address will need to be changed to another address in order to be compatible with the address assignments for that particular network.
Dashboard Throughout the iAM-MIX Web GUI, other pages are a click or two away on the left side. System Overview on this Dashboard page shows all Preset configurations at a glance. Figure 4–2: Dashboard Preset Overview The currently selected Preset for local operation is shown full color. Other stored, but not selected, Presets have gray backgrounds. The top row shows which sources are used in the Preset. The middle row shows which channel numbers are assigned to each control strip.
Figure 4–3: Dashboard Device Overview Sign In Only authorized users should be allowed to make Preset and network changes. Anybody can view the status of iAM-MIX units on the network, but logging in with a password is required to make any changes. When logging in is required to make a change, the page shown in Figure 4-4 will appear. Alternatively, login can be done at any time by clicking on Administrative Account selection in the upper right portion of the browser page and clicking Log In.
basis to suit your security needs. You will remain logged in until the browser window is closed or the session is disconnected physically or virtually, or Log Out by clicking Administrator Account in the upper right of any page. Channel Naming Each channel can be assigned a name in the configuration database. There is a separate set of names for each input type, selected by the upper row check boxes.
Configuration - Setup Factory default Presets are provided for each input type and the first eight or sixteen channels in consecutive order. Default mixes are left for oddnumbered channels and right for even-numbered channels. If one of those simple arrangements works for your application, there is no need to change any of your Presets, since the monitor can be left set to that Preset. The Configuration page is where the setup can be made in virtually any arrangement.
4. The Input Type box switches between the available inputs. Inputs are enabled by software licenses and the optical input must have an SFP module installed for it to work. The iAM-MIX loops the selected incoming MADI stream to both coax and fiber outputs (if installed). 5. Check the Clock Reference box for the input to serve as clock sync reference. An SDI or MADI stream may exhibit some audible clicks if it is not synchronized externally and is not selected as the clock reference.
Configuration – Named Presets Change Preset names on this page. Click Save to store the new name(s).
Configuration – Device Management This page is used to manage integration with Grass Valley systems to automatically set the text in the labels on the channel strips. Grass Valley integration can be used for AES and SDI audio monitoring interfaces. Evertz and Tally integrations do not require any setup. They are used for the MADI audio monitoring interface. Figure 4–8: Device Management To set up Grass Valley integration, use the following steps: 1.

APPENDIX B: Dante Network Setup Introduction Installing the iAM-MIX into an existing and functioning Dante network is virtually plug and play. The iAM-MIX rear panel AoIP jack supports 1Gb/s and 100Mb/s Ethernet devices in Dante Audio over IP network configurations. iAM-MIX channel source selections are made by choosing Input Type ‘AoIP’ in the Configuration-Configure Presets page regardless of which AoIP option is installed.
documentation for specific network and device setup information. What is in the iAM-MIX 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. There is no need to set a static address for the iAM-MIX Dante port, so no address entry method is provided in the iAM-MIX for Dante network setup.
Dante Device Setup The iAM-MIX’s default Dante Device Name is “BKLYN-II- …” 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-MIX unit name appearing on GUI pages and iAM-MIX remote metering or discovery pages.
Figure B–4: Rename iAM-MIX Other changes such as Latency settings can be made by the Dante Controller 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-MIX.
as the master. Figure B–5: Clock Selection Channel Names The iAM-MIX uses the BKLYN-II default network channel names of Tx 01-16 and Rx 01-64. The network controller can change these names as desired, but iAM-MIX channel selections will remain as the original default numbers, unless changed in the Channel Naming - AoIP page. Note these iAM-MIX internal channel names are not passed to the Dante network for discovery purposes, and are internal to the iAM-MIX.
AES67 The iAM-MIX 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 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 devices’ configurations. The iAM-MIX does not implement the Device Lock command at this time.
Dante Firmware Upgrades Wohler iAM-MIX 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-MIX software/firmware is tested with the latest Dante code release. Therefore it is strongly recommended that iAM-MIX and Dante software/ firmware be updated at the same time to ensure compatibility and support of the latest features.
APPENDIX C: Ravenna Network Setup Introduction Installing the iAM-AUDIO into an existing and functioning Ravenna network 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 channel source selections are made by choosing Input Type ‘AoIP’ in the Configuration-Configure Presets page regardless of which AoIP option is installed.
