    Dante Device Setup The iAM1-8’s default Dante Device Name is “Wohler- …” followed by the last 6 digits of the Dante port MAC address, as shown in Figure B-2. This name can be changed by the Dante Controller to appear that way on the network, but that will not change the iAM1-8 unit name appearing on GUI pages and iAM1-8 Remote Metering or Discovery pages.

  • Page 102: Dante Clock Selection

    Dante Clock Selection While the Brooklyn’s internal clock is highly accurate, the iAM1-8 does not have provisions for external sync clocks, such as those that are GPS or media reference (video genlock or audio word clock) based. So it is generally not the best candidate to be the PTP Master Clock (commonly called the “grandfather clock”) for the...

    AES67 The iAM1-8 Brooklyn II can be configured for AES67 operation. Refer to Figure B-5. 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.

    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. iAM1-8 channel source selections are made by choosing Input Type ‘AoIP’ in the Configuration-Configure Presets page regardless of which AoIP option is installed.

    The Merging Ravenna card runs specific firmware from Merging and augmented by Wohler for use within the iAM1-8. The card will not function correctly if the user downloads and installs firmware from any source besides Wohler. The Wohler augmentation includes the ability to support 64 channels.
