    Hi Yves,

    Our transport protocols were designed as point-to-point Layer 2 connections. Use in Layer 3 or converged networks, even with dedicated VLANs, is known to be problematic. It’s been done, and discussed several times on this forum, but not something we can recommend or guarantee.

    This article explains some of the reasons and limitations:

    Hi Yves,

    Can you tell us more about your system requirement? Do you need single mode fibre between the Surface and MixRack, or between two dLive systems?
    dLive does not support Dante for the Surface to MixRack connection I’m afraid.
    The easiest way to run single mode between a Surface and MixRack would be to use external Cat to fibre Gigabit converters, there are many on the market from super affordable to military grade equipment.

    Hi Yves,

    No, the fibreACE card is multimode only. Although it utilises standard SFP modules internally, we do not recommend replacing these, as we cannot guarantee performance nor reliability.

    If you need to connect over single mode, you can consider the superMADI card which comes with external SFP slots and can certainly take single mode SFPs and fibre. It would give you access to the same 128×128 channels of audio, however you would need multiple fibre cables as the MADI standard can only support 32ch @96kHz or 64ch @48kHz for each link. The other disadvantage is that fibreACE can tunnel L3 network data (network bridge), superMADI cannot.

    Hi Alex,

    A correction if I may.
    The FX sends in SQ are mono busses. If you configure an Avantis to match the bus structure of an SQ (4 mono FX sends, 12 stereo Aux/Grp, 3 stereo Mtx, 1 PAFL, LR) you should still have 4 spare mixes remaining in your Mixer Config screen.

    This might not sound like much, however one of the advantages of Avantis is that the bus architecture is much more configurable.
    So for example, a Monitor engineer might need a lot of Aux mixes, but no Matrix (even no LR perhaps). You could get say 12 mono + 12 stereo monitor mixes depending on the number of FX in use.
    Conversely, at FOH you might need very little in terms of Auxes, but plenty of Matrix and FX sends.

    I can confirm that ZEDi mixers have been tested on macOS Monterey (both Intel and Apple M silicon). No drivers required on macOS as the product is Core Audio compliant.

    @eotsskleet Has anything changed in your setup that could cause a network conflict? Try removing networked laptops, routers, access points etc. and switching off the network bridge if running Dante. Also worth checking that you are running the latest version of dLive firmware.
    If the problem still occurs, then please contact an A&H distributor or raise a ticket with our Support team at support.allen-heath.com and attach your log files.

    Looking at our evaluation data, the input frequency response goes indeed higher on SQ. When routed to a digital output, it’s flat up to 40kHz with a mic gain up to 40dB and no PAD. The PAD introduces a -1dB at 40kHz. Line outputs are -2dB at 40kHz. Our specs list max deviation in dB within the 20Hz-20kHz spectrum because that’s a common measurement in the industry.

    As your post refers to anti-aliasing filters, I should add that a benefit of setting higher anti-aliasing filters, other than frequency response, is that you can set a gentler slope for the filter, resulting in less phase distortion in the audible spectrum (often perceived as high frequency smearing). At 44.1kHz for example, you are forced to use steeper filters causing more phase distortion.

    Hi BC,
    The two ports on the gigaACE card are designed for redundancy purposes only. They cannot be connected to two separate devices I’m afraid.
    You can consider fitting a Waves card to the SQ5, and using Waves Soundgrid for the connection between the two mixers. For example, use I/O 1-64 on the Waves card for recording / virtual soundcheck, and use I/O 65-128 for tielines to the SQ5.
    Alternatively you could move the DX Hub to the SQ5, and fit an SLink card for connecting to the Avantis.

    Brian is correct. If the Internal Network Bridge switch on the Dante card is set to On, this will link the dLive control network with the Dante network. At this point, connecting both the Dante card and the dLive Network port to the same LAN will cause a conflict. With the Internal Network Bridge On, you only need a single connection from the Dante card to ‘see’ both Dante and the dLive.

    Avantis and dLive don’t allow a direct patch of the Talkback output. The method described above by Ash, via an Aux bus, would be my suggestion.

    Hi Bartjan,

    The DX gigaACE SLink white paper is a recommended read if you’re interested, however it doesn’t go into the specifics of different gigaACE implementations as we didn’t want to confuse users more than necessary 🙂

    Søren is correct. Although we generally use the term gigaACE for high channel count 96kHz audio connections, there are differences in the protocol implementation depending on device type.

    – dLive MixRack to dLive Surface using built-in gigaACE ports – over 300×300 channels of audio and encapsulated TCP/IP data for A&H control + third party data
    – dLive to dLive using gigaACE cards – 128×128 channels of audio and encapsulated TCP/IP data for A&H control + third party data (with network bridge On)
    – dLive to dLive using gigaACE cards with Gain Sharing active – 128×128 channels of audio and layer 2 preamp control, no TCP/IP data
    – SLink to DX Hub / GX4816 – 128×128 channels of audio and layer 2 preamp control, no TCP/IP data
    – SLink to gigaACE card – 128×128 channels of audio
    – SLink to SLink – 128×128 channels of audio

    USB drives / keys formatted FAT32 are generally ok. Have you tried formatting the drive from the desk?

    DT Preamp Control displays the preamp control firmware (V1.4).
    Dante Controller displays the Dante firmware product version (V1.0.4).
    Both are correct at the time of writing.
    Does Dante Controller show valid subscriptions (green ticks) for the DT168 to M-DL-DANT64 patch?

    Hi Alan,

    Which Dante card are you using in the DM48, and can you confirm the firmware version (product version) of this card too?
