Dante 64×64 Card – Flow Limit

[Aled]

Quick question – the Dante 64×64 card – what’s the flow limit?

My assumption is that it’s using the Audinate Dante HC chip (the Brooklyn II chip only supports 32×32 @ 96kHz but the card supports 64×64 @ 96kHz) – in which case it’d be 64 flows (imposed by A&H – not the chip limit, which would be 256×256)?

Can anyone either confirm/clear up my assumption?

Thanks!

For network it is 64×64 at 48 96 khz

Dante Virtuel soundcard is limited 32 ch at96 khz

Thanks for your reply Showtime – but are you saying that the card can support 64 x 64 flows or channels?

I know that the Dante 64×64 Card can support 64 channels – that’s in the spec. What I’m asking is if it can support 64 separate flows (or 32? or 16?) – which determines the number of devices you can send from, rather than the number of channels.

I’m not interested in Dante Virtual Soundcard at the moment, thanks.

As far as I remember is the flow limit only valid for multicast scenarios
and there is a 32×32 limit since every flow is reserving 2 audio channels

but without multicast, no limit I think

Spoke to Allen & Heath for those that are interested:

The Dante 64×64 Card allows 64 channels of audio over 64 separate flows and is based on the Dante HC technology (not chip, my mistake!)

That is, you could send 1 channel of audio from 64 separate devices to the card – although it wouldn’t be terribly efficient (wasting 3/4 of bandwidth as each unicast flow encapsulates 4 channels of audio)

I just got the Dante card for the SQ and it has 128 flows. That number is what is reported in Dante Controller so I presume it is correct. As you say, that is enough for every channel in the 64×64 config to have its own flow – amazing.
