Tight AV AU-X2O-DA (Dante DAC) Measurements

[peniku8]

Here are a few measurements of the Tight AV Dante to XLR dongle done via DVS.
Due to DVS not being recognized by FlexASIO, the measurements are a little different than the ones I usually provide.
I had two instances of REW running: One with the Cosmos ADC and one on DVS. Cosmos was running 384KHz while the Dante network was set to 96KHz.
The device was powered by a TP-Link PoE Switch that was connected to my PC's 2nd Ethernet port (and nothing else).

Frequency response (via white noise, hence the slight wonkiness):

Nicely flat well into the low infrasonics. Good start!


THD+N@0dBFS: -90,1dB

Same measurement at 50Hz since I couldn't sweep FR vs THD:

Dynamic Range: 108,8dB

I'm especially happy about the lack of mains hum. The noise spectrum is just fairly even noise, which is quite inoffensive psychoacoustically.

And well, that already wraps up my measurements for the Tight AV Dante DAC.
I'll be using this to integrate analog amplifiers into a Dante-networked live sound rig.
Cheers!

$300 but I suppose that's OK for something so super niche.

Sad how Dante stuff is still scam priced yet the protocol itself is just boring old packets over ethernet!

Where are you seeing that price? I paid half of that

Crummy coupling capacitors, I reckon. I don't know why people insist on using MLCCs in the signal path.

What sensitivity / input impedance setting on the Cosmos ADC were you using? That may well make a difference. Since this is not a high-performance DAC, I would try the lowest sensitivity (10 Vrms) setting with 3 kOhms and change.

Seeing the series of odd order harmonics now, this might also just be on the onset of clipping. I forgot to check at -1dBFS.
I had the Scaler between DAC and ADC for half of the measurements, but that died at some point so I think the DAC was connected directly to the ADC for the high level measurements (Scaler stuck in high gain mode). I had the ADC set to 10Vrms sensitivity. The dongle's maximum output levels are 18dBU (~6Vrms) and Zout in the manual is 150 Ohm.
