Allen & Heath QU-16 – real USB round-trip latency (DAW use)

Qu Qu DAW Integration

Hi everyone,

sorry if this topic has already been discussed. If so, please point me to the right thread.

I’m trying to find real measured round trip latency (RTL) data for the Allen & Heath QU-16 when used as a USB audio interface with a DAW.

If anyone has tested it (for example with RTL Utility or loopback), could you share the numbers? A typical setup is ok (for example 48 kHz sample rate and 128 buffer size), but any sample rate and buffer size are fine.

For context, I’m looking for the full input → DAW → output latency, not just internal mixer or monitoring delay. No further processing on the QU-16 nor in the DAW, just in and out.

Thanks in advance for any measurements or reliable sources.

I hope someone can provide you with some real world results.

That being said, it would be relatively easy to measure this yourself using something like the free software OpenSoundMeter.

You really only need to compare two measurements: 1) the time it takes to measure the audio traveling just through the console (ie no audio being sent to the DAW) and your measurement system and 2) the time it takes to measure the audio traveling through the console, out to the DAW, and back out of the console and through your measurement system. The difference in these two measurements is the total time the audio path to/from the DAW adds.
