Latency on optical s/pdif audio output

[TheTwickerman]

Hi folks,

 

just connected the TT to the home cinema. I opted for optical s/pdif connection. 

 

There's a disconcerting lag on the audio.

 

Is this a feature of the optical audio connection?

 

Will it be better if I swap to an analogue connection?

 

Thanks for any suggestions.

The Amplifi optical output to my Bose Soundtouch 30 does the same thing, it's delayed from the timing of my playing. I always assumed it was the decoder in the Bose, but maybe not...

Correction, it was the 1/4" phones output to the Bose 1/8" auxiliary input. I remember being surprised by the latency with that connection...

I found that the analogue connections (including the headphone socket) are ok.

 

So that's what I am using now.

 

I don't know whether the delay is in the encoding in the TT or the decoding in the amp (or both) - but either way, it's pretty useless!

Many consumer-grade audio devices introduce latency with their connections because of the way they process audio. They weren't really designed with real-time monitoring in mind. Even if you're syncing with video, a 10ms latency is probably not going to be noticeable, but it can be when playing guitar through a system. I've used my AMPLIFi TT's S/PDIF connection plugged directly into an audio interface, and there was no latency.

That's what I am hoping, because I will be using it as a recording interface too.
