There have been plenty of questions regarding DJing with Sonos regarding the 70ms latency. Someone once posted this:
”1) If you can get the output of your DJ thingy into the Playbar via it's optical input then the audio would NOT be delayed. If you had 2 Play units bonded as surrounds then they would also play audio not delayed (but the signal would NOT be Dolby Digital 5.1 so they would barely get used.
2) Any other way of getting audio into Sonos - via line in on Connect, Connect:amp or Play 5 would be subject to an audio delay
3) If you GROUPED other Plays to a Playbar and played your DJing via the Playbar the audio played through the GROUPED speakers would be delayed by 70ms.”
Is the statement in (1) true and if so can one also plug directly into the optical in of a Beam to achieve the same.

Hi John! Statement 1 is very true. All of the Home Theater Sonos speakers are designed to have minimal latency on the TV audio input. That would be the Beam, Playbar, Playbase, and Amp (note that the Amp has an analog input too, which will have a 75 ms delay since it’s not a TV input). Technically there is a slight delay, but it’s not noticeable when watching TV, trying to sync the video and audio together, so I imagine it’d be similarly unnoticed with DJ applications.
