Optical Direct for Reactors
#1
Anyone know if there is an optical direct mode for the Reactors?

You don’t need it. You can already turn latency down to 60ms which appears to be the lowest that they support.

Question..
Low latency means less sound quality?

I'm more interested in removing the need for the devialet app... I want to use a pair of reactors for surround speakers in my home theater.  I'm worried that the devialet app will reset the volume to 35 randomly right when my wife/kids want to use the system...

"Low latency means less sound quality?" - I don't believe so, but it does mean less stability between the Reactors, so you need a better connection. That's why I recommend Ethernet.

I think you can do that straight away, but you will need to use the app (or your hands) to adjust the volume.

I confirm that there is no equivalent of the Premier "optical direct" mode on Reactor. Different architectures do not allow for ultra low latencies on the Reactor.

Hi!  Devialet sent me a procedure to activate an "optical direct" mode like feature on my Reactors.  I am currently testing it.  Will let you know how it works.

How much lower is the latency? What’s the procedure?

Based on my testing, its worse than 60ms... :-(  I'm waiting to hear back from them on the actual measurement.  I'm also waiting to hear back on if I can post the procedure.  On the bright side, all of my reactors are stable now.  No audio issues, no random changing of volume, etc.

Confirmed from Devialet that the latency will be less than 1ms when put into optical direct mode.  The limitation with the reactor implementation is that there is no way to choose which channel the speaker will play from the optical stream.  So you need to split the L/R channels before the signal reaches the reactors.  Using a simple optical splitter will give you 2 reactors playing a stereo mix, not true L/R.  

Below is the procedure to turn on Custom Mode ("optical direct") on a reactor:

Reactor Custom Mode
* Mini-jack connection only (both Analog and Optical)
* Volume fixed to 100%
* Volume setting available on sensor buttons
* BT + Airplay disabled
* Hardware reset only (protected from Power cycling)


Step1: Factory Reset
— Plug-in your Reactor and wait for the LED light to turn white or green
— Long Press on the back button (10sec)
— LED should turn purple and produce a distinctive short sound
— After ~1mn LED will fade in White then turn solid Green

Step 2: Entering Custom mode
— Press simultaneously (+) and (-) top button for 10 seconds
— LED will blink White then turn Green again when you release
— Plug-in your mini-jack (optical or analog) to the back of Reactor within one minute
— LED will turn from Green to solid White
— Unplug Reactor for 10 seconds and plug it back
— That’s it! Reactor is ready in Custom Mode!

— You can check that the setup worked by pressing on the
Bluetooth logo on top of the speaker
—> The LED should not turn Blue

The instructions are straight from Devialet.  Enjoy!
