Optical Direct for Reactors

[njaiswal]

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!
