Documentation Trigger Ports and IR - DirectStream MKII

I am looking to integrate the MKII in my remote control setup. Is there a documentation about the Trigger ports of the MKII? Also, where is the IR receiver located?

The remote sensor is just to the right of the menu button. Currectly the trigger ports are not active pending future UI firmware developement.

This is where I installed the emitter for our Control4 system.

Cool, thanks! I set my volume fix to 100 and only use the Sonore opticalRendu (USB) as a source. So other than on/off there is not much to control from my side. I will think about installing an ermitter.

Thanks! I hope to be able to use the trigger ports for on/off command for the DS MK II

Resurrecting this to see if I understand the back of the MKII. Are both triggers OUTPUT only? If so, that is incredibly dumb.

Contact PS Audio and ask. Or try it.

I was really more so hoping someone had experience using them and could answer the question. If they really are output only I don’t think I want to experiment. I’ll just give PS Audio a call tomorrow.

This the perfect application of the acronym RTFM. No malicious intent! Just good humor.:blush:

Technical writers need loving too.

I did. I think I am in disbelief that they are both outputs. The manual doesn’t speak much on the triggers, but what little is there defines them as outputs.

I asked for specs of trigger outputs (I think it was on on of PSA’s amps) and got a strangely unhelpful reply.

  • are they a pulse trigger or a permanently on when on thing (i.e. once the trigger has triggered devices to go on, would unplugging just the trigger leave the other devices on or not)?
  • If a pulse trigger what pulse width would be required for the downstream stuff to notice?
  • positive or negative going?
  • correct wiring of the trigger sockets? (mono or stereo mini jack and if stereo which terminals used?

I never did get an answer.

I guess triggers (and PS Link) are top secret information. Fun.

The trigger is a steady state signal that is present when the source is on. Example when BHK preamp is on and any delay time is met will turn on the amp.

The specs from the BHK amp manual may give you a clue how PS Auidio triggers work:

“12 volt trigger”

“For those users wishing to remotely turn on and off the BHK, we provide a trigger input. This input accepts from 5 to 12 volts. When a positive voltage within limits is applied, the amplifier will come out of standby and turn on. Removing the voltage puts the BHK in standby mode.”

My issue is that there does not seem to be any trigger input on the DAC. That seems insane to me given the DAC is rarely the top of the stack. I get it if you are using it as a preamp, but with a preamp it is nonsense to only have outputs.

17

How would you ideally use the triggers?

18

I would turn on the DAC when I power on the system at the preamp. The problem now is that if I turn on the DAC with the remote it turns on the transport too. Now I realize that seems trivial, but I’d rather not have the transport on all the time when I rarely use it.

19

Why not flip the transport’s power switch to off given you rarely use it anyway?

Would this not solved your issue?

It would. Just don’t understand why I even have to.
