Hi there - does anybody know how the 12V trigger logic works on the Port i.e. once it outputs audio trigger on - when no audio trigger off - any delays etc.

Kind regards, Emil

    ElGuapo34,

    No, the 12V trigger on the NR1607 is an output that can be used to control other devices connected to the receiver.

     

    Jacfucious,

    I don’t know which ONKYO you have. Typically, receivers will not respond to a 12V trigger. Amplifiers may respond to a 12V trigger input from PORT.

    Hi all, I built the following box with 6 inputs for the 12v output from the Sonos and one output to the amp, using diodes inside to protect the Sonos.  My amp had signal detect, i.e. it would turn on when it detected audio on an input but I found often watching TV the amp would turn off because the audio was too low and I also found the amp slow to turn on especially for music tracks with quiet starts. 
    With the 12v input it now works perfectly and turns on within seconds.  My distribution amp is the Rotel RMB-1512

     

     

    This is great. I have the same challenge with a 6-zone set-up on the Rotel RMB-1512, but couldn’t find any kind of hub for the triggers coming off the Ports. Seems that a commercial solution doesn’t exist. Does your box also limit the output voltage going to your amp when you have multiple Ports sending a trigger simultaneously?

    I just purchased a Port and connected it to Rotel RB1572 amplifier.  I have tried both stereo and mono cables, the trigger mode on the amp is “On”, and the cable is plugged into the “in” port on the amp.  The power switch for the amp is “On”.  The trigger from the Port does not turn off the amp as it should after 2 minutes.  Any suggestions? 

    Did you end up getting this to work? Trying to do the same with my Rotel RA-12 and having no luck.

    The RA-12 does not support being controlled by a 12V trigger. The RA-12’s trigger output could be used to control external equipment.

    My NAD C326BEE Stereo Integrated Amplifier has a “12V trigger out,” described in the manual as follows,

    +12V TRIGGER OUT: The +12V TRIGGER OUT is used for controlling
    external equipment that is equipped with a +12V trigger input. This
    output will be 12V when the C 326BEE is ON and 0V when the unit is
    either OFF.

    Am I right in assuming that the Port’s 12V trigger will not control this amp because the amp has only a “trigger out”?

    Thanks.

    I intend to use one of these to power my amp on/off using the 12V trigger from the port.

    Assume this will work and the amp will power off 2 mins after music stops as per reply above?

     

    Malkie52, did you purchase the Audiophonics trigger? If so, did it work and how long did it take to receive the item?

    I made a simple device using ESP32 to control my Amp from the 12v trigger on the Sonos Port.

      Yes if your amp has a 12v trigger input it will do this but…… if your amp is like my Denon amp and does NOT have this input then the device I mention above will do the trick. Effectively you leave the amp switched on the and the trigger effectively switches on the mains supply. When you stop the music the relay opens after 2 mins and switches of the mains supply and thereby the amp. Works perfectly for me  

      So if I used the Audiophonics 12v device, the only way my AVR would turn on is from the use of the port, so basically my Apple TV wouldn’t be able to turn it on any longer like it currently does.

      Hi, I’ve ordered this ‘AUDIOPHONICS Trigger 12V 230V Slave Power Supply Device’, but only now (when already received the device) I’ve noticed, that my Marantz uses 2 pins AC IN cable and socked (C17/C18). While AUDIOPHONICS devices comes with C13/C14 plugs. I was trying to connect some other 3pins cable to AUDIOPHONICS and then connect it to Marantz, but seems no power comes in via it… Maybe there is some solution for this? Thanks.
