Hi.
My name is Bengt and I'm a user from Sweden looking for help with how to use trigger out from my Denon DAP-2500A wich is 16V DC and connect this safely to my recently bought NAD C 275BEE trigger in which is 12V DC.
As I really love my Denon DAP-2500A I don't want to do anything stupid that would burn either this or the amp. 🙁 I have measured the trigger output from DAP-2500A and found it is 16V DC without a load. According to NAD technical support I need to transform the voltage from 16V DC down to 12V DC as this is what 275BEE is built for.
Unfortunately I have received no answer from Denon in this issue and my own knowledge on how to construct this is very rusty so I realise that I need an expert advice! 🙂
Please are there any of you that can help me in this issue?
My thoughts and ideas is to construct a cable with a small "box" on it possibly with a green/red led indicator to show OK/NOK status, but this is just my vision and not an absolute must... 🙄
A great thanks in advance!

Should be easy enough. All you need is a series resistor of say 1k and a 10 to 12 volt zener diode to clamp the voltage. If you really want an LED then adding that can be done either by placing it in series with the zener and choosing a lower zener value (zener plus LED voltage to equal 12 v) or just add an LED plus resistor across the 16 volt end of the chain.
One could also drop voltage trough diodes and LEDs. For example using a lower value resistor with an LED in series, then the zener+diode across to clamp it.
The series LED would get brighter with a bigger load, (or if the output get shorted). While the other one would get dimmer.
