 |
|
Folks,
I have three inputs that should be 'unswitched':
AOA warning
Traffic Alert
AF3400EM Engine monitor
My audio panel (PS Engineering PMA7000MS) has two unswitched inputs.
Can I tie two of the sources to one input? I think there would only be an issue if they both went off at teh same time.
Alternatively, I can put the third to a switched input and leave the switch on.
Thanks,
Ralph

Put a 510 ohm resistor inline with each input before it gets to the back of
the audio panel on the ones you will be paralelling together.
device 1 - 510 ohm- \
-------unswitched input
device 2 - 510 ohm- /
the resistors protect the other device's audio amp.
Good luck
Charles
