Brou -
There is an excellent review of the various audio panels... early post on this thread.
My config is single IFD540 & AMX240. The 240 is supposed to "allow the pilot to listen to standbyfrequencies with automatic muting when the active frequency is inuse"
However, mine (and perhaps others on the forum) does not do this as advertised - both channels are active in Monitor Mode. There are also problems with the Comm-1 Monitor Standby Function causing severe unwanted attenuation of the Active Comm-1 channel while in Monitor Mode.
My take on the PMA450 is it offers more high tech spatial localization of up to 4 simultaneous audio inputs, so as to be able to tell them apart.
I use my SL30 as Comm-2 with its internal Monitor capability of Standby frequency. 121.5 is always my SL30 Active Channel, and I listen to ATIS for example on SL30 Standby Monitor (stuttering audio).
Hope this helps.
