I think I have the levels pretty even when just one is active, because I tend to look for the little RX on the face of the IFD to tell which frequency I'm hearing.  But I don't think I've tried to decide if the volume of one frequency changes when receiving a second.

All of which is probably too many words to say, "I dunno."  But I'm happy with it overall.

Thanks David.
The real issue I have with the audio volumes with the AMX240/IFD540 set from the 540, is that the volume levels are very different with and without Standby Monitoring.

After customized adjusting of the volumes for Active Comm-1 and Standby Comm-1 channels (using the 540 audio controls), deactivating the Standby "Monitor" function reverts the volume on active Comm-1 way too loud. 
 
IOW, the 540 audio levels ought to be the same with Standby-Monitor function ON or OFF, but they are not.  

Seems like the 240 Monitor switch is introducing excessive attenuation onto both channels when Monitor is activated.
