I have an Anthem MRX520 AV Receiver set up as a 5.1 system (subwoofer in bypass mode)
If I listen to a Blu ray with a 5.1 mix I hear the subwoofer as it is being fed via the subwoofer/LFE output of the AV Amp (the discreet .1 part of the mix)
However, if I listen to a 2.0 mix I still hear the subwoofer which I didn't expect
What is happening here?
Is it that if the .1 channel is absent the AV Amp just sends the LF from R/L to the subwoofer output anyhow?
If it is undesired I guess one could create a config with the sw switched off
