I am running the Denon 3312 with a monitor audio 5.1 setup. I have two queries: 1) When watching movies with DTS the volume is a lot quieter. I've checked the settings and have made sure that I have Dynamic Volume off. Is there any reason for this? 2) Occasionally the subwoofer doesn't come on. Its happened so infrequently (three times in 8 months) so I haven't really dug around the settings. Is there anything i can quickly do to on the amp to do a test? Thanks.
