I just bought some wireless headphone Sennheiser RS140. for my 80 year old mother that is hard of hearing. I want her to use the headphone so i do not have to turn up the speaker volume as we are watching TV. Is there a RCA Audio out port on the back of the 990 that is active no matter if you are using the Sat TV, DVD or FM radio etc. for the headphones to plug into.

Thanks Scott
