Thanks! for the comment

But I am talking the real time TV watching and there are 20s of channels, I am switching over time to time and having them all recorded and then later played back or working on ADs shedules for EACH programs, seems even harder than HAVING the ADs watched with loud sound!

I heard that there are VR-1s which can do the jobs as there are having a pre-set level of volume and when source volume gets elevated, they bring it back to pre-set volume?

The trouble is:

WHERE ARE THEY? WHICH PLACE IN DOHA?
