Hi, 1. Can anyone tell me what Dynamic Range Compression is ? What level is the best do I need to setup in my Denon AVR 1602 receiver. Off - Low - Med or High ? Is there any information website about it ? 2. How do I setup my Denon AVR 1602 to a maximum performance and realistic surround sound.I currently using a complete local made (unbranded) 120Watt Front speaker (4-6 Ohm),surround speaker and 8" Active subwoofer. 3. There are a few of my DTS movies are giving me a noisy breaking sound even I do a setup my DVD player and Receiver properly. I use an optical cable. Dolby Digital are perfectly working and some others DTS movie are also perfectly working.Is it my DVD player or something wrong with my system setup ? Thanks.
