| Attenuation or the ability to reduce the Dts Trim by at least 10 points probably is there in case some users have speakers/sub that might come apart under strong (Dts) LFE impacts! |
This, and the fact that dts CD's do NOT require the 10db lfe boost, only DTS movies. Therefore, when playing a dts cd, you have the ability to back off the lfe by 10db to obtain the proper lfe levels.
