| Logic 7 | This film sound effect reproduces musical material with maximum separa- | |||
| 
 | 
 | tion at all times, whether or not directional material is being steered. In | ||
| 
 | 
 | addition, Logic 7 uses intelligent steering to extract wide bandwidth stereo | ||
| 
 | 
 | surround channels. If both side and rear speaker pairs are available, signals | ||
| 
 | 
 | may be steered between the left side and left rear, or between the right side | ||
| 
 | 
 | and right rear. It is also possible for a signal to be steered fully to the rear | ||
| 
 | 
 | speakers, with the side surround speakers 6dB lower than the rears to | ||
| 
 | 
 | provide subjective rear imaging. | 
 | |
| 
 | 
 | Logic 7 contains the  | ||
| 
 | 
 | as Lexicon's proprietary vocal enhancement feature. The combination of | ||
| 
 | 
 | stereo surround information during music and decorrelated effects, with | ||
| 
 | 
 | discrete steering to the sides and rears, gives Logic 7 unrivaled performance | ||
| 
 | 
 | on matrix encoded films. |
