In addition, Logic 7 uses intelligent steering to extract widebandwidth stereo surround channels. If both side and rear speaker pairsare 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 tobe steered fully to the rear speakers, with the side surround speakers6dB lower than the rears to provide subjective rear imaging.Logic 7 contains the re-equalizer feature of the THX Cinema effect, aswell as the JBL Synthesis proprietary vocal enhancement feature. Thecombination of stereo surround information during music anddecorrelated effects, with discrete steering to the sides and rears, givesLogic 7 unrivaled performance on matrix encoded films.Parameter Initial Value RangeAUTO AZIMUTH ON ON, OFFVOCAL ENHANCE +0.0dB 0.0dB, +3.0dB, +6.0dBRE-EQUALIZER ON ON, OFFSOUNDSTAGE NEUTRAL FRONT,NEUTRAL, REAR5 SPEAKER ENHANCE OFF ON, OFFBASS ENHANCE OFF ON, OFFSURROUND ROLLOFF 11.8kHz 453Hz – 20.0kHzREAR DELAY OFFSET 15ms 0-20msSIDE LEVEL +0dB -5dB to +5dBREAR LEVEL +0dB -5dB to +5dBSUBWOOFER LVL +0dB -10dB to +10dBCUSTOM/TRIGGER ENABLE ENABLE, DISABLE
