• To conform to cinema standard used to playback movies and DVDs, an input
signal -20 dBFS (Full Scale) should produce 85 dB SPL from each individual
satellite and 95 dB SPL from the subwoofer. A +10 dB gain switch is provided on 
the LSR6312SP SUB 
DIRECT IN which can be used to conform to this gain structure.
• If you are listening to music, you may wish to calibrate the sub without the 10 dB 
boost to produce the same SPL as each of the satellites.
