Channel Level 
Channel level calibration will allow the equalization of the volume levels of
each speaker to make up for differences in speaker characteristics and 
distances from the listener to the speakers. Best results will be achieved
using a Sound Pressure Level (SPL) meter, and an external analog tone or
pink noise generator. Set the SPL Meter to C Weighting and Slow Response.
Place the meter at your listening position and adjust each speaker for an
equal response (An SPL of 75 dB is recommended). 
Speaker Crossover (X-Over)
This sets the frequency at which bass tones are filtered from the speaker 
channel selected and sent to the subwoofer(s). The crossover point is the 
frequency at which the amount of information in the subwoofer and main 
speaker(s) is equal. Set this according to the capabilities of the speakers 
and/or subwoofer(s). When a crossover frequency for a speaker is set, the 
crossover frequency and above is sent to the affected speaker, while the 
crossover frequency and below is sent to the subwoofer(s). 
Each speaker in the system (except for the subwoofer) has a specific 
crossover assigned to it. Each speaker has the ability to have a unique 
crossover frequency set for it. While the subwoofer does not have its own 
unique crossover, the subwoofer low frequency content is determined by 
the crossover settings of all other speakers in the system. All low frequency 
material below the crossover frequency set point for each speaker is sent to 
the subwoofer(s).
LFE (Dolby/DTS) 
This setting is used to increase or decrease the subwoofer level for 
multichannel bitstreams that contain an Low Frequency Effects channel. The
subwoofer signal may need to be increased or decreased depending on the 
room or installation. Usually this will be set to 0 dB (default). Note that this 
effects only the separate LFE (.1) or subwoofer channel available on source 
material. There is no effect on the reproduction of normal bass from the 
front, center, or surround channels.
