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.
