3.24 LS10 Playback Sound Check
After installing and setting up the LS10—or doing a maintenance check—it is a good idea to play content
and stand in the listening room while listening to the first few minutes of the movie. Check for the
following:
•
The overall sound level is comfortable and balanced.
•
The sound quality is excellent and does not include extraneous noise.
•
The dialog is in sync with the picture being shown.
•
The surround speakers are heard at the correct level (Please note that not all content will
have surround material.)
To adjust the overall sound level in the listening room, adjust the main volume control on the audio
processor.
4.0 Audio Processing Theory
4.1 Bass Management Theory
Bass management balances the bass portion of the audio system based on the speaker configuration.
Sub-bass configurations vary from 0 to 2 subwoofers.
4.1.1 Crossed Speakers
Each channel may be combined with the LFE channel in order to extend the low range beyond what can
be heard from the channel’s speaker. The software allows you to set crossover filter frequency and slope
to best match the speaker(s). The high pass and low pass filters range from 31Hz to 160Hz, and use
either 12dB/octave or 24dB/octave.
Figure 59 illustrates how the left channel input may be divided between the left channel and the LFE
channel. Each channel works in a similar fashion. The high pass filter can optionally be bypassed.
