speakers (standard) assure full-scale home theater sound. When
playing back laser discs or video software that have been
recorded in Dolby Surround, astonishingly realistic sound
surrounds the listener to create a new level of audio/visual
entertainment.
Independent control of the four sound channels allows the listener
to enjoy the same type of sound reproduction experienced in
movie theaters. Voices are reproduced in the front and center
sound field, while ambient sounds like cars and crowds are
reproduced on all sides of the listener for an incredibly lifelike
audio/video experience. PIease read the following carefully to
“tune” the system’s output to match the characteristics of your
listening space.

balance of speaker sound levels.

The unit is equipped with a built-in test signal generator called a
noise sequencer for easy balance adjustment of all 5 channels.
The sequencer outputs a noise signal that “travels” from channel
to channel, enabling the simple adjustment of sound level to
achieve, at the listening position, the same apparent loudness
from each channel.

the noise signal together. However, only the sound level of one
surround speaker displayed as “S-R” or ‘S-l-” can be adjusted.
● When the sequencer outputs a noise signal, a clicking sound
might be heard from the speakers due to the characteristics of
the circuit. This is not malfunction.
