Basic Operations
Listening to the Sound
1 Turn on the amplifier and select the program source.
2 Press POWER (?/1).
The woofer turns on and the POWER indicator lights up in green.
3 Play the program source.
Adjust the VOLUME so that sound from the front speakers is not
distorted.
If it is distorted, the sound from the woofer will also be distorted.
Note
Never set the amplifier’s tone
control (BASS, TREBLE, etc.) or the
equalizer output to a high level or
input sinewaves of 20 Hz to 50 Hz
recorded on a commercially-
available test disc or special sound
(bass sound of electronic musical
instrument, pop noise of analog disc
turntable, sound with abnormally
enhanced bass, etc.) in a high level
to this unit. These actions may
cause damage to the speakers.
When a special disc containing
abnormally enhanced bass is played,
noise may be output in addition to
the original sound. In such a case,
decrease the sound level.
Note
The subwoofer output signal
(DOLBY digital (AC-3) signal) of the
digital surround processor sold
singularly is set 10 dB higher by
Dolby laboratories Licensing
Corporation. In the case of using
normally, adjust the subwoofer
level.
Note
If you turn down the volume level
of the woofer too low, the auto
power on/off function may activate,
causing the woofer to enter power
saving mode.
