minimum.
The surround mode is off.
The source encoded with a Dolby Digital or
DTS signal does not have a center channel

The level of the subwoofer is set to minimum.
Incorrect cable connections to the ANALOG
INPUTS jacks.
The internal microcomputer has been frozen
by an external electric shock (such as
lightning or excessive static electricity) or by
a power supply with low voltage.
The amplifier unit is too close to the digital or
high-frequency equipment.
Dim illumination of an indicator means that
signals encoded with the corresponding

this system. In this case, the signals are mixed
into 2 channels and reproduced from the front
speakers only.
