While the unit is connected to the MM8003 via the bus, MM8003 cannot be powered ON/OFF when the POWER ON/OFF button is being held down. 2. Pop noise is heard when Audyssey is run when the unit is being bi-amped. 3. When receiving the remote control command of input from the front, the unit goes into ZONE input mode and becomes awkward to use. The operability is to be improved. Solution: 1.
