: CCB is SANYO's original bus format. 
  All bus addresses are managed by SANYO for this format.

The LV25200M integrates an optimal reception system for varying reception conditions plus AM NC functions 
that support reception worldwide. It also reduces the number of external components required.

The LA2655V is a sound field recreation IC that is optimal for audio equipment and that includes the Plus Sound 
algorithm.
The LA2655V is optimal for use in radio/cassette players, personal computers, TV sets, and other consumer 
audio products including mini-compo systems.
The Plus Sound algorithm corrects for both delays and attenuations of the high and low frequency signals due to 
the characteristics of the speakers and creates audio with extreme clarity.

■ 

Plus Sound algorithm

■ 

Clear Surround signal processing

■ 

Variable clear level effect (using external components)
