Surround Effect
The maximum value of the surround effect is set with pins 15 and 16.
• The surround effect is increased by connecting an external resistor to pin 15.
• The surround effect is decreased by connecting an external resistor to pin 16.
• The device may be used with no external resistors on pins 15 and 16.
The level of the surround effect is controlled by pins 1 to 3.
