Application Circuit

Q Surround Processor MM1454

*1 Resistor Tolerance ±1%

*2 Capacitor Tolerance ±5%

*3 The mute signal which switches off the power supply of a power amplifier that is connected with MM1454

appears in the 4 terminal. (NOTE 7)

*4 The pop noise which occurs in a moment of the power supply switching on is reduced by connecting the

capacitor (10uF) between 2PIN and GND. But if the reduced pop noise cause trouble for your application, we

recommend muting the pop noise by the power amplifier that is connected with MM1454.

*5 SW1: A QSurround Mode

SW2: B Bypass Mode
