Note 1 : f=1kHz, It is input voltage that THD of output voltage is 1%. Then the signals that are inputted in SG1

and SG2 are in phase. The difference of phase between the left input signal and the right one is 0°.

Note 2 : f=1kHz, It is input voltage that THD of output voltage is 1%. The difference of phase between the left

input signal and the right one is 180°.

Note 3 : High-Level input voltage of BYP terminal (3pin) (Q Xpander MODE)

Note 4 : Low-Level input voltage of BYP terminal (3pin) (bypass MODE)

Note 5 : Input current of BYP terminal (3pin) (Vbyp=5V)

Note 6 : Input current of BYP terminal (3pin) (Vbyp=0v)

Note 7 : The mute signal which switches off the power supply of a power amplifier that is connected with

MM1434 appears in the 10 terminal.

When the power supply of MM1434 is switched off, the pop noise occur.

We recommend muting the pop noise. The way is that the power supply of MM1434 is switched off

after the power supply of the follow power amplifier is switched off.

Note 8 : We recommend using the regulator for the power supply which occurs the ripple.

Note 9 : When the signal is input in SG1, it is the ratio of 7pin output voltage to 9pin output voltage.

Note 10 : When the signal is input in SG2, it is the ratio of 9pin output voltage to 7pin output voltage.
