Q Xpander Processors
Monolithic IC MM1434
Outline
From ordinary stereo signal input, each of the sound sources is expanded spatially to reproduce sound with a
sense of immediacy.
Algorithms developed by Q Sound are faithfully implemented in an IC produced by Mitsumi.
Features
1. Sound spreading is easily modified using an external VR.
2. Few external components required through use of active filters based on Mitsumi's bipolar technology.
3. Low cost achieved through improvements from previous model (MM1354) to VA.
Package
SOP-16A (MM1434XFBE)
Applications
Sound enhancement processor.

Note 1 : When R1 is chosen 22kΩ, the operating voltage Q Xpander becomes narrower. But the input
dynamic range becomes wider. The character is illustrated in the typical performance
characteristics (3).

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.

Note 4 : The Q Xpander effect (the spread effect) is adjusted with VR.
Note ± : We recommend using the regulator for the power supply which occurs the ripple.
Note 6 : The mute signal which switches off the power supply of a power amplifier that is connected with
MM1434 appears in the 10 terminal.
Note 7 : When the power supply is switched on, the pop noise occur. We recommend muting the pop noise
