PRELIMINARY DATA SHEET

MSP 3400C

It is worth mentioning, that all spatial effects affect ampli-

tude and phase response. With the lower 4 bits, the fre-

quency response can be customized. A value of 0000bin

yields a flat response for center signals (L = R) but a high

pass function of L or R only signals. A value of 0110bin

has a flat response for L or R only signals but a lowpass

function for center signals. By using 1000bin, the fre-

quency response is automatically adapted to the sound

material by choosing an optimal high pass gain.
