<p>A stereo acoustic image amplifier comprises a first operation unit for subtracting a second input signal from a first input signal to generate a difference signal, a filter for filtering the difference signal from the first operation unit to generate a filter difference signal, a second operation unit for adding the first input signal and the filter difference signal from the filter to generate a first output signal, and a third operation unit for subtracting from the second input signal the filter difference signal from the filter, the filter comprising a low-pass filter having a cut-off frequency of 5 kHz and a high-pass filter having a cut-off frequency of 200 Hz. <IMAGE></p> |
