Abstract (en)
A system for enhancing sound signals at a relatively high sonic level power input and comparatively low signal power level output which are relatively adjusted so that the signal is enhanced when reproduced. The input includes a capacitor (402) for creating a reverberation effect in the signal and an adjustable power level varying device (402) for causing a second harmonic effect in the signal. When the system is used in a multichannel sound system, a low pass filter is connected between channels for causing a phantom center channel effect in the sound signal. <IMAGE>
