delay that varies with frequency, resulting in phase
distortion where the low-frequency sound is delayed or
muffled by the conflict with other channels. With the
Phase Control mode switched on, this receiver can
reproduce powerful bass sound without deteriorating the
quality of the original sound (see illustration below).
