PURPOSE:To provide a sound monitor capable of confirming the position of the correct sound image in the sound system. CONSTITUTION:The signal level difference between audio signals of the right and left channels and audio signals between the front and rear channels is detected by means of subtraction circuits 14H, 16H and 14V, 16V Based on the signal level difference detection result, the x-y scope is driven in the horizontal and vertical directions. Thus the display position of the x-y scope is made displaced in the volume balance in all directions. |
