简介：常用于测量立体声录音机、汽车立体声音响、立体声接收机等两个独立通道的平衡。

The LVC-94 is a zero-center wide angle indication type voltage comparator which indicates a value proportional to the logarithmic value of the ratio of two voltages such as stereo signal in low frequency,namely dB value.From the pointer directon of the zero center type meter,it is possible to identify which voltage is higher(between the two voltage indicated).also,the wide angle meter and equally divided dB scale assure easy reading.The instrument permits efficient measurement of the channel separation degree of stereo receiver,stereotape-recorder,car-stereo,etc.
