The audio frequency response curve is shown below. The audio signal was fed into a dummy microphone circuit and into the microphone connector. The input required to produce 30 percent modulation level was measured. SB Technology FR531-2 -60 -55 -50 -45 -40 -35 -30 100100010000 Frequency dBmV audio response Applicant: SB Telcom Co., Ltd.
