The BY-XM6 S2 series adopts advanced Adaptive Frequency Hopping (AFH) wireless signal transmission technology, which can make the BY-XM6 S2 avoid the disturbed hop frequency parts automatically to realize stable signal transmission in the range of up to 100m. Featuring a high-quality capsule and signal processing circuit with a signal-to-noise over 84dB and a distortion rate less than 0.1%, the BY-XM6 S2 captures and delivers Hi-fi and low-noise audio. With vivid and easy-to-read OLED display on transmitter and receiver, users can adjust the signal transmission precisely. And the transmitter is designed with a built-in omnidirectional microphone, so users can clip the transmitter on the collar to pick up sounds, while they can also plug a lavalier microphone into transmitter’s MIC IN input jack for sound capturing. Plus, this microphone kit is equipped with both 3.5mm TRS-TRS audio cable and 3.5mm TRS-TRRS audio cable. So it can work with your DSLR or mirrorless camera, smartphone and computer. When you record two sound sources simultaneously, BY-XM6 S2 will be your best choice.
