Using BoomX-D2 Pro with iPhone: For iPhone users, ensure the Lightning to 3.5mm adapter cable is MFI certified (for iPhone/iPod/iPad). Without MFI certification, audio recording on your iPhone may not function properly. Minimizing Background Noise with DSLR: When connecting BoomX-D2 Pro to DSLR cameras like Sony, Canon, or Fujifilm, set the camera recording volume to the minimum to reduce background noise effectively. Adjusting Mic Volume Separately: While you can adjust the level on each transmitter, using stereo mode with a stereo splitter cable is recommended. This way, each mic has its own channel, and you can control the volume on your mixer or recording device individually. Understanding Safety Track: Safety Track records a secondary audio track as a backup with a volume of -6 dB. This serves as a precaution in case of issues such as overexposure, ensuring your audio remains protected.
