• Mono Mode: Ideal for single-person recordings, providing clear and natural sound.
• Stereo Mode: Suitable for two-person interviews or immersive soundscapes. Requires both transmitters to be active.
• Safety Track Mode: Records a secondary audio track at -6dB to prevent audio clipping in case of unexpected loud sounds.
