4.3 Connecting to Recording Devices

Connect the receiver to your recording device using the appropriate cable:

• For Cameras (DSLR, Camcorder, GoPro): Use the 3.5mm TRS to TRS camera cable. Connect one end to the receiver's 3.5mm output and the other to your camera's microphone input.
• For Smartphones (Android, iPhone): Use the 3.5mm TRS to TRRS phone cable. Connect the TRS end to the receiver's 3.5mm output and the TRRS end to your smartphone's headphone/microphone jack. Note: iPhones without a 3.5mm jack will require an official Lightning to 3.5mm adapter (not included). Android phones with USB-C only may require a USB-C to 3.5mm adapter (not included).
• For Laptops/PCs: Use the 3.5mm TRS to TRS camera cable or a suitable adapter if your computer has separate microphone and headphone jacks.
