The Main Out jacks L/R on the Gigcaster 5 are 1/4" TS unbalanced.
Output Impedance: Main Out Left Right: 1 k ohms
Best to use only 1/4" TS unbalanced cables for proper connectivity.
NOTE: If you need to connect the MAIN OUT (L, R) jacks of the Gigcaster 5 to a balanced input, consider using a device that converts unbalanced audio signals to balanced, such as a direct box. Be sure to check the specifications of the receiving device to ensure compatibility.
