Setup

Power Connection

Connect the provided power adapter to the mixer's power input and then to a suitable electrical outlet. Ensure the power switch is in the OFF position before connecting.

Input Connections

The CT120 mixer features 12 channels, each with XLR and 1/4-inch line inputs. Connect your microphones, instruments, or other audio sources to the appropriate input jacks.
