NOTE
Some USB devices access the USB bus frequently. To avoid dropouts and clicks in the audio signal, we strongly recommend that you do not connect other USB devices to the USB bus used by the US-122MKII. USB keyboards and mice are exceptions to this, and will probably not cause problems.
Audio connections
Connect the output signal of your mic, guitar, keyboard, or other audio device to the US-122MKII, where it will be converted into digital audio and sent via USB to your computer. Connect the output of the US-122MKII to your speakers (via an amp) or headphones, so you will be able to monitor the audio signals coming into the US-122MKII or being produced by your computer.
The balance between the input signal from the mic and guitar and the output signal from the computer should be adjusted by the MON MIX knob.
NOTE
The US-122MKII has two input channels (L, R), with a MIC IN jack (XLR) , LINE IN and LINE/GUITAR IN jack (1/4” phone jack) provided for each channel. Do not connect signals to both of these analog input jacks at the same time. If both are connected, the signal will not be correctly input to the US-122MKII.
Mic
Connect your mics to the MIC IN (L, R) jacks (XLR). If you are using a condenser mic that requires phantom power, turn on the PHANTOM switch.
