Before using your NUX MG-200, follow these steps to ensure proper setup:

2. Guitar Input: Connect your guitar to the "INPUT" jack using a standard 1/4-inch instrument cable.
3. Output to Amplifier/Mixer: Connect the "OUTPUT L/MONO" jack to your guitar amplifier or mixer using a 1/4-inch instrument cable. If using stereo, connect "OUTPUT R" as well.
4. Headphones: For silent practice, connect headphones to the "PHONES" jack.
5. AUX Input: To play along with external audio sources (e.g., MP3 player, phone), connect them to the "AUX IN" jack.
6. External Control Pedal (Optional): If using an external expression pedal or footswitch, connect it to the "CTRL 2" jack.
7. USB Connection: The "USB" port is provided for system updating. Connect the MG-200 to a computer using a USB cable for firmware updates.

Once all connections are made, power on your amplifier first, then the MG-200. When powering off, turn off the MG-200 first, then your amplifier.
