Connecting Devices

To the GO:MIXER PRO, connect the instrument, mic, or audio player etc. that you want to record.
Connect the included USB cable first to the GO:MIXER PRO and then to your smartphone (p. 6).
• If you are unable to record on your smartphone, slowly repeat step 2 once again.
• To prevent malfunction and equipment failure, always turn down the volume, and turn off all the units before making any connections.
• Before turning the unit on/off, always be sure to turn the volume down. Even with the volume turned down, you might hear some sound when switching the unit on/off. However, this is normal and does not indicate a malfunction.
• If operating on batteries, the POWER indicator blinks when the batteries run low. If you continue using the unit in this state, the power automatically turns off after approximately one minute. Replace the battery as soon as possible.
• In some cases, noise might be heard when you connect a smartphone, or when you start up or operate an app.
