[USB 2.0] jack

Connects to a computer via a USB cable. The signal from the 
STEREO L/R buses is output to the computer. (This signal is 
not affected by the [STEREO] master fader.) A USB driver 
might be required for computer input/output. You can down-
load the driver from the following Yamaha website, and 
install it on your computer.

USB

] switch is on while DAW software is being used, a 

loop is formed and feedback or howling may result.

[USB 2.0] Connection Precautions

Be sure to observe the following points when connecting to a 
computer’s [USB 2.0] interface. Failure to observe these rules 
can result in computer freezes/hang-ups and possibly data 
loss or corruption. If the mixer or computer does hang up, 
restart the application and/or computer and turn the power to 
the mixer off and then on again.

NOTICE

• Use an A/B type USB cable. The cable should be no 

more than 1.5 meters long. A USB 3.0 cable cannot be 
used.

• Be sure to wake the computer from sleep/suspended/

standby mode before making a connection to the com-
puter’s [USB 2.0] connector.

• Connect the mixer to the computer before turning the 

mixer power on.

• Always perform the following two operations before turn-

ing the mixer’s power on or off, or connecting or discon-
necting the USB cable.

- Exit all applications.

- Confirm that no data is being sent from the mixer.

• Allow at least six (6) seconds between turning the mixer 

on or off, and plugging or unplugging the USB cable.
