Fig. 2.12: Assignment switches of the main section

USB/2-TR TO MAIN MIX
When the USB/2-TR TO MAIN switch is depressed, the USB/2-Track input is 

assigned to the main mix, providing an additional input for tape machines, 

computers, MIDI instruments or other signal sources that do not require any 

processing. The 2-Track Out/USB recording signal are muted to avoid feedback.

(Q502: USB/2-TR TO PHONES)
Press the USB/2-TR TO PHONES/CTRL RM switch if you want to monitor 

the 2-Track or USB input via the CTRL ROOM OUT. This provides an easy 

way to monitor signals coming back from tape to ensure that they are 

recording correctly.

FX TO CTRL ROOM
If you want to monitor only the FX send signal in your headphones or monitor 

speaker(s), press the FX TO CTRL switch. This mutes the main mix signal while 

routing the FX SEND output to the monitor(s). The XENYX Q802USB and Q502USB 

do not feature this switch.

Fig. 2.13: Phantom power and control LEDs

+48 V
The red +48 V LED lights up when phantom power is on. The PHANTOM switch 

activates the phantom power supply on the XLR connectors of all mono channels. 

POWER
The POWER LED indicates that the console is powered on.

Level indicator
The high-precision 4-segment display accurately displays the relevant 

signal level.
LEVEL SETTING: To correctly set the gains of the channels, first set the LEVEL 

controls of the input channels to their center positions (0 dB). Then use the GAIN 

controls to increase the input amplification until signal peaks show 0 dB on the 

level meter.
When recording to digital recorders, the recorder’s peak meter should not go into 

overload. While analog recorders can be overloaded to some extent, creating 

only a certain amount of distortion (which is common and often desirable), 

digital recorders distort quickly when overloaded. In addition, digital distortion is 

not only undesirable, but also renders your recording completely useless.

Fig 2.14: USB connector"]

USB CONNECTOR
Connect your mixer to a computer using a standard USB cable. This enables a 

stereo signal to be sent to and from your mixer and computer. The signal sent 

from the mixer to the computer is the same as the main bus. The audio returning 

from the computer into the mixer appears directly in the main and/or control 

room bus (depending on USB/2TR to MAIN and PHONES/CTRL RM buttons).
NOTE: The mixer cannot be bus-powered via USB! Always use the included power 

adaptor to supply power to the mixer.

AC POWER IN
Connect the power supply to the 3-pin mains connector on the rear of the 

console. Use the AC adapter supplied to connect the console to the mains. 

The adapter complies with all applicable safety standards.
