Q802USB and Q502USB do not feature this switch.
23. +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.
24. POWER – The POWER LED indicates that the console is powered on.
25. LEVEL INDICATOR – The high-precision 4-segment display accurately displays the relevant signal level.
26. COMP – This knob adjusts the amount of compression effect on the channel.
27. PHANTOM – Press this knob to send +48 V of phantom power to the XLR inputs for use with condenser microphones.
The Q502USB supplies +15 V of phantom power.
28. USB/2-TR TO PHONES/CTRL RM – button routes USB/2-Track playback to PHONES/CTRL ROOM.
29. USB/2-TR TO MAIN MIX – button routes USB/2-Track playback to MAIN MIX and mutes the 2-TR OUT/USB recording
signal.
30. USB CONNECTOR – Connect your mixer to a computer using a standard USB cable.
31. AC POWER IN – Connect the included power cable here.
The mixer cannot be bus-powered via USB. Always use the included power adapter to supply power to the mixer.
Step 3: 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. The peak meters of your XENYX display the level virtually independent of frequency. A recording level of 0 dB is
recommended for all signal types.
