XENYX QX1202USB/QX1002USB User Manual
LEVEL SETTING:
To correctly set the gains of the channels, first set the LEVEL controls of the input
channels to their center positions. 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, digital recorders distort quickly when overloaded.
In addition, digital distortion is not only undesirable, but also renders your
recording completely useless.
◊
The CLIP-LED's of your XENYX display the level virtually independent
of frequency. A recording level of 0 dB is recommended for all
signal types.
MAIN MIX
Use the MAIN MIX fader to adjust the volume of the main out.
PHONES/CONTROL ROOM
Use the PHONES/CONTROL ROOM control to adjust the signal level of the
CONTROL ROOM and PHONES outputs.
USB/2TR TO MAIN MIX
When the USB/2TR TO MAIN MIX switch is pressed, the 2-Track and USB
inputs are assigned to the main mix, providing an additional input for MP3
players, computers, MIDI instruments or other signal sources that do not require
any processing. Pressing this button automatically mutes the 2-TR OUT/USB
recording signal.
USB/2TR TO PHONES/CTRL RM
Press the USB/2TR TO PHONES/CTRL RM switch if you want to monitor the
2-Track and USB inputs via the CTRL ROOM and PHONES outputs. A typical studio
application of this function is recording music into a digital audio workstation
(DAW) with simultaneous reproduction (see ch. 3.1).
FX TO CONTROL
If you want to monitor only the effects signal in your headphones or monitor
speaker(s), press the FX TO CTRL RM switch. Now the signal of the effects
processor can be monitored alone, and the main mix and/or 2-Track signal is no
longer present on the phone and control room outputs.

2.5 USB Connector

Fig 2.5: 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).
Insert the USB type B plug into the USB jack on the mixer, and the other end
into a free USB port on your computer. There are no required drivers, but we
recommend that PC users install the ASIO driver which can be downloaded from
behringer.com.
NOTE: The mixer cannot be bus-powered via USB! Always use the included power
adaptor to supply power to the mixer.

100 KLARK TEKNIK EFFECTS
The XENYX QX1202USB/QX1002USB features a built-in digital stereo effects
processor designed by KLARK TEKNIK. This effects processor offers a large
number of standard effects such as Hall, Chorus, Flanger, Delay and various
combination effects. Using the FX control, you can feed signals into the effects
processor. The integrated effects module has the advantage of requiring no
wiring. This way, the danger of creating ground loops or uneven signal levels is
eliminated at the outset, completely simplifying the handling.
SIGNAL and CLIP LED
The SIGNAL LED on the effects module shows the presence of a signal whose
level is high enough. This LED should always be on. However, make sure that the
CLIP LED lights up only sporadically. If it is lit constantly, you are overdriving the
effects processor, which leads to unpleasant distortion. If this occurs, turn the
FX controls down somewhat.
PROGRAM
The PROGRAM control has two functions: by turning the PROGRAM control,
you dial the number of an effect. The number of the preset you just dialed up
blinks in the display. To confirm your selection, press the PROGRAM control;
the blinking stops.
FX TO MAIN
The FX TO MAIN control feeds the effects signal into the main mix. If the control
is turned all the way counterclockwise, no effects signal is present in the sum
signal of the mixing console.
