18 XENYX Q1202USB/Q1002USB/Q802USB/Q502USB 19 Quick Start Guide
(EN)  Step 2: Controls
This chapter describes the various control elements 
of your mixing console. All controls, switches and 
connectors will be discussed in detail.
(1)  MIC – Each mono input channel oers a 
balanced microphone input via the XLR 
connector and also features switchable 
+48/+15 V phantom power supply for 
condenser microphones. TheXENYX preamps 
provide undistorted and noise-free gain 
as is typically known only from costly 
outboardpreamps.
(2)  LINE IN – Each mono input also features 
a balanced line input on a ¼" connector. 
Unbalanceddevices (mono jacks) can also be 
connected to these inputs. Please remember 
that you can only use either the microphone 
or the line input of a channel at any one time. 
You can never use both simultaneously!
(3)  GAIN – Use the GAIN control to adjust the 
input gain. This control should always be 
turned fully counterclockwise whenever you 
connect or disconnect a signal source to one of 
the inputs.
(4)  EQUALIZER – All mono input channels 
include a 3-band equalizer, except for the 
Q502USB, whichis equipped with a 2-band 
EQ. All bands provide boost or cut of up to 
15dB. In the central position, theequalizer 
isinactive.
(5)  LOW CUT – In addition, the mono channels 
(Q1002USBand Q1202USB) are equipped 
with a steep LOWCUT lter (slope at 18 dB/
oct., -3dB at 75 Hz) designed to eliminate 
unwanted low-frequency signalcomponents.
(6)  FX (Q802USB/Q1002USB/Q1202USB 
only) – FX sends (or AUX sends) enable you 
to feed signals via a variable control from 
one or more channels and sum these signals 
to a bus. Thebus appears at the console’s FX 
send output and can be fed from there to 
an external eects device. The return from 
the eects unit is then brought back into 
the console on the aux return connectors 
(Q802USB) or normal channel inputs. Each FX 
send is mono and features up to +15 dB gain.
(7)  PAN – The PAN control determines the 
position of the channel signal within 
the stereo image. Thiscontrol features 
a constant-power characteristic, which 
means the signal is always maintained at a 
constant level, irrespective of position in the 
stereopanorama.
(8)  LEVEL – The LEVEL control determines the 
level of the channel signal in the main mix.
(9)  CLIP – The CLIP LED’s of the mono channels 
illuminate when the input signal is driven 
too high, which could cause distortion. Ifthis 
happens, use the GAIN control to reduce 
the preamp level until the LED does not 
lightanymore.
(10)  LINE IN – Each stereo channel has two 
balanced line level inputs on ¼" jacks for left 
and right channels. If only the jack marked “L” 
(left) is used, the channel operates in mono. 
The stereo channels are designed to handle 
typical line level signals. Bothinputs will also 
accept unbalanced jacks.
(11)  FX – The FX sends of the stereo channels 
function similar to those of the mono 
channels. However, since the FX send buses 
are both mono, amono sum is rst taken from 
the stereo input before it is sent to the FX bus. 
The Q502USB is not equipped with FXsends.
(12)  BAL – The BAL(ANCE) control determines the 
levels of left and right input signals relative 
to each other before both signals are then 
routed to the main stereo mix bus. If a channel 
is operated in mono via the left line input, 
this control has the same function as the PAN 
control used in the mono channels.
(13)  +4/-10 – The stereo inputs of the XENYX 
Q1002USB and Q1202USB have an input 
sensitivity switch which selects between 
+4dBu and -10 dBV. At -10 dBV (home-
recording level), the input is more sensitive 
(requires less level to drive it) than at +4 dBu 
(studiolevel).
(14)  STEREO AUX RETURN – Q802USB only: 
theSTEREO AUX RETURN connectors are used 
to bring the output of the external eects 
device (whose input is derived from the 
aux sends) back into the console. You can 
instead use these connectors as additional 
inputs, but any eects device will then have 
to be brought back into the console via a 
normal stereo channel. This does, however, 
give you the ability to use the channel EQ on 
the eects return signal if you wish. If only 
the left connector is used, the AUX RETURN 
automatically operates in mono. Use the AUX 
RETURN control to determine how much of the 
eects signal is sent to the main mix.
(15)  FX SEND – The FX SEND output (does not 
apply for Q502USB) should be connected 
to the input of an external eects unit. 
The post-fader FX signal you created using 
the input channel FX controls is sent to the 
eects unit via the FX SEND ouput. Usethe 
FXSEND control of the main section to 
adjust the overall send level (Q1002USB and 
Q1202USBonly).
(16)  PHONES/CTRL ROOM – The stereo PHONES 
jack (at the top of the connector panel) 
iswhere you connect headphones. The 
unbalanced CTRLROOM OUT jacks carry the 
summed eects and main mix signals, as 
well as soloed channel signals. ThePHONES/
CTRL ROOM control adjusts the level of both 
headphones and main monitor outputs. 
TheQ502USB is not equipped with control 
roomoutputs.
(17)  MAIN MIX – The MAIN OUT connectors are 
unbalanced mono jacks. The main mix signal 
appears here at a level of 0 dBu. TheMAIN 
MIX fader adjusts the volume of these 
outputs. TheXENYX Q802USB and Q502USB 
mixing consoles feature a rotary control for 
thispurpose.
(18)  2-TRACK INPUT – The 2-TRACK INPUTs are 
used to bring an external signal source (e.g.CD 
player, tapedeck, etc.) into the console. 
They can also be used as a standard stereo 
line input, so the output of a second XENYX 
or BEHRINGER ULTRALINK PRO MX882 can 
beconnected.
(19)  2-TRACK OUTPUT – These connectors are 
wired in parallel with the MAIN OUT and carry 
the main mix signal (unbalanced). Connectthe 
2-TRACK OUTPUT to the inputs of your 
recording device. Theoutput level is adjusted 
via the high-precision MAIN MIX fader or 
rotary control (Q802USB/Q502USB).
(20)  USB/2-TR to MAIN –  When pressed, 
thisbutton sends the audio from the 
USB and 2-TRACK inputs to the main mix 
(Q502USBonly).
(21)  USB/2-TR to PHONES – When pressed, 
thisbutton sends the audio from the USB and 
2-TRACK inputs to the PHONES jack (Q502USB 
only). 
(22)  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 FXSEND output to the monitor(s). 
The XENYX 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 eect 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 +15V 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. 
Alwaysuse the included power adapter to supply 
power to the mixer.
