XENYX Q1202USB/Q1002USB/Q802USB/Q502USB Controls
(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 offers a
balanced microphone input via the XLR
connector and also features switchable
+48/+15 V phantom power supply for
condenser microphones. The XENYX preamps
provide undistorted and noise-free gain
as is typically known only from costly
outboard preamps.
(2) LINE IN – Each mono input also features
a balanced line input on a ¼" connector.
Unbalanced devices (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, which is equipped with a 2-band
EQ. All bands provide boost or cut of up to
15 dB. In the central position, the equalizer
is inactive.
(5) LOW CUT – In addition, the mono channels
(Q1002USB and Q1202USB) are equipped
with a steep LOW CUT filter (slope at 18 dB/
oct., -3 dB at 75 Hz) designed to eliminate
unwanted low-frequency signal components.
(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. The bus appears at the console's FX
send output and can be fed from there to
an external effects device. The return from
the effects 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. This control features a
constant-power characteristic, which means
the signal is always maintained at a
constant level, irrespective of position in the
stereo panorama.
(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. If this
happens, use the GAIN control to reduce
the preamp level until the LED does not
light anymore.
LINE IN – Each stereo channel has two
(10)
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. Both inputs will also
accept unbalanced jacks.
FX – The FX sends of the stereo channels
(11)
function similar to those of the mono
channels. However, since the FX send buses
are both mono, a mono sum is first taken from
the stereo input before it is sent to the FX bus.
The Q502USB is not equipped with FXsends.
BAL – The BAL(ANCE) control determines the
(12)
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.
+4/-10 – The stereo inputs of the
(13)
XENYX Q1002USB and Q1202USB have
an input sensitivity switch which selects
between +4 dBu and -10 dBV. At -10 dBV
(home-recording level), the input is more
sensitive (requires less level to drive it) than at
+4 dBu (studio level).
STEREO AUX RETURN – Q802USB only:
(14)
the STEREO AUX RETURN connectors are used
to bring the output of the external effects
device (whose input is derived from the
aux sends) back into the console. You can
instead use these connectors as additional
inputs, but any effects 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 effects 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 effects signal is sent to the main mix.
FX SEND – The FX SEND output (does not
(15)
apply for Q502USB) should be connected
to the input of an external effects unit.
The post-fader FX signal you created using
the input channel FX controls is sent to the
effects unit via the FX SEND ouput. Use the
FX SEND control of the main section to
adjust the overall send level (Q1002USB and
Q1202USB only).
