Terminals marked with this symbol carry electrical current of
suffi cient magnitude to constitute risk of electric shock. Use only
high-quality commercially-available speaker cables with ¼" TS
plugs pre-installed. All other installation or modifi cation should be
performed only by qualifi ed personnel.
*
This symbol, wherever it appears, alerts you to the presence of
uninsulated dangerous voltage inside the enclosure - voltage that
may be suffi cient to constitute a risk of shock.
!
This symbol, wherever it appears, alerts you to important operating
and maintenance instructions in the accompanying literature.
Please read the manual.
Caution
!
To reduce the risk of electric shock, do not remove the top cover
(or the rear section). No user serviceable parts inside. Refer servicing
to qualifi ed personnel.
Caution
!
To reduce the risk of fi re or electric shock, do not expose this
appliance to rain and moisture. The apparatus shall not be exposed
to dripping or splashing liquids and no objects fi lled with liquids,
such as vases, shall be placed on the apparatus.
Caution
!
These service instructions are for use by qualifi ed service personnel
only. To reduce the risk of electric shock do not perform any
servicing other than that contained in the operation instructions.
Repairs have to be performed by qualifi ed service personnel.
Read these instructions.
[1]
Keep these instructions.
[2]
Heed all warnings.
[3]
Follow all instructions.
[4]
Do not use this apparatus near water.
[5]
Clean only with dry cloth.
[6]
Do not block any ventilation openings. Install in accordance
[7]
with the manufacturer’s instructions.
Do not install near any heat sources such as radiators, heat
[8]
registers, stoves, or other apparatus (including amplifi ers) that
produce heat.
Do not defeat the safety purpose of the polarized or grounding-
[9]
type plug. A polarized plug has two blades with one wider
than the other. A grounding-type plug has two blades and
a third grounding prong. The wide blade or the third prong
are provided for your safety. If the provided plug does not fi t
into your outlet, consult an electrician for replacement of the
obsolete outlet.
Protect the power cord from being walked on or pinched
[10]
particularly at plugs, convenience receptacles, and the point
where they exit from the apparatus.
Use only attachments/accessories specifi ed by
[11]
the manufacturer.
Use only with the cart, stand, tripod, bracket,
[12]
or table specifi ed by the manufacturer, or
sold with the apparatus. When a cart is used,
use caution when moving the cart/apparatus
combination to avoid injury from tip-over.
Unplug this apparatus during lightning
[13]
storms or when unused for long periods of time.
Refer all servicing to qualifi ed service personnel. Servicing is
[14]
required when the apparatus has been damaged in any way,
such as power supply cord or plug is damaged, liquid has been
spilled or objects have fallen into the apparatus, the apparatus
has been exposed to rain or moisture, does not operate
normally, or has been dropped.
The apparatus shall be connected to a MAINS socket outlet
[15]
with a protective earthing connection.
Where the MAINS plug or an appliance coupler is used as the
[16]
disconnect device, the disconnect device shall remain
readily operable.

FBQ Feedback Detection System
The FBQ Feedback Detection System, integrated into
the graphic equalizer, is one of the most outstanding
characteristics of this mixing console. This ingenious circuitry
lets you immediately recognize and eliminate feedback
frequencies. The FBQ Feedback Detection System uses the
LEDs in the frequency band faders of the graphic EQ to
indicate the critical frequencies. This way, what once used to
be a labor-intensive search for feedback frequencies is now
an activity that even a child could master.
The microphone channels feature high-end XENYX Mic
Preamps that compare well with costly outboard preamps
in terms of sound quality and dynamics and boast the
following features:
130 dB dynamic range for an incredible amount of
•
headroom
A bandwidth ranging from below 10 Hz to over 200 kHz
•
for crystal-clear reproduction of even the finest nuances
The extremely low-noise and distortion-free circuitry
•
guarantees absolutely natural and transparent signal
reproduction
They are perfectly matched to every conceivable
•
microphone with up to 60 dB gain and +48 volt phantom
power supply
They enable you to use the greatly extended dynamic
•
range of your 24-bit/192 kHz HD recorder to the full,
thereby maintaining optimal audio quality
“British EQ”
The equalizers used for the XENYX Series are based on
the legendary circuitry of top-notch consoles made in
Britain, which are renowned throughout the world for their
incredibly warm and musical sound character. Even with
extreme gain settings these equalizers ensure outstanding
audio properties.
Multi-effects processor
Additionally, your XENYX mixing console has an effects
processor with 24-bit A/D and D/A converters included,
which gives you 100 presets producing first-class reverb,
delay and modulation effects plus numerous multi-effects in
excellent audio quality.
The XENYX mixing consoles are equipped with a state-
of-the-art switched-mode power supply (
SMPS
). Unlike
conventional circuitry an SMPS provides an optimum supply
current regardless of the input voltage. And thanks to its
considerably higher efficiency a switched-mode power
supply uses less energy than conventional power supplies.
USB/Audio interface
The USB interface supplied with the unit is a perfect match
for the XENYX Series and serves as a powerful recording
interface to your PC or MAC. It supports the digital
transmission of signals on up to four channels with max.
48 kHz and extremely low latency. When wired to the
CD/TAPE INPUT and OUTPUT connectors, the interface
transfers the stereo mix from the console directly to a
computer. Both the recording signal and the playback signal
from the computer can be monitored at the same time.
In this way, you can use several recording runs to produce
complete multi-track recordings.
CAUTION!
!
We would like to draw your attention to the fact that
◊
extreme volumes may damage your hearing and/or
your headphones or loudspeakers. Turn the MAIN MIX
faders and the PHONES control in the main section
fully down before you switch on the unit. Always be
careful to set the appropriate volume.
General mixing console functions
1.1
A mixing console fulfils three main functions:
Signal processing
◊
:
Preamplification
Microphones convert sound waves into voltage that
has to be amplified several-fold; then, this voltage is
turned into sound that is reproduced in a loudspeaker.
Because micro phone capsules are very delicate in their
construction, output voltage is very low and therefore
susceptible to interference. Therefore, mic signal voltage
is amplified directly at the mixer input to a higher signal
level that is less prone to interference. This higher,
interference-safe signal level has to be achieved through
amplification using an amplifier of the highest quality
in order to amplify the signal and add as little noise to
it as possible. The XENYX Mic Preamp performs this
role beautifully, leaving no traces of noise or sound
coloration. Interference that could take place at the
preamplification level could affect signal quality and
purity, and would then be passed on to all other devices,
resulting in inaccurate sounding program during
recording or playback.
Level-setting
Signals fed into the mixer using a DI-box (
Direct
Injection
) or the output of a sound card or a keyboard,
often have to be adjusted to the operating level of your
mixing console.
