* 

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.

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.
Place the power cord so that it is protected from being walked 

{10}� 

on and sharp edges. Be sure that the power cord is protected 
particularly at plugs, convenience receptacles and the point 
where it exits from the apparatus.
The apparatus shall be connected to a MAINS socket outlet 

{11}� 

with a protective earthing connection.
Where the MAINS plug or an appliance coupler is used as 

{12}� 

the disconnect device, the disconnect device shall remain 
readily operable.
Only use attachments/accessories specifi ed by the 

{13}� 

manufacturer.
Use only with the cart, stand, tripod, bracket, 

{14}� 

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 

{15}� 

storms or when unused for long periods of time.
Refer all servicing to qualifi ed service personnel. Servicing is 

{16}� 

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 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:

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.

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.

The FBQ Feedback Detection System integrated 

into the graphic EQ of your 1832FX is one of this 

mixer’s most outstanding features.

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.

We have added another useful feature to the 

XENYX 1832FX: the Voice Canceller.
The Voice Canceller is a filter circuitry that filters 

out vocal portions from a track. Therefore, this mixing 

console is ideally suited for use as a karaoke machine. This 

feature is also an optimal solution for singers who need 

accompanying music for their rehearsals.

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.

A mixing console fulfils three main functions:

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 construc-

tion, 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. Interfer-

ence 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.
