XENYX Mic Preamp
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:

“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.

Additionally, your XENYX mixing console has an effects processor 

with 24-bit A/D and D/A converters included, which gives you 

16 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 X1832USB 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 X1832USB: 

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.

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.
Frequency response correction
Using the equalizers found in each channel strip, you can simply, quickly and 

effectively adjust the way a signal sounds.

Effects mixing
In addition to the effects processor contained in your mixer, using the insert 

connectors on the mono channels and both aux busses lets you insert additional 

signal processors into your signal path.

Signal distribution: 
Individual signals adjusted at each channel strip are laid out at the aux 

sends and returns, and are either fed into external effects processors or fed 

back to the internal effects processor. Then, the signals are brought back 

into the main mix either via the aux return connectors or via direct internal 

wiring. The mix for the on-stage musicians is also created using the aux 

sends (monitor mix). Similarly, for example, signals for recording equipment, 

power ampli fiers, headphones and 2-track outputs can also be taken.
